Tension is maintained using an automatic tensioner pulley assembly. The drive belt is tensioned by adjusting the position of the idler pulley, accomplished by moving the adjuster bolt on the idler mechanism.

Serpentine Belt Because serpentine belts use a spring loaded tensioner for adjustment, belt replacement tends to be somewhat easier than it used to be on engines where accessories were pivoted and bolted in place for tension adjustment. 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, and that the cooling fan cannot activate while servicing the belt(s). NOTE 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 diagram. 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.
2. For tensioners equipped with a 1/2 in. (13mm) 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.
3. 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 tensioner's internal parts.
4. 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.

Some vehicles have a idler arm which takes a 1/2 inch ratchet. You move the idler over to get the tension off the belt;remove,replace. A Dodge is probably like a jeep which has a movable idler. You loosen the hex head bolt in the center of the idler and loosen the bolt running along the side of the same bracket. This moves the idler down to take the tension off the belt. Remove it and make sure to route the new one in the same way. There is usually a diagram on the top of the fan shroud or radiator support to show you the correct routing. Hope this helps.

Somewhere under the hood, usually on the fan shroud or near the radiator, there should be a sticker with a diagram of the belt routing, 2001 may even be on the hood. On this diagram it will show a tensioner pulley and idler pulley and the approximate location. Most Fords use a 15mm or 16mm bolt on the tensioner, this is where you put a wrench to rotate the tensioner and remove the belt. When you turn the tensioner bolt turn towards the front of the car, there will be a lot of tension so pull hard.

Also Dayco.com offers a free online comprehensive serpentine belt reference tool - including routing diagrams and tensioner information.

Hi, when a belt comes off, it's usually because of a bad bearing in one of the accessories or idler pulleys, or maybe your tensioner spring is broken. Remove the belt and check all pulleys for spin and play. It is also possible you lost an idler pulley and the new belt routing is not turning the water pump in the right direction. Check the routing and look for a missing idler pulley. Let me know if you are missing the routing diagram.

Removal & Installation

1. Rotate the drive belt tensioner clockwise and remove the drive belt.
   WARNING Never suddenly let go of the tensioned idler pulley. The force of the spring pressure suddenly released may damage the idler pulley mechanism. Always release the spring pressure gradually.

To install:

1. Route the belt over the pulleys making sure all the grooves in the pulleys and the belt line up correctly. Refer to the accessory belt routing section of this manual.
2. Rotate belt tensioner clockwise and slip drive belt over idler pulley on tensioner.

If for any reason, the tensioner is crooked, replace it!!! Also, install the belt with the writing facing you like you are trying to read a book. This WILL (a trick I learned at Mercedes) prevent even a new belt from squeeling!!

There is an idler pulley that has tension on it. You need a socket and rachet to remove tension while you take belt off alternator pulley. If you do not have a diagram of the belt routing make one for when you replace the belt

OK.
If your idler pulley is bad then unbolt it and while you're at it replace the power steering belt.

Here you go.. I looked up the same belt you did, it should be right.

2 Loosen the hold-down fastener for the idler or generator pulley.
3 Pry the idler or generator pulley inward to release the belt tension and remove the belt.
4 Match the old belt up for size with the new replacement belt.
5 Observe the belt routing diagram in the engine compartment.
6 Install the new belt over each of the drive pulleys. Often the manufacturer recommends a sequence for feeding the belt around the pulleys.
7 Pry out the idler or generator pulley to put tension on the belt.
8 Pry out the idler or generator pulley to put tension on the belt.
9 Install the belt squarely in the grooves of each pulley.
10 Before adjusting belt tension, check for proper pulley alignment. This is especially critical with serpentine belts. Measure the belt deflection in its longest span. If a belt tension gauge is available, use it and compare the tension to specifications.
”If a belt is too tight, wear to bearings for the water pump, alternator, and engine crankshaft can result.”
11 Pry the idler or generator pulley to adjust the belt to specifications.
12 Tighten the idler or generator pulley fastener.
13 Start the engine and check the belt for proper operation.
