Radiator Leak Test, Removed From the Vehicle
WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. 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:
Clean the radiator before leak testing to avoid contamination of tank.
- Leak-test the radiator in clean water with 138 kPa (20 psi) air pressure.
