Here are the items you'll need for this repair: new belt from, 3/8 ratchet

Before removing your serpentine belt, be sure that the path is indicated somewhere in the engine bay, either on the original sticker like ours has here, or if yours is missing, simply take a marker or paint pen and draw one somewhere under the hood. Using the open end drive of a 3/8 ratchet, place it into the square inlet on the serpentine belt tensioner and rotate clockwise. Remove the belt from the pulley. Carefully release the tension. Remove your ratchet, and take your belt off the rest of the way. It's a little tricky to get it off this idler pulley here, so be careful not to cut it on this piece of steel. The rest should come off pretty easily.

Install the serpentine belt first around the harmonic balancer, or the crank pulley. Be sure that it's seated on there fully. I'll now take the passenger side of the belt and route it under my water pump, back up over the top of the water pump. From here, it'll go over the top of my tensioner pulley, under my A/C compressor on the bottom passenger side, through this tight little gap here, and over the idler pulley. I'll then go to the bottom driver's side and ride the belt around my power steering pump. I'll put some tension on it by hand, make sure that everything is seated properly on its pulleys, and then use the drive of a 3/8 ratchet in the square opening of the tensioner, and turn that clockwise to relieve the pressure, and install my serp belt over the top of my alternator before releasing the pressure and removing my ratchet. Double check that your routing is correct, and that the belt is fully seated on all pulleys before starting the vehicle.
