Radiator Leak Test Inspection - 3.0L

WARNING: This page is about a different car, the 2007 Mazda B3000. 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.

  1. Remove radiator.
  2. Leak-test the radiator in clean water with 138 kPa (20 psi) air pressure.
