Installation Notes and Tips

Verify the inlet and outlet sizes, core dimensions, and crossflow layout against the original radiator before installation. Inspect hoses, clamps, and surrounding cooling system components for wear, and replace any damaged parts during service. After installation, refill and bleed the cooling system according to BMW procedures to help prevent air pockets.

Quality Assurance

OSC tests the radiator core before assembly and tests the completed unit again after assembly. The transmission and engine oil cooler circuits are also tested before installation into the tank when equipped on the application. This multi-stage testing process supports consistent fit and function for BMW Z3 radiator replacement applications.
