This multi-ribbed belt transmits power from the engine crankshaft to the cooling fan and water pump. It is a 4PK profile belt, meaning it has four longitudinal ribs that engage with matching pulleys on the drive system. The belt sits in the front engine accessory drive, where it maintains tension to prevent slip under varying load conditions. A worn or glazed belt produces a squealing noise at start-up and reduces coolant flow, leading to elevated engine temperatures. As an original AGCO component, the belt is molded to the same rib profile and pitch length as the original assembly, ensuring proper seating in the pulley grooves without requiring tensioner adjustment beyond the standard range.
