Complaint:

Squeaking noises from the belt drive

Cause:

Axial shifting (temperature-related) of the individual belt pulleys and guide pulleys can lead to squeaking noises in isolated cases.

Remedy:

Application of Krytox lubricant - belt dressing A000 989 36 60 (from lubricating kit A000 580 03 50) - one to two drops at each point to the inner

and outer side edges of the poly-V belt. Procedure:

- Bring the engine to the operating temperature (80 deg. C) and switch it off.

- Remove top front engine cover as required to get access to the poly-V-belt.

- Apply one to two drops of Krytox lubricant to the inner and outer side edges of the poly-V belt near the top idler pulley (important: only treat the

edges of the belt. If the lubricant is applied to the running surface of the belt, this can cause the poly-V belt to slip).

- Start the engine so that the lubricant can spread along the edges of the belt.

* Sufficient for 15 cars, Submit as Local Purchase - KRY00284, Qty 1, handling is included
