How do i replace serpentine belt on 1997 jeep wrangler

It would if there are 2 belts or more present. If it's a one belt setup it has one tensioner. Are you having trouble replacing a belt. Most auto parts stores will print you a belt diagram free of charge. Hope this helps. Chris

taking a shot in the dark most common is 4.0liter with a/c but let me know if different .

loosen the bolts that hold the power steering pump to the bracket, then turn the transverse bolt under the pump to adjust tension.

Go the other direction. It takes a breaker bar to move the tension arm.

Look for the belt tensioner. On some models, all that is required is to use a socket and ratchet to lift the tensioner. SInce your vehicle is a 98 model, the tensioner should be an automatic type that just lifts up. If that is the case, then lift up the tensioner to remove and to replace the belt.

Before installing the new belt, rotate the tensioner pulley until it's in it's "free arm" position. This will enable you to get the belt routed around the other pulleys saving the tensioner pulley for last. Once on, rotate the belt until the tensioner pulley takes up slack. It should lock into place once the engine is started. Best of luck and please post back either with any questions or to rate this solution. Thank you.

Should be the pulley underneath the power steering pulley. Loosen the nut, then back the bolt down the loosen the belt, tighten the bolt to tighten belt.

you need to loosen the alternator bolts then turn the bolt under the alternator to relieve tension on the belt
