How do you remove the radiator drain plug on a 1998 Buick Regal?

on the lower drivers side of the radiator on the inside is a pet cock that you unscrew to drain the radiator You have to remove the black plastic air scooper on the bottom front of the car to gain access to the drain plug I have seen two types of drain plugs : one you turn by hand or with a set of pliers The other requires a 1/4" socket driver or rachet Turn ccw ~ 1/2 turn to open
