XJ 4.0L Serpentine Belt Adjustment
The 4.0L engine does not have an tensioner for the serpentine belt. The adjustment is at the power steering pump. Just loosen the power steering pump rear mounting bolts, pivot bolt and lock nut and then loosen the power steering pump adjusting bolt.

Slip the belt on and tighten the adjusting bolt until you can push the belt in about one inch midway between the A/C and alternator pulleys. Then tighten the lock nut, pivot bolt and mounting bolts and that's it.
