Radiator Leak Test
RADIATOR LEAK TEST INSPECTION-4.0L
Caution:
^
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.
