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

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:

Blow compressed air through the engine side of the radiator to remove any foreign material, such as insects, leaves, and dust.
