VAZ 2115: timing belt replacement

By car VAZ 2115 timing belt replacementis produced in the same way as on the other front-drive models of this brand. Repair can be carried out independently, the main thing is to install all the pulleys by the marks. If we take into account the fact that engines with 16 valves were not installed on the 15th model of the VAZ, we can speak about the relative simplicity of the replacement. Before starting repair, you need to study the theory - the sequence, features.

When do I need to change the belt?

The first, most unpleasant incident is a belt break. This happens often, so it is advisable to have a spare in the trunk. The cause of the breakage is excessive tension, generation of pulleys, excess of service life, and insufficient belt reliability. Before you change the timing belt to VAZ 2115, you need to evaluate its appearance and operating time.

If he served more than two years or more than 45 thousand. km mileage, be sure to replace it. The fact is that he has a maximum service life of 60 thousand kilometers. But if the car is already "aged", it is better to reduce this figure, since the overall technical condition of all units and units is quite sad. Accordingly, the belt drive will wear out more.

What else to change with the strap?

It should be mentioned right away that the system pumpcooling and antifreeze have a service life of not more than 90 thousand km of run or a maximum of 3 years of operation. With an annual mileage of 30 thousand km, all additives from the antifreeze evaporate, which leads to a deterioration in cooling. As for the pump, it breaks, its pulley acquires a backlash, resulting in the belt slipping slightly during operation.

Also, a newtension roller. The term of its operation is the same as for the belt. If it breaks, then from outside the timing there is a strange sound, which speaks of the malfunction of the VAZ 2115 roller. Replacing the timing belt implies the installation of a new tension roller. In the event that there is wear of the pulleys (or their lifespan has passed the mark of 120 thousand km of run), it is desirable to replace them too. Otherwise, the new belts will wear out more quickly, and a breakage is possible.

Tools for repair and preparation

In fact, a quick replacement of the timing belt VAZ 2115 is possible if you have experience and tools. You will need:

1. The key is "10".
2. The key is "17".
3. Special key for tensioning roller.
4. Jack.
5. The key is "19".

That's all, now you can start a replacement. If the breakage caught you on the road, but there is a spare belt, do not despair, after a few minutes you will start the engine and continue driving. On eight-valve engines, as a rule, the breakage occurs without consequences. Disassembly procedure:

1. Ослабьте bolts of fastening of the right wheel to a nave.
2. Raise the right side with the jack. It is desirable to fix the left rear part and squeeze the handbrake.
3. Unscrew the bolts from the plastic cover that covers the compartment with the timing belt.
4. Ослабьте a nut of fastening of a roller.
5. Loosen and remove the generator belt.
6. Remove the bolt from the crankshaft pulley.
7. Remove the timing belt.

Installing a new timing belt

When a VAZ 2115 car is replaced with a timing belt, it is important to place the marks correctly. They are in three places:

1. On the pulley camshaft and the engine head.
2. On the crankshaft pulley and engine assembly.
3. On the flywheel and plate, screwed to the engine block.

The last tags can be seen only in thatIf you pull out the rubber plug from the clutch housing. To install a new belt, you first need to place all the pulleys along the marks. Then put a belt, but keep in mind that when you stretch a small displacement and the timing of the ignition can change. Next, the assembly is done in the reverse order to the disassembly. By car VAZ 2115, the timing belt replacement was carried out successfully. Collect everything, install the lid, trying not to lose the rubber seal. It avoids the ingress of dust and water into the belt compartment of the gas distribution unit.
