SOURCE: Temp gauge

the sender for the gauge is on the cylinder head near the spark plug if you unplug it the gauge should stay all the way cold then ground it out it will go all the way hot if that reads like that replace the coolant sensor

SOURCE: 2004 Chev Impala, temp gauge registers hot while

Unless you replace the water pump you are going around in circles. When you drive you have the natural air-flow thru the radiator and water circulastion will occur ie hot water rises cooler water sinks. If you havn't already damaged the cylinder head your lucky .White gooey residue on dip stick or oil filler cap will be an indication of this. Rust colored water indicated the adsence of inhibitors or coolant fluid and internal corrosion will be a consideration .

SOURCE: 2005 impala temp gauge is pegged above 260 f,

You may need a new stepper motor In The dashboard. Or you can replace the whole instrument panel. GM realized the problem and made a new version of the stepper motor so it shouldn't fail again if replaced. To replace each individual motor you will need to be handy with a soldering iron. The motors are pretty inexpensive.

My temp. gauge is sporatic. Sometimes starts in middle then guickly jumps way past hot mark to pointing straight down. But car is not overheating. Any thoughts?

There are two things that would cause this a bad coolant temp sensor or the guage is bad, this cars had alot of problem with the cluster, the gauges would do crazy things the most common would be the fuel gauge and temp gauge, i would start by replacing the coolant temp sensor and making sure the wiring to sensor is good and not frayed and touch any metal, hope this is helpful.

Why does my temp gauge on start go to 260 degrees and get stuck there

Wire or sensor is shorted. Unplug the sensor and see if the gauge stays low, if so replace sensor. If not, find short in the wire.

Freezing no heat with temp gauge going to 260 and red light on

You didn't say what kind of car it was, but with no heat and high readings on the gauge, my guess would be your coolant level. If that isn't the problem, then try replacing the thermostat. Other possibilities would be a defective temp sensor, or a bad electric fan on the radiator.

I have a 2004 Chev Impala and the temp guage went way past any numbers and wasn't hot. The speedo also stayed at 30 mph went the car is stopped. The speedo started working again when I shut it off and...

if you remove wire connection from temp sender unit and guage goes down then reconnect it goes up ? it is probably the temp sender unit is fault this is if you are certain engine/coolant system is ok and no indication of o/heating ?

Cooling fan problem

The electric fans on some vehicles dont stay on all the time. If the radiator is not burningyou then i would suspect the guage is bad. The engine would throw a code if the fan was not working properly, so im pretty sure that your fan is working properly. I hope that helps you out.
