While looking under the hood you may be able to identify six hard plastic devices, generally black in color. Three on the right and three on the left, somewhat evenly spaced. There are electrical connectors attached to them, with two, possibly three wires going to each, although the wires may be covered with plastic conduit. These devices are called "coil on plug" coils, they are on top of the engine, retained with a nut on a stud, and they extend down "inside" the engine a few inches. After unplugging a coil, removing any retainer clips that may be on the stud, and removing the retaining nut you should be able to carefully work the coil upward out of the hole. The spark plug will be down in the hole. Compressed air can be used if there is debris down around the spark plug, use eye protection and clear any debris from all plug holes before removing any spark plugs. While a spark plug is removed be sure not to get debris in the hole, that is direct access to the engine internals.

How to replace spark plugs in a 1989 jeep cherokee?
The trick to finding the spark plugs is recognizing the coils that are mounted above each spark plug i.e. you do not have a traditional distributor cap and spark plug wires.
30,000 miles is recommended for spark plug replacement on all Chrysler/Jeep vehicles, not just the Jeep Liberty. Not only are plugs recommended at 30,000 miles, shock absorbers are recommended as well. As a mechanic for the Chrysler/Jeep Corp., i can say with confidence that it is not entirely necessary to change plugs and shocks at the 30k mile mark. Basically, "If it ain't broke, don't fix it!" (however, i do recommend at least checking the plugs at 30,000 miles)
