Engine coolant temperature
Asked by Matthew May 05, 2016 at 05:57 PM about the 2010 Chevrolet Cobalt
Question type: Maintenance & Repair
I'm concerned about my engine. I own a
2010 Chevrolet Cobalt LT sedan. Fort the
last week or so, my engine fans have been
running for a few seconds after the engine is
shut off. Recently my display has told me
"cooling mode on". I checked the coolant
temperature, and in operation, it hovers
around 250 F. Is the temperature OK, and
why are my fans running?

if you are sure your coolant level is full, keep a close eye on your temp while driving. you might just need a new thermostat. also, it isn't that unusual for cooling fans to do that.
I agree. I don't think you have a problem, but do check your coolant level and top it up if its low. Also the coolant should be changed from time to time, so it may be time to take it in and get that done. That won't be the source of a cooling problem, but its an opportunity to have your cooling system pressure checked and refreshed before you get into the serious summer heat.

My 2005 cobalt runs between 190 - 210 degrees Fahrenheit this car has been a rock for me I'm usually a Ford man but a Chevy Cobalt will take a beating
Did you ever find out the problem? I have same issue we have replaced just about everything n some things twice
What are you trying to fix. The conclusion of this thread was that there was no real problem.

I have a Chevy cobalt ss and it says I have 180F but I just put in a refrigerate and i think it dropped should I put more or are my lines ripped?
I'm not totally clear on what you're asking but I'll try to help. If you're operating temperature is around 180 you're fine. The main thing now is to make sure the cooling system is full. That's a simple case of filling the reservoir to the Full line. If the system has been drained or was extremely low its possible to have air trapped in the system, which usually causes overheating problems. There is a bleeder valve near the thermostat housing that you can use to release air that may be trapped in the top part of the cooling system. if its a supercharged SS there is a second cooling system to cool the intake air. Make sure it is topped up too and when the engine is running you should be able to see the coolant in that system flowing. If the coolant isn't moving the pump may not be working. I hope this helps.
