Thermostat

The thermostat in your MINI or BMW engine is a valve that ensures that ensures your engine stays at proper operating temperature by regulating the flow of coolant through the cooling system. If your thermostat is starting to fail you could be facing overheating problems that can cause significant damage, seeing poor fuel economy, or be very cold inside during the winter. Browse the category below to find the thermostat that fits your vehicle and don't forget the necessary gaskets and thermostat housings.

Every item we sell comes with a 100% satisfaction guarantee and a MINImum one-year warranty, and a two-year warranty on every part with the Bavarian Autosport brand. Because we use the same manufacturers as BMW, all of our parts meet or exceed the OEM equipment.
