How do I change antifreeze in your ford 500?

To change the antifreeze in your Ford 500, start by ensuring the engine is cool. Locate the radiator drain plug at the bottom of the radiator and open it to drain the old antifreeze into a container. Once drained, close the plug, then refill the radiator with a 50/50 mix of antifreeze and distilled water. Finally, run the engine with the heater on to circulate the new coolant, and check for leaks.
