and im looking at a 1994 camaro. 5.7 auto... what kind of problems are with them and what should i look for when i drive it tommrow?

[Chevyracincamaro]

basic car stuff, im sure you know, these cars do not hide problems well. look over the car for your standard stuff: rust on the chassis, body damage, listen to the timing and the valve train, get all the repair info...

R U HOT

[Lotus49]

yes, very. come to me...

their should be 2 temperature sensors one tells the gage how hot it is the other tells the computer how hot it is. if your gage reads hot but your not boiling over it is probably the sensor to your gage pull the wire off of the sensor and ground it your temp gage should go all the way to the hot side. next check the sensor to the computer do not ground it. check it with a volt meter I think it should read 5 volts

hmm i had a problem like that in a dodge daytona i used to own.

i rewired the fan to a swich in the interior, and all was good. i dont know if it just wasnt turning the fan on on the highway or what, but that did the trick for me.

like said above, that is something totaly opposite of what would/should happen. wierd

Make sure the plastic front air dam is still on the car. I have been a Gm dealer technician for about 20 years and I remember when those cars were new we had to install the air dams during the new car service. If you drive the car at highway speeds with out the air dam it will overheat because not enough air will get to the rad. If it is still there I would start by checking the timing it can cause this if it is really off.

After I posted this I see your other post that you figured it out, I thought that was your problem.
