check the resistance of the coolant sender with a multimeter and compare
your values to the ones in the manual.  additionally check the resistance
between the case near the sender and ground on a chassis ground point.
resistance should be very low here, if not clean up or redo ground
connections to make it so.

the problem could be with the temp gauge circuitry in the instrument
cluster.  they go bad, i replaced mine about a year ago and did a bit of a
right up for the archives.  additionally mark drillock has written about
this at length.
