Radiator Leak Test
RADIATOR LEAK TEST INSPECTIONCaution: Never leak test an aluminum radiator 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.
Note:
^ Always install plugs in the oil cooler fittings before leak - testing or cleaning any radiator.
^ Clean the radiator before leak - testing to avoid contamination of the tank.
1. Remove radiator.
2. Leak - test the radiator in clean water with 138 kPa (20 psi) air pressure.
