How do you drain coolant system on a 98 ford ranger?

To drain the coolant system on a 1998 Ford Ranger, first ensure the engine is cool, then locate the radiator drain plug at the bottom of the radiator. Place a container underneath to catch the coolant, open the drain plug, and allow the coolant to flow out. Additionally, you can remove the radiator cap to allow air in, which helps the coolant drain more effectively. Once drained, close the drain plug and refill the system with the appropriate coolant mixture.
