Radiator Leak Test Inspection - 2.3L
WARNING: This page is about a different car, the 2005 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.
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.
- Remove radiator.
- Leak-test the radiator in clean water with 138 kPa (20 psi) air pressure.
