Chevrolet Lanos (Sens). Antifreeze is leaking from the expansion tank (antifreeze level drops)

Stages of replacing coolant in a Chevrolet Lanos

Replacing the coolant is divided into several stages; in addition to the main ones, which include draining and filling, it is recommended to flush the system. Since it is not possible to completely drain the old antifreeze from the system.

This model was produced in different countries under different car brands, as well as with different model names and minor design differences. Therefore, the replacement instructions will be applicable for the following varieties:

• Chevrolet Lanos;
• Daewoo Lanos;
• Daewoo Sens;
• FSO Lanos (FSO Lanos);
• ZAZ Lanos;
• ZAZ Sens;
• ZAZ Chance;
• Doninvest Assol.

The most popular is the 1.5 liter petrol engine. But you can also find cars with 1.6, 1.4, 1.3 liter engines installed, also running on gasoline.

Coolant drain

To accurately drain coolant from a Chevrolet Lanos, it is better to perform work in a pit or overpass. This will make it easier to remove the engine protection so that the drained antifreeze does not splash around, but flows smoothly into the container.

If there is no hole and you are not very worried about the fact that the protection will be in traces of smudges, then you can reach the drain plug from the engine compartment. Therefore, we put the car on a flat surface, wait for the engine to cool down and start draining:

We find the drain plug, unscrew it, after placing a container under it (Fig. 1). The drain hole is located on the left side, at the bottom of the radiator, when viewed from the pit. Accordingly, if you stand facing the car and do everything from the engine compartment, the traffic jam will be on the right.

Unfortunately, it will not be possible to drain antifreeze from the block on a Chevrolet Lanos with a popular 1.5 liter engine; it does not have a drain hole. Therefore, about 2 liters of old fluid remains in the cooling system.

Flushing the cooling system

Flushing with distilled water is necessary to completely remove old antifreeze, as well as to flush out deposits in the cooling system. Without performing this procedure, the properties and service life of the new liquid being poured may deteriorate.

To perform this operation, it is necessary to close the drain valve and put the expansion tank in place. After this, you can pour distilled water into it until it comes out of the removed hose going to the throttle assembly. This is necessary to allow air to escape from the system.

Next, put the hose in place and add water to the middle of the tank. We start the engine and wait until it warms up to operating temperature. After reaching temperature, the thermostat will open and water will flow through a large circle of the cooling system.

That's it, the liquid has passed through the entire system, now you can turn off the engine, wait until it cools down and drain it. We repeat this operation several times until the drained water is clear.

Filling without air pockets

The flushed system is completely ready for filling with new antifreeze. But since it is impossible to drain completely distilled water from the Chevrolet Lanos system, it is best to use a concentrate as a new fluid. It can be diluted, taking into account the remaining residue.

After diluting the concentrate with this in mind, we begin pouring it. The filling steps will be exactly the same as we did when washing. That is, we fill it into the expansion tank until new antifreeze flows from the pipe going to the throttle.

This will prevent the formation of air pockets in the cooling system. Next, put the hose in place and continue to fill to the middle level in the tank. After that, we start the car, warm it up, and turn it off. After cooling, check the level again and top up if necessary.

Attention! The coolant must be replaced after 60,000 km or 3 years of vehicle operation or after engine repair. Operating the system filled with water will result in failure of the water pump!

Table 1.15 Recommended coolants for use

Filling the cooling system is performed in the following order:

— Unscrew the cap from the expansion tank; open the radiator drain valve and drain the old coolant (Fig. 1.26);

— Unscrew the drain plug in the engine cylinder block and drain the old coolant located in the engine cooling jacket (Fig. 1.28);

Rice. 1.27. Engine block coolant drain plug

— Screw in the drain plug in the engine cylinder block;

— Slowly pour coolant (about 7.0 l) into the neck of the expansion tank to the level between the upper and lower marks marked on the side surface of the tank (Fig. 1.29);

— Close the neck of the tank;

— Start the engine and let it idle for 1 ... 2 minutes until the thermostat opens (the pipes going to the radiator should become hot) and the air pockets are removed;

— After the engine has cooled, check the coolant level. If the level is below normal and there are no signs of leakage in the cooling system, add fluid.

How long can coolant be stored and when should it be changed?

The shelf life of high-quality coolant is from three to five years. Antifreezes remain operational for two years, or 60-80 thousand km of car mileage (according to car and antifreeze manufacturers). Some antifreezes can withstand 5 years of operation and 100-250 thousand kilometers. The shelf life and frequency of fluid replacement are usually indicated on the packaging. And yet, during operation, coolants gradually lose their properties: due to the activation of additives and a decrease in the alkalinity reserve, aggressiveness towards rubber and metals increases, and pricing increases.

The coolant must be replaced if there is a loss of color saturation, a change in color (if it has turned red), separation, or the appearance of flakes in it. Seasonal alternation of water and antifreeze is detrimental to the latter: the additives, interacting with the scale of the cooling system, quickly turn into sludge, and the coolant “ages” ahead of schedule. If during operation the drop in level was replenished with water, the properties of the coolant are lost faster. You can extend the service life of the coolant (by about a year) by adding 1.0 -1.5 liters of concentrate to the cooling system.

Why change the coolant?

Coolant ages in the same way as all technical fluids. And if the lubricity of the liquid is insufficient, the pump may fail.

Are antifreeze and antifreeze the same thing?

Antifreeze is one of the brands of coolants (coolants). Its name is an abbreviation of the name of the department “Technology of Organic Synthesis” (TOS), where it was developed, and the ending “ol”, which in chemistry denotes belonging to the group of alcohols. Antifreeze is usually called domestic coolant. The term “antifreeze” comes from the English word “Antifreeze,” which translates as “prevents freezing.”

