The engine usually has an idler and/or tensioning pulley as well as a few pulleys that use the power of a traveling serpentine belt to drive components such as the alternator, a/c pump, etc. Any of the pulleys that have one or more grooves that assist to guide the belt(s) are, technically, sheaves.

Disengage the idler arm lever ( it is a spring loaded arm located on your deck on left side). There is a bracket that holds it in place. Push arm forward over bracket then carefully allow arm to release all the way back. This will remove tension from belt. Then simply slide belt over pulleys keeping track of how they are aligned on pulleys. When installing new belt be sure belt is aligned in both front pulleys and be sure all belts are set in pulleys before reengaging idler arm lever.
