What kind of water temps (F) are you 3400 guys seeing under different conditions. For example:

My car:
195 while driving
200 while driving on a hot day
205 (max) in traffic

My buddy's car:
230 while driving
240 while driving on a hot day
260 in traffic!!!

The dealership told my friend that this is normal for GA's, but if I ever saw temps like this I'd start to worry.

So what do you guy run at?

:wtf THAT IS NOT NORMAL !

Have a read of thread: what additive should i use to keep car cooler? (http://www.grandamgt.com/forum/showthread.php?t=51811)


From: What Temperature Engine Cooling Fans Come ON At (http://www.grandamgt.com/forum/showthread.php?t=21601)

The PCM commands Low Speed Fans ON under the following conditions:

The engine coolant temperature exceeds approximately 106C (223F).
The A/C refrigerant pressure exceeds 1310 kPa (190 psi).
The vehicle is shut off when the engine coolant temperature is greater than 140C (284F) and system voltage is more than 12 volts. The fans will stay ON for approximately 3 minutes.



The PCM commands High Speed Fans on under the following conditions:

The engine coolant temperature reaches 110C (230F).
The A/C refrigerant pressure exceeds 1655 kPa (240 psi).
When certain DTCs set.
There is no reason why your friend's GA should be running 230F & up all the time.
That would mean the high-speed coolant fans would be on all the time.

I don't think I hear my high-speed coolant fans come on anymore; except times if the AC is ON.

At those temps, his oil must be getting a work out :nono:

Get him to go to another GM dealer.


PS: the V6 engines have a 195F thermostat & the 4-cylinder engines have a 180F thermostat.

260 is overheating and on the brink of warping your heads irrepairably.

Thanks for all the input guys. He is going to another dealership to get it checked out again. I think the first dealership was blowing him off becase he just bought it used from them and they don't want to pay for it. BTW, it's a 2003 with the SC/T hood, so I suggested he remove the hood scoop inserts to help keep the engine cooler until he gets it fixed.

Did you know if his thermostat is stuck closed? If so no coolant is flowing though the engine which is probably leading to those ridiculous temps.

He originally went to the dealership to get the thermostat replaced, but they were telling him it was fine. I'll let you guys know what he finds out at the second dealership.

I had nearly the same problem with my last car - '88 Bonneville.
Temp guage went up about 3/4, then would stay 2/3-3/4 but not overheat. Thermostat was sticking.
Running that hot will also eventually fry your tranny fluid, as it did mine.

Had the opposite problem in my GA, engine would only run ~170-180, would only hit 200 in stop & go traffic on a warm/hot day. Of course the dealer tried telling me it could be 500 other things. I told them just change it anyways, and it fixed the problem.
