Operation CHARM: Car repair manuals for everyone.

Maintenance Recommendations

The front face of the radiator should be cleaned periodically. Bugs, leaves, etc., can be removed by blowing compressed air through the radiator, from the engine side of the radiator toward the front of the car. If compressed air is not available, a water hose can be used to force water through the radiator, from the engine side toward the front of the car.

CAUTION: Never spray cold water on a hot radiator. The radiator fins are necessary for adequate heat transfer. They should not be brushed, as doing so damages the fins and reduces heat transfer.
