Temp gage has a mind of its own.

[JEEPTUBE]

97 xj 4.0 auto
When im stopped and not moving my temp gage reads normal at 210.
Then when i accelerate, it goes all the way down.
Could this be a faulty gage?

could be faulty , maybe loose wire.

Anbody else?
Maybe bad sensors?
Whats the one on the back of the head do?
Could it be my thermostat? housing? sensor?

Is it just your temp guage? I have a 98 XJ and I was having my airbag light come on and my speedo and tach. dropping to zero and my other guages freezing were they were.. all i did to fix it was pull the guage pod off clean the two connection terminals and that fixed it, i belive the 97s guage pod connects the same as a 98

97+ XJs only use the temp sensor on the thermostat housing. They no longer use the sensor on the back of the head for the gauge.

Right on thanks. That would explain why i couldnt find it back there.

Oh yah, it is starting to run rough now.
