SOURCE: serpentine belt
the belt is being pulled by a spring loaded pulley. this pulley could be lift by using an exact box wrench that would fit at the front nut and turn the wrench to the left. the pulley would then raise and you can slide the belt off the pulley. be careful when releasing the pulley because the tension is really big.
another precaution also is to remember where the belt loops on the pulleys. it is very hard if you don't take a note on that. there are a lot of combination but only one will work.
tnx 4 using fixya.

If you will look under the hood around the radiator or on the underside of the hood it should be on a sticker there for you to look at.

Ok, Alternators are a breeze on these things. There are two bolts that hold it on, and 2 sets of wires. If you haven't taken anything apart yet, and the belt is still on it, here's what to do. You will want one of those rubber or elastic bungee cords, about 2 and a half feet long(this makes it easy). Hook that bungee cord to your hood somewhere, so that it hangs down. Hook the other end on the serpentine belt right next to the alternator pulley. If you need to prop the hood up with a stick or something to keep it up, do so. Pull up on the belt, and watch the pulleys. The one that probably has a plastic pulley on it that moves up and down(this is the tensioner) is the one that you'll put a deep well socket in the middle of with a ratchet, and turn counterclockwise. This will make the belt go loose. Now you can work the belt off the alternator pulley, and once you get it off, the bungee cord will keep it in place, so you don't have to look at the diagram. Otherwise, if it comes off, there is a sticker just under the hood either on the fan shroud or the radiator support that has the belt diagram. Now, you can disconnect the battery, pull the rubber boot down off the nut and post on the back of the alternator, remove the nut and wire, and then unhook the wire from the side of the alternator. Now, you can remove the two bolts that hold the alternator on. You Will need to pry the alternator off at this point, as it fits really tightly in place. A socket extension or a large flat screwdriver works really well for this. Once you get it off, put the new one on exactly as you took the old one off. Note, you will have to release your tension on the tensioner at some point; i just ease it down, or if I can pull it off, wedge it somewhere where it won't loosen very far. Remember, on the tensioner, you're not trying to take the nut off. All you're doing is using it to move the tensioner arm. That's all there is to this job. Sometimes it can be stubborn with the prying part, especially getting it into place. Hope this is what you're after, and if you need more info, leave a comment for me.

The routing diagram should be at the front of the hood.Use a rached with short extention to move the tensioner on the belt for removal and replace..Hope this helps.
SOURCE: how to move the serpentine
You don`t have to remove the pulley itself.Use a light and look at the tensioner.You will see a square hole on the front of the tensioner.All you need to do is put your 3/8 ratchet in this hole and relieve the tension.Then just remove the belt off the alternator and leave it lay on the other pulleys.You don`t need to remove it completely.This will make it easier when installing it.Hope this helps.Good luck.
