I'm going to guess that it was the low coolant rather than overheat
that actually triggered the light on those occasions.  The low
reading -- dunno.  Pegging the gauge sounds like either the wrong
sender or a shorted sender.  If you actually short the sender wire to
ground, you'll smell hot stuff coming from the gauge within a few
seconds if the gauge is out on the bench.

Yrs,
