Radiator: Testing and Inspection

CAUTION: Do not leak test the aluminum radiator in the same water that copper/brass radiators are tested in. Flux and caustic cleaners may be present in the tank and will affect the aluminum. A separate clean test tank is necessary, if possible, 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 123 kPa (17.8 psi) of air pressure
