2005 Pontiac GTO Question: Overheating



gtolover05, Laveen, AZ, July 22, 2009, 21:49

Car temp gauge reads over heating when electric fans kick on no signs of water leak or actual over heating symptoms seems to come and go and the radiator never boils over or shows signs of over heating... What could the problem be? concerned goat owner

    I wonder if the thermostat is sticking or the temperature gauge is just inaccurate. A repair shop will use a non contact inferred temperature gun to detect the actual temperature around the radiator, thermostat housing to see the real operating temperature of the engine. No coolant loss is a good signs, cooling fans coming on also good. Using a non contact infer-red temp gun to verify running temperature should be an easy in expensive test.

    Did you find out why your GTO was overheating? I also have a 05 GTO that says it's over heating after it idles for a while like at stops signs or heavy traffic. I rev the engine once and it goes down. Thanks for the help! My email is jbuck20022000@yahoo.com
