how do i drain the cooling system on a 1998 vauxhall corsa 1.0litre petrol?

when water is cold open the coolant filler cap.locate the bottom hose on the radiator ,place a bowl under the hose and loosen the clip fastening the hose to the rad.pull off hose.you can then flush most of the system using a hose pipe.
