There should be a 1/2 inch square slot to insert a 1/2 inch drive ratchet or breaker bar and lever the idler assy so as to release the spring tension.

Having trouble putting serpentine a/c belt on 2000 chevy silverado with 4.8 I cannot get it around pulleys

if you are using the tool to release tension of the belt tensioner and you are putting the belt on the pulleys in the right sequence as shown on the under hood decal and you still can`t get the belt on then you have a belt that too short for the application either the wrong belt in the sleeve with the right part number or it`s just plane too short of a belt

The belt has tension applied to it from an idler pulley arm. you need to release tension by using a socket and ratchet on the nut on the idler pulley. Release tesion and slide belt off . Make sure you have the diagram for serpentine belt. it is usualy under the hood. If not make a diagram yorself before removing belt.

How do I loosen the tension on the belt in a 1995 Chevy Caprice so I can replace the alternator?

Click on the following direct Link. It has several Serpentine Diagrams; one of which matches your specific engine and options (ex: AC/No AC etc).
Regarding HOW:
Standard Rule to Removal the Serpentine Belt:
1. Find the Tensioner(s). (See Diagrams on Link)
2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT OR OPENING (3/8ths or 1/2 inch square opening) 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
Standard Rules for Installing the Serpentine Belt:
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.
Let me know if this helped...

How do you get the alternator back on 2003 2500

The belt tension is automatically adjusted with the tennsioner pulley. As far as putting it back on, I am not sure what you mean, you just need to bolt it back up and pull the belt over the pulley.
