When to change spark plugs on a VAZ 2114. How often do you need to change spark plugs on a VAZ. Signs that it's time to replace spark plugs

The spark plug is an important element power unit car VAZ 2114. The ease of starting the engine depends on it internal combustion and further stable work. Therefore, it is important to take a responsible approach to choosing an ignition element.

Which spark plugs are better to choose for VAZ 2114?

Today there are a large number of companies on the market that specialize in making candles.

Manufacturers ignition elements that have proven themselves high quality and reliability of products:

• Finwhale;
• Champion;
• Brisk Premium;
• Bosch Platinum;
• DENSO.

Materials used for making candles: iridium, platinum, gold, palladium. A thin electrode with a diameter of 0.4-0.8 mm will produce the best spark.

Spark plug manufacturers

• Brinsk candles- high demand among car owners. A gap of 1.1 mm ensures a decent result in the functioning of the element;
• Denso- of Japanese origin. Quality and reliability are the basis of the company’s development. Ideal for VAZ 2114;
• NJK spark plugs is one of the most popular companies in the world. This type of auto parts successfully copes with the load even after 35 thousand kilometers. Suitable for VAZ 2114 car.

Now you can start replacing the spark plugs on the VAZ 2114.

Replacement process

Before replacing, you need to prepare: study safety precautions, select the necessary tools and materials.

Safety rules when replacing spark plugs:

1. Carry out the replacement procedure when the engine temperature drops below 30-40 degrees Celsius. Thanks to this recommendation, you can prevent the occurrence of burns on the skin.
2. Disconnect the on-board network. To do this, disconnect the negative terminal of the battery.
3. Wear gloves. They will help protect your hands from minor injuries.

Required tools and materials:

• Candle key;
• Compressed air cylinder;
• Brush for removing dirt;
• New ignition elements;
• Gloves.

Step by step procedure for replacing spark plugs:

1. Stop the operation of the power unit. Wait until it cools down to an acceptable operating temperature.
2. Lift the hood lid. Using a special design, fix it in the open position.
3. Grasp the rubber caps of the high-voltage wires and carefully pull them out of their installation locations.
4. Clean the surface from dirt using a brush.
5. Unscrew the ignition element using the key.
6. Carry out similar actions with the remaining candles.
7. Check the new spark supply element. Measure the gap between the electrodes.
8. Tighten the consumable by hand. Complete an action using a tool.
9. Connect high voltage wires.

Note: The main mistake of a novice car owner is to confuse the wires. You can't do this. High-voltage wiring is connected according to the markings in strict sequence for each cylinder.

After replacing the spark plugs, an unpleasant surprise may await the car owner. The engine speed may “float”, the engine jerks. Reason: perhaps a novice car owner purchased a low-quality ignition part. Defective goods must be returned.

It is easy to find out which ignition element is not working. To do this, the high-voltage wires are disconnected one by one. If the engine sound remains the same, the part is faulty and must be replaced.

Signs of faulty spark plugs

Signs of faulty spark plugs:

• Reduced power of the power unit and increased fuel consumption;
• Wave-like acceleration when sharply pressing the gas pedal;
• Stopping the power unit at high speeds;
• Prolonged cranking of the starter when starting the power unit;
• Triple.

Some symptoms may appear under special operating conditions. For example, when warming up the engine at sub-zero temperatures. However, this still indicates that the ignition element is faulty.

In order to replace spark plugs on VAZ cars, you should open the hood and install a support; by the way, not all VAZ car models are equipped with a support. Latest models Domestic cars have a plastic casing on the top of the engine that covers part of the engine. Remove it by unscrewing the mounting screws that secure it to the motor.

How to properly remove the high-voltage wire from the spark plug on a VAZ-2114

Let's move on, carefully remove the wire high voltage from the spark plug of cylinder 1 and place it on the cylinder head. It is necessary to remove high-voltage wires by holding them by the protective cap, and in no case by the wire itself, since in this case the contact between the wire and the cap can be broken, after which the armor wires will have to be replaced.

