There's usually a plastic plug on the bottom of the radiator on the passenger side. Unscrew the plug and put a pan under the vehicle. Pop the cap off the radiator to let in more air. That should be it.
Found plug below transmission line but no slot to unscrew it
If you have a big plastic belly pan under there, you will have to remove it to get to the plug. Awesome design huh?
If no drain plug remove bottom radiator hose.
