The easiest way to flush, if radiator is left in the vehicle, is to have the car at normal operating temperature, open the radiator drain, and put a garden hose into the cap opening. Turn it on till as much water enters the radiator as is leaving the drain. Run the engine as you are flushing, and run it till the water runs clean out the drain. Then shut off and refill with a 50-50 mix of water and antifreeze.
If you take the radiator off, you could run the hose into the bottom hose fitting and let it drain out the top hose fitting or the radiator fill neck.
