Most car enthusiasts and Samara owners are wondering how often spark plugs should be changed. Let's try to find the answer to this and many other questions regarding such an important element in the car as candles. They seem like small things that can fit in the palm of your hand, but the car won’t move without them.
WHAT ARE CAR CANDLES
A spark plug is a small part of a car engine that creates an electric spark that ignites the fuel-air mixture. Using a spark, it creates a mini-explosion in the cylinder, due to which the piston begins its movement. The number of such mini-fuzes in . Ordinary business class cars, and in particular cars, have four-cylinder engines, which means there are 4 units installed in it. But there are elite class cars or sports cars. They have six- to eight-cylinder internal combustion engines, respectively, 6-8 pieces are installed.
Let's consider spark plugs. As mentioned above, 4 pieces are installed in the VAZ internal combustion engine. Each consists of a nickel housing, a contact rod protected by a ceramic insulator. A spark occurs when the central and side electrodes come together.
It is important that everything is synchronized, which means that they must be from the same manufacturer and the same brand, that is, from the same materials. It is not advisable to replace one or two spark plugs. If it’s time to change, then it’s better to have all 4 at once.
DEFECTS AND DAMAGE TO SPARK PLUGS
During operation, damage and defects may appear on the spark plugs. Sometimes they are the result of improper operation, sometimes due to the wrong brand of spark plugs. Defects on the spark plugs can also help diagnose engine problems. You will learn from this section of the article what will happen if you do not change the spark plugs if defects occur. The brown color of the electrodes and the absence of damage indicate that the spark plugs are operating normally, and you can continue to drive.
Examples of defects and description:
- Electrodes and housing. This defect indicates that the removable rings on the pistons are worn out and require replacement. It is the rings that allow oil to pass through, and the plugs filled with liquid spark irregularly and detonate. The engine needs to be repaired urgently. Dirty igniters must be washed from oil, dried and inspected. If there are no other defects, then they can be left for further use.
- Electrode insulation is broken . You cannot drive with chipped insulation; you need to change the spark plugs, as they cause detonation in the engine.
- Plaque on the surface of the body indicates low quality gasoline. It is necessary to change the gas station that sells the surrogate, and the coating that prevents the spark from occurring, and you can continue to drive them further.
- Overheating of the housing is indicated by white spark plugs or a worn out upper electrode. Ignition devices can overheat for two reasons:
- You use high-octane gasoline, which means you need to change its brand;
- The type of spark plugs does not match your engine, and therefore neither do they.
- A lean mixture and the formation of carbon deposits inside the cylinders are indicated by the white color of the insulator with a smoky tint to the body and slightly melted electrodes.
- Painting of the housing and contact in a golden or glossy color, as well as mechanical damage, indicate that this brand spark plugs are not suitable for your engine. The last defect occurs due to the excessive length of the element. Incorrectly selected, long specimens can damage the piston. Therefore, they also need to be replaced.
A worn spark plug is perhaps the most correct type of malfunction. It says that the ignition process was carried out correctly, the internal combustion engine is working normally, but the time has come to replace them with new ones.
HOW OFTEN DO YOU NEED TO CHANGE SPARK PLUGS?
Your car will tell you when to change the spark plugs. Just be more careful about it. Listen to the engine. And as soon as you feel that the sound or rhythm of its operation is changing, open the hood and check the spark plugs.
If the problems described above occur, or at the first signs of wear, the ignition elements must be replaced immediately. During normal operation, they must be replaced after 30-40 thousand kilometers. There are also platinum and iridium igniters, their service life is approximately twice as long as that of conventional ones. But they cost more. Such candles are more of a luxury for the VAZ 2114 than a necessity.
Well-functioning spark plugs will keep the engine running. On the contrary, if they spark intermittently, this will affect engine power and the amount of unburned vapor will increase. . The engine itself, running on worn or defective spark plugs, will not last long.
They don't cost that much to save on. Moreover, this saving will be akin to the eccentric who lit a 10 dollar bill to find a 10 cent coin in the dark.
WHAT CANDLES TO CHOOSE FOR VAZ 2114
The auto parts market provides a fairly wide selection of igniters for the VAZ 2114. Here and Russian manufacturers, and Western European, and, of course, Japanese. Below you will find out which spark plugs for Samara models are preferred by the owners of these cars.
- DVRM AU17 from Engels is installed by the VAZ manufacturing plant itself on its cars. These spark plugs are recommended for car owners of their models. Car enthusiasts themselves believe that DVRM are good igniters for these cars. True, according to the same car owners, sometimes they come across a defect. Therefore, before installation it is necessary on the stand. On average, a set of 4 pieces costs about 200 rubles.
- Czech Brisk spark plugs have also proven themselves to be reliable and are in demand among VAZ 2114 owners. This manufacturer produces 10 types for different models foreign cars, including for motor vehicles. They cost about the same as Russian DVRMs.
- DENSO Japanese candles do not require special recommendations. Many foreign car factories install them on their car models. True, they are much more expensive than domestic and Czech brands - 350-400 rubles per set, but they also last longer than their European and Russian counterparts.