Sometimes on the packaging there is another inscription “Cooling Water” (coolant). “Antifreeze” is a more general concept: something that does not freeze.

What are antifreezes made of?

Modern antifreezes are low-freezing aqueous solutions of polyhydric alcohols - ethylene glycols. Pure ethylene glycol is an oily liquid with a boiling point of 196°C and a freezing point of minus 12.3°C. The amount of ethylene glycol in the coolant is usually 52-64%, and the freezing point of the resulting solutions ranges from minus 32 to minus 70 ° C. To eliminate such disadvantages of the coolant as aggressiveness towards rubber and metals, low lubricating properties, anti-corrosion agents are introduced into them , antifoam and other additives.

Is it possible to mix liquids of different brands and colors?

The possibility of mixing different coolants depends on the compatibility of the additives. Their packages may differ in the composition and amount of substances used, since different manufacturers use different additives. In one case, these are inorganic compounds - boronitride, amine and phosphate inhibitors, in the other

— Imported chemical compounds of a new generation. Due to the interaction of additives, the anti-corrosion and lubricating properties of the antifreeze mixture, as a rule, deteriorate. Bring it on! To accelerated failure of engine parts. It is for this reason that mixing different coolants is not recommended. With foreign-made antifreezes, incompatibility with other coolants is observed less frequently and, as a rule, this is indicated on the label. And yet it would be correct to assume that coolant cannot be mixed. The opinion that “blue” with “blue” or “red” with “red” can be mixed is also erroneous: the colors of different coolants depend on the dye used and do not affect the compatibility of the liquid.

Why are counterfeit antifreeze dangerous?

If the coolant contains an insufficient amount of ethylene glycol, this is not so bad: when “hypercooled” it turns into a loose ice slurry, which, unlike frozen water, does not expand and does not damage the engine cooling system. After starting the engine, it quickly turns into a liquid state. Much more dangerous is the corrosive aggressiveness of counterfeits: they literally “devour” copper radiator tubes and soldered seams. Corroding even steel and cast iron parts.

Unscrupulous coolant manufacturers, in an effort to quickly sell their “product,” make it as cheap as possible. Substitutes for ethylene glycol are used, for example, diethylene glycol or polyglycols.

Coolant purchased somewhere on the highway may even turn out to be a solution of salt and sugar, tinted with dye. It is not difficult to guess what the use of such “antifreeze” can lead to.

How to determine freezing temperature

The freezing point of antifreeze during vehicle operation, as a rule, does not change. A decrease in the liquid level can occur due to partial boiling away of water from the antifreeze or a leak in the cooling system. Then you have to add something to the expansion tank. The tendency of a liquid mixture to freeze can be determined using a hydrometer. It is better if this device is calibrated in degrees Celsius. The density of standard coolant with a freezing temperature of minus 40°C is 1.100-1.1150 g/cm:.

How to distinguish high-quality antifreeze from low-quality one?

Unfortunately, this is impossible without laboratory tests. Monitoring the density with a hydrometer and checking the fat content by touch does not always allow one to determine the quality of products in this group, and they are dangerous, since ethylene glycol is poisonous! You can’t conduct full corrosion tests in the kitchen either. However, you can partially reduce the risk of purchasing low-quality antifreeze by following some recommendations. Firstly, coolant should be purchased in specialized stores and from manufacturers who have a quality certificate for their product. Secondly, you need to carefully study the label: it should have the technical specifications number and (or) the phrase: “Complies with the requirements of GOST 28084-89” (for domestically produced coolant). Imported antifreezes must indicate the manufacturer's standard number. Thirdly, the manufacturer’s coordinates, production date and expiration date are required. It is also desirable to indicate the compatibility of the product with other coolants. Many components of high-quality antifreeze, for example, benzoic acid, are produced or purchased only abroad. It is clear that a good coolant cannot cost the same as water.

How to prepare coolant from concentrate?

When diluting antifreeze concentrate, you cannot use tap, well or spring water.

— Its hardness and impurities can negatively affect the additives contained in the coolant. The use of chemical water softeners is highly undesirable. It is better to use only distilled or, as a last resort, boiled, settled water. It is necessary to strictly follow the proportions indicated on the label. Most often, concentrates are diluted in a 1:1 ratio, and the expected freezing temperature of the prepared coolant will be -32...-44°C.

Is it necessary to flush the engine cooling system before replacing antifreeze?

Before replacing the coolant, it is advisable to flush the cooling system, as well as the lubricants. However, for this you should use distilled water or fresh liquid, which you plan to fill in later.

As a last resort, you can use well or tap water after boiling it in an enamel bowl for 30-40 minutes. The old coolant is drained and the cooling system is filled with “treated” water. Then the engine is warmed up (until the thermostat opens) and allowed to run for 20-25 minutes. After draining, some of the water remains in the engine, therefore, despite the simplicity and cheapness of the method, it is preferable to flush the system with fresh coolant (although this will require additional financial costs). Dirt, corrosion products and scale can be effectively removed using special rinses. Some of them need to be added to the old coolant, others to the water filled in for flushing. It must be remembered that anti-corrosion additives in antifreeze can interact with scale, so when switching from water to a low-freezing liquid, flushing the cooling system is also necessary.

What to add when the coolant level drops

—Water or antifreeze?

If the vehicle's cooling system requires topping up, you should use distilled water, the same antifreeze that was previously poured into the engine, or G-12 Plus antifreeze.

Antifreeze class G-12 Plus - easily mixed with other antifreeze classes G-ll, G-I2. At the same time, the properties of the resulting antifreeze are completely preserved.

But, to engine failure. But if the transfer of heat from the engine to the radiator itself is impaired, no matter how you blow it, overheating cannot be avoided.

