Over Heating? Had Everyone Puzzled
I have a 2005 Chevy cobalt. I purchased the car with low mileage on it and like to think I properly maintained it through out the years. At this point how ever im not happy with my little blue friend.
I have gone to multiple mechanics, including 2 gmc dealerships.
here is my 2 year long story.
My car over heats. not always, it really is weather pending. on warm days, it takes sometimes less then 15 mins to get it self up to 100 degrees. My car has always hovered around 87-89 degree range, sometimes, up to 90. by 105-106, it stalls.
There is no dash lights indicating anything. I have no coolant leaks or low on coolant, thermostat is working as it should, rad is working fine. I have no problems with my heat, I have no problems with my AC either. In the winter time, the car runs perfect, never getting hot.
I have one mechanic, ( not gm) thinking that it may be the computer. Something about the relay is not receiving a signal from the computer to turn the fan on. This to me makes sense to a certain degree, how ever, this is the ONLY issue with the car, it over heats. He pulled the slow speed relay out for the fan to keep the fan for the motor running all the time, and the car ran like a charm, no issues what so ever! But I clearly cannot drive around for the rest of my cars years like this.
I have a second mechanic telling me that its the battery.....
Gm is telling me that its the water pump and want me to pay almost 600.00 to fix it. This to me does not make sense and I have heat, I have air conditioner in my car, and for what ever reason, when I turn on my AC, the compressor turns the fan on bringing the car back down to its normal temperature.
I have no idea what to think here. I know I should be taking GMC dealership advice seeing as they made the car but for someone who has with a previous car replaced a water pump, doesn't seem like that could be the issue.
The second GMC dealership told me its nothing and its ok for the car to get hot like that. (someone clearly has no mechanical skills and should not be working at a dealership)
Im not sure what else to do, or how to go about finding out the issue with the car. I have spent so much money trying to figure out whats going on that im almost at a situation where I don't want to, im ready to walk away and get my self a pretty Elantra! Has anyone else had this issue? or know what the problem might be? any type of insight would be amazing! Thank you in advance.
