How do you drain coolant from a 1999 Taurus?

To drain the coolant from a 1999 Ford Taurus, 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. After draining, close the plug and refill the system with fresh coolant, ensuring to bleed any air from the system if necessary. Always dispose of the old coolant properly at a designated recycling center.
