Typically referred to as the thermostat neck / housing, this part mounts on the highest point on the head and controls the flow back to the pressure tank. Cracking, which usually occurs around the gasket seal and leaks, are symptoms that it’s worn out. This item does not include the thermostat.

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.

A thermostat that opens sooner promotes better cooling in your vehicle. Running a lower temperature thermostat will keep everything much cooler. Keeping the engine cooler will help reduce and improve the life of the seals in your engine, saving you time and money, while also help increase engine performance. A tune might be required to gain the most from this modification, as well as to get your car's ECU accustomed to seeing lower temperatures.

If your vehicle is experiencing cooling issues, chances are the thermostat is the cause. Common symptoms include prolonged warm-up at highway speeds from the thermostat being stuck open, or consistent overheating issues from the thermostat being stuck in the closed position. Either condition can result in poor performance, and potential damage to vital components in your vehicle.

The thermostat on your vehicle controls the flow of coolant based on temperature. When you just start your engine, the thermostat remains closed to accelerate the warm up process. After a few minutes, it opens up to allow the warm fluid to flow. If your vehicle is overheating but not blowing warm air from the heater, the problem is more than likely your thermostat. If the thermostat gets stuck closed, it allows no fluid to flow and ends up overheating the coolant already in the engine. To fix this problem and get your vehicle's heat restored, replace your thermostat. Complete assembly, including housing.
