How is antifreeze replaced with antifreeze?
To perform this procedure you will need: the antifreeze itself, flushing fluid, water for flushing the system and a container into which the antifreeze will be drained.
Guys, who switched from antifreeze to green antifreeze? Engine 406
Comments 46
at least switch to gray-burgmaline, everything is ok, even Mona without rinsing is not critical
I filled it with orange Motul antifreeze, pre-rinsed it with distilled water and rinsed, the flight was excellent.
I decided to switch from gasoline to gasoline. Has anyone tried it? I used to fill up with 92nd gasoline at Lukoil, I want to buy 92nd gasoline-petrolium at BP. Who will say for/against?
We have a leaflet on antifreeze in our store. It says: green is for aluminum radiators, and red is for copper and brass. How true this recording is, I don’t know)
Antifreeze is a brand. Antifreeze - anti-freeze (from English)
Different colors cannot be mixed! That's why they paint it so they don't interfere. When purchasing, choose one marked G-12. The boiling point is higher than that of G-11. the best in quality: red and green,
I've been pouring red antifreeze for 6-7 years already, the flight is excellent, our pipes have been wanting for 3 seasons. Sable 405 is green!
The question had to be posed differently - imported or domestic, and which brand of imported product had proven itself best. we must run away from ours, fake and self-made
So, once again, I’m writing again! Antifreeze is a Russian antifreeze, invented by the Russians, hence the quality and composition, etc., etc. Antifreeze and antifreeze are the same thing, only antifreeze is of higher quality and has better properties. I worked in a car service center, disassembled engines, I know and I saw everything! What else is unclear?
yes no, the water is still of better quality
And in general, I personally drive well on water economically, and even if it leaks, there is no harm to nature or cost, I poured a couple of liters from the pond and then pulled away nicely, but I sensed that the end of the engine was coming, I said to the car, goodbye
Finally finally
So which is better?
Fill up with antifreeze! awesome thing! When you change the pipes, don't forget to look inside.
Don't write nonsense if you don't understand.
I'm not rummaging? =) ride on your bucket and keep quiet
Antifreeze got into the engine: what are the consequences for the power unit
Let's start with the fact that antifreeze or antifreeze is a mixture of concentrate and distilled water. It is quite obvious that the entry of such liquid into the lubrication system and mixing with engine oil significantly worsens the properties of the lubricant.
Let us note that driving on such oil is quite capable of leading to rapid wear and overhaul of the internal combustion engine. If for old engines “overhaul” is a predictable and quite expected procedure, then the need to completely repair a relatively new engine may come as a complete surprise to the driver.
So, if antifreeze gets into the engine, while the unit continues to be operated in normal mode, then a knocking noise may appear in such an engine, and very quickly. Usually the crankshaft and camshaft bearings start knocking. Let's look at why this happens.
So, if oil mixed with antifreeze begins to circulate through the channels of the lubrication system, the first to suffer are the loaded plain bearings, better known as liners. More precisely, we are talking about the crankshaft and camshaft liners. Scores form on the surface of the liners, resulting in a knocking sound.
- After disassembling engines with such damage, you can see that the friction layer on the liners is literally erased, and the metal surface is covered with scratches and burrs. The smooth and shiny surface of the liner turns from the usual gray color to brown, covered with stains and scratches. The logical question is why this happened.
If you examine the surface of the damaged liners at high magnification (for example, under an electron microscope), very small white balls become visible. The size of the beads, on average, is only about 20-35 microns. These ball particles literally “eat” into the metal on the surface of the liners.
It becomes clear that these small particles, like an abrasive, erased the friction layer and formed scoring marks. Now let's figure out where they came from and what their structure is. Based on the results of chemical analysis, experts determine that the particles contain phosphorus, sulfur, calcium and a number of other chemical elements.
The main thing is that these particles are harder in comparison with the friction layer and the material itself for making sliding bearings. What is especially interesting is that these solid particles were formed from additives and additives that are found in the motor oil itself. Moreover, the formation of particles occurs precisely when engine oil additives are mixed with antifreeze/antifreeze, after which this mixture is heated.
Naturally, during operation of the internal combustion engine, the power unit gets very hot. Also, any processes inside the motor occur quite quickly. It turns out that if antifreeze gets into the oil, then when the engine is running, the crankshaft rotates, the speed of movement of other parts and components is high. This means that the mixture of oil and coolant is actively mixed, turning into an emulsion.

How often to change the timing belt on a car: what you need...
Let us remember once again that the coolant contains a large percentage of water. So, engine oil additives dissolve in water much better than in oil. The result is a high concentration of dissolved additives, even if a little antifreeze gets into the lubricant.
- Also, do not forget about the significant heating of the engine. High temperature significantly speeds up chemical reactions, mixing processes, etc. It turns out that after a short period of time after antifreeze enters the engine, strong phosphorus compounds of zinc and calcium are formed in the resulting mixture of engine oil, water and antifreeze concentrate.
We also recommend reading the article about why antifreeze or antifreeze gets into the engine cylinders. From this article you will learn about the main causes of the malfunction, as well as available methods for repairing the specified engine problem.
Now let’s imagine that such a mixture hits the heated surface of the liner. It is quite obvious that the water will quickly evaporate, leaving a small solid ball. This ball, like a grain of sand, forms scuffs and other defects on the smooth surface of mating parts.
Considering that a lot of such particles appear during the operation of the internal combustion engine and they actively circulate throughout the engine along with the oil, the results are not difficult to predict. The wear of surfaces increases significantly and accelerates; after a short period of time, the engine knocks.
