97°C Thermostat Assembly for BMW N51/N52/N54 Engines

The Mahle-Behr 11537549476 is a direct-fit thermostat assembly, featuring OE quality and designed to replace the original unit in select BMW models equipped with N51, N52, and N54 engines. This thermostat opens at 97 degrees Celsius, ensuring your engine reaches and maintains its optimal operating temperature. A properly functioning thermostat is critical; failure in the open position can lead to a rich fuel mixture, poor fuel economy, and potential catalytic converter damage, while failure in the closed position can cause severe engine overheating and damage. Symptoms of a failing thermostat include an engine that does not reach its optimal running temperature or an overheating condition, which may also be accompanied by the radiator fan not engaging. Replacing a faulty thermostat is essential for the health and performance of your BMW. Mahle, a company with a history dating back to 1920, is a leading global manufacturer of automotive components.
