How do you drain coolant from 2007 Hyundai sonata?

To drain the coolant from a 2007 Hyundai Sonata, first, ensure the engine is cool and then locate the radiator drain plug at the bottom of the radiator. Place a container underneath the drain plug, open the plug carefully, and allow the coolant to fully drain out. After draining, close the plug securely and refill the system with new coolant as needed. Always dispose of the old coolant properly, as it is toxic.
