1992 Jeep Cherokee water pump replacement

This doesn't have an automatic tensionier. Standing center in front of the car, look down slightly to the right. I believe it is on the power steering pump. You will need to loosten the set nut on the adjuster then there is a bolt that when loostened will loosten the belt. I believe it is a 13mm. Here is a diagram of the system with AC. I believe if you look at the 4.0L pulleys, it's on number 3.

Let me know if this helps.
