Temperature Issue 92 Camaro

Have you replaced the temperature sensor for the gauge? Maybe it's not really running as hot as indicated. - Gary

I had a 85 Chevrolet Caprice that after shutting down, would start to boil over into the overflow. She always ran a little warm, but never to the point of over-heating. Is this happening to you? Is coolant getting close to the boiling point? If not, I would have to agree with Gary that you may have a bad sensor.

I have same car and same engine and it was doing the same thing, I put a 165 degree Thermostat in it it still runs at 190 according to the temp gauge, and I got the radiator flushed, not sure it that will help you or not but it fixed my problem.

Chevrolet had a bulletin for camaros with temp guages being out of calibration as well as I can remember you get a 10 ohm 1/2 watt resistor and cut the wire going to the coolant temp SENDER and splice the resistor in there this is supposed to bring the guage reading down to match the actual temp of the coolant

NOTE: Be sure you have the temp sender and not the sensor as 10 extra ohms there would certainly cause performance problems

The number is #43-81-07 but it is for 93-94 camaro/firebird with specific vins check your vin before doing this procedure

I have an 85 IROC-Z, it always ran hot >220, the fan is rigged to run non stop when the car is running and I still cannot use the AC long. Recently it overheated and now I cannot run longer than 15 minutes without overheating.

What I have done already:

• Checked the water pump, no movement, no noise and the water is moving rapidly in the radiator.

• I replaced the 190 thermostat with a 165.

• I replaced all the hoses (they were getting worn anyway).
• I replaced the antifreeze when I back flushed the system.
• I replaced the 5 groove serpentine style belt.
• There is no oil in the coolant, I verified that during the back flush with clear water, there is not water in the oil I changed it and inspected it very closely indicating the head gasket in fair condition.

Is there any chance that compression is being forced into the water jacket and no fluids are being exchanged. This would cause air pockets and the car would overheat fast. I have noticed that even with no thermostat the up radiator hose is very rigid after a short time running.

Thanks for your help. Bryan
