    Has anyone ever had an overheat problem where the heat gauge does not go out of the normal operating range?

    I just recently purchased a 2000 GTP 3.8 supercharged and was told that it needed the intake gasket replaced as it was getting air in the system. Pulled the intake and the gasket was totally done, pulled the heads and had them redone, replaced everything including t-stat, radiator cap, refilled the coolant, bled the air out. Runs like a champ but... yesterday car started running real bad, pulled into driveway and smelled like the belts were melting. Fans were running, temperature gauge was normal (185) checked the coolant level and it was 1.5 gallons low.
    Is it posible to overheat and it not be detected by a working temp gauge? If so were would the trouble be lurking?

    Thanks

    SW...

    If your eating coolant I highly suggest draining the oil and seeing if it is a milky color. If so...something might not have sealed up correctly with the Lower Intake Gaskets and your just dumping coolant into your motor...which isn't good at all.

    My question to you when you re-assembled it...were the head gaskets put on correctly and were the LIM gaskets RTV'd? Overheating issue on other platforms always tends to let me lean towards bad head gaskets...and since these never go bad on this platform...I'd say don't worry about it...but since they were just re-done...something might have gone wrong.

    Above all...I wouldn't be driving it until you figure out where all this coolant is going.
