My thermostat housing decided to, well, "vent" coolant all over the place while driving home from work, so I decided it might be a good idea to change it out. While that process went very well thanks to the numerous write-ups and tips, except for one mishap. The connector that plugs into the water temperature sensor was so brittle that it broke. I have scoured Google searching for info on this thing, but can't find any. Help!

 

You're saying the connector, not on the sensor, but on the wiring harness fell apart?
Ugh, good luck, but there's no specific part call out just for that plug; typically it's a full or sub-set wiring harness that's sold as a replacement.
Honestly, find a wreck / part out MINI and cut off 4-6in back on the sensor plug and splice it in to yours.

That's what I was afraid of. You'd think that they would be out there somewhere....

Frustrating.

Thanks for your input!

 

Try realoem.com and enter your vehicle info. Maybe one of these will work?

RealOEM doesn't usually show the connectors and wires. Call your dealer and ask them as their software will list the parts you need. You will need to cut the old wires and butt splice the new wires in place.

 

Well, I was able to 'jimmy rig' what was left of the connector on to the Temp sensor to at least clear codes and make sure that there isn't anything else wrong. It is a temporary solution, as I am sure it is not weatherproof in any way, shape or form; but at least I can move the car and it is not in 'limp' mode.

I will hit the dealer this weekend and see if they can get me a pigtail, else I will go the junkyard route.

Thanks for all the help.

 

I am having the same issue. Did you have any luck finding the plug for the temp sensor. Mine broke internally and lost connection. the DME shows that the coolant temp is at -40 or not connected at all. Actually caused a no start condition on my daughter's 07 mcs. DME flooded the engine trying to start at what it thought was an extremely cold morning.

Sorry, no good source was ever found for a replacement.

I was able to jimmy-rig mine to work, but it isn't pretty. The only solution that was viable was to find a wrecked Mini in a junkyard and cannibalize the wiring harness to splice it in to your own.

Hope this helps!
