I have a 06 Chevy cobalt with coolant temperature problems.

Customer Question

I have a 06 Chevy cobalt with coolant temperature problems. While driving the temp will sit around 205-220f however when sitting at a light or when idling the coolant temp just continues to climb, I've seen it get as high as 250f. At that point I turn it off to keep the causing engine damage. I've heard the coolant fan kick on however it sounds like it turns off with in a few seconds. Is it the fan that I need to change or could this be a thermostat or fuse issue?

Hello. My name is ***** ***** I will be helping you today.

It sounds like its probably the fan but without testing I cant say for sure. Do you have a multimeter?

Customer: replied 5 months ago.
No I do not, if I get one what should I test?

If you get one I will walk you through testing.

Ok I have the multimeter what should I test to confirm its the fan
Expert:  Kavey replied 5 months ago.

OK there is a black and a blue wire at the fan motor connector.

Touch one of your test leads to each of those wires.

Check the voltage when the fans turn off. Let me know what you get.
