Charge Air Cooler Assembly Overview: Notes

NOTE:

Before testing or performing a repair, check all air guide pipes and hoses and all vacuum lines for leaks and secure seating.

The hose connections as well as the air guide pipes and hoses must be free of oil and grease before installing.

Secure all hose connections with hose clamps appropriate for the model.

In order to be able to securely mount the air guide hoses on their connectors, spray the screws on the previously used clamps with a rust remover.