For normal heat transfer from hot engine parts to the liquid, reliable contact with the walls of the cylinders and combustion chamber is necessary. Rust, dirt, scale in the engine cooling channels (and they are very thin) hinder heat transfer: the liquid carries away less heat than required by the selected mode. In such cases, the temperature of the pistons, rings, cylinders, cylinder heads, etc. It grows dangerously, their thermal deformations intensify, and the wear of engine parts quickly progresses. The temperature sensor may not notice local overheating of individual parts - after all, it controls the heating of the fluid and the outer wall of the cylinder head!

When the coolant boils, heat transfer is also disrupted. Because The cylinder walls and combustion chamber are in contact with steam bubbles, and they practically do not cool. Such a defect leads to thermal deformation (“warping”) of large engine parts (primarily the aluminum cylinder head).

If the head is excessively deformed, its repair completely loses its meaning - the entire assembly is replaced with a new one.

In order not to deal with dirt and scale, you need not to skimp on coolant and change it on time. Moreover, you cannot use surrogates or water. And when buying a used car, it is better to flush the cooling system.

In addition to cases of blockage of the cooling channels, the culprit for overheating is a faulty thermostat with a loosely closing bypass valve (this valve ensures the movement of overheated liquid through a small circulation circle, without cooling in the radiator, and, accordingly, faster warming up of the engine to operating temperature). But if, after the engine has completely warmed up, the faulty valve does not open completely, a significant part of the liquid will continue to move in a small circle, and the engine begins to overheat,

Since the cooling system is sealed (excessive pressure is maintained in it), the coolant can heat up in it to 115-120 ° C without boiling. If the tightness of the system is violated (the expansion tank plug is leaking, cracks in the system pipes, etc.), the liquid begins to boil already at temperatures of about 90°C. Therefore, you need to carefully monitor the condition of the pipes and the functionality of the expansion tank plug valve.

When the liquid boils, the pump does not pump well foamed liquid with a large volume of bubbles, because its impeller is designed to work with dense liquid, not gas. In addition to reducing the intensity of liquid pumping, steam bubbles, collecting in the upper zones of the system, clog the cooling system. At a certain “critical” volume of bubbles, the pump pressure, already reduced, becomes insufficient to pump the liquid - and now it does not provide any circulation in the cooling system. What follows is a real disaster: the stopped liquid in contact with the hot walls begins

It boils throughout the entire volume of the cooling jacket, and this is a death sentence for the engine.

By following simple cooling system maintenance procedures, you can avoid all these troubles.

Replacement frequency, what antifreeze to fill

According to the regulations, the recommended maintenance for replacing the coolant is specified by the manufacturer to be performed once every 4 years or after 40,000 kilometers. As for subsequent replacements, you need to be guided by the information on the canister of the product being poured.

The best choice for filling as a new fluid would be to use the original General Motors Dex-Cool Longlife product. It is produced in the form of a concentrate and has the following articles and order codes: 93170402 (1 l.), 93742646 (2 l.), 93742647 (2 l.).

In addition to the original product, you can purchase its complete analogues, Havoline XLC or Coolstream Premium. The latter, by the way, went to a plant located near St. Petersburg and was used as the first fill.

You can go the other way and look for antifreezes that meet the approval that the automaker requires for use in Chevrolet Lanos. One of these is Kroon Oil Antifreeze SP 12. Many car enthusiasts highlight its quality properties, as well as its long service life.

Leaks and problems

Problems with the cooling system in Lanos are typical for most cars. From time to time it is necessary to change the thermostat and pump. Sometimes, over time, the expansion tank begins to leak.

Antifreeze leaks from the pipes occur due to their wear, as well as due to failed clamps. Leaks can also occur from excess pressure in the system, due to the failure of the bypass valve located in the expansion tank plug. Therefore, it is recommended to change the cover periodically.

Many Chevrolet Lanos owners think about the condition of the fluid in the cooling system, as well as when to change it. There is also the question of whether it is possible to carry out such work on our own.

What type of coolant is filled in the Chevrolet Lanos

First you need to decide what type of liquid to fill.

Based on the operating instructions for a Chevrolet Lanos car, you should fill it with a liquid based on ethylene glycol.

It is recommended to listen to the manufacturer’s recommendations and not to pour other liquids into the system, including water .

When to change

Already at 40,000 km the antifreeze will be similar to this.

But another important point is when to change the fluid in the system.

The vehicle manufacturer recommends carrying out such work after 40,000 kilometers or 4 years of operation of the car.

But these deposits were at the bottom.

Also, the liquid will require replacement if it has low density . An aerometer should be used for checking. When the liquid has a different color from its natural color (brown or black), this is also a sign that it will require replacement.

Coolant volume

Another important question is how much liquid should be poured into the system and, accordingly, how much to buy.

For each model, the amount of liquid may be different. For Chevrolet Lanos the volume will be 7 liters .

From personal experience, drivers have verified that it only costs 5 liters to buy a fluid change in Lanos. This will be quite enough.

This volume is enough for the reason that, due to the design features of the vehicle, it is impossible to completely drain all the liquid from it. If all drainage requirements are met, a certain amount of liquid will necessarily remain in the block.

Which antifreeze to choose?

Many people recommend HEPU antifreeze, but it is quite expensive and made in Germany.

Regarding the brand of liquid, there is no advice here. There are now a large number of them on the market, and therefore the choice is huge. The main thing is that it corresponds to what the manufacturer recommends. When purchasing, it is important to check quality certificates or buy goods from a trusted seller.

Many Chevrolet Lanos owners think about the condition of the fluid in the cooling system, as well as when to change it. There is also the question of whether it is possible to carry out such work on our own.

When completely replacing the coolant, Chevrolet Lanos owners recommend G12 antifreeze.

