Product Description

This Arrowhead thermostat housing is a key component in the cooling system of select BMW models, designed to securely house the thermostat and manage coolant flow between the engine and radiator. The robust plastic construction includes an integrated hose outlet and a pre-installed green gasket, ensuring a reliable seal and efficient installation. It is suited specifically for BMW vehicles, helping to maintain optimal engine temperature and prevent overheating.

This thermostat housing is compatible with a range of BMW models, including popular series such as the F20, F30, E90, F10, X1, and X3, particularly those equipped with N47 engines like the 120d and 20d. Before placing your order, please confirm your BMW's model, year, engine size, and engine code to ensure the correct fitment.

Common symptoms of a faulty thermostat housing include coolant leaks around the housing area, engine overheating, fluctuating temperature gauge readings, low coolant warnings, and visible cracks or warping on the housing. You may also notice poor heater performance or frequent need to top up coolant.

If you observe any of these signs, replacing the thermostat housing is essential to prevent engine damage and maintain proper cooling system function. Always check compatibility details and consult your mechanic if you are unsure about the replacement process.
