How do I drain the radiator on 2009 ford 5.4 engine?

To drain the radiator on a 2009 Ford with a 5.4L engine, first ensure the engine is cool and then locate the radiator drain plug, usually found at the bottom of the radiator. Place a drain pan underneath, open the drain plug, and allow the coolant to fully drain out. After draining, close the drain plug securely and refill the radiator with the appropriate coolant mixture. Always dispose of the old coolant properly.
