Check with warm engine and off by touching on your radiator vents whether is in all places same temperature. If not check whether you have air in the coolant which needs bleeding,or not good coolant circulation,caused either by clogged radiator,not good water pump,or faulty thermostat.By having these things it is the possibility the fan switch not getting the correct temperature to allow the fans to start. the last thing if everything is working,the possible is the fan switch itself.

SOURCE: 1999 plymouth voyager overheating cooling fan not working

Someone would need to check the fan relay for voltage and then jumper it to see if the fan will run.

Why is our 2010 cobalt still overheating after changing the thermostat?it has the 2.2 engine.the temp reaches 210 +degrees.sitting idled and the cooling fan is not turning on.The cooling fan only runs


was the thermostat installed the correct way round . Fans should start spinning at around 75degres c. Check coolant temperature sensor ( not temp. gauge sender unit) for operation. Have a flow test done on the radiator to check for blocked cores.. Have a compression test done to check gasket and for cracks.

Hi car is getting hot 2007 cobalt it went up to 220 then it comes back down. if i sit at a red light it climbs back up pretty fast. what is the normal temp. it never has gone up that high before.


sounds like the radiator fan is not coming on. possible cause is the cooling fan switch or the cooling fan relay. worse case senario is the cooling fan is bad

2006 cobalt overheating while IDLE


go ahead and have the thermostat and the thermostate switch replace since its giving you a sign, you don't want to have it overheat and leave you stranded or ruin the motor. the fans seem to work fine since you can hear and see it running.

A/C blows hot air intermittently


this is clear that your aux fan cooling your condensor is not working ,your a/c system is overheating and with speed you are forcing air through your condensor doing the job of the fan.

Engine cooling fan not coming on


It may be the fan itself. Try to find the plug going to the fan, it should be close to the fan and might plug diresctly into the relay. Use two jumper wires straight from the Bat one from the pos+ side and one from the neg- side and plug them into the two holes in the connector the fan should start WATCH YOUR FINGERS. If it starts its elec prob before the fan if not its the fan.
