Radiator: Testing and Inspection

COMPONENT TEST - RADIATOR LEAK TEST, REMOVED FROM VEHICLE

CAUTION:Never leak test an aluminum radiator in the same water that copper/brass radiators are tested in. Flux and caustic cleaners can be present in the cleaning tank and they will damage aluminum radiators.
NOTE:Clean the radiator before leak testing to avoid contamination of the tank.
1. Leak test the radiator in clean water with 138 kPa (20 psi) pressurized air.
