Radiator Leak Test, Removed From the 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: Always install plugs in the oil cooler fittings before leak testing or cleaning any radiator.
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) air pressure.
