Dude it's easy. Find the idler pulley and push down to release the tension. There are a bunch of write ups for this if you hit the search engine. I think I used explorer 4x4 and found what I needed

The idler pulley next to the alternator is spring-loaded, insert a ratchet wrench into its square opening & push against the spring to release tension on the bolt.

Be aware that cracks running length-wise around the serpentine belt are the types of cracking that indicate the belt needs to be replaced. Cracks that go across the width of the belt, across its grooves, are 100% normal & will show up soon after even a brand-new belt is installed.
...Gone wheeling, back Sunday night.

When you have a choice, buy American.

Don't know when they changed, but my "99" has an idler pully below the steering pump with a long threaded tensioner bolt to loosen it. You have to loosen the pulley bolt slightly then back off the tensioner bolt.

It's a pretty straight forward job. I changed mine out a month ago. I also had to get a new tensioner pulley, and idler pulley at the same time. Save your old belt as a trail spare as well. Good luck.

Be sure to save the old one as a trail spare, you'd be surprised at the number of people who fail to do this.
