Where is the coolant level sensor on 1994 Firebird?

If you have an LT1 its on the rear of the rad about 6 inches below the filler cap. its square and has a 2 wire connector pluged into the bottom of it. Your local auto parts store carries it for about 60 bucks, easier fix is just unplug the wires from it and the "low coolant" light on the dash will go out