First you need to decide what type of liquid to fill.

Based on the operating instructions for a Chevrolet Lanos car, you should fill it with a liquid based on ethylene glycol.

It is recommended to listen to the manufacturer’s recommendations and not to add other liquids, including water, into the system.

Replacing antifreeze in a Chevrolet Lanos is an integral part of vehicle maintenance. With prolonged use of coolant, the engine may overheat, which will lead to unpredictable breakdown of the technical unit.

Antifreeze for Chevrolet Lanos needs to be changed approximately once every 40 thousand kilometers of the vehicle or once every 4 years (whichever comes first). At the end of this period, the coolant will lose its original properties, as a result of which it will not be able to perform the tasks assigned to it.

The volume of fluid required for replacement is 7 liters. The data is based on the vehicle's operating instructions. Many owners of a car of this brand claim that no more than 5 liters are required for replacement. The difference in volumes is explained by the design features of the vehicle, due to which it will not be possible to drain all the antifreeze.

Please note: in addition to purchasing antifreeze, you should purchase about 7 liters of water to flush the cooling system if there is sediment on the walls of the system.

Replacing antifreeze in a Chevrolet Lanos can be done with your own hands. To do this, you need to figure out what tools are needed for replacement, how to drain the antifreeze, flush the system and fill in new fluid.

I came to the service to replace the antifreeze. I took with me 10 liters of distilled water and 2 canisters of 5 kg of Sintec LUX-OEM G12 antifreeze.

The worker first drained everything that was and could drain through the radiator cap. They added water, started it, and drained it.

And so three more times. AT THIS TIME THERE WAS ANOTHER 4 LITERS OF WATER LEFT! I don’t know why they didn’t wash it all. The worker said that he considered this sufficient. Next, they blew out everything that could be blown out with a compressor.

The inside of the tank after washing was clean, without deposits.

Next, they poured in 5 liters of antifreeze, simultaneously squeezing the pipes and bleeding air out of them. Screwed on the tank cap, started the engine, and turned on the gas. The temperature rose to operating temperature, the thermostat opened. They turned it off and let it cool. After 10 minutes, they again drained the liquid from the system and blew it out with a compressor. Then they poured in a second 5 liters of antifreeze, simultaneously squeezing the air vent pipes. Thus, almost only antifreeze remained in the system.

Started the engine, the temperature was the same as before the replacement.

The antifreeze is now fresh and bright red.

That's all. Now the question is: 1) was washing with 6-7 liters of water and then another canister of antifreeze enough?

2) don’t you now need to remove the air from the system yourself? I mean, warm up the engine until the propellers turn on, turn it off, let it cool, slightly open the reservoir cap and let the engine run with the reservoir cap slightly open for 5-10 minutes to bleed the air and tighten the cap?

The coolant (coolant) of Daewoo Lanos must be replaced every 40,000 (km) mileage. If this is not done, then the antifreeze completely loses its properties. This moment entails the formation of corrosion in the cooling circuit, engine overheating and many other consequences.

It is worth noting that all coolants have pronounced carcinogenic properties. Ethylene glycol-based liquid is especially toxic. Its closest analogue is propylene glycol, it is less harmful to the human body, but costs much more than ethylene glycol.

It should be separately noted that when replacing the coolant, it is strictly forbidden to simply pour the “working off” onto open ground. Old antifreeze is disposed of by flushing it into the centralized sewerage system (does not apply to service stations, only to private craftsmen).

Let's start with the fact that this work belongs to the light category. Even a beginner who has only recently received a driver’s license can change service fluids in a Daewoo Lanos.

When replacing antifreeze, the technician will need:

1. A set of keys
2. Screwdriver Set
3. Pliers
4. Jack
5. Watering can
6. Container for draining "working off"
7. Distilled water (at least 20 l)

Experts strongly recommend using a half mask with a respirator when replacing antifreeze, which eliminates not only mechanical suspension, but also vapors of volatile liquids. Let me remind you that antifreeze (especially ethylene glycol) is a strong carcinogen that causes cancer.

Regarding the choice of antifreeze, it is best to take a concentrate, which must be diluted with distilled water in a 1:1 ratio. The fact is that when flushing the cooling system, up to 2 liters of washing water remain in the channels. It is impossible to completely drain all the liquid, due to the design features of Daewoo Lanos.

Concentrate dilution proportions: 3.5 liters of coolant concentrate and 1.5 liters of distilled water (2 liters of water are already in the cooling system).

• We drive the car into an area with an inspection hole and turn off the car.
• It is advisable to jack up the rear right side (as for removing a wheel) and place a stand on it.
• We look into the cabin and set the heater regulator to the MAX position so that the liquid drains from the stove too.

• Open the hood and unscrew the cap on the coolant expansion tank.

• We climb into the hole and remove the engine protection.

• We place a container under the plug to drain the antifreeze, unscrew the plug on the radiator (in the lower corner on the driver’s side) and carefully drain the entire contents of the cooling system. Some craftsmen do not remove the crankcase protection, but in this case, the “working off” may not drain neatly, past the container, splashing on the sides.

• We remove the coolant pipe from the throttle body fitting to drain the coolant more completely.

• Now it is necessary to clean the cooling system channels.
• We tighten the radiator cap.
• We look under the hood and remove the pipes on the expansion tank for antifreeze, unscrew the expansion tank mounting bolts (2 pieces). The inside of the tank needs to be rinsed thoroughly. Please note that it is highly advisable to drain the water after washing the tank into a centralized sewer system, and not into a flowerbed or garden.
• We put the tank in place and connect the pipes to it.

• Fill the expansion tank with distilled water (about 5 liters will fit). Please note that when water flows out of the throttle body pipe, you need to place it on the fitting and fix it, that is, put it in place, and add water to the MAX mark. We tighten the tank cap.

