Near the thermostat there's a couple temperature sensors. The sender for the dashboard temperature gauge is smaller and it has only 1 wire. Check that wire for having damaged insulation, shorting to ground.

If that wire is shorted to ground, fix the short, repair the insulation, whatever... But the shop manual has warnings that this can damage the gauge in the dashboard if you allow it to be shorted for long.
