This multi-ribbed belt drives the cooling fan, transferring power from the engine crankshaft to the fan hub. It is an original AGCO component, meaning its rib profile and pitch match the pulley grooves of the assembly for which it was designed. A worn or slipping belt reduces airflow across the radiator and charge-air cooler, leading to elevated coolant and intake-air temperatures. On installation, ensure the belt is routed correctly over all idler and tensioner pulleys and that the tensioner is set to the manufacturer’s specification.
