how do i change the serpentine belt

here is link to the repair info for your Pontiac http://bit.ly/mitchell_repair_manuals_online

Place a jack underneath the motor an the side of the car the belt is on. After the motor is supported loosen the two motor mount bolts then jack up the engine just a little. place a 3/8 ratchet in the belt tinsoiner and push the handle away from you this will take tension off the belt. Remove the belt pull it up between the motor mount and the mount bracket. There should be a belt diagram to reinstall the new belt somewhere underneath the hood. Cdhaze@msn.com