After this, it is necessary to mechanically clean carbon deposits and accumulated dirt from the sockets in which the spark plugs are installed. This must be done so that when replacing the spark plugs, the debris that has collected around them does not end up in the combustion chamber. Trying to wash off dirt is pointless and unreasonable, since all of it will somehow go inside the engine, which sooner or later will give results and cause damage to the piston group of your car.

Replacing spark plugs on a VAZ 2114

The next step is to unscrew the spark plug using a spark plug wrench, usually a 16 or 21 socket wrench, depending on what spark plugs are installed on your car. Spark plugs are unscrewed only when the engine is stopped and cooled; if this rule is violated, there is a possibility of getting burned and damaging the threads. If even after the spark plug is “torn off” it continues to unscrew tightly, there is no need to rush, make a couple of turns in the opposite direction and try to carefully unscrew it again. This must be done so as not to damage the threads in the cylinder head under any circumstances. If the spark plug is difficult and tight to unscrew, this may be due to the fact that a large amount of soot has accumulated on its walls or rod.

So, when the spark plug is unscrewed, you can install a new, pre-prepared spark plug. Install and tighten it until your fingers begin to slip, then arm yourself with a spark plug wrench and tighten it, being vigilant and careful not to accidentally strip the thread. Excessive tightening of the spark plugs is fraught with damaged threads in the cylinder head, as well as subsequent problems with replacing spark plugs.

The final stage. After the spark plugs are screwed in, you can put the high-voltage wires in place, and then install the plastic casing in place. Tighten it and try to start the engine. The engine should start immediately, and its operation should be stable and smooth.

All modern spark plugs, regardless of which company they are manufactured by or what features they have (for example, spark plugs with platinum elements), have a completely identical device.

They include components:

• contact nut for high voltage wires;
• insulator (heat-resistant ceramic);
• a faceted metal insert on the insulator, used for unscrewing the spark plug with a key;
• sealing ring;
• lateral contact;
• central contact.

There should always be a working gap between the last two elements (for injectors - about 1 mm) - in this gap a high-voltage spark will jump, igniting the working mixture in the cylinder (a separate spark plug is installed for each engine cylinder).

As for the period after which it is necessary to replace spark plugs on a VAZ 2114, it is: about 10 thousand km for simple budget-level spark plugs, about 15-25 thousand km for simple spark plugs from “branded” manufacturers, about 70- 100 thousand km for platinum/iridium spark plugs.

Signs that it's time to replace spark plugs

The above figures are approximate and should not be strictly adhered to. Sometimes even a simple candle can last longer than its allotted time, but a “branded” one may turn out to be of poor quality and quickly fail.

Incorrect “minor repairs” of flooded spark plugs by calcination or cleaning using coarse sandpaper also greatly reduce the service life.

Taking all this into account, replacing spark plugs with new ones should be done not according to some digital indicators, but guided by the following signs of their wear:

• • the color of the electrodes is different from brown and does not change after cleaning (white color indicates overheating, black/dark brown indicates problems with fuel combustion);
  • there is practically unremovable plaque/carbon deposits on the electrodes;

• if the metal shell of the insulator is painted a bright straw/golden color, then this brand of spark plugs is not suitable for this engine;
• abundant traces of oil on the spark plug and in the well, reappearing after cleaning it;
• chips of the ceramic shell of the insulator or damage to the metal lining.

If at least one (and even more so several) of the above signs are found on the spark plug, then it should be replaced as quickly as possible. In order to do this, you will need a new spark plug and a VAZ 2114 spark plug key (we’ll tell you what kind of key this is below).

How to replace spark plugs?

Before considering the question of how to change the spark plugs of a VAZ 2114, you should first talk about how this can be done? The answer here will be very simple - a spark plug wrench.

They are available in a variety of shapes, lengths and sizes of the working part. The most important thing to consider when purchasing this tool is the size. spark plug key VAZ 2114. It should be exactly 21 mm, no more, no less. All other characteristics, for example length, are not so important.

