BMW thermostats are known to fail, but luckily they typically fail wide open - meaning that your car can still cool. We offer thermostats from various OE suppliers we trust along with upgraded motorsport specific thermostats where applicable to make sure your BMW stays cool on track.
The thermostat in your vehicle regulates coolant flow based on temperature. When you first start the engine, the thermostat remains closed to speed up the warm-up process. After a few minutes, it opens to allow warm coolant to circulate. If your vehicle is overheating but not producing warm air from the heater, a faulty thermostat is likely the culprit. A thermostat stuck closed prevents coolant from flowing, causing the engine to overheat. Conversely, if your engine isn’t reaching its proper operating temperature while driving, the thermostat may be stuck open, leading to inefficient performance. Replacing the thermostat will restore proper coolant flow and help regulate engine temperature. This high-quality thermostat from Febi is designed to fit like the original, ensuring your engine warms up correctly and cools efficiently. Since some coolant loss is unavoidable during a thermostat replacement, make sure to order the correct replacement coolant for your vehicle. Additionally, consider purchasing a new thermostat housing, as stock plastic units can become damaged or warped during removal.
