Charge Air Cooler (CAC) Cleaning

Flush the CAC internally with solvent in the opposite direction of normal air flow. Shake the CAC and lightly tap on the end tanks with a rubber mallet to dislodge trapped debris. Continue flushing until all debris or oil is removed.        

 CAUTION: Do not use caustic cleaners to clean the CAC.  Damage to the CAC will result.

 After the CAC has been thoroughly cleaned of all oil and debris with solvent, wash the CAC internally with hot soapy water to remove the remaining solvent. Rinse thoroughly with clean water.  Blow compressed air into the CAC in the opposite direction of normal air flow until the CAC is dry internally.  Refer to the vehicle manufacturer’s instructions for installation procedure.
