Recently my car would overheat but I fixed it with a thermostat swap. But I noticed that my aux fan never turned on. I know that at 88 degrees Celsius it's supposed to come on to help the radiator fan. My question is, can I rig it to work at all times? I searched on the forum and couldn't really find anything that helps. It would help to keep it simple as possible as I am not tech savvy.

You can force the fan on by jumpering the thermo switch connector. But there's no need to do that if the rest of the cooling system is operating correctly. Though you should find out why the fan didn't come on when the engine overheated and fix that.The car makes it possible, but the driver makes it happen.

I would make sure all leaks are taken care of, then flush it and bleed really well with BMW coolant and maybe water wetter. See if that alone does it.
It hasn't overheated ever since my thermostat change. I feel like if i left the bad sensor in, it would have. There was a pretty steady stream of coolant coming out of it. But yes i bled it again after the sensor aswell. Thanks for the help guys. I really appreciate it.
