How to select and change spark plugs for Lada Vesta 1.6 and 1.8

Spark plugs for Lada Vesta 1.6 and 1.8 are needed to ignite the fuel and if one or more of them stop working, this will affect the stability of the car. Proper and maintenance is required. It is important to pay close attention to the operation of the engine and its ignition system. In most modern 1.6 and 1.8 engines, flammable mixtures are ignited using an electric charge. It passes between the copper or nickel electrodes of the spark plugs.

Worn igniters cause serious technical problems:

• significant reduction in engine power;
• excess fuel consumption;
• catalyst overheating;
• detonation (explosive nature of fuel combustion).

Replacing spark plugs on a Lada West on time helps the car's engine run longer and more efficiently. According to the technical recommendations of the AVTOVAZ company, replacing spark plugs in a Lada Vesta car should be done every 30,000 km. Car owners note that ignition devices do not fail so quickly. Given the difficult practical operating conditions of the car, it is better to adhere to the rule of frequent replacement.

We will indicate signs of wear on the ignition system elements and tell you how to replace the elements yourself.

Changing spark plugs on Lada Vesta - instructions

Draw your attention to! All work must be performed on a cold engine. Firstly, this contributes to your safety - you won’t get burned on a cold engine. Secondly, spark plugs expand when the engine is hot, making them difficult to unscrew. And if you apply excessive force, you can completely break the thread.

1. Open the hood and remove the plastic engine cover.

2. Directly under the plastic trim we see a wiring harness that controls the ignition coils. Press the latch on the wire chip and remove it from the connector. We perform a similar procedure with the three remaining wires.

3. Using a 10″ socket, one by one, unscrew the 4 bolts securing the ignition coils and remove the coils.

4. Use a 16″ high socket or a special spark plug wrench to remove the spark plugs.

A little advice! If the spark plug remains in the spark plug well, it can be pulled out using a reel. We just put a coil on the candle and lift it up.

5. Next, you need to screw the new spark plugs into place. You need to wrap it without force and always by hand. If you feel force, it means the spark plug is not following the thread. Be sure to unscrew it completely, clean the threads and screw it back on.

Advice! Before wrapping the spark plug, it is recommended to lubricate the threads with a special high-temperature lubricant. This will prevent damage to the thread when unscrewing the spark plug.

The last step is to put everything back in place in reverse order and enjoy the work done.

Fresh ignitions: installation recommendations and purpose

Before you begin to study the method of replacing spark plugs in a Lada Vesta, you should find out what function they carry, and which spark plugs are installed on the model of the Russian automobile industry we are discussing. Spark plugs are needed to ignite the air-fuel mixture in the engine. The operation of the engine and other indicators will depend on the condition of the spark plugs:

• Fuel detonation;
• High fuel consumption;
• Power unit power;
• The catalytic converter overheats;
• The catalytic converter fails.

In general, replacement of spark plugs is necessary when there is a malfunction. If their condition is bad, then the engine is in the same condition. For example, oil marks on the threads or electrodes will tell you that the oil reflective caps are faulty.

Important The manufacturer indicates that replacement should be made every 30 thousand kilometers. Experts say that candles can last much longer. In this case, all operating instructions must be observed. The service life of spark plugs is reduced due to difficult operating conditions of the machine, low-quality fuel, and so on. You should always remember about timely replacement, which will protect the driver from troubles that may arise during the trip. The automotive industry recommends that all buyers of their cars install spark plugs that are compatible with a specific model. All types of candles are listed in the table below:

You can purchase candles easily and simply through specialized stores. One candle for the Russian Lada Vesta will cost between 60-1000 rubles. Accordingly, the cost depends on the material from which it is made and the manufacturer, plus some design features.

The car owner himself decides which products to install. There is now a lot of information available about the use of iridium and multielectron cells. If you delve into the topic and study the opinions of car owners who use different options in the ignition system of their cars, during operation they do not see any difference between such spark plugs. It must be remembered that cheaper ones will have to be changed more often. Also, iridium options must be installed and all recommendations of the automobile manufacturer must be followed.

Obvious signs of wear - you need to know

Spark plugs are a device for igniting gasoline. Lada Vesta is equipped with a 16-valve engine, that is, a spark plug set of 4 units is required.

