The gas distribution mechanism in the Lada Priora car, as in any other car, from time to time requires diagnosis and repair. In particular, we are talking directly about the belt itself. Untimely replacement of this element and, as a result, its breakage can lead to expensive repairs. Now we will tell you how to replace the timing belt on the Prior and why it is necessary ( )
What is it for?
The mechanism strap is necessary so that the crankshaft and camshafts of the engine function synchronously. This is very important, since the inlet of gasoline and the removal of exhaust gases from the system depend on this.
When to change?

In several cases, an unplanned replacement of the strap may be required. For example, if you find traces of engine oil on it. If so, then the cause of the leak should be eliminated, and the element itself replaced. In addition, if mechanical damage appeared on the belt that could cause a break, the part must also be replaced with a new one. Or if the teeth began to fall away on the timing belt, this could also later cause an urgent component replacement.
Phased replacement
All work on changing the part should be done on a cooled engine.
1. First, you must dismantle the plastic protection of the element. Unscrew the pins with a wrench and remove the cover.

2. After that, put the first cylinder of the motor in the upper position. It is necessary to make sure that the marks on the camshafts coincide with the marks on the plastic casing.

3. Make sure that the marks on the crankshaft match the marks on the oil pump.
4. Take a wrench and unscrew the screws that secure the tension rollers.

5. Using a screwdriver, disassemble the timing belt. Check the position of the marks on the shafts. If they have moved, they should be set again.

6. Now, carefully, so that the marks do not go astray again, install a new mechanism strap. Use the roller to tighten the element. Then check the position of the marks again.
7. Reassemble in the reverse order.
8. Now check the tension. It is recommended that the crankshaft be turned in a circle a few turns, then check the position of the marks again.
9. The tension of the strap itself should be checked in the middle of the two rotating disks of the distribution pulley. The belt must not bend more than 6 mm. If the element is excessively overtightened, you will hear a characteristic sound. This, in turn, will significantly affect its service life.
