I can't remember exactly but its big (for a drain plug) somewhere around 17 or 19mm.
Under the bottom of theengine. It may be under your skid plate.
it may be one of the engines that dont have a drain plug exactly if it has a big plug on the bottom of the oil pan that the oil filter is in you drain it when you pull the filter (if the filter is built into the big plug on the bottom of the oil pan)
Look in the owner's manual on pages 124-125 It has a picture highlighting the drain plug in red. It's kind of hard to describe exactly where it is.
