After radiator has cooled down remove radiator cap. In the center underside of the radiator is a drain plug unscrew it and drain until all coolant is empty. You will have to locate the bleeder screw in the head in order to drain the fluid in the head and not just the fluid in the radiator and lines. The screw is near your throttle body on the head of the engine (top and center). It is hard to explain where without pictures, but I suggest getting a simple Haynes or Chilton's manual. For simple things like changing coolant they really help and the money you save by doing this yourself once will pay the manual off.
