4. Bolt.
5. Guide roller cover.
6. Poly V-belt guide roller: 40 Nm.
7. Bolt.
8. Belt drive pulley for water pump.
9. Bolt.
10. Water pump.
11/12. Bolt.
13. Bracket of the power steering pump.
14. Sliding sleeve.
15/16. Bolt.
17. Power steering pump.
18. Belt drive pulley for the power steering pump.
19. Bolt.
20. Poly V-belt tensioner: 40 Nm.
21. Compressor bracket: when installing, pay attention to the position of the mounting bushings.
22. Bolt: 20 Nm.

24. Bolt.
25. Mounting sleeve: 2 pieces.
26. Tension element cover.
27. Torsional vibration damper: with V-belt pulley; due to the offset holes, installation is only possible in one position.
Sealing flange on pulley side - last and tightening torque
Tighten the arrow bolts to a final torque of 9 Nm in stages, crosswise.
Removal
Remove the front noise insulation shield "1". There is a risk of damaging the previously used poly V-belt when changing it. Install in reverse order, adjusting its running direction. For reinstallation, before removing the poly V-belt, mark its direction of travel with chalk or a felt-tip pen. To release the poly V-belt, tilt the tensioner clockwise "arrow". Remove the poly V-belt and relieve the tensioner.
Installation
Installation in reverse order. Place the poly V-belt in the correct order on the pulleys.
1. Generator. 2. Guide roller. 3. Water pump. 4. Power steering pump. 5. Air conditioning compressor. 6. Tensioner element of the poly V-belt. 7. Torsional vibration damper with poly V-belt pulley.
When installing a poly V-belt, it is necessary to ensure that it is positioned correctly on the pulleys. Start the engine and check the belt operation. Install the front noise insulation screen.
Removal and installation the poly V-belt tensioner
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 in reverse order: install the poly V-belt.
Removal and installation the torsional vibration damper with a V-belt pulley
Remove the poly V-belt. Unscrew bolts "1" and remove the torsional vibration damper with the poly V-belt pulley.
Installation
Installation in reverse order. Replace the vibration damper bolts. Due to the offset holes, installation is only possible in one position. Install the poly V-belt.
