13621433077 Coolant Temperature Sensor in Lower Radiator Hose Compatible with BMW E87 E81 3er E46 E90 E91 5er E39 E60 F10

I installed this in my 2012 Mini Cooper Countryman S. The car was throwing the code for coolant temp sensor. I popped this one in, cleared the code from the car with a simple code reader and it has been great. I originally purchased a sensor from the dealer. They used the VIN to let me know which sensor I needed. The dealer was wrong but not really their fault. Some of these cars had revisions mid production and they put a different sensor in them. Our VIN called for a sensor that has an angled plug coming off of the metal base but that does not work. The straight plug I bought here works. Hopefully this helps if you are in the same predicament I was in. The only thing I had to do to this part in this listing is the tabs on the side that lock the part in place where ever so slightly to big. I filed the plastic on the tabs just a tiny tiny bit and this part snapped right into place. I just finished a 700 mile road trip with the part from this listing and zero issues. Just a side note which has NOTHING to do with this part. There are other plugs you have to remove to get to this part. If you do not get them plugged in all the way it will cause computer to throw a new code for "Crankcase breather Circuit Open." Make sure you get all of your small plugs pushed back together VERY well and it will fix that code. In the pictures the angled sensor is the one from the dealer and the straight sensor is the one i removed from my car. Dealer said this part is located in the thermostat housing but that is not correct either. This sensor is located in the metal elbow located just next to the thermostat housing. I included a picture of this as well. The mid year revision to these cars made this way more complicated than it had to be Shame on Mini Cooper for not updating their system to show the actual parts these cars need.

Good replacement, easy to install, but it didn’t fix the P0128 low temp fault which is probably caused by the other temp switch which is located on the engine block under the manifold and a much harder fix.

So far - so good. Fixed two problems we thought were related to potentially faulty Auxiliary Electric Cooling fan: 1) Auxiliary Electric Cooling fan intermittently ran at Full "High Temp" speed, even when engine was warming up or on cold days. Unusually loud. 2) This condition also forced the engine management system into a "LIMP HOME" mode, significantly reducing engine power. Not only that, replacing this Coolant Temp Sensor on the lower radiator hose is super easy to do, compared to most BMW engine sensors. In the end, the Auxiliary Electric Cooling was always working fine. Good Luck !

Perfect product it was exactly what I was looking for. For the price the quality was exceptional indistinguishable from OEM. I have a BMW Z4 and what tends to happen with these coolant sensors is that the O ring around it starts to wear out and get deformed so it lets coolant through and out the sensor under pressure. I popped this one on real quick and had no problems whatsoever after. I can't talk on durability is I've only had it on for a few hours but to my eye it look like it would last for a while. For anybody wondering how to test the pressure and find the leak in a cooling system get yourself a coolant system pressure tester ( AutoZone usually has a loaner tools for this ). pump up the pressure as much as you can not passing 10 psi which if you have a least you won't be able to anyways. And as you're pumping look and listen for any coolant coming out of any hoses, radiator, sensor, or even engine. If you have a coolant leak you won't even be able to put any pressure. If you don't have a leak and or to test if you fixed it you should sustain at least 5 or 10 psi without losing any pressure. Just make sure when you testing it you don't pass 10 to 15 psi as it's not needed and you could damage something. I hoped it helped someone

I bought this because the temp sensor on mine sprung a leak. I hadn't heard the best things about these Amazon parts, so I just used the o-ring from this with my original sensor since mine was still good. So far so good, no leaks after 500 miles so far.

Nice easy fit and no trouble codes. Temperature reads accurate.

I have a 2011 which was a year mini was swapping engines and used a thermometer like this. Mine started leaking so I bought this. My car constantly thought it was overheating when it wasn’t. Maybe this was calibrated at different temperatures than what my mini needed. Just a heads up. I ended up replacing the whole thermostat and it doesn’t even use a temperature sensor like this anymore.

Good product