We can only say that many experienced car enthusiasts and car service workers advise not to save money and to purchase a more expensive key with a universal joint and a handle. It is much more convenient to use than a regular tubular wrench with holes for a wrench or screwdriver.

In addition to the spark plug wrench, you will also need a soft steel brush and a compressor (or a small can of compressed air).

The replacement procedure is performed in the following order (only on a completely cooled engine):

1. Open the hood and remove the engine cover (if equipped).
2. Remove the high voltage wires from the spark plugs.
3. Clean both the spark plugs themselves and the surface around them with a soft brush and compressed air (so that when unscrewing, dirt does not fall into the spark plug wells).
4. Use a spark plug wrench to unscrew the spark plugs (it’s best to just move them with a wrench and then unscrew them by hand - this will help avoid damaging the internal threads in the sockets).
5. Take new spark plugs and check their clearance (it should be about 1 mm).
6. Insert new spark plugs into place and tighten (at first - also by hand, with a key - only at the very end).
7. Place the high-voltage wires onto the contact nut of the spark plugs.
8. Put on the cover (if equipped) and close the hood.

The spark plugs should be replaced with new ones all at the same time. You should absolutely not replace only one or two spark plugs, even if the remaining ones seem to be “fully functional”.

In addition to the above rules for replacing spark plugs, several more important recommendations should be mentioned. So, we have already told you what kind of spark plug wrench is needed for the VAZ 2114, but it’s worth adding that a torque wrench would still be ideal. It is worth tightening the spark plugs using it with a force of up to 20 N/m - this is the optimal force that securely holds the spark plugs in the socket and does not damage the threads.

The second tip is to check the spark plugs for manufacturing defects. So, if after installing a new kit the engine runs poorly and with extraneous noise, then one of the spark plugs is faulty. You can find out which one you have by disconnecting the armor wires one by one while the engine is running, and then connecting them back. During this procedure, the sound of the engine will change when the good spark plugs are disconnected, and will remain unchanged only when the wire from the defective spark plug is disconnected.

The question of why so much attention is paid to ignition devices can be answered as follows. They belong to one internal combustion engine and ensure its stable and economical operation. You can perfectly adjust the thermal gap, fill in the highest quality gasoline, but all it takes is one poorly functioning one, and everything done will be in vain.

Device:

1. Contact nut for high voltage wires;
2. Spark plug insulator with fins;
3. Medium electrode;
4. Ceramic insulating layer;
5. Metal part of the insulator;
6. Radio interference suppression resistor;
7. Metal ring for sealing;
8. Washer for heat removal;
9. Central electrode;
10. Conical thermal insulator;
11. Candle workspace;
12. Side electrode;

The letters indicate the operational dimensions: d – thread diameter; h – gap for spark gap; L – length of the working part; l - thread length; S – key size.

All structural elements of devices are important in their own way, but the leading role belongs to the central electrodes. Therefore, they require special attention to themselves. Candles must have the following properties:

• Resistant to high temperatures;
• Good thermal conductivity;
• Plastic;
• Resistant to corrosion and erosion.

Therefore, to implement all these requirements, nickel alloys with various additives are used in manufacturing. There are ignition devices in which the electrode is coated with platinum. The main purpose of spark plugs is to ignite the air-fuel mixture at the end of the compression stroke.

ABOUT SPARK PLUG LIFE

The service life of spark plugs varies, depending on the manufacturers and their operating conditions.

Maybe equal to 10 thousand kilometers to several tens of thousands. Inexpensive products last approximately 10,000 km, and branded items last 50-70 thousand km. The duration of their operation largely depends on the condition of the engine piston group and the quality of the gasoline used. Wear of engine parts and poor gasoline sharply reduce service life.

ABOUT SIGNS OF PROBLEM

Many drivers, especially beginners, often have a question about how to understand that it is time to change the spark plug. To do this, when servicing the engine, you need to remove the spark plugs and examine them carefully. By the appearance of their working part, one can judge their performance.

