How do you drain coolant of a 2000 jetta gls?

To drain the coolant from a 2000 Jetta GLS, first ensure the engine is cool, then locate the drain plug on the bottom of the radiator and place a container underneath to catch the coolant. Open the drain plug and allow the coolant to flow out completely. Additionally, you can remove the radiator cap to help the fluid drain more efficiently. Once drained, close the drain plug and refill with new coolant as needed.
