My check engine light come on and the engine cooling fan was on high so I looked up this site and found that the thermostat was probably the problem, I changed out said thermostat this morning and everything is back to normal. This site is awesome!!
Thank you.

engine coolant fan running all the time on high
I noticed that my engine fan run running high--loud enough such that I could hear it in the cabin. After I parked, I left the car idling... but the fan failed to shutdown. (2012 chevy cruze)

2014 acting up with only 33k miles
My car is doing this constantly. I paid enough for it that this is just poor manufacturing. Annoying as hell and very unnerving when deciding to drive any distance but dealer says, nothing wrong. Ya, right. Poor service

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.

Frustrated!!!!
On my way to work this morning, I noticed that my engine fan run running high--loud enough such that I could hear it in the cabin. After I parked, I left the car idling... but the fan failed to shutdown. I have seen others with the same concern... and my car if out of the warranty period. Has anyone received assistance from GM regarding this issue?

Fan constantly running. Check engine light on
I am having the same issue as all of you. For the last two years my fan would come on constantly while I’m idle. I brought it in to Chevy and was told that was normal. Today my check engine light is on and the fan ran the whole time. My wife is due to have a baby any day and I need to be able to rely on my car. Does anyone know if it is safe to drive with?
