Charge Air Cooler Overview

NOTE:

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 of the same type as those equipped by the factory.

To mount the charge hoses on their connectors securely, spray the bolts on the used clamps with rust remover before installing.
