Since the wiring harness and the type of Temperature Sensor changed thru the iterations, the replacement Thermostat Housing (which may look different than the one on the car) may require a 'Wiring Adapter' in order for proper connection to the wiring harness on the car.
  • If your MINI has an alloy 'right angle' elbow in the upper radiator hose with a temperature sensor, the updated thermostat housing will replace this elbow with sensor. You can eliminate this elbow with a new one-piece radiator hose.

Question:
I have a question about the thermostat housing for my MINI Cooper. It has a straight temperature sensor that screws into the top of the housing.
Answer:
Looks like you have the R58 Cooper S Coupe with the N18 engine built in 09/2011.
If the temp sensor on top looks like it can be removed, you can try replacing it with this, but there is another sensor below that is not removable so this may not solve the issue.
You can also try this bypass sensor which fits into the bleed valve, but again, this may or may not solve the problem.
I would recommend you replace the entire thermostat housing:

Question:
I'm ordering the part number #G2NME1129 thermostat housing and have some questions. 1) Does the thermostat come included with the housing? 2) Does the coolant temperature sensor come with the housing? a) If so, will I need anything else? b) If not, will I need an adapter or multiple and which ones? 3) My engine should be N18B16A, is the coolant temperature sensor on the thermostat housing stock or on the upper radiator hose elbow? It's too tight to really get a good look.
Answer:
Thanks for your questions:
1. Yes, the thermostat is molded into the housing, so it is one unit all inclusive
2. Sensors are included with the housing.
3. Let me know the last 7-digits of the vin number to identify the correct replacement thermostat, and whether your MINI requires an adapter or not. 

If your MINI has the alloy elbow with the sensor in the radiator hose, that setup has been discontinued and replaced by the new thermostat housing. (Your MINI will probably require an adapter to connect the new design thermostat housing to your existing harness.) You can disconnect the connector at the elbow and tie it off unconnected.

You have the option of leaving that elbow in place (if no leaks are present) or you can replace it with this new hose that eliminates the elbow and sensor.

Question:
I'm looking for the correct thermostat for my New MINI Cooper S. I see that you may require an adapter but i don't know why. can you guide me through?
Answer:
The correct thermostat housing replacement to fit your 2013 R56 MINI Cooper S Hardtop built in 12/20/12 with the N18 engine and automatic transmission is our G2NME1129 with the G2NME1142 Adapter B.

The adapter is necessary for some MINIs because there has been several iterations of the thermostat housing to correct some design deficiencies. These newer housings were designed to fit the newer models which has different electrical harness connections. In order to fit these newer housings in older models with different electrical harness, the adapters are necessary. Otherwise, the electrical plugs would be incompatible. Depending on the production date, the housing and adapter requirements may be different.

I hope this helps.

Question:
I'm trying to replace a thermostat housing in this mini and I'm hesitant to order the housing itself because none of them look like the housing that's in the car. Honestly I'm not even positive what the vehicles engine code is because I don't understand the specification between "hard top" and "coupe" as this vehicle is both. I'm fairly certain this vehicle will require the adapter but any insight would be appreciated.
Answer:
There has been several revisions of the thermostat housing, which is the reason why they may not look like the one in the car. An adapter is sometimes necessary to connect the new style housing to the existing harness. You have a 2012 R56 Mini Cooper S built on 05/28/2012 with the N18 engine and automatic transmission.

The correct replacement thermostat housing according to the MINI catalog is our G2NME1129 with the Adapter A G2NME1141 

If you have the elbow with a sensor, that sensor is replaced by a new one in the thermostat housing. You can disconnect it and tie off the connector. The new adapter should take care of the connection to the new housing.

If you want to eliminate that elbow (it can leak over time), here is the replacement hose without the elbow.

Question:
I have a MINI Cooper S 1.6L manual N18 R56 5/2012 the problem that does not turn on the cooling fan for the radiator.
Answer:
It sounds like the radiator fan is not operating. Checked all the fuses. 

The radiator fan is controlled by the computer-based on the following inputs:
- engine speed
- load
- driving speed
- intake air temperature
- coolant temperature

If you haven't replaced it yet, the symptoms you describe can be corrected with the replacement of the thermostat housing.
