You probably have air in your cooling system. Is your otterstat above or below the coolant pipe? Early models had it on top of the pipe, and ran the risk of getting air trapped in it, not allowing any of the hot coolant to actually hit the sensor and trip it. If it is below the cooling pipe, then it is possible that you dont have any coolant in that line in which case you should flush, refill, and bleed the whole system. Sounds like everything else is good though. I doubt the gauge is faulty.
