You should leave it plugged in over night. There are too many variables to consider like cooling system capacity, freeze point of coolant & ambient air temperature, to be able to let you know what the minimum of time it needs to be plugged in to reach full effectiveness.

Locate the block heater. Drain out the coolant from the rad and from the block if there is a drain there. There should be a screw in the center of the block heater. Unscrew it to loosen the block heater internal clamp. Use a pair of pliers and wiggle it free. As long as it is not plugged in, there should be no worry of damage. It is sealed with an o-ring.The element will have to be worked out as it goes into the block along the side.
