The belt routing diagram is on the jeep near the radiator. I can't remember off hand what it is connected to but near the bottom left side there is a bolt you need to loosen and then you can slide that pulley to loosen the belt. The diagram will show you where it is and also show you for both AC and no AC. If you look at the driver side of your giant fan shroud you should see a pulley of some sort on a slide.
