Charge Air Cooling System Cleaning

WARNING: This page is about a different car, the 2022 Cadillac CT5. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

NEVER spray water on a hot heat exchanger. The resulting steam could cause personal injury.

CAUTION:

The heat exchanger fins are necessary for good heat transfer. Do not brush the fins. This may cause damage to the fins, reducing heat transfer.

NOTE:

Remove bugs, leaves, dirt and other debris by blowing compressed air through the engine side of the charge air coolant radiator.

Some conditions may require the use of warm water and a mild detergent.
Clean the A/C condenser fins.
Clean between the A/C condenser and charge air coolant radiator.
Clean the charge air coolant radiator cooling fins.
Straighten any damaged cooling fins.
