Installation Notes and Tips

Verify the thermostat temperature rating, bypass dimensions, and flange measurements against the original part before installation. Because no gasket or seal is included, reuse only if serviceable or source the correct sealing components separately. Clean the housing mating surfaces thoroughly and inspect the cooling system for contamination, trapped air, or worn hoses before refilling.
