Chevrolet Sonic Repair Manual: Radiator Cleaning

Warning:

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

Caution:

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.
