I just spent a couple of PAINFULL evenings changing the belt and idler pulley on my 2000 Windstar (3.8). First, my pulley was held with a 1/2" REVERSE-THREADED bolt. Second...and most painful was that of stretching the belt over the pulleys. Absolutely forget about the 'special' tools from Autozone. The clearance wouldn't allow a socket to fit, the sockets were all metric, and the open-end attachments wouldn't stay on the bolt head. If the car was on a rack, then 'maybe' there would be enough room to torque from below...but definitely wasn't enough room from the top. I invented my own tool. I used a box end wrench on the pulley bolt. I tied a rope to the other end of the wrench and pulled it while my wife slipped the belt into place. This effort worked like a charm.
