Checking the belt surface
1. Turn the engine over a few times, this is the only way you can see all the surfaces of the V-belt. Often there is one, but a deep crack on the belt; when checking, this crack can fall just on the pulley.
2. When checking the V-belt, if there are uneven abrasion marks on the side surfaces of the belt, a porous or fringed surface, or even cracks in the belt, then the V-belt must be replaced with a new belt or a belt in good condition.
Belt tension check
1. Press hard with your thumb (with a force of approximately 5 kg) on a tensioned belt in the middle between two pulleys. The belt should bend no more than 1.5 cm.
2. Press the belt with more force. The belt should flex with resistance and the idler pulley should move out of the way. When the belt is released, the roller returns to its previous position and tightens the belt. If the belt lies loose on the wheels, this indicates a defect in the tension roller. Possible second reason: You may have forgotten to remove the locking pin from the tensioner.
Replacing and tensioning the V-ribbed belt
4-cylinder engines
1. Dismantling: Using a felt-tip pen or wax pencil, draw an arrow on the belt in the direction of belt movement. When viewed from the side of the belt, the motor rotates to the right, i.e. clockwise. The designation of the direction of travel is important if the same belt is subsequently installed. When installed in the opposite direction, belt wear increases, the belt may break.
Tensioner Rotation
2. To loosen the V-ribbed belt, turn the tensioner (shown by arrow).
3. Using a marking mandrel (e.g. T10060) lock the tensioner in the place indicated by the arrow.
Tensioner stop
4. Remove poly V-belt.
5. Install the belt in reverse order. Pay attention to the reliability of the installation of all units (generator, vane pump, air conditioning compressor). Pay attention to the direction of movement of the belt, as well as the correct fit of the belt on the pulleys. The belt is first laid on the air conditioning compressor.
6. Start the engine and check the running of the belt.

6-cylinder engines
1. Dismantling: Remove the engine top cover. With a felt-tip pen or wax pencil, draw an arrow on the belt in the direction of the belt movement. When viewed from the side of the belt, the motor rotates to the right, i.e. clockwise. The designation of the direction of travel is important if the same belt is subsequently installed. When installed in the opposite direction, belt wear increases, the belt may break.
Removing the engine cover
2. To loosen the belt, use the lever (it is recommended to use lever 3299 with nozzle 3299/1) turn the poly V-belt tensioner in the direction of the arrow.
Tensioner Rotation
3. Remove the belt from the power steering pump pulley.
4. Install the belt in reverse order. First of all, the V-ribbed belt is laid on the crankshaft pulley. The belt lining ends at the tension roller. Pay attention to the correct fit of the belt on the pulleys. Start the engine and check the running of the belt.

If the vibration damper was removed, then during installation, pay attention to the following:
4-cylinder engines
Lock bracket in service position, V-ribbed belt removed. Vibration damper (pulley) must only be installed using original screws. Mounting is only possible in one position. Hole (arrow) vibration damper should be above the projection on the toothed belt wheel.

6 cylinder engine
Lock bracket in service position, V-ribbed belt removed. (It is not necessary to loosen the central screw to remove the vibration damper). Installation using original screws only. notches (arrows) in the vibration damper must match the locking lugs on the toothed belt wheel.
