1995 Camaro High Temperture?

Hi,





I have a 1995 Camaro Z28 and the temperture is quite high, almost to the red and sometimes goes back down.





One mechanic say it may be a cracked cylinder head and another mechanic says it's a common problem and the temperture gauge is off. The car never overheats and never shuts down. Which opinion is right? Thanks.

I had that problem years ago with a 1994 Camaro that I had. The found it to be something simple. The part that detects temperature was sitting on another part causing the temperature to red line.

Some mechanics use " test thermometers " to check and see how hot your cooling system actually is. From that basis and additional checks ( like an exhaust gas check of the cooling system ), one can decide if there are other problems.
Reply:Lets ask youself a question or two here.





Does the temprature come back down after the vehicle gets up to road speed or highway speed?





If the answer is yes, then it is either a cooling fan temprature switch, a burned out fan relay, blown fuse, or burned out fan motor. In any of these cases they will need to be replaced.





How long has it been since you have had your coolant serviced?





If you can't remember its time to have it serviced. Low Coolant levels can contribute to a vehicle running hot or over heating.





Think its a blown cylinder head gasket?





Open the radiator cap and start the engine. If bubbles come up in the radiator, then its probably a cylinder head gasket.

Then check under your oil filler cap, and look for "Bailey's Irish Cream". If you see a milky substance there, this is the issue.





Temp Gauges are a little different.





The only way to really see if its the gauge, is to have the vehicle professionally diagnosed. The gauge in the Camaro is not directly connected to the engine. The entire dash cluster receives its information through the vehicle's computer, (VCM, Vehicle Control Module). So this needs to be checked through the ALDL Connector, (Assembly Line Diagnostic Link), at the dealership.





This is one time, where GM has locked up the proprietary rights to their product, and the aftermarket machines will not get the correct information from your car's computer.





Since the car never overheats, my guess without seeing the vehicle, would probably be a faulty Temprature Sender for the gauge. But before going there, do the homework I gave you at the top of this.





You might find your issue is something you can repair yourself and save you a bundle of Gas Money!





Good Luck, I hope I helped you out!
