Belt size or go a different route?

if you go to a parts store with the information then they will be able to sell you the proper belt. if you have removed the AIR pump then you will have to try different belts until you get one that will work without rubbing on anything when its installed and running. if your lucky you may still have the belt routing decal under the hood either on the rad support or on the underside of the hood or air box. if not then the parts store may be able to help you with the routing.

The idlers may be located differently on a non ac engine versus an ac engine, or the pulley sizes may be different. I have seen many different pulley sizes for the alternator alone! I suggest taking an old belt or a piece of string and routing it where the belt should go. Measure the length and see if your parts store can get a belt of that length.

3.0L And 4.0L Engines

1. Disconnect the negative battery cable.
2. With the vehicle in neutral, position it on a hoist.
3. Remove the splash shield.
4. Rotate the accessory drive belt tensioner clockwise for 2001-2004 models and counterclockwise for 2005-2006 models. Remove the belt.
5. To install, reverse the removal procedure.

Serpentine Belt
All Navajo and B Series Pick-up engines utilize one wide-ribbed V-belt to drive the engine accessories such as the water pump, alternator, air conditioner compressor, air pump, etc. Because this belt uses a spring loaded tensioner for adjustment, belt replacement tends to be somewhat easier than on engines where accessories are pivoted and bolted in place for tension adjustment, such as the MPV. Basically, all belt replacement involves is to pivot the tensioner to loosen the belt, then slide the belt off of the pulleys. The two most important points are to pay CLOSE attention to the proper belt routing (since serpentine belts tend to be "snaked" all different ways through the pulleys) and to make sure the V-ribs are properly seated in all the pulleys.

Although belt routing diagrams have been included in this section, the first places you should check for proper belt routing are the labels in your engine compartment. These should include a belt routing diagram which may reflect changes made during a production run.

1. Disconnect the negative battery cable for safety. This will help assure that no one mistakenly cranks the engine over with your hands between the pulleys.
   

Take a good look at the installed belt and make a note of the routing. Before removing the belt, make sure the routing matches that of the belt routing diagrams. If for some reason a diagram does not match (you may not have the original engine or it may have been modified,) carefully note the changes on a piece of paper.

1. For tensioners equipped with a 1 / 2 inch square hole, insert the drive end of a large breaker bar into the hole. Use the breaker bar to pivot the tensioner away from the drive belt. For tensioners not equipped with this hole, use the proper-sized socket and breaker bar (or a large handled wrench) on the tensioner idler pulley center bolt to pivot the tensioner away from the belt. This will loosen the belt sufficiently that it can be pulled off of one or more of the pulleys. It is usually easiest to carefully pull the belt out from underneath the tensioner pulley itself.

1. Once the belt is off one of the pulleys, gently pivot the tensioner back into position. DO NOT allow the tensioner to snap back, as this could damage the tensioners internal parts.
2. Now finish removing the belt from the other pulleys and remove it from the engine.
   

To install:

1. While referring to the proper routing diagram (which you identified earlier), begin to route the belt over the pulleys, leaving whichever pulley you first released it from for last.
2. Once the belt is mostly in place, carefully pivot the tensioner and position the belt over the final pulley. As you begin to allow the tensioner back into contact with the belt, run your hand around the pulleys and make sure the belt is properly seated in the ribs. If not, release the tension and seat the belt.
3. Once the belt is installed, take another look at all the pulleys to double check your installation.
4. Connect the negative battery cable, then start and run the engine to check belt operation.
5. Once the engine has reached normal operating temperature, turn the ignition OFF and check that the belt tensioner arrow is within the proper adjustment range.

Hope helps (remember rated and comment this).

It depends on the engine size for the belt routing.

The symptoms you have described sounds most like you had a serpentine belt break or fall off the pulley system (rare but possible).That is a fairly simple job to replace the serpentine belt,whether you replace it yourself or have a professional do the job it isn't a costly repair, providing that is the only problem.There is a serpentine belt routing label under the hood, usually on the plastic piece that goes across the front of the engine compartment near the hood latch release.There is a spring loaded belt tensioner that holds tension on the serpentine belt(labeled on the routing label) rotate the tensioner against the spring pressure, rout the belt according to the routing label, then slowly release tensioner against the new belt and that should complete the installation.Hopefully that is the solution. Good luck !
