Replacement and maintenance of UAZ Patriot spark plugs


Spark plugs for UAZ Patriot


UAZ Patriot is a recognized leader among Russian SUVs.
Euro 4 engines (ZMZ-409) are excellent solutions for such machines. Motors that are actively used by automobile companies in Europe are now gaining popularity in the CIS countries. They work due to such an important element as candles. The factory equipment will work without problems until the mark on the odometer exceeds 20,000 km, but only under one condition - the fuel must be of high quality.
Otherwise, the part will deform quickly. Gasoline and diesel that meet the standard are very difficult to find. Almost all gas stations dilute the liquid with water and other compounds. It is difficult to provide excellent working conditions for spark plugs, and this is not the driver’s fault; as a result, they quickly fail.

new spark plugs


The topic of the article is spark plugs ZMZ 409, 405. After an article was written about individual ignition coils , people demanded to update the article about spark plugs of a new type. Let me remind you that, as a rule, “thick spark plugs” were installed on Euro-0 and Euro-2 engines with common ignition coils, with 21 spark plug keys. On Euro-3 engines and beyond, with individual ignition coils - “thin spark plugs”, for a 16 spark plug wrench.

High-quality gasoline is a guarantee of spark plug performance


There are many engine modifications for UAZ and VAZ. Manufacturers produce Euro 4 engines in different solutions. There is no standard manufacturing technology for the part, hence the lack of identical models is understandable. Each company improves its products as it sees fit. Don't get confused when the factory spark plugs wear out and it's time to buy new ones. When choosing a part, it would be good to have some information regarding the design of the engine and the parts on which its functioning directly depends. Competent advice from a salesperson in a store is good. However, who knows your car better than you? All UAZ Patriots are equipped with ZMZ-409 engines. The system is characterized by the following features:

  • presence of 4 cylinders;
  • operation on gasoline;
  • presence of microprocessor injection.

Recommendations are provided in product documents. The optimal type of fuel is Euro 4 gasoline. It is this that allows the mechanisms to operate for a long time. This is the best fuel for such engines, but not the only one. You can also fill the tank with other gasoline. It's all about quality. Other fuels not only cause spark plug failure, but also contribute to disruption of the entire fuel system. The consequences are engine wear.

What happens if you replace the gasoline you need with another brand of fuel? Changes are usually visible immediately:

  • the car began to gain speed more slowly;
  • candles began to get dirty and burn out faster;
  • A tapping sound uncharacteristic of normal operation appeared while accelerating.

Using gasoline appropriate for the ZMZ-409 engine is a key requirement that drivers must fulfill. Otherwise, regular replacements are inevitable.

System faults

The main reasons for coil failure are winding short-circuits or overheating. This may be due to several factors: • on the spark plugs, the gaps between the contacts exceed the permissible standards; • high-voltage wires with gaps are installed; • non-standard cables are used without distributed resistance that limits the current; • severe contamination, oiling or waterlogging. Malfunctions in the operation of coils, as a rule, appear after the designated resource has been exhausted after 150–200 thousand km or more than 7 years of intensive use. Malfunctions can be easily identified by the following signs: • “triple”—missing sparking in one or more cylinders; • “breakdown tracks” are clearly visible on the coil body during startup in the dark; • cracks or chips on the surface of the dielectric cover; • coil overheating; • burning on rubber tips of high-voltage cables. On vehicles equipped with ZMZ-409.10 engines, coil problems are detected by the display of Chek Enerine and the corresponding codes: 091–094, 231–234, 241–244, 0300–0304, 0351, 0352, 2301 or 2303. Checking error codes • Displaying codes 091-094: To check the functionality of the coil when 091-094 is displayed, you must turn off the ignition and then disconnect the cables of the failed device. After this, turn on the ignition, reset the codes and after 1-2 minutes check whether the errors are displayed. If they appear again, there is a problem in the wires or in the control unit. When 231–234 are displayed, it means there is a problem with the coil, possibly a short to the housing. • Codes 241–244 are displayed: When 241–244 is displayed, turn off the ignition and disconnect the cables of the corresponding coil. After turning on the ignition, reset the codes and check for errors after 1-2 minutes. The repeated appearance of 241–244 indicates a problem with the wires or control unit. The display of 231–234 indicates a short circuit to the coil body. Express check of the serviceability of the coils An express check of the serviceability of the coils is carried out without preliminary dismantling. Remove the tip from the spark plug and connect a working spark plug to it. Pressing its body against ground, start the engine. The appearance of sparks indicates that the coil is working properly.

Choosing spark plugs for the UAZ Patriot engine


The stability and stability of the engines depends on the condition of the devices. Their serviceability directly affects the power, fuel efficiency, and starting properties of the engine. It is very important not to make a mistake with the choice of parts for the ZMZ-409 and its modifications. Signs of quality products are a base made of iridium and platinum alloys. The use of these two materials allows us to produce reliable designs. Such candles are not cheap, however, they quickly pay for themselves. Minimum service life is 60,000 km. Another good option is plasma prechamber products. They have a long list of advantages:

  • improved self-cleaning process;
  • original design in terms of structure, which makes it possible not to adjust the gap over and over again;
  • long service life.

