How do you drain a Lincoln navigators radiator?

To drain a Lincoln Navigator's radiator, first ensure the engine is cool and then locate the radiator drain plug at the bottom of the radiator. Place a drain pan beneath the radiator, open the drain plug, and allow the coolant to flow out completely. Once drained, close the drain plug securely and refill the radiator with a proper coolant mixture. Always dispose of the old coolant responsibly.
