overheating and Fix.. GM is wrong!
I have been dealing with my car for the past month overheating to about 225-230 in stopped traffic. It never did this last year. It always ran around 190-192 respectivly maybe 199 in traffic. Fans kick on fine before and after. Car suddenly started to reach 225-230 in traffic and would take a great deal of time to cool down. Normal Highway was running around 196-199 which was hotter than last year. Finally yesterday the car ran 232 and I couldnt get it to go down very quicky at all even on the highway. It finally went down to 183 which is obviously the thermostat sticking. I brought the car to the dealership last week, they said this was perfectly normal. Obviously its not good for an aluminum head to keep changing temps from 183-232. Its going to cause the head to walk and will blow a head gasket for sure if it continued. So dealership would not replace my thermostat under warranty or for anything at all telling me its normal. Today I woke up, went to advance auto, bought a the OE 180 degree thermostat, installed it within 10Min. All you need is a 10MM socket and wrench and 2 bolts later, thermostat changed. After all of this the car now runs 190-192 steady about 194-196 in traffic. So GM is full of $hit and I had to pay 20bucks for a thermostat that they would not replace. So just an FYI, if your car has this issue, change the thermostat. Thanks Everyone hope that helps.

You should take the old thermostat down to the GM and throw it at the tech that said it was normal.... when he asks why you threw it, tell him it's normal to throw things at stupid people...

Yes I will do some How to Pics for this. Its extremely easy! And yes GM told me they want to see the thermostat that I took out, and I will be sure to tell them what F-in Idiot they are. $20 bucks for a Thermostat Vs. $2000 for a valve job and head work after it blows up. Hmm whats better for them? Idiots!

GM was right. there's nothing wrong with that. in traffic it's not unusual for the temps to get WAY hotter than when standing still. the fans kick on around 230 and cool it back down. as long as it's not ALWAYS over 230 it wasn't a problem at all. these engines fluctuate like that.

you're correct, it's nothing to worry about. the original poster just got extra worried. there was no need to change anything. i got worried the first time mine went up to about 220, since it was normally under 190. after doing alot of research on it, i found that these engines run hot, and it was nothing to worry about.

I dont have stage 2 but almost never see temps above 200. i have to sit at a light for a looong time to top 200.
maybe the thermostats are really inconsistent from car to car?

This is awsome.. I love the debates we have in here... So " thought " do you agree or disagree? But let me rephrase a few things, I agree that the temps should rise in traffic. Its obvious with no airflow to cool the coolant, but my findings are based on what the car did last year in the heat and the fact of 50 degree fluxuations all the time, on a aluminum head is bad and that now it is normal again after the change out.

nice!!
see here's the thing, to actually know if it's a problem or not we need more info. i agree, if it's fluctuating 50 degrees every 10 minutes, that's bad. but, if every now and then in heavy traffic it goes up to 220-230, that's completely normal. if in one trip it goes 180-230-180-225-180-230 then that's not normal.
but, the ecotec runs hot. that's not an opinion, that's a fact.

yes that is exactly what it was doing.... 192-199-230-232-187-199-230-232-190-194 over and over and over, expecially in traffic. This was a everytime i drive the car occurence. Since the thermostate change its 189-192-194-192-190-192-194-190 much better even in traffic it never got no where near as hot, and defintely not over 200... So obviously that part was screwed. I see what your saying though, and I should have explained it better.
