Radiator Leak Test, Removed From the Vehicle

CAUTION: Never leak test an aluminum radiator or intercooler in the same water that copper/brass radiators are tested in. Flux and caustic cleaners may be present in the cleaning tank and they will damage aluminum radiators and intercoolers.

NOTE: Clean the radiator or intercooler before leak testing to avoid contamination of tank.

1. Leak test the radiator or intercooler in clean water with 138 kPa (20 psi) air pressure.
