Radiator Leak Test, Removed From Vehicle
WARNING: This page is about a different car, the 2013 Ford Mustang. 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 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 air pressurized to the maximum pressure listed in the Specifications table.
