That sensor simply reads temperature, not level. Same goes for oil, it only reads pressure, not level. There's a reason they're called idiot lights, by the time they turn on damage has probably already occurred.

Coolant if leaking from the heater core will more than likely just drain out of the same drain that condensed water leaks from for the A/C.
