Yup. I've seen that a number of times. I have not determined
_why_ but it's only a problem when the air is cold and the

Ideally the spot where the temperature sender is.
But it's not too critical, the hottest (non-manifold!) spot

I'm guessing a quick check of the gage would be to have someone watch the
instrument cluster and pull the connector off of the temperature gage, note
the gage reaction and then ground the gage connector and see if the gage
swings the opposite direction. You can do this with a cold engine and
