Engine coolant temperature

Asked by 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.
