Look for the idler pully,it will be the one that runs against the back of your surpentine belt,It is spring loaded,it is smooth,use a breaker bar or 1/2 drive ratchet,there is a bolt head that sticks out of the front of the pulley find a socket that fits this bolt head it should be metric,make sure that you take note on how it is already installed so you can reinstall it the same way,using your tool put the correct socket on the bolt and pull in the direction that the pulley moves freely,then you can remove the old belt,there should be a schemetic on your radiator support that shows the routing of your belts.
You must loosen the nut on the tensioner pully the from under the car there is a tensioning bolt 12mm you will tighten it and it will pull the pully down then take the belt off, new one on, then loosen the tensioner bolt til the belts tight and tighten the bolt in the middle of the pully then your all done
you loosen the bolts on the opposite sides of it. then, you change the alternater, and tighten the bolts.
Well if its set up like most other engines it will have a tension pully that keeps the pully tight. they arent hooked up to power anything. theyre just bolted on so take it off and the pully will go slack. if the engine has a serpentine belt you may need to remove two. just remember to put them back on.
Typically, there is one pulley that is mounted on a spring arm to maintain proper belt tension. Just turn the bolt on the idler pulley and the tensioner will release.

What I did was loosen off the motor mount on the left side, take a 2x4 wooden b lock place it on a floor jack and put under the oil pan and rase the engin enough so you can get you wrench on to the tention pully and change your belt.
