Mounting tension timing belt – this is one of the most complex works on car maintenance. Is it possible to do it yourself? Yes, but it does not require special tools, and precision and experience. But is it worth doing it yourself?
It should be noted that the timing belt change relatively infrequently - is taken into account the time he had already worked. Timing belt refers to the gas distribution system, which includes:

- camshaft;
- water pump (not necessary),
- tensioner and rollers.

timing system It carries the mixture of fuel and air but also removes the exhaust gases. Timing belt or chain rotates at several rollers and appropriately regulated tensioner. Thanks to this engine is running smoothly. That in this case can go wrong?
The weakest element of the system is a belt. Once used durable timing chain, which practically did not respond to the destruction, later they were replaced by belts. they are easier to, they are easy to pull, do not give a strong resistance, do not create a big noise, Plus, the face. However, it turned, that the belt wears out after a run, and it is very different. Some stand around 100 000 km, other 50 000 km…

It is screwed directly into the engine block, so that the possible disconnection will cause a lot of trouble. Sometimes it is possible to cut a new thread, but this extra work.
Then install the water pump, videos, and tensioner. Several times carefully read the user manual. This item is for as many specific, even too confident repairman manages to tie it the other way around. And it can lead to irregular operation of the engine and belt breakage, which leads to another failure.
Tension roller has special indicators, that must converge with labels on the engine block. It can be arrows, groove, cuts. It should be clearly set.
Tension the belt in the engine block, but so far only slightly. Now it's time to adjust in accordance with the operating requirements. It is for this handy torque wrench. As a rule it is necessary to set the value 20 nm, but it is necessary to clarify this in the manual for setting up video. It should fit snugly to the engine block, without slots, but it can not be screwed on too tight. If you followed the instructions exactly as it should be in order.
