Radiator Leak Test, Removed From Vehicle

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. 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: Always install plugs in the transmission fluid cooler fittings before leak testing or cleaning any radiator.
NOTE: Clean the radiator before leak testing to avoid contamination of tank.

Leak test the radiator in clean water with pressurized air to the maximum pressure listed in the Specifications.
