Radiator Leak Test

RADIATOR LEAK TEST INSPECTION-2.3L

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.
