CAUTION: DO NOT ATTEMPT TO DRAIN WHEN HOT!!! Let engine sufficiently cool first.

You do not have to remove it. There is a petcock on the bottom of the radiator that looks like a thumbscrew. Climb under the vehicle and look up near the tanks on the radiator near the sides and you will see it. Take the cap off the radiator and open the petcock. Just remember that antifreeze is poisonus and cannot be disposed of in the open.
