BMW Cooling System Parts & Accessories for MINI

Clear BMW chassis

Please ensure your correct model is selected

The cooling system is arguably the weakest point in numerous BMWs. If you drive an aging BMW or plan on taking your car to the track like we do, we recommend beefing up your cooling system before going to the track. Generally, the main components in your cooling system that are prone to failure include the following: expansion tank, factory hoses, water pump, thermostat, fan (especially if your vehicle comes factory with a clutch fan), and radiator. Factory BMW expansion tanks are plastic and prone to either breaking off at connection points or combusting. As factory rubber hoses age they either crack or break over time - we offer silicone cooling hose upgrades for most applications to avoid future failures. If you have an older vehicle, your water pump likely comes from the factory with a plastic impeller - we offer upgraded water pumps with metal impellers that are far more reliable. Newer model BMWs utilize electric water pumps - BMW spent millions of dollars engineering these water pumps, but they fail so often that we recommend replacing at 60,000 mile service intervals to avoid being stranded on the side of the road. In terms of thermostats, we offer various upgraded thermostats for racing applications. If your BMW utilizes a clutch fan from the factory, we have several options available in terms of universal electric fans - we recommend replacing these to avoid sending brittle plastic fan blades through your hood. For radiators, we recommend swapping out your radiator for one that does not use plastic connection points like your factory radiator.

Have you ever noticed how crisp and responsive your MINI was after that initial warm-up period, and wanted to keep that feeling for the rest of the day? This 180° F Thermostat is the solution. Not only does the engine maintain its fresh-start power, but also the under-hood temperatures are greatly diminished (see comparison table below). Now when your car sits after a hard run it won't cook and dry out everything under the hood as bad as it did in the stock configuration. This is great for the MINI owner that lives in a hot climate, or those that push their cars hard at the track or local twisty road.

Please Note: This thermostat does not include a replacement gasket. Reuse the gasket from the OEM thermostat.

Cold Weather Alert: If you encounter weather below 50º F or 10º C, please be aware that the ECU could throw a “check engine” light. This is no cause for alarm as the sensors are registering an anomaly and the thermostat is not harming the engine. The “check engine” light can be reset with a diagnostic tool or left as is. Please call if you have questions.
