Leak from coolant temp sensor on elbow 2012 countryman S
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...

So I tried that O ring and its still leaking. I give up on this O ring search because i tried like 9 of them and NOTHING WORKED. Im forced to just succumb and replace the thermostat assembly. Im getting the housing and harness for a pretty decent price but now the next question i have is how do i eliminate this metal elbow, is there a replacement hose i need to get ? This is where my sensor is and its's what's currently leaking

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.

Cheapest option of repair and only takes about 20 minutes.

Remove the sensor from the elbow (two tangs you squeeze and it pulls out with a bit of finesse), clean the sensor and elbow of any coolant that may contaminate the seal (spray everything with brake clean), apply a bead of RTV around the existing O-ring and reinstall the sensor. Let the car sit, preferably overnight for a solid seal. Done it on multiple cars with great success.

You have to have it very clean if you do the RTV thing. Good luck.

After you have coolant clear of the seal seat just hit everything with brake clean, lay a bead around the o-ring, reinstall, live life. No scare tactics involved with the job.

Most people on the east coast are stuck right now, NYC, NJ some. Have you seen some of the MINIs on IG with tons of snow on them. Or buried.
