My temperature gauge on the dash is not reading what can the problem be?

If its only the temp gauge there could be a few factors. I had an '01 Impala 3.4. Once the code came up for the temp sensor. Changed it. Then the fans stayed on after engine shut off. Changed the relays. Then the temp gauge acted erractically. Belive it or not, I changed the thermostat, and blead the system. Then everything worked fine. Even the mpg increased on the highway! I read about this somewhere else. It did work. Many people would tell you to change the BCM. But if its only ONE gauge, that would fix for a while then go back to problem. Remember to bleed the system. These are little stems on top of hard lines.

Where should the temperature dash gauge needle be during normal driving on my 1998 Oldsmobile Intrigue?
Below the middle mark. if you have not removed the battery and the needles poped past the stops. this willmove the temp gauge and place it at a higher reading. replace dash to correct this.

I had the same problem with my 1970 mustang. First take the wire off of the Temperature sending unit (usually on the front of the block) and ground out the wire and see if the gauge goes up on the dash. if so it is just a temperature sending unit. They cost about 7 dollars.

Why does the needle on the coolant temperature gauge of a 1995 Saturn SL stay on the C?
The guage on the dash uses the ONE wire sensor... This is located in the block near the drivers side. Eric First check to see if you have coolant in the radiator. If there is no coolant you will not get any reading from the temperature sensor. If there is coolant then change the temperature sensor.
