Temperature Gauge

You probably need a new sensor for the gauge. Find the sensor(usually on the top front of the engine if you have a v8 and has a red/white or white/red wire) and with the key in run, engine off, take the wire off the sensor and touch it to good clean metal on the engine to ground it. The gauge should be full scale one direction. Then take the wire off the metal and let it hang in the air, and the gauge should swing full scale the opposite direction. If it passes this test, the gauge and the wiring are good, and the sensor is bad.
If you buy a new sensor, make sure you do not use thread tape on it, and if you think you need sealer, put very little on just a few threads. The threads need to have good contact to the engine for the gauge to work.
