ANSWER:
Most late model cars use serpentine belts to drive all or most accessories. Serpentine belts are long and follow a complex path that weaves around the various pulleys. Serpentine belts are flat on the outside and have a series of continuous ribs on the inside. These ribs fit into matching grooves on the pulleys. Both the ribbed side and the flat side can be used to transfer power. Most serpentine belts use an automatic tensioner to maintain ideal belt tension throughout the life of the belt.