• We put the car on the handbrake, put the gear in neutral and start the car. We pull the throttle cable, putting a load on the engine. We wait until the radiator forced cooling fan starts working. His work will hint at the boiling of water in the system. We turn off the car. We wait about 1 hour for the liquid to cool and drain the water. It is also advisable to pour it into a centralized sewer.

• We fill the tank with distilled water again. We start the car again, but no longer pull the throttle cable. We wait 3-5 minutes and drain the water. We repeat this procedure 2-3 more times. That's it, we can assume that the engine cooling system has been cleaned.
• We dilute the coolant concentrate with distilled water. For 3.5 (l) of concentrate, use no more than 1.5 (l) of distilled water, since there is always about 2 (l) of liquid left in the system.
• We remove the stand from under the rear wheel, install the crankcase protection, and do a test drive.

Before you begin the replacement, you need to prepare for the procedure. You will need tools and other materials.

Required tools and materials:

• Pliers;
• Screwdriver;
• Capacity;
• 10 mm wrench;
• Jack;
• Watering can.

Step-by-step instructions for the process of replacing antifreeze in Lanos:

1. The fluid is replaced after the vehicle's power unit has cooled down. The car is placed on level ground.
2. Find the drain plug at the bottom of the radiator element. It needs to be unscrewed.
3. Unscrew the cap of the expansion tank.
4. Place a container with a capacity of at least 10 liters under the drain hole for draining.
5. To quickly fill the refrigerant, you will need to remove the fasteners from the throttle element.
6. There is no antifreeze drain plug on the cylinder block of the Chevrolet Lanos. It will not be possible to drain the liquid completely. For maximum drainage, you need to take a jack, place it under the rear right wheel and lift the vehicle. Thanks to this procedure, the maximum amount of coolant will be drained.
7. Is the drained fluid dark and dirty? It is advisable to flush the system.
8. To flush the system, you need to tighten the drain plug on the radiator, unscrew the filler and fill with distilled water.
9. Start the power unit for 5-10 minutes.
10. Drain the water in the same way as the coolant. Repeat the procedure. Flushing the system is completely completed until clean water flows out of the system. Attention: the expansion tank may be dirty. To clean it, you will need to dismantle it.
11. Fill with new fluid up to the MAX mark. To ensure that the liquid spreads correctly throughout the system and that air pockets do not form, it is necessary to squeeze the pipes during the filling period.
12. After filling the system with liquid, you need to start the engine. Let it run for a few minutes until the radiator comes on. Turn off the engine. Check the level of the substance. It (the level) should be near the maximum mark indicated on the tank. If necessary, add fluid to the required level.

The coolant replacement procedure is complete.

Step 1. Draining waste residues. Prepare a container for waste liquid. Lift the hood, the Lanos drain plug is located at the bottom of the radiator.

Replacing coolant on Lanos and the necessary tools

If your vehicle's coolant reservoir looks like this, then replacement is necessary.

After deciding on the quantity and brand of liquid, you should prepare the tools. Required:

Instructions and exact algorithm

1. Replacement is carried out only on a cold engine. The car must first be placed on a level surface. Next, there is a plug at the bottom of the radiator and it unscrews.

Place the car on a level surface and wait until the engine cools down.

The coolant drain plug is indicated by an arrow.

Be prepared to see such a "kaku".

We removed the pipe so that the antifreeze would drain faster.

If after draining the coolant you see such dirt, then flushing the cooling system is necessary.

Fill in new antifreeze.

We control the risks.

Replacing coolant (antifreeze) in a Daewoo Lanos car (Daewoo Lanos)

With the onset of the autumn-winter period, many motorists are wondering: what is the condition of the coolant ( antifreeze or antifreeze ) in their car, is it time to replace the coolant, what to pour into the engine cooling system - antifreeze or antifreeze and, of course, many Car enthusiasts are concerned with the question: is it possible to replace the coolant with your own hands? You will find answers to all these questions in this article. It will describe the process of replacing antifreeze in a Daewoo Lanos car . To begin with, we decide on the type of coolant. According to the automaker's instructions, antifreeze (ethylene glycol based) must be poured Daewoo Lanos . We follow the instructions and do not try to use antifreeze or, God forbid, water. Why shouldn't you use antifreeze?

conclusions

If after these procedures the liquid loses its original color over a short period of time, then it can be concluded that it was purchased of poor quality. In this case, it is recommended to change it to a new one as soon as possible after detecting loss of color.

The technical instructions for operating a Lanos car indicate that the frequency of replacing the coolant is 40 thousand km or every 2-3 years. What are the dangers of not following this recommendation? Antifreeze, like oil, tends to lose its characteristics. The result of a decrease in performance is manifested in the form of the formation of corrosive deposits in the system, overheating of the engine and failure of the cooling radiator and heater, pump and thermostat. How to replace antifreeze on Chevrolet, Daewoo and ZAZ Lanos is described in detail in the material.

How to find out what is in the cooling system of a car

Replacing antifreeze in a Chevrolet Lanos 1.5 is not a complicated procedure, but it is much more difficult to choose the appropriate coolant that will ensure efficient engine operation (meaning, it will ensure quick warming up of the engine in winter and cooling it in summer). Which coolant is best to fill into a car is described in detail in this material. Today we will learn how to determine what kind of coolant is poured into the cooling system of Lanos, Sense and Chance cars, how to determine the need for replacement, and also how to replace antifreeze with your own hands.

