Important: Remove bugs, leaves, dirt and other debris by blowing compressed air through the engine side of the radiator.
- Some conditions may require the use oil and water and a mild detergent.
- Clean the A/C condenser fins.
- Clean between the A/C condenser and radiator
- Clean the radiator cooling fins
- Straighten any damaged cooling fins.
- Vehicles equipped with a diesel engine, clean between the charged air cooler and the A/C condenser also.
Removal of the charge air cooler may be necessary to clean the fins.
