Installation Notes and Tips

Verify the thermostat style, flange dimensions, and 180°F temperature specification against the original part before installation. Clean the housing sealing surfaces thoroughly and inspect the coolant system for corrosion, debris, or gasket residue that could affect sealing. Because no gasket is listed with this part, use the correct service gasket or seal specified for the vehicle application.
