How do you change a serpentine belt on a 2000

Depending on the size of the motor the belt tesioner turns clockwise. find a wrench to put on the bolt of the pulley itself and turn it clockwise this will release the tension on the belt allowing you to pull it off the first available pulley. Just take it off that one pulley "Alternator, Power steering pump, Idler pulley whichever is closest and easiest to remove the belt off of go with that one. Unfortunately i was unable to find a belt diagram for you. There should be a diagram for you on under the hood this will tell you where to put the belt around each pulley. You do not have to hold the tensioner as you take the belt off each pulley after the first release it slowly. as you put the belt back on around each pulley leave the belt off that one pulley that u started with. Grab the tensioner again turn it clockwise as done before and put the belt on that one pulley release it and your done. Check each pulley to make sure the belt is on right if it is off by one groove it can and will throw the belt the first time you start the vehicle. then you would have to start the process all over again. If there are anymore questions feel free to reply and i will get back to you.
