Installation Notes and Tips

Confirm the outlet style, inlet diameter, and bolt-hole spacing before installation. Clean the mating surface thoroughly, inspect the hose connection for wear, and replace any damaged coolant hose clamps or adjacent seals as needed. Because the thermostat is not included, reuse or replace the thermostat separately if your application requires one. Verify fitment against the vehicle listing for your Chevrolet or GMC model before assembly.
