Does it return to normal after a few seconds of engine running?
Mine shoots to nearly red after its been driven for a lenghty period of time and restarted. However, after the engine has been running for seconds, it returns to normal.

Sender, gauge or wiring is shot. Factory Service manual should list the resistance tests for the sender and gauge, if they check out then it is the wiring. A quick test is to disconnect the sender and see what the gauge reads, then short the sender wire to ground and see what the gauge reads. I think normal operation is that disconnected=cold, shorted=hot.