When choosing the required configuration, it is necessary to take into account not only the country of origin and material, but also pay attention to the shape of the thread, the gap, and the length of the model.

For UAZ Patriot, spark plugs are suitable that meet the following parameters:

  • Thread dimensions – M14×1.25. Length from 19 mm.
  • Availability of built-in resistor.
  • The spark gap is 0.7-0.85 mm.

A part with these dimensions is suitable for UAZ Patriot.

For ZMZ-409 engines, A 14 DVR spark plugs or their analogues are used. Why exactly are they quality spark plugs for UAZ Patriot? For a more complete understanding of the essence of the issue, a transcript of the product is presented to you.

  • A – diameter, thread pitch. In this case it means M 14×1.25. Hex key size. This design is easy to install to suit any parameters.
  • 14 is a capital number. It is an important parameter that determines the characteristics of the temperature regime of the candles.
  • D – thread length. In this case it reaches 19 mm.
  • B – protrusion of the thermal cone of the insulator. Responsible for accelerating the warm-up of the spark plug after starting the engine.
  • P – presence of a built-in resistor. It is needed to reduce the level of interference for radio equipment and the electric motor control unit.

Spark plug replacement procedure: recommendations

Installing a new spare part is a simple process if you do everything step by step. The procedure requires the removal of all 4 suppositories. To do this, you need to take the following steps:

  • Find the tip with the seal.
  • Remove the product using a spark plug wrench.
  • If damage or defects are found, replace the element.

When replacing a new part, you need to pay attention to carbon deposits on the working area. A black coating indicates that the engine was running on an over-rich mixture. Light soot indicates an over-digested mixture. The norm is a light brown tint. This plaque indicates normal engine operation.

If only one of the four elements is damaged, they should be replaced as a whole.

Choice

After the factory spark plugs on the UAZ Patriot wear out, they need to be replaced with new ones, but before changing them, you need to make a choice. Now there are a huge number of manufacturers, and design options, they can be:

therefore, the car owner may be confused at the sight of such a huge selection. It is recommended to consult with the seller before purchasing.

Before buying spark plugs for a UAZ Patriot, you need to figure out what engine is installed in the car. This SUV is equipped with a ZMZ-409 gasoline power unit with four cylinders and microprocessor injection. To achieve maximum results, it is recommended to fill in Euro-4 gasoline; the car works best with this fuel; filling fuel below this value is undesirable, as this can lead to negative consequences, for example:

  • They will become slower to gain momentum;
  • Candles will quickly become dirty and burn out;
  • When accelerating, the valves begin to knock.

Based on the installed engine that is fueled with Euro-4 gasoline, you can choose those spark plugs that are designed specifically for this type of engine. Iridium and platinum are considered more durable and expensive; their minimum service life is about 70,000 kilometers. It is also worth paying attention to plasma prechamber products as they have a number of positive properties, such as:

  • Good self-cleaning;
  • Long service life;
  • A non-standard device, their body acts as a side electrode.

When choosing, in addition to the manufacturer, you should pay attention to technical data such as: clearance, length and thread of the product. For engines installed on UAZ Patriot, spark plugs that have the following parameters are suitable:

  • Thread with a length of at least 19 mm, and M14x1.25;
  • Built-in resistor;
  • The gap in which a spark is formed is from 0.7 to 0.85 mm.

The product with such data is suitable for this type of engine. As a rule, A 14 DVR spark plugs or their equivalent are used.

Replacement

The replacement process is not complicated, and if everything is done sequentially, then there will be no problems with removing all four spark plugs.

To replace and install, do the following:

  • The seal with the tip is removed;
  • A spark plug wrench is taken and the spark plug is unscrewed from the cylinder;
  • The removed element is checked for damage and, if necessary, replaced with a new one.

During replacement, special attention should be paid to the shade of soot; black color indicates an over-enriched mixture; if the soot is light, this indicates an over-rich mixture. Light brown color indicates that the system is working properly.

Selection of spark plugs for the UAZ Patriot ZMZ 409 engine

From the factory, a UAZ Patriot with a 409 engine is equipped with Brisk dr17yc spark plugs; they can last 20,000 km without any problems, but only on the condition that the gasoline must be of high quality. Finding high-quality gasoline is now difficult, no matter what “branded” gas station it is, at almost any of them it is diluted with various additives or foreign liquids. If the spark plugs fail earlier than expected, it may not be your fault, but you will still have to change them.

Gasoline is important!

