Where is the engine coolant drain plug on a 2001 Buick century?

It is on the drivers side on the bottom corner facing the engine. It is small and difficult to find. I used a mirror to find it. It has two ears to twist but forget that. If you look at it with a mirror, you will find it it will accept a 3/4" inch socket for a 3/8" ratchet 1/2" rachet might work. Mine is draining very slowly as I type this. Stupid GM engineers. Leon
