Unbolt it, pretty easy just one bolt in the middle of the arm...
I don't believe there is an idler pulley on that model, just a tensioner pulley
This means you have a 4.0L. There is no other way.....
Since There is no tensioner pulley you have to loosen your alternator.
I think it is the same as my 98 and you put a wrench on the bolt at the center of the tensioner pulley and push away from the belt.
Begin by loosening the tensioner pulley on the front of your 1996 Nissan Maxima engine. Slide the tensioner pulley to the right. The old power steering belt will become loose and can be removed. Put the new power steering belt on. Tighten the power steering belt by sliding the tensioner pulley to the left.
Near the top of the serpentine belt path is a belt tensioner; it is spring loaded and has a shinney pulley on it. Insert a wrench into this tensioner and pull against it and the tension will be released so you can replace your belt. I am assuming your question is about the serpentine belt.
See "Related Questions" below for a discussion regarding the serpentine belt tensioner and pulley. Pretty comprehensive coverage.
The serpentine belt you can look at the diagram in your engine compartment for actual routing. The tensioner mounts to the left side of the engine. You need to unbolt the whole assembly. Actually, the belt can be loosened by tightening the bolt of the tensioner pulley. When fully tightened, the pulley will act as a swivel.
There is no tensioner pully. The Power Steering pump has a moving bracket that adjusts the belt tension. It has a long adjustment bolt. You have to remove the air cleaner and housing to reach it successfully. Funny, mine has a belt tensioner pulley under the power steering pump, which is tightened by a long adjustment bolt. So does every other 1996 Cherokee I've worked on!

We recently replaced the serpentine belt on our 2003 Chevrolet Tracker. We were able to place a wrench (I believe it was 9/16") on the tensioner pulley and apply pressure so the pulley released tension on the belt. This however did no allow enough slack to install the new belt so we removed the idler pulley at the top center of the engine. With the idler pulley removed we were able to route the belt and with the tension released on the tensioner pulley, routed the belt under the idler pulley and reinstalled the idler pulley, then released the tensioner pulley and the belt was installed. Be sure to note the exact route of the old belt before removal so the new belt follows the same path. Hope this helps.
== # Loosen the idler pulley lock nut # Turn the adjusting screw to lower the idler pulley # Remove A/C belt. == # Install A/C belt over pulleys. # Apply a snug torque to the idler pulley lock nut. # Turn adjusting screw until proper belt tension is obtained. # Tighten idler pulley lock nut to 54 NÂ·m (40 ft. lbs) == The Poly-V generator/power steering pump belt is provided with a dynamic tensioner. == WARNING: DO NOT ALLOW DRIVE BELT TENSIONER TO SNAP BACK, AS DAMAGE TO TENSIONER AND/OR PERSONAL INJURY COULD RESULT. # Remove air conditioning belt. Refer to procedure in this section. # Apply a force in a clockwise direction to the tensioner pulley bolt # Remove belt. == # Install belt over all pulleys, except for the tensioner pulley. Refer to for belt routing. # Apply a force in a clockwise direction to the tensioner pulley bolt # While holding tensioner, position belt over tensioner pulley. # Slowly release force on tensioner. # Verify belt is properly routed and engaged on all pulleys.