Characteristics of liquids
So let's start with the definition. What is antifreeze? This is a coolant developed by Soviet scientists in the 70s. It was this that was used for the first Zhiguli cars. Subsequently, the coolant began to be used on the VAZ-2110. The car rarely needed to replace antifreeze - only once every two years. But antifreeze has an even longer lifespan. Although the composition of both liquids is the same. They are based on ethylene glycol. Moreover, the coolant is not initially painted in any color. Subsequently, the manufacturer adds the appropriate additives:
- Anti-foam. To prevent air from forming in the system and reducing heat dissipation.
- Anti-corrosion. Over time, system components may rust. Dirt particles clog small channels and prevent normal fluid circulation. These additives are also called corrosion inhibitors.
The liquid also has an anti-scale additive.
Composition [edit | edit code ]
One of the most common (and most effective as a coolant) coolant is ordinary water, especially non-scaling soft, distilled or deionized water. The advantages of water as a coolant include, inter alia, high specific heat capacity, low viscosity, high fluidity, availability and low price. However, water is corrosive to many metals (more precisely, it is not water itself that is corrosive, but a weak electrolyte formed due to the content of impurities in it, which provokes electrochemical corrosion), and also has the property of freezing at negative temperatures with the formation a solid ice monolith, which, due to the increase in volume when freezing, can seriously damage the engine water cooling jacket and radiators. Therefore, at present, as a rule, special coolants are used, the basis of which is the same water, but with functional additives (additives) that increase its performance characteristics.
Coolants (coolants) are divided into two large categories - summer coolants
and
winter (low-freeze) coolants
, also known as
antifreeze
. Currently, the performance qualities of antifreeze have improved to such an extent that in countries with temperate and cold climates they are often used for year-round operation of vehicles.
Why should you switch to antifreeze?
An imported product has many advantages over a domestic one:
- High efficiency of use. Coolant produced in Russia forms a protective layer on the metal walls. On the one hand, this is a plus. But on the other hand, the thickness of this surface can reach 0.6 millimeters, which significantly impairs heat dissipation. Thus, antifreeze has low heat transfer, which increases the risk of engine overheating. For antifreeze, this parameter is 0.0006 millimeters without loss of characteristics.
- Long lifespan. It is recommended to change antifreeze every 2 years or 60 thousand kilometers (whichever comes first). Antifreeze is designed for 5 years of operation or 150 thousand kilometers.
- Full set of additives. Antifreeze has all modern additives that provide maximum heat removal and prevent the formation of corrosion. These additives are based on inorganic acids (borates, nitrites, phosphates). Antifreeze uses silicates, which quickly lose their properties during operation.
- Radiator protection. When replacing antifreeze on a VAZ-2110 car with 16 valves, it is worth considering what material the heat exchanger was made of. Radiators can be aluminum or copper. The main disadvantage of antifreeze is that it does not have additives that can protect aluminum heat exchangers at temperatures of 100 degrees and above. Antifreeze is more loyal to such radiators.
- Resistance to high and low temperatures. Antifreeze freezes at -35 and boils at +105 degrees. Antifreeze has more advanced characteristics. So, the concentrate freezes at -45 and boils at +135. Moreover, it can be diluted with distilled water with virtually no loss of these characteristics. Antifreeze, when diluted, is no longer suitable for use in winter, since it can freeze already at -15 degrees, which is fraught with consequences.
Antifreeze and water
No less often, people wonder whether adding ordinary water to antifreeze is acceptable. The answer primarily depends on the form in which you bought the antifreeze. There are concentrated liquids, dilution of which is mandatory. The main thing is to follow the instructions. Particular attention needs to be paid to 2 subtleties:
- dilution should be carried out only with distilled water. Tap water is too hard and leads to precipitation; bottled drinking water is a little better, but still contains salts that the body needs, but are absolutely unnecessary in the cooling system;
- The proportions specified by the manufacturer must be strictly observed. Otherwise, the antifreeze will not perform its tasks as planned.
Now consider the option in which you find that the coolant level is too low and there is no reserve. There will be no particular problem in replenishing water, especially if you again use distillate in the summer. However, this action is not considered approved by many experts. Firstly, the liquid's ability to freeze will increase and its ability to cool will decrease. Secondly, when antifreeze additives pass through the insides of the system, they cover them with an anti-corrosion film.
The water added to the tank will slowly wash away the protection. And if you forget about the low concentration of antifreeze for a long time, the cooling system will begin to rust. Thirdly, if you performed such actions in winter and left the car with liquid antifreeze overnight in the cold, prepare for serious damage. Antifreeze, even if the temperature drops below critical, does not expand when freezing, the radiator does not freeze, and when the engine starts, it returns to its original state. Water can simply rupture the hoses and pipes if it is in them.
So let the question of whether it is possible to mix and dilute antifreeze with water remain purely hypothetical for you, and the situation in which you will have to translate it into practice will never arise. Antifreezes are not so expensive that you would risk the health of your car for the sake of a little savings.
Coolant
(coolant) is a liquid that plays the role of a coolant in the cooling system of an internal combustion engine and other machines. Modern coolant also performs other functions, including protecting the cooling system from corrosion processes and scale, rupture due to expansion during freezing and heating, the liquid itself, and so on.
Let's get started
First you need to place the machine on a flat surface. It is advisable that this be an inspection hole (if there is none, we take a jack). We need the latter in order to get to the fluid drain bolt. It is located in the cylinder block, near the plug. To unscrew it, use a ratchet with a 13mm head.
Helpful advice
When replacing antifreeze on a VAZ-2110 car, it is worth inspecting the condition of the pipes and hoses that go to the radiator and expansion tank. Characteristic signs of wear are:
If the pipe is cracked and hard to the touch, then it needs to be replaced. The clamps are also changed. They can be bought at any hardware store. The hoses themselves that go to the tank must be reinforced, as in the photo below.
