Radiator Leak Test, Removed From The Vehicle
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. 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 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.
- Leak test the radiator in clean water with 138 kPa (20 psi) air pressure.