We list the main signs that the spark plugs on a Lada Vesta need to be changed:

1. The starter operates with a delay, after several idle revolutions; 2. The ride of the car is not smooth, but with noticeable jerks; 3. Motor dynamics decrease; 4. Fuel consumption per 1 sq. km increases; 5. The color of the exhaust gases changes.

Sometimes the condition of the ignition device can indicate problems with other parts of the vehicle. For example, if the thread of the spark plug hole contains traces of oil on the electrodes, this means: the oil reflective caps have exhausted their service life. The service station staff will advise you when to replace the igniters. However, this period is also determined by the brand, and it can be found out from the factory operating instructions.

Spark plug sets for the 16-valve Lada Vesta are produced by different companies - both Russian and foreign.

Let's sum it up

Now you know how to change spark plugs on any Vesta engine. There are no difficulties in this matter. You can do everything yourself, you just need to follow the installation instructions and make replacements in a timely manner.

We replace spark plugs on a cooled engine. Remove the plastic protection from the engine.

What spark plugs to install and their price

The Lada Vesta VAZ-21129 engine uses original AU17DVRM spark plugs, where:

Table “

”

Standard domestic spark plugs are just enough for the intended period, but as noted by car owners, after half the service life, difficulties may arise when starting the engine in cold weather. Spark plugs produced by foreign manufacturers will be a worthy replacement:

Bosch - 0242235913. Price per set is 400 rubles. The cost of one such candle 0241235751 is 120 rubles. You can also find it cheaper, of the same brand, only Russian-made Bosch 0242235666 “Super plus” spark plug. Price – 80 rub./piece.

Yttrium F01H7B0146, a kit from this company will cost 220 rubles.

Spark plugs from more famous manufacturers such as Denso , spark plug “Nickel” Q20PRU11 and spark plug from NGK , product code 2330, will cost 100 rubles per piece. Spark plugs from the expensive price segment such as “Longlife” from VAG (made in Germany) product code 101905601F will cost 350 rubles/piece.

Many motorists advise purchasing spark plugs produced using new technologies. These innovations include iridium spark plugs. On the market they are represented by “Iridium Power” spark plugs from Denso, product code IK20TT, price 560 rub./piece.

But installing such expensive spark plugs on a domestic car is simply unprofitable.

If you find oil in the spark plug wells

The Lada Vesta has an unpleasant flaw. Insufficiently reliable sealing of the engine between the valve cover and the cylinder head. Because of this, oil gets into the spark plug wells. The problem can be fixed at the dealer under warranty - you just need to re-glue the camshafts and reliably seal the engine. Or contact a service station.

The problem occurs on cars where the manufacturer does not provide gaskets in the classical sense. An anaerobic sealant is used, which seals the cylinder head, camshaft bed and valve cover together.

In this case, given the inconsistent build quality of AvtoVAZ, there is a problem with the seal of the planes connecting in the upper part of the cylinder head. And since the oil pressure in the cylinder head is quite high (about 3-4 bar), the oil begins to flow into the spark plug wells

What are the dangers of oil getting into spark plug wells?

Due to oil leakage, the spark plugs and ignition coil fail faster. The spark plugs and coil do not break immediately after oil gets on them. But over time, the parts will fail - they are not designed to work in such conditions.

Many drivers note that due to oil in the spark plug wells, the engine begins to stall. It may also be harder to start. This is especially true during the cold season.

Damage to spark plugs, ignition coils and overall engine load depend on operating conditions. Many drivers who use their cars in a gentle mode only find out about an oil leak when replacing the spark plugs.

Until this moment, the malfunction does not cause discomfort. If the driver likes to drive aggressively, then the working life of the spark plugs, ignition coil and engine is noticeably reduced.

Replacing spark plugs on a Lada Vesta with your own hands

To carry out the work, you will need a 16 mm spark plug wrench with an extension and a special head with a rubberized coupling built into it, with which the spark plug is held, and a flat-blade screwdriver.

1. We take out the ignition coil of the first cylinder.
2. Using a 16mm socket wrench for spark plugs, unscrew the spark plug and remove it from the seat.
3. Remove the spark plug from the key.
4. Using a round feeler gauge, measure the gap on the spark plug electrode. If necessary, we adjust the gap by bending it. When checking the gap with flat feeler gauges, remember that it should be 1.0-1.15 mm.
5. We install the spark plug in the head of the key and screw it into the seat.
6. We carry out similar actions on the remaining cylinders. To prevent the threads in the cylinder head from breaking, you must first tighten the spark plug by hand. And only then, using a torque wrench and an extension, screw it into the spark plug well with a tightening torque of 30-40 Nm.
7. Perform the above operations on other cylinders.