If you forgot or bought a car, but did not find out from the previous owner what type of refrigerant he used, then you can find out on your own. Two types of refrigerants are used as coolants - antifreeze and antifreeze. To find out what type of coolant is filled, you need to pay attention to the following factors:

1. Try it by touch.
   Antifreeze has no odor, unlike antifreeze, but has an oily consistency. Antifreeze does not have an oily film
2. Resistance to frost - for this it is not necessary to wait for the arrival of cold weather.
   Fill the bottle with some liquid from the expansion tank and place it in the freezer. If after 20-30 minutes the coolant does not freeze, then it is antifreeze. Freezing of the liquid indicates that the system is filled with antifreeze.
3. The incompatibility of antifreeze with water is a simple way to find out what is poured into the engine cooling system of Chevrolet and Daewoo Lanos.
   To do this, you need to collect liquid from the tank into a container and dilute it with water. Mixing of liquids indicates that it is antifreeze, and separation (antifreeze settles) indicates the use of antifreeze
4. Use a hydrometer - this is a special device for determining density.
   Antifreeze density ranges from 1.073 to 1.079 g/cm3

Using one of the above methods, you can understand what exactly is poured into the Lanos cooling system.

Antifreeze for Daewoo Lanos

If you are the owner of a Daewoo Lanos, then you should understand that the coolant must be based on ethylene glycol, so any antifreeze or water is out of the question. Let's first look at the reasons why it is necessary to replace antifreeze:

Low coolant density; antifreeze has changed its natural color, becoming brown, dark or discolored; Since the last antifreeze change, the car has driven 40,000 kilometers, or 4 years have passed since then.

To replace antifreeze in Daewoo Lanos, according to the instructions, 7 liters of liquid are required, but we can say with confidence that five is enough. This is due to the fact that the car does not have a drain plug on the block, so it is impossible to completely drain the antifreeze. If antifreeze has already been purchased, then it is enough to assemble the necessary set of tools and you can get to work.

For Lanos, as for any other passenger car, the cooling system uses antifreeze, which not only removes excess heat from the engine, but also acts as a lubricant for all elements of the ODS. When choosing antifreeze, it should be taken into account that liquids may differ by brand (different additives): regular antifreeze; hybrid: carboxylate; lobrid. If you need to mix coolants, you need to choose similar brands, not colors. Manufacturers can use a variety of colors; there are no clear regulations in this regard. It is not recommended to use water; it boils already at 100°C and does not have lubricating properties, and scale may form after boiling. Antifreeze is replaced in the following cases: its service life has come to an end; leaks due to damaged pipes or as a result of overheating; repair or replacement of engine cooling system elements. On average, depending on the brand, antifreeze should be changed every 3-5 years or with a mileage of 150 to 250 thousand km. Using the liquid longer is fraught with consequences; in hot weather it will boil, and in winter the risk of freezing increases. Do you understand that it’s time to change the antifreeze? can be done in several ways: using special test strips; by changes in color and consistency; by the presence of foreign impurities; using special instruments (refractometers). /expert_bq]

How to determine the need to replace the coolant on Lanos

Information on how often you need to change the coolant on your car is very useful. However, it is not always relevant, since few car owners remember when the last replacement was made. To determine whether it is time to change antifreeze on Lanos, Sense and Chance, you need to rely on some methods.

Today, manufacturers are producing a new generation of antifreeze, the service life of which has been increased to 200 thousand km. This resource is determined by the presence of anti-corrosion additives. It is not rational to buy such an expensive refrigerant for a budget car, so when using antifreeze, it should be changed every 3-4 years.

You can determine the need to replace antifreeze on Lanos by the state of the refrigerant. The liquid must be clean and free of dirt, rust and other deposits. If the condition of the fluid is not satisfactory, it should be replaced and the system flushed. It is recommended to change directly to the type of fluid that was poured into the system from the factory. You can find out the type of fluid in the technical documentation for the car. However, finding a similar brand of refrigerant can be problematic, so we use the most suitable type of coolant.

How to change coolant

Antifreeze should be replaced after the engine has completely cooled down. It is also important that the car is installed on a relatively level area.

How to drain

How to fill

1. After all previous operations have been completed, pour new coolant into the tank until its level reaches the MAX mark on the expansion tank. We start the engine and wait for the fan to work.
2. To better fill the system with liquid and to prevent air locks from forming, be sure to squeeze the radiator pipes with your hands while filling.
3. Turn off the engine. Check the antifreeze level in the tank.
4. If necessary, add coolant until it reaches the “MAX” mark.

How much antifreeze does the cooling system of Chevrolet and Daewoo Lanos hold?

Before you replace the coolant with Lanos 1.5, you will need to initially purchase the required amount of refrigerant. For each car model, the amount of coolant is different. The required amount of antifreeze is indicated directly in the technical documentation for the car.

The capacity of the cooling system for Lanos, Sense and Chance is 7 liters. This is exactly the amount of coolant that will need to be purchased in advance before replacing it. However, during the replacement process, you may encounter the fact that some of the liquid being poured will remain - approximately 1.5-2 liters. This is due to the fact that it is almost impossible to drain all the liquid from the system. That is why 5 liters of new antifreeze (3.5 liter concentrate) is enough, poured into the engine cooling system of Chevrolet, Daewoo and ZAZ Lanos.

What antifreeze to pour into the engine cooling system of Lanos, Sens and Chance

Today there are a large number of types of coolants on the market. Which type of coolant is best to choose depends on many factors. To decide which antifreeze to pour into the Lanos engine cooling system, you should familiarize yourself with this material, on the basis of which you can make the right decision.

Experts recommend pouring antifreeze into Lanos of the same brand that was originally filled from the factory. In this case, you won’t even need to flush the system first. If a different brand of antifreeze is selected (in most cases), then a system flushing procedure is carried out before replacement.

What should you put in a Daewoo Lanos car: antifreeze or antifreeze?

