If there are cracks or fringes at the edges, the belt should be replaced.
Too tight tension of the belt leads to its stretching and to the destruction of the base, as well as increased load on the bearings of the drive units. Too little tension causes the belt to slip on the pulley, it becomes very hot and wears out prematurely.
With strong pressure with your thumb on the belt in the segment between the pulleys, the amount of belt deflection should correspond to the data in the table.
After installing a new belt, after a run of 100 km, it is necessary to check its tension and, if necessary, tighten it.
Attention! When checking the tension of the ribbed belt on vehicles with four-cylinder engines manufactured from 10/91, the belt must be loosened and retensioned.
The tension of the alternator rivulet belt on vehicles with six-cylinder and diesel engines is automatic and therefore does not need to be adjusted.

2. Remove the engine mudguard.
3. Loosen the clamping bolt on the power steering pump tensioner.
4. Turn the adjusting slot nut until the belt is properly tensioned (see illustration).
5. Tighten the clamp bolt.
If the power steering pump does not move, loosen the alternator mounting bolt on the bracket.
A/C Compressor V-Belt
Vehicles with four-cylinder engines
The A/C compressor V-belt tension is adjusted by removing or installing spacer washers between the front and rear of the V-belt pulley (see illustration 4.0).
More spacer discs between pulley halves results in less belt tension. Fewer spacer discs between pulley halves results in increased belt tension (see illustration 4.0a).
Additional spacers are installed between the pulley hub and the pulley front.
The pulley fastening nuts are tightened with a torque of 25 Nm. Make sure the belt is not wedged between the pulley halves.
6. Rotate the crankshaft 2 times.
7. Check the belt tension by firmly pressing the thumb on the belt in the section between the crankshaft and the air conditioning compressor.
8. Start the engine and let it run for a while.
9. Check for proper belt tension and, if necessary, add or remove spacers.
With the correct tension of the belt, tighten the assembly pulley mounting bolts again with a torque of 25 Nm (see illustrations 4.0b and 4.0c).

10. Turn away nuts of fastening on a tension level and on a rotary bracket.
11. Turn the adjusting bolt to the left (unscrew) to tension the belt.
12. Tighten the mounting nuts.

13. Turn out clamping bolts at the left and on the right on an arm of the compressor of the conditioner.
14. Turn an arm of the compressor of the conditioner together with the compressor to the right. Use the mount if necessary. When the belt tension is correct, tighten the clamp bolts.
