If I remember correctly the coolant light warning should be off when the circuit is shorted so that way the light would come on if the sensor gets disconnected or there is a break in the wiring. I think also that it is controlled by the LCM and not just a wire to the bulb on the dash. I would try shorting it out at the connector. You could also do some testing on the cooling switch to verify how the system works.