Imported antifreezes mainly comply with ASTM and SAE5 standards. They regulate the properties of concentrates and antifreezes based on their basis and operating conditions. For example, ethylene glycol coolants:

•ASTM D 3306 and ASTM D 4656 - for passenger cars and small trucks;

•ASTM D 4985 and ASTM D 5345 - for engines operating in severe conditions. Moreover, a special additive must first be added to these coolants.

In addition to general standards, many car manufacturers apply their own specifications, with additional requirements. For example, the General Motors USA standards are Antifreeze Concentrate GM 1899-M, GM 6038-M or the Volkswagen Group G standard system.

Such documents often prohibit the introduction of corrosion inhibitors containing nitrites, nitrates, amines, phosphates into antifreeze, and stipulate maximum permissible concentrations of silicates, borax and chlorides7.

Operation of antifreeze

Coolant service life

During operation, the coolant ages - the concentration of inhibitors in it gradually decreases, heat transfer decreases, the tendency to foam increases, and unprotected metals intensively corrode. The service life of antifreeze directly depends on its quality and mileage of the car.

Aging is especially intense when exhaust gases leak into the cooling system or air is sucked in. Therefore, you need to frequently check places of possible fluid leaks, as well as the condition and fastening of the hoses.

The period for replacing antifreeze is prescribed by the car plant or coolant manufacturer. But sometimes the liquid ages earlier, with:

•a jelly-like mass forms on the inside of the throat of the races.

There is no room here - it is better to fill in imported antifreeze - it will save money

What is needed to replace antifreeze on Chevrolet and Daewoo Lanos

Before carrying out work on replacing antifreeze and antifreeze on Lanos, you should make sure that you have the necessary tools. The replacement procedure is not difficult, and there is no need to go to a car service center to carry out the replacement. Even a beginner can cope with this task by first preparing the necessary equipment, materials and tools. To replace the refrigerant on Lanos, you should make sure you have the following tools:

1. Set of keys and screwdrivers
2. Pliers
3. Jack
4. A container for draining old fluid of at least 5 liters. Draining refrigerant into the ground is strictly prohibited, as this is harmful to the environment. After draining the liquid into the container, it should be disposed of. Antifreeze contains ethylene glycol, which contributes to the development of cancer.

The materials you will need are antifreeze or antifreeze in the required quantity. If the antifreeze is not diluted, then distilled water is purchased separately. To flush the system, you will need a can of special liquid (reagent), which is poured into the system, mixed with the old refrigerant.

Considering the fact that 1.5-2 liters of water remains in the system after draining, which is due to the design of the engine system, when using concentrate you will need to dilute it in the following amount:

• Mix 3.5 liters of concentrate with 1.5 liters of distilled water
• You cannot use ordinary water to dilute the concentrate, as it freezes at subzero temperatures.

When all the preparatory work has been completed, all that remains is to begin the relevant replacement work. First, let's look at how to flush the engine cooling system on Lanos.

How to pre-flush a car's cooling system

Before replacing antifreeze on Lanos, Sense and Chance, it is necessary to flush the system. This procedure is not at all mandatory, but it is recommended in the following situations:

• When the type of coolant changes, for example, if antifreeze has been added and it is planned to use antifreeze
• When changing the type of refrigerant, for example, if G11 antifreeze was previously filled, and it is planned to use G12 or G13
• If the refrigerant being drained is red in color and shows signs of blockages

The primary rinsing process involves performing the following manipulations:

1. For flushing, a special liquid is used - a reagent, which is poured into the expansion barrel. Before adding flushing fluid, you need to warm up the engine to operating temperature.
2. Add fluid and let the engine idle for at least 10-20 minutes.
3. In this case, you should turn on the heater in the car to maximum in order to flush the heater radiator

After the engine has been running for 10-15 minutes, you can turn it off and begin draining and replacing the refrigerant. How to replace antifreeze on Chevrolet and Daewoo Lanos, we will consider in detail below.

How to change the coolant?

Let's take a closer look at how to replace antifreeze in Lanos with your own hands.

Required Tools

To replace you will need the following tools:

• pliers;
• screwdriver;
• 10mm wrench, it is better to use a socket wrench;
• a bucket or old basin into which the waste liquid will be drained (a cut-off five-liter bottle will do);
• a jack to raise the front of the car;
• a watering can or funnel, with its help you will carefully pour in the new “Antifreeze” (the cut off top of the bottle will also work).

How to drain?

Changing a consumable begins with draining it:

1. It will not be possible to completely remove all the antifreeze from the system, but you should try to drain as much fluid as possible from the engine. To do this, the vehicle must be placed on a flat surface; it will be more convenient to drive it into a pit or overpass.
2. Find the refrigerant drain plug on the radiator; it is located on the left, in the lower corner, as shown in the photo. Place a prepared container under the plug to collect used antifreeze. Unscrew the lid.
3. After this, unscrew the filler cap located on the expansion tank.
4. The draining process will begin. To quickly drain consumables from the system, you need to remove the pipe from the fitting located on the throttle. This pipe is removed from the throttle assembly using pliers or a screwdriver.
5. You won’t be able to drain all the refrigerant, but you can try to minimize the remainder in the cooling system of the power unit. To do this, take a jack and use it to lift the rear right wheel.

Flushing

If the antifreeze has never been changed before or there are deposits in it, then the system must be flushed.

Otherwise, the dirt that remains in it will not allow the liquid to fully perform its functions. Water is used to flush the cooling system. Buy distilled water; tap water is not recommended. It contains substances and microorganisms that can lead to corrosion on metal elements of the system, for example, a radiator.

