On a VAZ 2115 car, the timing belt is replaced in the same way as on the other front-wheel drive models of this brand. Repair can be carried out independently, the main thing is to install all the pulleys on the labels. Given the fact that motors with 16 valves were not installed on the 15th VAZ model, we can talk about the relative ease of the replacement. Before starting repairs, you need to study the theory - sequence, features.
When do you need to change the belt?
The first, most unpleasant case is a broken belt. This happens often, so it is advisable to have a spare in the trunk. The cause of the breakage is excessive tension, the development of pulleys, exceeding the service life, as well as insufficient belt reliability. Before replacing a timing belt with a VAZ 2115, you need to evaluate its appearance and operating time.
If he has served for more than two years or more than 45 thousand kilometers, be sure to replace him. 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 general technical condition of all components and assemblies is rather sad. Accordingly, the belt drive will wear out more.
What else to change with a belt?
It should be immediately mentioned that the cooling system pump and antifreeze have a service life of not more than 90 thousand kilometers or a maximum of 3 years of operation. With an annual run of 30 thousand km, all antifreeze additives evaporate, which leads to poor cooling. As for the pump, it breaks, its pulley acquires a play, as a result of which the belt slides a little during operation.
Also, a new tension roller is installed. Its life is the same as that of the belt. If it fails, then an extraneous sound appears on the timing side, indicating a 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 on the pulleys (or their life has exceeded the mark of 120 thousand km. Mileage), it is advisable to replace them too. Otherwise, new belts will wear out faster and breakage is possible.
Repair Tools and Preparation
In fact, a quick replacement of the timing belt VAZ 2115 is possible if you have experience and a tool. You will need:
- The key is "10".
- The key is to "17".
- Special key for tensioning pulley.
- Jack.
- The key is "19".
That's all, now you can start the replacement. If a breakdown 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, a break occurs without consequences. Disassembly Procedure:
- Loosen the bolts securing the right wheel to the hub.
- Lift the right side with a jack. It is advisable to lock the left rear and apply the hand brake.
- Remove the bolts from the plastic cover that covers the timing belt compartment.
- Loosen the nut securing the roller.
- Loosen and remove the alternator belt.
- Remove the bolt from the crankshaft pulley.
- Remove the timing belt.
Installing a new timing belt
When the timing belt is replaced on a VAZ 2115 car, it is important to place the correct marks. They are in three places:
- On the camshaft pulley and ICE head.
- On the crankshaft pulley and engine block.
- On the flywheel and the plate screwed to the engine block.
The last marks can only be seen if the rubber plug is pulled out of the clutch housing. To install a new belt, you first need to place all the pulleys on the labels. Then put the belt, but note that a slight displacement will occur during stretching and the ignition timing may change. Next, the assembly is performed in the reverse order of disassembly. On a VAZ 2115 car, the timing belt was replaced successfully. Collect everything, install the cover, trying not to lose the rubber seal. It avoids the ingress of dust and water into the belt compartment of the gas distribution unit.
