The drain plug is actually just a screw that requires a large Phillips head to remove. It is located on the passenger side at the bottom of the radiator. The best way to locate it is to find the tube that runs from the coolant reservoir to the radiator and look underneath where it hits the radiator. The plug is easy to overlook, as it just looks like a regular bolt. Make sure the engine isn't hot before you drain the coolant.
