Having trouble getting the belt to the alternator. there is no slack.
If one of the idler pulleys has a 1/2 " square hole in the end , place a 1/2" bar in it and lift /press the pulley against the spring tension and install the belt correctly then let the pulley come back to position
Use tensioner $4 use 1/2 inch breaker bar or ratchet to move in in. it spring loaded

There is a diagram under the hood showing how
the belt fits over all those pulleys. It's either on the
hood itself or on the chassis near the hood pin release pin.

Some are actually spring loaded and others just have a slot that allows for adjustment.
Either one of those types should be visibly different.
If the belt is not used for cam timing, the adjustment may be done with one of the accessory items such as AC compressor, the alternator or the power steering pump.
In this case, the adjustable device will have one pivot bolt and another that goes through a slotted area to allow the device to 'swing' for adjustment.
The pivot bolt should be only a little loose so one can just barely move the adjustable device, while the adjustment bolt should be free while adjusting.
This may help not losing the adjustment after having set the belt tension correctly.

Under the hood on the radiator support bracket is a belt routing diagram.
To remove/install you will need a belt tensioner prybar.
Remove the belt tension by prying back on the tensioner using the nut in the middle of the black pulley in the following picture.....
It is pretty strong - you will need a really long handled wrench - or most autoparts stores sell/rent them.
Take not of the way your belt runs over/under pulleys.
Without more info on your truck.... engine size, options etc... we cannot provide an accurate routing diagram.
The parts store that has your belt will also supply you with the routing diagram.

Click on the following free direct Link. It has the correct Serpentine/Drive Belt Diagram for your 2004 Ford Freestar. You either have the 3.9L or 4.2L V6 Engine. I am not sure what Engine options (AC/No AC, etc.) you have. If this Diagram is not correct: check on the underside of your Hood for the correct Belt Diagram. However the below "How To" remains accurate.

"HOW TO":
Standard Rules to Removal the Serpentine Belt with an Automatic Tensioner:
1. Find the Tensioner(s). (See Diagram on Link)
2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (on the Pulley or Arm Base) OR the OPENING (3/8ths or 1/2 inch square opening) rotating the Tensioner Pulley/Arm - moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
3. Remove the loosened belt off one of the other more easily accessed Pulleys.
4. DO NOT quickly release the Tensioner, but gently allow the Tensioner to rest in its closed position.
Standard Rules for Installing the Serpentine Belt with an Automatic Tensioner:
a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.
b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right.
c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley.
d. Using your other hand - Pull the Belt up and over the Last remaining Pulley.
e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them.
