Un most if not all Ford/Holden engines, the drain is accessed by removing the black plastis sheild under the front of the car, this will expose the draincock on the bottom of the radiator.

Depending on who made the radiator there will be a round drain plug on the L/H side looking from the front, otherwise you can remove the sensor, often the sensor is the easiest to remove, either is not a problem, just use a dab of pipe sealant on the thread and let it go off for about 1/2 hr befor adding coolant, make sure that you flush out the heater core as well.
