In the center of the drum/pully there is a bolt (or nut, depending). This is what is locking the pully in place. Loosen it (no more than it takes to free it) befor turning the adjuster. Be sure to loosly snug it down to check your final adjustment and if correct, then you can tighten it all the way. (If it is too loose when the adjustment is set then the drum/pully will move when you tighten it and throw off the adjustment.)

Does a car have a pulley?
The engine usually has an idler and/or tensioning pulley as well as a few pulleys that use the power of a traveling serpentine belt to drive components such as the alternator, a/c pump, etc. Any of the pulleys that have one or more grooves that assist to guide the belt(s) are, technically, sheaves.

The idler pulley is attached by a 14mm hex head bolt. Although the pulley turns counter-clockwise, suggesting that the bolt might be left-handed threads, it is in fact right-handed. A 1/2" drive ratchet with a 14mm socket will loosen the bolt if turned in a counter-clockwise direction. Be sure and loosen the belt tensioner, located below the alternator, and loosen but not remove the other alternator bolts, prior to removing the idler pulley.

How do you replace a belt for a 1996 grand Cherokee jeep?
The serpentine belt has an idler pulley along it's path that has to be detensioned in order to easily put on a new belt. The idler should be near the top of the front of the engine. In order to loosen the tension you will have to get either a large socket (preferable) or a good sized adjustable wrench to put on the bolt in the center of the pulley. I believe that you turn this in a counterclockwise direction and it will ease up on the tension. You should have a sticker on top of the radiator that shows the routing of the belt. Put the belt around all pulleys per the sticker and then with one hand loosen the tension on the idler and slip the belt over the idler pulley. There is no tension adjustment other than what is provided by the idler pulley spring which is built in. After you do this once you'll find it to be one of the easiest repair jobs you can do and the belt is available at any auto parts store.
