My check engine light came on in my 2011 chevy cruze and my fan and began to run out of control.. continuously. Although the reading is always normal on my temp gauge. Two sperate mechanics both stated different causes to the fan continuously running. One assumes its the o2 sensors and the other suggest the thermometer and i cant get a clear answer so im unsure if this is mechanic-customers pocket talk or maybe it is both. Please help

 

Since your check engine light is on, go to Autozone or Advance Auto parts and they will check the code for you for free. That could help tell you what is causing the problem.

 

a engine coolant temp fault will cause the cooling fans to run continuously. +1 for getting the code read and post it here.

 

took it to autozone they said thermostat changed it and the fan and check engine light still on HELP .....

 

start a new thread. find out the code and post it.

 

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.
