I noticed a couple of times in traffic that my engine seems to be overheating. Even about a month ago when it was 20 below (celcius)!!! And now that the weather is starting to heat up over here I'm getting concerned. I've only had the car since september, but when I bought it I wasn't getting any heat from the heater so I had them change the thermostat. I read a little while on the board that there is 3 screws that need to be bled from the cooling system and if they aren't it could cause the engine to overheat? I tried to check if the fans where turning when it was hot but there pretty had to have a see!!!! If my hearing is good I could at least hear one turning, but exept for stiking my finger in there I'll have to find a better way to look a them. So if the fans seem to be running and I should have a new thermostat installed by a gm dealer (then again, these are the same guys who poured water on my opti!!!!), is there anything else that I can check?

Tnx,
Jason

 

you can hear the fans turning, but what i did if you have car ramps drive on the ramps and go underneath, and just look to see if there turning, and make sure yr system is bleeded, have the car runing and open up the screws until the air is gone, are you loosing coolant?

 

Nop, not loosing any coolant. But I can't remember if the problem started before they changed my opti or after, bc the would have had to replace the fluid after changing the opti if I remember correctly bc the opti is behind the water pump?

well what i would do is bring the car back to where you had it done, and tell them the problems your having ever since they worked on it, and see what they say, dont mess around with a overheating car dude

 

that's for sure, I've been turning the heater at full blast to keep the engine not too hot, but let me tell you it get's pretty warn in there

 

what year is yr car and how many miles are on it?

 

It's a 94 with about 75,ooo miles on it.

what i did and im sure lots of guys in here done it, is to the buy a programmer from hypertech, and a 160 thermastat, and reprogram the car to run cooler, among other things you can do with the hypertech, you might be able to find a used one to if you look for it

 

Air in the system can definitely cause the gauge to read high. Sometimes I feel like it is not indicative of the overall temp of the system, though. At any rate, check the bleeders to see if there is any air in the system when it is at operating temperature.

 

but I think that might of been the case when I bought the car, but it was running so cool I wasn't getting much of a heater

 

Them beeing on the top like that, to I try bleeding it when the car is running??

 

i live in philadelphia and have the power programm and have plenty of heat, and yes the car has to be running to build up pressure to bleed it

 

k, tnx

Yes, you can do it while running and the system is under pressure. Do it when the temp has at least reached normal.

 

K, I'll give that a try tonigh, I was just woried about doing that while it was at temp in case it would splash!
