Replaced the thermostat housing on my daughter's 2010 Mini S, due to leaking. We are now plagued with engine codes indicating its not running warm enough. An OBD2 reader indicates its running about 65C. The car has been to 2 different shops now, to now avail, 2 different OEM housings, but can't get the engine to run warm enough. I don't know what the 2nd electrical connection (no the temp sensor)on the housing is for, but could it possibly telling the thermostat to remain open. is it possible, the computer has to be told the thermostat was replaced?
The second connection on the thermostat housing is for the heating element:
The heating resistor is fitted in the wax element of the thermostat. When the ECM applies power to the heating resistor, the wax element expands and closes the inlet from the cylinder head against the pressure of spring. The spring has the task of pressing the thermostat back into the rest position when the wax element cools down.

Happy Motoring
I have a 2011 Mini Cooper non turbo. I’m having problems finding the right thermostat housing. Hoping that you could tell me what is going on, my housing has a flat 4-pin connector on the control valve and a very small diameter temperature sensor that threads in to a small hole in the housing, and has a long lead going to a plug down lower. All of the housings that I can find have a square 2-pin connector for the control valve and a large temperature sensor that is held in with a clip. I have read about a wiring adaptor but don’t know if that is what I need or what adaptor I need any help would be appreciated.
It is very possible that the replacement thermostat housing will be different from the one on your MINI since they have updated the design on some models (some models already has the newer housing). The only way to identify the correct replacement for your MINI is by looking up the vin number in the MINI catalog. Your MINI may or may not require an adapter to connect a new thermostat housing to your existing wiring harness. If you send the last 7-digits of your MINI's vin number to [email protected], we can identify the correct replacement as listed by MINI.
