  That's the problem with most (all?) coolant temp gauges.  If you 
lose coolant and don't happen to see the gauge going up for the 
couple of minutes the temps are able to register, then the temp 
drops back dow as it conducts heat ONLY from the hot surroundings 
since there's not scalding coolant flowing past it as your engine cooks.
  I'd sat an oil temp gauge would be a good second gauge rather than 
a redundant coolant temp gauge for that specific reason.  YMMV
