Radiator Leak Test - Removed From the Vehicle

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. If a separate tank is not available, drain and rinse the test tank before testing an aluminum radiator.

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.