1. The working part is brown, which indicates its good condition;
2. Available information about engine wear;
3. A chip in the central electrode insulation indicates the need to replace it;
4. The use of bad fuel will be indicated by deposits on the working part of the device;
5. The white insulator tells the driver that it is overheating;
6. A golden color indicates that the spark plug is not suitable for the engine;
7. Careless handling can lead to mechanical damage.

WHAT TO DO IF IT'S FLOODED?

Every car owner should know what to do when the spark plugs are flooded. Most often, motorists encounter this problem when operating vehicle in the cold season. In such cases, purging the motor will help. To do this you need to have with you:

• Candle key. Let me dwell on this in more detail. There are many of them in retail chains; any customer request can be satisfied. You can choose the simplest tubular one, a little over 80 rubles. Or buy expensive keys with cardan shafts, at a price of 300 rubles apiece. Good feedback receive models such as a key with a T-shaped handle FIT 63745, keys with cardan shafts models FIT 63747, VIRA 511045, or the following.AIRLINE AK-S-01;
• Spark plugs, preferably new ones;
• Charged battery.

1. Remove the protective casing on the engine (if equipped);
2. Disconnect from ignition devices;
3. Turn them out of the cylinder head;
4. Disconnect the wires from the ignition unit;
5. Press the gas pedal to the limit and about 7-10 seconds;
6. Now you can put the candles;
7. Connect high voltage wires. Each wire fits a specific spark plug, try not to confuse them;
8. The connector from the ignition unit is put in place.

Now you can try to start the engine. Some drivers warm up “flooded spark plugs” using accessible methods.

REPLACING CANDLES

If malfunctions of these devices are detected, the spark plugs must be replaced. To the question about the possibility of carrying out, there is only one answer, it is impossible. During maintenance, they are cleaned, the spark gap is adjusted, but not repaired. Better yet, let's talk about how candles are replaced with vases. This operation will again require a spark plug wrench. made simply and easily:

1. Remove high-voltage wires;
2. They turn them out of their nests with a candle wrench;
3. Screw in a new set, having previously adjusted the gap between the electrodes. For carburetor engines it should be 0.7-0.85 mm, and for an injector it is 1.00-1.13 mm;
4. High-voltage wires are put in place.

HOW TO CHOOSE GOOD CANDLES FOR VAZ 2114

You can find out which spark plugs are better in car magazines, the Internet and other sources, and the frequency of replacing these devices should be equal to 20,000 km. In winter, they are changed even more often, every 10,000 km. Automotive publications recommend using brands from global manufacturers such as “NGK”, “Finwhale”, “Champion”, “Brisk Premium”, “Bosch Platin”. Comparative tests have shown their superiority over the A17DFMRV produced by the plant in Russia.

2114 and VAZ 2115 are an important element of the ignition system, on which the successful start of the internal combustion engine depends. The article discusses cases when it is necessary to change spark plugs (SZ), which spark plugs to install, and also provides instructions for replacing them on VAZ 2114 and 2115.

[Hide]

In what cases is it necessary to replace spark plugs?

Replacement of SZ with VAZ 2115 and VAZ 214 is carried out every 30,000 thousand kilometers. If you do not change the SZ in time and continue to operate the car, then the wear of the electrodes sharply increases, this entails a drop in the car’s power and excessive fuel consumption. The condition of the spark plug and the ignition system as a whole can be determined based on the appearance of the electrode, the amount and color of carbon deposits on it. Brown soot is considered normal.

With long-term operation, the operating characteristics of the motor change. If you carefully monitor the operation of the internal combustion engine, then based on fuel consumption you can draw conclusions about the condition of the engine. Knowledgeable people recommend changing spark plugs on VAZs after 20 thousand kilometers, and in winter even after 15 thousand.

You can judge the need to replace the SZ by their appearance, more precisely in terms of the amount and color of carbon deposits, as well as the gap between the electrodes.

In addition, the dryness of the threads should be checked. If there are traces of oil on it, this indicates problems with the tightness of the system.