1. Flushing is performed by tightening the plug on the radiator device with cream. About five liters of distillate are poured into the expansion tank. Water flows until it begins to flow out of the previously disconnected throttle pipe. When this happens, the pipe is put in place and the plug on the expansion tank is tightened.
2. Now the car engine starts, it should run for 3-5 minutes.
3. After this time, the water is drained from the cooling system. Assess the color and condition of the drained liquid - it will contain sediments and deposits, the color is usually brown. If the drained water is dirty, the washing process is repeated two to three more times. Flushing is done until the water drained from the system is as clean as possible.
4. In practice, deposits also form in the cistern. Remove it using a 10mm wrench and rinse the container with clean water.

How to fill coolant correctly?

When draining and flushing are completed, new refrigerant is added. The drain plug is screwed in, the pipe from the throttle is installed in place. When pouring liquid, antifreeze must be added to the maximum mark on the tank body. To speed up this procedure, when filling, you should press the hoses of the radiator device with your hands from time to time. This will avoid the occurrence of air locks in the system. When the filling is completed, the power unit is started for a few minutes, then switched off. This is done to diagnose the refrigerant level in the expansion tank - it should decrease. If this happens, then the liquid is again added almost to the MAX mark.

Below is a detailed video instruction on how to independently replace the refrigerant in Lanos from the Garage TV channel.

Step-by-step description of how to replace antifreeze on Lanos Sense and Chance

The procedure for replacing coolant on Lanos is performed in the following sequence:

1. It is advisable to drive the car into the inspection hole
2. Jack up the rear right side of the vehicle to help ensure maximum fluid drainage.
3. Open the hood, and then unscrew the cap from the expansion tank
4. After this, you need to move to the inspection hole, and if there is engine protection, dismantle it. The protection is secured with 4-5 bolts depending on the design
5. Find the plug at the bottom of the cooling radiator and unscrew it, having previously prepared the container
6. To increase the intensity of draining liquid from the system, loosen the clamp and remove the pipe from the throttle assembly
7. The design of the engine block does not have a drain plug, which is a disadvantage on Lanos. There is such a traffic jam on Senses and Chances. The absence of a plug does not allow all the liquid to be drained, so there is still about 1.5 liters left in the system after the coolant stops flowing from the radiator drain hole
8. If dirty and contaminated liquid leaks from the system, then after draining, you need to repeat the flushing procedure using water. It is better to use distilled water, since if you fill it with regular water, you will not be able to drain it all, so there is a risk of freezing at low temperatures. Add a spoonful of citric acid (40 grams) to the poured water to increase the washing efficiency.
9. The principle of flushing is as follows: tighten the radiator cap, pour 5 liters of distilled water into the expansion tank, and lower the rear part from the jack, start the engine, letting it run for at least 10 minutes. Filling with water is carried out up to the MAX mark on the expansion tank
10. Repeat the system flushing procedure as many times as necessary until clear water begins to flow out of the system. Usually this is done at least 2-3 times
11. There is another way of washing. To do this, a hose with water is connected to the expansion tank, and a container is installed under the drain hole (you can attach a plug with a fitting onto which the hose is placed). Water opens and enters the tank, and the engine starts. After passing at least 10-15 liters of water through the system, all contaminants will be removed from it
12. If there is dirt in the expansion tank, it should be dismantled and washed. It is attached to the stand with two nuts. You must first loosen the clamps securing the suitable hoses. Two hoses are at the top and one at the bottom
13. When the system is flushed, you need to drain all the water and tighten the drain plug on the radiator. Antifreeze is poured, pre-mixed with distilled water.
14. It is necessary to fill the liquid up to the MAX mark. During the filling process, you need to press the pipes, which will allow air to be expelled from the system.
15. After filling the system, the engine starts and warms up to the temperature when the cooling fan turns on (about 92 degrees)
16. Check the level in the expansion tank and, if necessary, top up to the MAX mark

This completes the procedure for replacing the coolant on Lanos. As you can see, the procedure is not difficult and takes no more than 2 hours. After replacement, you can use a marker to write down the mileage on the odometer on the extender, so that next time you don’t have to calculate when to replace it.

The principle of replacing the coolant on SENS and Chance cars is almost identical, with the exception of a small difference - on SENS and Chance there is a drain plug on the engine block, which must be unscrewed together with the radiator cap.

Despite the presence of this plug, it is also impossible to drain all the liquid from the system, so all washing and filling steps are performed identically as on Lanos. In Sens and Chance, the radiator drain plug is located on the other side.

The video below shows how to flush the Lanos engine cooling system without unscrewing the radiator drain plug. This method is good because it will allow you to clean the system in the engine block using a flow method, reducing the time of the procedure.

Replacing Lanos antifreeze step by step

Step 1

. Draining of waste residues. Prepare a container for waste liquid. Lift the hood, the Lanos drain plug is located at the bottom of the radiator.

Unscrew the plug in a counterclockwise direction. It should look like this:

Carefully unscrew the expansion tank cap. Drain waste until the tank is completely empty.

Step 2

. Flushing the cooling system. Tighten the radiator drain plug. Pour in the first reagent. Pour distilled water in there to fill the container.

Then tighten the cap of the container and start the car. Warm up the engine, then drain the cleaning fluid again.

Fill in reagent number 2. Repeat the same procedures as when using the first reagent. After draining the contaminated substance, close the tank and fill it with distilled water. Start the engine again and then drain the fluid. To completely clean the system, repeat these manipulations 2-3 more times.

Step 3

. Filling with antifreeze. After cleaning, 3 liters of coolant are poured into the tank, and then distilled water is added.

After the tank cap is tightly closed, test run the engine. The antifreeze replacement is complete.

The liquid tank capacity is 6 liters and must be completely filled. Follow safety precautions. Do not add antifreeze while the engine is running, otherwise it will splash out. Heated antifreeze, if it gets on the skin, causes severe burns. The machine must be placed on a level surface; replacement should not be carried out near water sources or reservoirs.
