Where is the idler tension wheel on 1996 Mercury Sable?

if you mean the idle pulley, as we call it, i dont know if we're talking about the same thing here, but if we are, it is the pulley in the farthest back of all of them. its also the smallest other than the one to the air conditioner, which is in the bottom front.there should be 6 pulleys on your car. a haynes manual should tell you what you need to know. they have picture diagrams that are easy to follow. and you can pick one up at your local parts store for about 14.99 (depending on your state)or library.
