xOverview
The A-Premium Engine Coolant Thermostat and Housing Assembly with Sensors is a practical replacement built for Mini Cooper models from 2007–2013 and the Mini Countryman 2011–2013. It combines a thermostat housing, two-pin temperature sensors, and an integrated sensor harness in one kit, tailored to the 1.6L DOHC layout. This unit is designed to fit the original design and electrical layout of the listed vehicles, helping you restore steady cooling system operation without guessing at compatibility.
The assembly comes with everything needed for installation, including mounting hardware and an O-ring for a reliable seal. The thermostat opening temperature is rated at 221°F, providing a defined threshold for coolant flow that supports consistent engine temperature management under typical driving conditions. Note that for builds before 3/2012, you may need the original harness (Part No. 12517646145) for proper electrical fitment.

What to Expect in Real-World Use
When installed, the assembly supports steady cooling system performance across daily driving, errands, and highway trips. The integrated sensors provide consistent data points for monitoring engine temperature and coolant flow, which can help you identify anomalies early and plan maintenance before problems become noticeable. The tactile build and precise fit give a sense of reliability when replacing a worn component in a crowded engine bay.
Installation Considerations
- Check vehicle compatibility with your specific Mini model year and engine designation to ensure a smooth retrofit.
- Prepare for harness compatibility if your build predates March 2012, as noted in the fitment details.
- Handle with care to preserve sensor connectors and O-ring integrity during removal and reinstall.
- Keep in mind the 221°F thermostat opening temperature as part of your cooling system expectations.