But, besides this, it is extremely important to fill in gasoline with the correct octane number - for ZMZ 409 this number is 92. If you use other gasoline, the spark plugs will burn out, and detonation may occur. Each type of gasoline is divided into classes, there are only four of them. In order to avoid having to search for spark plugs on your UAZ Patriot once again, always fill in 92 gasoline with class 4 or 5. Class 5 fuel has the lowest sulfur content - only 10 mg/kg.

Short-term driving on fuel with an octane rating higher or lower than recommended is allowed in cases where it is not possible to refuel with the required fuel. However, you will immediately feel the difference; the engine will lose power. If you drive like this all the time, the spark plugs will get dirty faster.

Device

Candles directly affect:

  • traction (power);
  • fuel efficiency;
  • stable engine starting, especially in the cold season.

As mentioned earlier, there are a lot of spark plugs on sale for the UAZ Patriot with the 409 engine, and it’s not immediately clear which ones to choose. After all, not all of them are of high quality. And here it’s not even about the brand, but about the design features. The fact is that there are several types of candles, they all differ in cost:

The best performance is achieved by spark plugs made from iridium and platinum alloys. They are not cheap, but they should last 60–70 thousand km. Among other things, the durability of the spark plug is affected by the shape of the electrode and their number. In this regard, the best option would be the so-called plasma-prechamber spark plugs, in which the role of the side electrode is performed directly by the body of the product, so there will be no need to adjust the gap.

Options

In order to choose the right spark plugs, you need to take into account a number of other parameters:

  • thread pitch and length;
  • gap between electrodes;
  • heat number;
  • total length of the product;
  • presence of a built-in resistor to suppress interference.

Therefore, for the UAZ Patriot you need to select spark plugs with the following parameters:

  • the thread must be M14x1.25 with a length of at least 19 mm, the product must have hexagon edges of 16 or 21 mm;
  • the gap to create a spark should vary 0.7-0.85 mm, in extreme cases a gap of up to 1 mm is allowed;
  • heat number 17;
  • there is a built-in resistor.

Examples

Here are specific models of spark plugs that are guaranteed to fit a UAZ Patriot with a ZMZ 409 engine: BRISK DR17YC (factory), AU17DVRM, NGK BKR5E, BOSCH PLATINUM PLUS FR7DPX, DENSO IRIDIUM IQ, NGK BCPR5ES, Bosch FR8DC+.

Judging by the reviews, AU17DVRM produced in Engels work no worse than BOSCH PLATINUM and DENSO IRIDIUM. And this despite the fact that their cost is about 70 rubles. a piece! But in terms of durability, they lose, their service life is 10–15 thousand. The quality of BRISK DR17YC is approximately at the same level. These are the best inexpensive models. They also praise the Bosch FR8DC+, which is produced in Engels, as well as the AU17DVRM.

But DENSO IRIDIUM IQ, oddly enough, is not liked by everyone. Judging by the reviews, after 3000 rpm. the engine does not move, it is “stupid”, although the traction at the bottom and idling are very good. BOSCH PLATINUM also has a controversial reputation among Patriot owners; there are complaints about unstable idling and difficulty starting the engine after a certain mileage. There are no complaints about the briscoes and njk.

Spark plugs ZMZ 409, 405, installation

I am a follower of the Italian motor school, but the operators and mechanics are best from the Germans. Almost all German engine manuals say that for installing glow plugs for diesel engines and spark plugs for gasoline engines, it is necessary to use special thermal pastes. And this MUST be done when the cylinder head is made of aluminum. There are three types of pastes. Copper, aluminum and ceramic. I didn’t waste my time and have been using ceramic paste for many years now. The upper limit of the temperature at which it cokes is 1400 degrees. It is more likely that molten aluminum will drip from the cylinder head than a spark plug will burn in its place. The paste is not cheap, but one tube lasts for a very, very long time, for several dozen replacements of candles.

Recommendations for replacement

Installing a fresh spare part in this case is a fairly simple process if you do everything sequentially according to the instructions. Unfortunately, if one spark plug “flies”, it is strongly recommended to replace all the others too, so that the 409 engine of your UAZ Patriot works evenly and does not spoil the Euro 4 exhaust system. So what needs to be done:

  • dismantle the tip with the seal that is connected to the ignition module;
  • carefully, without jerking, using a spark plug wrench, unscrew the product until it is completely removed from the cylinder;
  • If the product shows any traces of damage (chips, cracks), breakdown of the insulator and other defects, such an element should be replaced.

Periodically, for example, once every 20 thousand km, check the spark plugs for looseness. During long-term use, they can “stick”, then unscrewing them without damaging the thread will be very problematic.

During a visual inspection, be sure to pay attention to the presence or absence of carbon deposits in the working area of ​​the product. You can tell a lot about how the engine was performing based on the color of the plaque. If the coating is black, then this indicates an over-enriched mixture in the cylinder (or “burning” of oil); a white tint, on the contrary, indicates a lean mixture. Red carbon deposits are a sign of poor fuel (with additives). A light light brown soot is considered normal, which means the engine is working as it should.
