If it is not overheating then the temp gage or the sending unit are bad.

Why isn't the temperature gauge on my 2001 alero moving?
Idle the engine, remove the temp sensor wire on the engine and ground it. If the gauge does not move one can assume it has failed.

What is the idle temperature for a 1998 Chrysler Sebring?

How do you know if the thermostat is in an open position?
In cold weather, you'll notice that the engine temperature gauge registers only slightly or not at all, particularly if you're driving at highway speeds. You'll also notice that the temperature of your passenger compartment heater isn't nearly as warm as usual. Your car will show a temperature if you allow it to idle for several minutes. The heat flowing into the passenger compartment will be warm as usual. If your thermostat is open, the engine will rarely warm to a level you're used to seeing on the temperature gauge.
Why would a 1999 Nissan altima temperature gauge fluctuate and car is not overheating?
My Altima had that problem and it was the water pump going out. It started with temperature gauge was moving, but then it started leaking and finally the heater stopped being warm at idle.

How do you idle a the air and gas for a 79 Chevy carprice classic carburetor?
Install a vacuum gauge to a manifold source of vacuum (below throttle plates). With engine thoroughly warmed up and using a tachometer, turn engine idle speed adjustment screw down to 600 rpm. Start with one side idle air/fuel adjustment screw, turn it in slowly and watch the vacuum gauge. When the engine vacuum reading starts to drop, stop, then back out the screw until the engine just reaches its highest vacuum reading. Readjust engine idle speed to 600 rpm. Do this to the other side idle air/fuel adjustment screw then go back and do the first one again. After several times each you should be right on. Go back to the engine idle speed adjustment screw and set the rpm to factory specs.
How do you pressure test a power steering system?
You will need the proper gauge kit first. With the engine stopped install the pressure gauge with the shutoff valve in the open position. Start and idle the engine with the valve in the open position. Turn the wheel left and right several times to release any air bubbles and bring the fluid to normal operating temperature. With the gauge connected, close the shutoff valve for 5 seconds and compare with manufacturers specifications.
Why Car engine shake when AC is on at idle?
The engine idle may be set to low to compensate for the AC compressor starting up. Rev the engine a few times to see if it stops. If it doesn't, there may be a problem with the AC temperature signal or motor mount.
