Look under the radiator on the driver's side. There's a hole that's about an inch and a half in diameter that allows access to a plastic screw. This is the drain plug, you can remove it completely to allow the coolant to drain faster. Make sure the engine is not hot as coolant can be boiling temperature and will burn you if not allowed to cool down. Remove the radiator cap to allow air into the system so the coolant will drain faster as well.
