Installation Notes and Tips

Verify engine application and connector/sensor configuration before installation. Inspect the mating surface, replace worn coolant hoses or seals as needed, and refill the cooling system with the correct coolant mixture after service. Bleeding air from the system is important after thermostat housing replacement to prevent hot spots and inaccurate temperature control.
