Installation Guide

The following steps outline a typical installation procedure for the Febi Bilstein 29232 Tensioner Assembly:

1. Safety First: Disconnect the battery and allow the engine to cool completely.
2. Remove Old Tensioner: Loosen the mounting bolts, release the belt tension by rotating the pulley, and carefully slide the old assembly out of its housing.
3. Prepare New Assembly: Inspect the new unit for any manufacturing defects. Apply a thin layer of anti‑seize lubricant to the bearing surfaces if recommended by the manufacturer.
4. Mount the Tensioner: Insert the new assembly into the housing, aligning it with the mounting holes. Tighten the bolts to the specified torque (typically 20–25 Nm).
5. Belt Installation: Route the auxiliary belt over the pulley and other components as per the vehicle’s belt routing diagram.
6. Final Checks: Reconnect the battery, start the engine, and observe the belt for proper tension and smooth operation. Adjust if necessary by loosening the mounting bolts slightly to allow the spring to take up slack.

Maintenance Tips

• Inspect the belt and tensioner every 30,000 km or as recommended in the vehicle’s service manual.
• Replace the belt if it shows signs of wear such as cracks, fraying, or loss of ribbing.
• Check for oil contamination on the pulley surface; clean with a non‑abrasive cloth and mild solvent.
• Avoid over‑tightening bolts during installation to prevent damage to the housing threads.
