This water pump circulates coolant through the engine block and radiator to maintain operating temperature. It is driven by the engine's accessory belt and uses an impeller to move fluid at a consistent flow rate. A failed pump typically causes coolant leakage from the weep hole, overheating, or bearing noise. The set includes four gaskets for the housing and pump interfaces; replace all gaskets on reinstall and torque the mounting bolts to specification. As an original AGCO-manufactured component, the impeller clearance and seal face geometry match the housing casting, so no shimming or adapter modifications are needed.
