Radiator: Testing and Inspection

Radiator Leak Test, Removed From the Vehicle

CAUTION: Do not leak test an aluminum radiator in the same water that is used to leak test copper/brass radiators. Flux and caustic cleaners may be present in the test water which will corrode aluminum.

Clean the radiator before leak testing to prevent contamination of the test tank. Leak test the radiator in clean water with 138 kPa (20 psi) air pressure.
A separate clean test tank is recommended for aluminum radiators.
