How do you change antifreeze in a 1997 Ford Aspire?

To change the antifreeze in a 1997 Ford Aspire, first, ensure the engine is cool and then locate the radiator drain plug at the bottom of the radiator. Place a container under the radiator, open the drain plug, and let the old antifreeze drain out completely. After draining, close the plug, and refill the radiator with a 50/50 mix of new antifreeze and distilled water. Finally, run the engine with the heater on high to circulate the fluid, check for leaks, and top off if necessary.