Diagnostic information.

The M86 controller constantly monitors the current through the ignition coil. If there is no current or its insufficient value, a fault code is recorded.

General tips for connecting high-voltage wires.

Laying wires. Do not try to connect the wires in a bundle. Disassemble the wiring harnesses, release the wires from the plastic holders. Connect the high-voltage leads to the corresponding cylinder spark plugs. Lay the wires so that they do not rub against each other, engine parts, or hoses. Avoid sharp bends and tension on the wires. After connecting all the wires, secure them into the bundle with special comb holders included in the delivery kit.

The procedure for connecting I/O wires to a VAZ carburetor (2108, 2109, 21099)

The central wire from the distributor cover always goes to the ignition coil (bobbin).

The outlet of the distributor cover, which faces towards the front of the car, is connected to the first cylinder.

The outlet of the distributor cap, looking down, is connected to the third cylinder.

The outlet of the distributor cap, looking rearward, is connected to the fourth cylinder.

The outlet of the distributor cap, looking up, is connected to the second cylinder.

The procedure for connecting high-voltage wires to a VAZ Classic, Niva with a carburetor and distributor.

Central wire from the ignition coil (bobbin)

Injection VAZ produced before 2004 with an old-style ignition module (4-pin low-voltage connector)

Injection VAZ produced after 2004 with a new ignition coil (3-pin low-voltage connector)

As with the old-style ignition modules, the new coils are also marked with pins corresponding to the cylinders. But the connection order is different from the order on the old-style ignition module. Be careful.

On VAZ 2105, 2107 cars a contact (battery) ignition system is installed. Contact, since the operation of the entire system is based on the opening and closing of the breaker contacts in the distributor. Unlike a similar contact ignition system for cars 2101-2106, the VAZ 2105, 2107 uses switching of low voltage wires through a mounting fuse block.

Elements of contact ignition system

1. Generator

Provides an electric current of a certain voltage to the ignition system when the engine is running.

2. Battery

Supplies the generator with electric current and starts the engine.

3. Fuse and relay mounting block

Switches low voltage wires of the ignition system.

4. Ignition coil

Distributor breaker R-125V or 30.3706. The breaker mechanically opens the low voltage (12V) current circuit, which signals the ignition coil to generate high voltage current.

6. Ignition switch

The ignition lock (switch) closes the electrical circuit of the ignition system, thereby allowing low voltage current to flow from the generator to the coil.

7. High-voltage wires (armored wires)

They transmit high voltage electric current from the distributor to the spark plugs.

8. Spark plugs

They produce an electric spark at the onset of the compression stroke in a specific engine cylinder.

9. Capacitor.

The capacitor enhances the spark and prevents contacts from burning.

Notes and additions

High-voltage wires of VAZ cars are one of the most important elements in the ignition system. It is the wires that transmit high electrical voltage from the module to the spark plug.

Failure of the wires affects not only the formation of a spark, but also the operation of the entire power plant. This article will talk about how to correctly select and independently replace high-voltage wires on a VAZ car.

Below we discuss the procedure for connecting wires to the ignition module, as well as examples of the highest quality and best wires that can be purchased in terms of price and quality.

Features of igniters for 16-valve VAZ 21129 and VAZ 21179 engines

Vesta is produced with a 16-valve engine. Let us dwell separately on sixteen-valve engines. Technologically, they are more complex and sensitive to the choice of fluids, and require greater oil consumption.

They have 4 valves per cylinder (a total of 16 valves), therefore fuel consumption is reduced and engine power is increased by 15-20%. In the 16-valve VAZ 21129 and VAZ 21179 engines, BCPR6ES and FR7DCU (manufactured by NGK and Bosch, respectively) are good options for replacing these spare parts. Models from well-known companies Denso, Brisk, JSC Robert Bosch Saratov.

We have listed the types of ignition devices that are needed for a Vesta car. By following the rules, you will ensure your car has a long service life and will be able to save on repairs in the future.

Spark plugs for Vesta need to be selected based on the cost of the engine. Lada Vesta has 4 gasoline engines in its arsenal:
