Repair guides and support for the first generation Grand Cherokee ZJ, an upscale mid-size SUV built by Chrysler's Jeep division.
Looking at the routing diagram for the belt, I would say the one of (a) the power steering pump, (b) the alternator, or (c) the idler pulley is mounted on an adjustable bracket. Look for the mounting bolts that are going through a slotted bracket. There also might be a 1/2" square drive hole in whichever bracket swings, if so use use that (and a breaker bar) to tension the belt.
