Temperature gauge shows hot

The temperature gauge is showing hot when driven after several miles on my 1999 Pontiac Montana. It's had the water pump, intake manifold gasket. belt, and thermostat replaced plus radiator repairs. I'm still having the same problems. If I let the car warm up before driving it, it doesn't have this problem as much. When I reveve up the motor sitting still, the temp gauge goes back down. What kind of gasket does it need? Could it have other problems as well? HELP!!!!! It's driving me crazy!!!

    I'm taking it back to the mechanic today. I'll show him your answer. Will a different manifold gasket solve the problem? Thanks for your reply!

Will not restart
Sounds like vapor lock. This is when the fuel turns into a vapor before reaching the engine (it needs to be in a liquid form). This is usually due to high temperature from the engine and environment. I would have someone check it out.

My 2000 Montana gauge is showing that's over heating even when it's driven a short distance and when driven on the freeway it's not smelling like its over heating or there no steam coming
If the gas gauge does not work correctly and the temp gauge reads hot, you could have a problem with the instrument panel.
Both gauges get power from the same circuit, but each gauge is grounded by its own sending unit.
If the temp gauge is reading correctly, you could have air in the cooling system and it is not actually full of liquid coolant.

Water tempature gauge shows hot when car is cool ;and hasn't been driven
It sounds like the temp sender may be bad. This is the sensor that sends a signal to the gauge on the dash (as opposed to the engine coolant temperature (ECT) sensor that goes to the ECU instead.) It is located on the bottom front of the thermostat housing (which you will find if you follow the large hose from the top right of the radiator.)

Before replacing, make sure the connection is clean and secure, then check the wiring for any obvious failures.

1999 chevy vortec running hot
Change the coolant sending unit for the gauge. Usually this is different than the Coolant Temp. Sensor which is for the pcm. Maybe the sending unit is no longer functioning correctly after overheating. Of course, a scanner could show the temperature as recorded by the CTS, or you could use a hand held infrared temperature device to get a better idea of the true temperature.

The sensor for the fans is in the rad at the bottom. T-stat may be bad or the rad may be clogged. Cooling system needs attention.

Possible overheating, 2004 pontiac montana
Its definitly a bad reading, you would know if your vehicle is overheating, you can usually smell it right away.I would say its your temperature gauge sending unit is defective, check the wires to see if they are well connected or broken. ask a backyard mechanic for assistance.
