Radiator Leak Test, Removed From Vehicle

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: 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.
  1. Leak test the radiator in clean water with 138 kPa (20 psi) air pressure.