It’s up to you to decide which spark plugs to put on the VAZ 2114 – expensive or cheap, branded or just popular. The main thing is that they match your engine type and work properly.
HOW TO CHANGE PLUGS IN A CAR?
Changing spark plugs in a car is not difficult; any car owner can handle this operation on their own.
If you decide to start replacing them off the road, then let the engine cool. Otherwise, you can burn yourself and damage the thread when unscrewing, since the heated metal expands.
- Open the hood; if you have a protective cover, you need to unscrew it and remove it. The contacts are equipped with protective caps with high-voltage wires. They must be carefully removed, holding them by the caps, but under no circumstances pull on the wires. You can break the connections, and then you will have to change the wiring.
- Around the ceramics from the nest, it is necessary to remove all carbon deposits and debris that have accumulated here. Otherwise, all this dirt may end up in the engine cylinder.
- To remove the spark plugs, carefully unscrew them with a wrench. Having moved from the dead point, try to unscrew it. Do not rush, you can damage the threads of the socket or body. Try screwing it in again a little, and continue turning it out carefully.
- After unscrewing the old spark plug, clean the threads from dirt with a rag. Screw in the new one. When you feel that the thread is tight, make a quarter turn, but do not overtighten, otherwise you may ruin the thread of the cylinder, or the element itself.
- Place the high-voltage caps on the contacts, replace the casing, and close the hood.
For the first two or three days, observe how your new thing works. It is possible that a defect may occur, then the engine will operate intermittently. If this happens, you can determine which spark plug is defective by sequentially disconnecting the wires. Be sure to replace the rejected part.
Replacing spark plugs is a regulated operation. They must be replaced every 15 thousand kilometers. This is because threaded connection spark plugs and cylinder head (cylinder head) lose their tightness over time, so even if the spark plug works normally at low and medium loads, then at high blood pressure misfires in the combustion chambers. Also see replacing spark plugs on Lada Priora, Kalina and Granta cars or.
Replacing spark plugs must begin by removing the “-” terminal from battery. In order not to confuse the order of the high-voltage wires in the future, it is necessary to remove the protective cap only from the spark plug that you are changing at the moment.
Removing the protective cap from the spark plug
you need to unscrew it either with a standard spark plug wrench or with a 21mm socket.
After you have removed the spark plug, you need to check the gap between its electrodes using a special tool. For VAZ 2108, VAZ 2109, VAZ 21099 cars with carburetor engine modifications, the spark plug gap should be 0.7-0.85 mm, and for VAZ 2108, VAZ 2109, VAZ 21099, VAZ 2113, VAZ 2114 and VAZ 2115 cars with injection With engine modifications, the spark plug gap should be 1.00-1.13 mm.
If the gap differs from the above, it must be adjusted by bending the side electrode of the spark plug.
Having screwed in the new spark plug all the way, you need to tighten it with force, but not excessively. This is within a quarter of a turn after the spark plug touches the cylinder head. In case of excessive force, there is a risk of stripping the threads in the block head, which entails its repair.
Having installed the protective cap on the spark plug, we repeat the operation with the remaining spark plugs in the same sequence.
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 go further, carefully remove the high voltage wire from the spark plug of the 1st cylinder and place it on the cylinder head. Take off high voltage wires it is necessary to hold them by the protective cap, and in no case by the wire itself, since in this case you can break the contact between the wire and the cap, after which you will have to replace the armor wires.
After this, it is necessary to mechanically clean the 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 will sooner or later give results and cause damage piston group 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 reverse side and again try to carefully unscrew it. 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.
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 watch carefully operation of the internal combustion engine, then based on fuel consumption we can draw conclusions about the state of the SZ. 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.
From domestic producers can be called, 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 thanks to good quality. 10 series of these products are produced, differing in design. They have a clearance of 1.1, there is SZ for 8 valves 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 injector 16 valves are available NGK spark plugs No. 13 BPR6ES-11.
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 wrench;
- 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:
- First you need to open the hood. Then you need to remove the protection from the engine, if present.
- 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.
- The areas near the NW should be cleared of dirt so that they do not get into the engine cylinders.
- 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.
- Having turned out the old SZ, you need to wipe the thread with a rag.
- 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.
- Installing the SZ is the same simple procedure as unscrewing; it is carried out in the reverse order. New products are placed on seats old candles. You need to screw it in carefully so as not to damage the threads in the cylinder head or on the product.
- 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.
- 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.
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 to be of high quality and reliability of their 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 auto parts successfully cope 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:
- 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.
- Disconnect the on-board network. To do this, disconnect the negative terminal of the battery.
- 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:
- Stop the operation of the power unit. Wait until it cools down to an acceptable operating temperature.
- Lift the hood lid. Using a special design, fix it in the open position.
- Grasp the rubber caps of the high-voltage wires and carefully pull them out of their installation locations.
- Clean the surface from dirt using a brush.
- Unscrew the ignition element using the key.
- Carry out similar actions with the remaining candles.
- Check the new spark supply element. Measure the gap between the electrodes.
- Tighten the consumable by hand. Complete an action using a tool.
- 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’s 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 pressing the gas pedal sharply;
- 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.
