Drive Belt: Description and Operation

The L36 employs a single serpentine belt which drives each of the engine mounted accessories. The belt is wider than conventional belts due to its "Poly-V" design, similar to six narrow V-belts joined at their sides. Encircling each accessory pulley are six grooves which mate with the contours of the belt face. The exception to this is the water pump pulley which is driven by the back side of the serpentine belt and, consequently, does not require grooves.
