My Brat is currently set up to have the fan on whenever the key is turned. It is great in the summer time except in the winter I can not seem to get my BRAT warm enough to where it shoud be running. My white brat still has the thermoswitch on it, how do I install it back into normal working conditions on my blue BRAT?

 

Kyle.

im using a aftermarket thermofan controller wired into the temp sensor on the side of the radiator

I would look at the wiring on the White Brat and see what needs to be put back to stock on your Brat. That fan should not be on full time. It will take longer to warm up meaning you get bad gas milage as well as wearing the fan out prematurly. The stock fan coming on when it should will keep your car in the right temperature setting.

Yeah I know. I am sick and tired of going out 30 minutes early on morning to let the old girl warm up. Main reason I have been driving Legacy.

 

I replaced the thermostat with OEM and that helped a little bit but I think it all boils down to the fan running constantly. It was rigged up to a stupid blue ricer switch so it could be fast and furious but that dang thing quit working. Keep the advice coming guys. Thanks.
