Radiator Cleaning

CAUTION: NEVER spray water on a hot radiator. The resulting steam could cause personal injury.
NOTE: The radiator fins are necessary for good heat transfer. Do not brush the fins. This may cause damage to the fins, reducing heat transfer.

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