Radiator: Testing and Inspection

CAUTION: Do not leak test the aluminum radiator in the same water that leak tests copper/brass radiators. Flux and caustic cleaners may be present in the tank and will affect the aluminum. If possible, use a separate, clean test tank for aluminum radiators. If conditions do not allow for a separate test tank, clean the test tank thoroughly each time before testing an aluminum radiator. Clean the radiator before leak testing it to prevent contamination of the test tank.

Leak test the radiator in clean water with 157 kPa (23 psi) of air pressure.
