Procedures

Radiator Cleaning

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

Warning
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 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 radiator.
- Clean the radiator cooling fins.
- Straighten any damaged cooling fins.
