Thermostat housing replacement wiring question
I’m in the process of replacing the thermostat//housing on my 2011 Mini Cooper Countryman All4 S. My car came with the older housing type with just one plug. I had to order the coolant thermostat adapter lead Part Number12518611289This is a two wire setup. The new thermostat has one sensor on the top front and one towards the back on the lower side. Anyone know which of the two wires go to which sensor? They are the exact same plug and came with no directions.

You are correct. For anyone with a question on this in the future, these plugs have a small fin on them that is unique to each plug that ensures you can’t plug the wrong one into the wrong sensor.

For some you may be able to swap them. For the models that require the coolant adapter lead because of the Tstat housing change, they aren’t interchangeable.

I also own a 2011 and notice there is very little heat during the winter season, can I ask why you actually replace your original unit, will you be doing the installation yourself.
Should I be replacing my unit with the part number you included, I read previously that you had to order a separate cable .. please confirm and include the part number of the cable.
Thanks

With the new thermostat housing PN 11537647751 the 2 x 2pin connecters from adapter PN 12518611289 all electrical connections are accommodated for the thermostat.
On my old Thermostat setup (2012 Countryman ALL 4) there is an 45 Degree aluminum fitting in the large hose to the radiator that has a connector in it.
Do I just leave this connection open with the new setup?
Thank you

Actually the build date is 01/2012, lol. So who knows. It appears that there were several revisions throughout production to several different parts. I recently did a turbo upgrade on another 2012, and found several small differences in part design and placement. Not with the turbo, but especially with some of the plastic parts
