Sealing flange on pulley side. Torque and tightening sequence
Tighten the arrow bolts to a final torque of 9 Nm in stages, crosswise.
Removal the poly V-belt
Remove the front noise insulation. Risk of damage to the already used poly V-belt when changing the direction of rotation. To reinstall the poly V-belt, mark the direction of rotation with chalk or a felt-tip pen before removing it. To loosen the poly V-belt, move the tensioner clockwise "arrow". Remove the poly V-belt and loosen the tensioner.
Installation
Installation is in the reverse order, while the poly V-belt should be placed on the pulleys in the indicated sequence:
1. Generator; 2. Intermediate roller; 3. Coolant pump; 4. Power steering vane pump; 5. Air conditioning compressor; 6. Tensioner element of the poly V-belt; 7. Torsional vibration damper with poly V-belt pulley
Note: When installing a poly V-belt, ensure that it is positioned correctly on the pulleys.
Start the engine and check the running of the poly V-belt. Install sound insulation.
Removal the tension element of the poly V-belt
Remove the poly V-belt. Remove cover "1" and unscrew the bolts located behind it. Remove tension element "2" of the poly V-belt from the cylinder block.
Installation
Installation is in the reverse order, in this case the poly V-belt must be installed.
