I have a 2007 Chevy cobalt LS with a 2.2 liter ecotec engine, I am having problems with the coolant temperature sensor. I have replaced the sensor twice already and it continues to act up. It will not read when the outside temperature is below 60 degrees Fahrenheit. If I start it from a cold start then drive for a few miles it will read up to 170F° then it will hover around 165 to 170 then it will get stuck on a random temperature in between Then it will read followed by the radiator fan coming on and running constantly. After all of this happens the engine light will come on after a few more miles. Can someone please help me?
have the same problem?
