I have a 2011 Chevy Cruz Eco and recently the engine light has come on and the fan won’t shut off. The temp never gets hot and it seems to run fine aside from the loud fan! I’m at 128,000 miles so I don’t think there’s any warranty I qualify for. Anyone have any suggestions to avoid a pricey dealership repair?

 

Possibly the fan relay contacts are welded together. Unplug it. Turns off, replace the relay

 

This is a common problem....i surmise that if you had the codes checked, you would get P0597/P0598--has everything to do with chevy switching to a thermal housing instead of a simple thermostat. If you look online for that code you will see a lot of chevy's are having problems with this. I'm currently having this problem and "patiently" waiting for some Chevy Rep to actually contact me. I have to pass a emissions test for my Chevy this month, but I can't pass while experiencing these codes.
