using a long 14mm wrench or socket, pull counterclockwise on the tensioner pulley, it's spring loaded so if the pulley you're on doesn't move, that's not the right one. as you're looking down, it's just to the left of the crack pulley.
remove the belt, slipping it around the fan, and then put the new belt in position. there's a diagram on a sticker on the hood. make sure the belt is in all the grooves or it'll shred it as soon as you start the car.
