Where is the radiator drain plug on a 1991 mercury capri?

Answer 1

I found that you have to remove the plastic paneling on the underside of the front on the driver's right side of the car There should be about 4 screws. You'll find a black wingnut nearly touching the inner side of a 1.5" metal pipe. That's the radiator plug.

I had trouble re-threading the plug, and I found that the best way to overcome that is to use a screwdriver to push the radiator away from the pipe and then screw in the plug.
