This engine water pump circulates coolant through the block and radiator to maintain the operating temperature of the host tractor. It is driven by the engine’s accessory belt and mounts directly to the front cover of the engine block. The impeller inside the pump housing moves coolant from the lower radiator hose into the engine jacket; a failed pump reduces flow, causing the engine to overheat under load. This component is manufactured by AGCO and is built to the same casting and seal geometry as the original assembly, so it seats against the block without additional gaskets or shims. On installation, clean the mating surface and torque the mounting bolts to specification.
