I just got through removing the belt from a 96 and found it different then my 92 model Jeep.
If you don't have the specialized tool for reaching the idler pulley that is below the power steering pump. I found it easy to remove the electric fan and then reach it with a socket. 15mm it is, btw. the electric fan is held on with two little bolts on the top that usually hold down the line going to the overflow bottle. You will need to disconnect the connector to the fan as well, as there is not much slack. The long bolt that is at a angle and goes behind the power steering pump is the adjustment. Once the pulley is loose you will see that loosening this bolt allows slack in the belt. Don't forget, that you need to tighten the daylights out of the belt to keep it from squeeking!
Seems that a lot of people go ahead and replace the pulley while they are in there, I am debating this with myself right now......will decide tomorrow when I buy a new belt!
Good Luck!
