Temp gauge all over the place

[KC96LSC]

Just trying to figure out what's up with my temp gauge. It wont stay in one place. I already replaced the thermostat, Not it. It blows hot air no problem. It just wont keep a steady temperature.

Any suggestions,

Greg

you probably have air in the system, did you filll it up through the cross tube?

It moves around from below normal (7:00 o'clock) to R (10:00 O'clock) and wil do it in a matter of seconds.

Sending unit? Worth a try.

Yes I did fill it up through the cross over tube. It was doing it before I replaced the thermostat.

Thanks for the help guys.

I like to think I know a little about cars then something common like the sending unit comes up and I go haa. Where is it and what does it do?

Thanks for the input.

either the sender, wires, or the gauge and the sender is cheap, easy and more than likley the prob

It communicates with the guage to give you the reading. I never changed it on the MarkVIII but I'm sure someone will tell you where it is. I could look if need be, the car is just sitting in the heated garage collecting dust.

i believe it is right at the base of the crossover tube.

There is a sender on the drivers side bottom of the crossover tube, that should be it. The other side is a sensor for the computer, if I had to guess.
