I want to change my anti-freeze, but I can't find a drain plug anywhere, or otherwise, find a way to simply pull a hose and drain the radiator and cooling system. I looked under the car to find a drain source, but could not find anything. Please help!

There's a plastic petcock on the back side of one of the radiator tanks. DON'T OPEN IT, EVER! The tank will crack where the rubber o-ring seals against it, and you'll have a leak that will require radiator replacement. Just loosen the clamp on one end of the lower radiator hose and pull it off.

Are you going to flush the system with water, or just throw new antifreeze in it?
