Product Description

Keep your BMW’s engine operating at the correct temperature with this Arrowhead Thermostat 108°C, designed for precise temperature regulation within the cooling system. The thermostat plays a crucial role in opening and closing coolant flow to maintain optimal engine performance and prevent overheating.

This thermostat is specifically engineered for a range of BMW models, including F20, F21, F22, F23, F30, F31, F10, X1, X3, X4, X5, and Z4 models equipped with the N20 engine. Always verify your vehicle’s model, year, engine size, and engine code to ensure compatibility before purchasing.

Common symptoms of a faulty thermostat include engine overheating, erratic temperature gauge readings, poor heater performance, increased fuel consumption, and coolant leaks around the thermostat housing. Addressing these issues promptly helps prevent further engine damage.

Replace the thermostat at the first sign of malfunction or during scheduled cooling system maintenance. It is especially important to do so if you notice temperature fluctuations or coolant leaks, as these can quickly escalate into more severe engine issues.

Order your Arrowhead thermostat from MiMi Auto Parts for reliable fitment and peace of mind. We offer nationwide delivery throughout South Africa, so you can get your BMW back on the road quickly and safely.