To summarize, we can cite cases when it is necessary to change the SZ:

• the car does not start well;
• fuel consumption has increased;
• the engine starts to stall;
• engine power decreases;
• exceeding the recommended mileage for replacement.

What candles should I put?

Choosing candles is a responsible matter. The service life of the engine, its power, fuel consumption, and successful starting depend on their quality.

When choosing, the greatest attention should be paid to the central electrode, such indicators as: heat resistance, thermal conductivity and ductility.

The best products are candles in which the smallest gap is 0.4 -0.8 mm, made from expensive materials: platinum, iridium, palladium coated with silver or gold (video author - Avtosferaomsk).

It is important to understand what spark plugs are produced for the VAZ 2114. When choosing a new product, you need to study its characteristics in order to choose. A large number of SZ manufacturers have appeared on the car market, but there are several leaders whose products are in greatest demand. SZ must work synchronously, so you need to buy them from the same manufacturer and from the same material.

Among the domestic manufacturers we can name those produced in the city of Engels. They are installed on VAZs from the factory. The quality of the products corresponds to the price, but there are defects, so when purchasing they need to be checked for serviceability. Products A-17DVRM (1.0) are produced for engines with injector 8 and A-17DVRM (1.0) - for 16 valves.

The best imported products are Czech ones. They are in demand due to their good quality. 10 series of these products are produced, differing in design. They have a clearance of 1.1, there is an SZ for 8 valve injection engines - BRISK SUPER FORTE LOR15YC-1 and for 16 valve BRISK SUPER FORTE DOR15YC-1.

Japanese products are always of high quality. These spark plugs are installed on some brands of cars directly at the factory. They have a higher price, but also have corresponding quality. When purchasing, you should beware of fakes, as there are a lot of them. For engines with 8 valves with an injector, DENSO W20TT is intended, for engines with 16 valves - DENSO W20EPR-U11.

NGK is a leading manufacturer of SZ. They are installed by manufacturers on some brands of foreign cars. As a car enthusiast, I claim that spark plugs last an average of 25-30 thousand kilometers. For engines with a 16-valve injector, NGK spark plugs No. 13 BPR6ES-11 are produced.

DIY replacement instructions

Replacing spark plugs on VAZ 2114 and 2115 is not a complicated process. This work can be performed by any motorist, guided by step by step instructions given below.

Tools and materials

To carry out the procedure you need to prepare:

• key for removing protection;
• a set of round probes;
• spark plug key;
• new set of SZ.

To avoid counterfeiting, you should purchase original products.

The process of dismantling and replacing SZ

The procedure for removing and replacing spark plugs should be carried out on a cool engine to avoid burns.

The process itself consists of the following steps:

1. First you need to open the hood. Then you need to remove the protection from the engine, if present.
2. After removing the decorative trim, you need to remove the protective caps that are placed on the contacts. The caps should be removed carefully so as not to damage the wiring.
3. The areas near the NW should be cleared of dirt so that they do not get into the engine cylinders.
4. Now, using a spark plug wrench, you need to unscrew the S3 from the cylinder head. You can start twisting from any side. First you need to move it from the dead center, and then you can carefully unscrew the SZ from the socket.
5. Having turned out the old SZ, you need to wipe the thread with a rag.
6. Before screwing in new products, it is advisable to check the gap on each of them. For cars with an injector, it should be from 1 to 1.13 mm.
7. Installing the SZ is the same simple procedure as unscrewing, it is carried out in reverse order. New products are placed in the seats of old candles. You need to screw it in carefully so as not to damage the threads in the cylinder head or on the product.
8. Next you need to put on the ends of the high-voltage wires. In this case, you need to make sure that the numbers of the wires that are printed on them match.
9. At the final stage, the decorative overlay is returned to its place.

After replacing the SZ, it is necessary to observe how the engine operates. If it works intermittently, it is possible that one of the SZ has defects. To detect it, you need to sequentially disconnect each high-voltage wire. A faulty spark plug should be replaced.
