    Electric fan not running

    Well I went riding a few weeks ago and noticed that my over heating light came on. I saw it a little too late and my overflow cap came off and antifreeze boiled over. So the fan would run when the red over heating light would kick on but wouldn’t kick on at all when it got up to normal operating temp(where it should kick on). So wired the fan direct, it kicks on fine it’s not locked up. Replaced the Thermo sensor above the thermostat. Still fan doesn’t work. Checked the relay it works. I bought a Thermo Switch but cant find where it is located. It’s got two wires on it but can’t find it. After I find this switch and replace it, I might just run it on a toggle switch.

    If you have a 2019 X2 the thermo switch is located in the wiring harness. Go to Partspitstop web site and it shows that part number and a location. Difficult to explain but you can use that for a start. Most likely the same for a 2020. Electrical 3. Good luck.

    I probably should have mentioned that it’s a 2016 R-spec. Number 42 in the picture is what I’m looking for. It’s not on the chassis either.

    If the fan ever comes on then that isn't the problem. It is just a auto reset circuit breaker.

    You said fan will run when overheat light is on. That tells you that the part is passing current to the fan.



    The sensor in the thermostat housing controls the fan THROUGH the ECU.

    So what you're saying is that the ECU controls when the fan kicks on? Replacing the thermo fuse would essentially do nothing for me. So to fix the problem I would have to replace the ECU, which I probably won't end up doing. Instead I would just run it to a toggle switch and install a water temp sensor. It's strange that it seemed to happen all of a sudden on the trail. This thing has been a tank until this, first problem so far with 900 miles.

    Don't forget to burp all the air out of system. The thermo sensor at the t=stat stays in an air pocket and will not read properly until its bled. You should also replace your t'stat if you have overheated or at least pull it and check it, as often they get damaged.

    Yea I bled the air out before starting it up. When I install the temp sensor tomorrow I will have to bleed it all over again haha. I did an Ohm test on the old thermo sensor before I replaced it and it passed. (The resistance decreased when I put it in hot water) But I replaced it with a new one anyway. Now the thermostat itself I think is working because I removed the radiator cap when the motor was running while cold and it wasn't circulating but when the engine warmed I could tell the thermostat opened up because it was circulating. I might still replace it though just to be safe. I found a Wolverine fan override online for about 100 bucks that is looking like my best option at this point.
