The drain plug is located on the lower part of the radiator on the drivers side. It is a plastic wing nut style that faces the driver. You'll have to lie on the ground with your head in front of the drivers side front wheel to see it. It is difficult to turn for draining, and to tighten when finished draining. I recommend pulling off a hose to drain the radiator instead.
