Installation Notes and Tips

Replace the thermostat only after the engine has cooled completely and the cooling system pressure has been relieved. Because the gasket or seal is not included, verify the correct sealing component before installation. Follow the vehicle service procedure for coolant refill and air bleeding to avoid trapped air in the system.
