📋 Procedure
- Remove any noise insulation General body repairs, exterior66Noise insulation.
- Remove radiator grille General body repairs, exterior50.
- Remove front bumper General body repairs, exterior63Bumpers.
- Remove charge air cooler .
- Remove viscous fan .
- ⚠ Under no circumstances may the engine be turned counter to its direction of rotation (arrow B) at the viscous fan shaft (arrow). This can result in the shaft being loosened and the vehicle breaking down. When tightening the viscous fan bolt, only counterhold in the engine's direction of rotation (arrow A) using the open-end spanner3312. — Cut through viscous fan poly V-belt (1) using commercially available side cutters (arrow).
- Remove poly V-belt.
- Fit new poly V-belt (1) on viscous fan pulley.
- Mount poly V-belt fitting tool T50045 on vibration damper.
- Tension poly V-belt (1) in (direction of arrow) using poly V-belt fitting tool T50045.
- Turn engine in (direction of arrow) at crankshaft, thereby fitting poly V-belt (1) onto vibration damper.
- The remaining installation steps are carried out in the reverse sequence.

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
