Checking of the Charge Air Cooler

Good airflow through the radiator and charge air cooler core is essential for proper engine cooling. The cores allow air passage, but form a barrier that tends to collect insects and airborne debris.

If the charge air cooler core fins are bent, use a small pair of needle-nose pliers or a small screwdriver to straighten them. If the fins are clogged, use compressed air or water directed from the fan side of the radiator core to backflush any material restricting airflow.

Ensure that the hoses are not chafing and that the system is closed with no air leaks.
