How do you change the antifreeze on 2004 Ford Freestar?

To change the antifreeze on a 2004 Ford Freestar, start by ensuring the engine is cool. Locate the radiator drain plug at the bottom of the radiator and place a container underneath to catch the old coolant. Open the drain plug to let the old antifreeze flow out, then close it once drained. Refill the system with a 50/50 mix of new antifreeze and water through the radiator cap, and run the engine to circulate the coolant, checking for leaks and ensuring the level is correct.
