Ok to remove the serpentine belt, you will need to release the tension by turning the belt tensioner clockwise, This is done by using a 3/8" drive ratchet in the back side of the tensioner. You will see a small hex to put the ratchet in. Note #8 in the illustration. There is actually a belt tensioner tool that you can rent from most auto part stores. Here is the illustration. Just keep inmind that the tensioner is spring loaded and will require you to keep it in the unloaded position until you get the belt off, and then until you get the belt back on. Feel free to contact me with any questions! Good luck!
