Temp gage

i just swaped in a 350 in my 86 iroc and the teemp gage is always way high. i have had a computer reader on it and it says that it is running just fine the temp is right where it is supost to be but the temp gage is saying i am over heating when it warms up.

any ideas. (sorry for the spelling i aint good at it)

does the temp gage stay in the high range even with the engine cold and not running? If it does, replace the gage.

For some reason your response isnt showing up on the boards so I posted to let Nikon see he has one.

No the gauge works fine it is down when it is off. it moves slowly as the motor warms up but it just keeps movin till it is peged way past hot.

The grounds for the instrument cluster are near the steering column. Should be two black wires ending in one terminal lug.
