Necessary materials for replacing worn ones: depending on the model and equipment of the car, a V-belt or ribbed belt of length and type corresponding to the installed engine.
Attention! Cars with a 1.4-/1.6-liter engine with air conditioning, as well as all cars with 1.9-/2.0-liter engines, are equipped with a ribbed belt.
The ribbed belt is wider than the V-belt and has longitudinal ribs on its working surface. With its help, the auxiliary units are driven.
Due to the fact that the tension of the ribbed belt is adjusted automatically by means of a tension roller, its tightening is not required, and for this reason the ribbed belt can be classified as a maintenance-free part.
1 Replace the V-belt and ribbed belt if the following defects are present:
- A) wear, traces of oil and grease,
- b) cracks and loosening of the side surfaces,
- V) porosity, transverse cracks,
- G) deposits between belt ribs (see illustration).
12.1 Damage to the ribbed belt:
F - cord fringe
G - detachment of ribs
H - transverse cracks on the ribs
2. Check the tension of the V-belt by pushing it with your thumb in the middle of the section between the belt pulleys furthest apart.
When checking the tension of the ribbed belt on vehicles with a 1.4-/1.6-liter engine with air conditioning, as well as on vehicles with 1.9-/2.0-liter engines, tighten the belt only if it bends more than than 6 mm.
3. Vehicles with a 1.4-/1.6-liter engine without air conditioning. Check the tension of the V-belt. It should bend no more than 3 mm. Weak tension of the ribbed belt leads to increased wear and tear. Too tight a belt can cause damage to the bearings of the respective units.
