This multi-ribbed belt transmits power from the engine crankshaft to the accessory drive components, including the alternator, water pump, and fan. It operates within the front engine accessory drive system, routing around multiple pulleys to maintain tension and grip. A worn or glazed belt slips under load, causing undercharging, overheating, or reduced hydraulic pump output. The eight-rib profile matches the original pulley grooves to maintain proper contact area and tension retention. When replacing, inspect all pulleys for wear and ensure the belt tensioner is within its operating range.
