There is a set of holes on the driver side (left side) of the roll stopper mounting (most people call it a motor mount). Look ta the bottom of he radiator for a red or green color drain plug recessed into bottom of the radiator, and the associated hole in the frame to pass a #2 or #3 phillips driverthrough to the plug...

BE ADVISED, the plug is soft plastic, and there is a black rubber gasket that MAY or MAY NOT stay on the plug, so keep your eyes open.

The plug will unscrew, and let it rest on the frame, not enough room to get it out usually, I fold up a shop rag and stuff it between radiator bottom and frame next to the roll stop mount to keep coolant from running along frame to opposite side of car and make mess on floor.

Whe you install the plug, just snug it good, DO NOT apply major torque, you'll break the head off the plug.... co-worker did that to me 1 time, as he needed the drain while I was away from the car, so he installled the plug and broke the head off... running joke now that he will offer to install the plug for me once in a while..
