Leak from coolant temp sensor on elbow 2012 countryman S
#26
So it was 52 Degrees here yesterday so I decided to give this a shot. Im happy to say that the bead of Permatex Black Silicon did the trick. I applied it on the upper portion of the O ring and made sure everything was 100% clean and 100% dry (I spent about 10 minutes cleaning and drying everything).I let the car sit overnight and this morning i checked and everything was DRY! I drove to work parked it up and 8 hours later I checked and we're still DRY. I just got under the car 4 hours after getting home from work and we're still DRY!!!
MISSION IS A SUCCESS!
Thank you all so much for you input on this issue...
PS: My Ducati radiator is leaking now from one of the rows, I swear I can never win when it comes to coolant leaks lol. Luckily I have a spare lower radiator in my garage for this bike (lower rads are known to leak on the Streetfighter models)

Now as for that Ducati, I'll take it off your hands. I've got a '14 Ruckus, gets me scene points but not the satisfaction of a sports bike.

Glad it held.

This sensor just started leaking on my wifes '12. I could not find the sensor/o-ring/metal elbow listed on the RealOEM.com parts fisch site.
I thought I was going crazy, but it looks like Mini/BMW updated this part,correct? There are no Mini dealers in Idaho so I cannot easily confirm this.
Reading thru this thread it appears that the updated parts are a new upper radiator hose assembly and a new thermostat/housing assembly? And possibly a new wiring harness?
Can anyone confirm this? And if so, what are the necessary parts/part #'s for the updated assemblies?
Thanks.

Steve, that's right. You'll need the following:
replacement upper radiator hose
new thermostat housing assembly
wire harness adapter kit
coolant / distilled water
Do what i did and save yourself the trouble and $400 + and get a tube of black Permatex gasket maker, take the sensor out and clean everything thoroughly with brake cleaner and apply some gasket maker on the ORING then pop it back into the elbow and let it sit over night. It worked for me and is still holding. I put approx 3k miles on my car since i did this.

I just got home after being away for the weekend to find this sensor leaking coolant all over the driveway on our 2012 Countryman S, auto. Ours has just over 60k miles on it so it is out of warranty unfortunately.
The check engine light came on for the coolant temp sensor circuit recently as well so I had planned on doing all these updates anyway but I knew it was not a crucial repair needed immediately, now I have no choice.

As the title states I have a leak coming from the temperature sensor on the metal elbow on my 2012 countryman S. I replaced the O ring with an autozone brand O ring that worked for a few days then the leak happened again. Do you guys know where I can find an O ring for this ? Dealer wont sell just the O ring unfortunately...
Cheers to those of us who tolerate all the quirks with the first-gen Countryman.

Just an update, we finally found out that OEM part number for the sensor and the O- Ring. 13621433077 is the oem MINI part and 13621433077S is the O ring. We have it updated on our site. Its not even in the ETK. But we found it.

Same issue-Themostat replaced
The dealer just replaced my thermostat and hoses including the o-ring (I asked). They said the issue was part of a recall for the thermostat on our cars but they couldn't replace it (for free) after 67k miles. You've probably solved this by now? but just in case someone else with the issue reads this - check with the dealer about this recall.
Cheers to those of us who tolerate all the quirks with the first-gen Countryman.

I think I might have the same problem. Came home from work and coolant was dripping from the rear area of the motor. When you called the dealership did you have to really work them to get them to replace it under the warranty?

It's a terrible design, no O-ring will fix it indefinitely.
We remove the sensor, clean the surfaces, and apply black RTV to it and reinstall.
Never leaks again, not to mention it's a useless sensor once you replace the thermostat, new thermostats have the temp sensor where the bleed screw was, and you're left with a potential leak point from the old sensor.

You saved me some inconvenience and money with this DIY fix.

My fan switch started leaking last week. Today identified it's the source. The body of the sensor has some play in the metal receptacle of the elbow. This last year I replaced the thermostat/housing and water pipe. The new housing had the relocated position of the sensor with a new wiring pigtail to adapt to old OEM wiring harness. Can we eliminate the switch/sensor entirely? Replace the metal elbow that doesn't have the sensor orifice? Almost thinking this could be a universal part as long as the OD was same size. Any code to be set if the electrical connector isn't connected to this now defunct sensor?

You can replace it with the metal elbow without the connector or just slap some black rtv around the sensor and slap it back in unplugged.
I have mine with a nice bead of black rtv around it and a zip tie holing it in place. No more leaks. And no, you don't throw a code.
