This water pump circulates coolant through the engine block and radiator to maintain operating temperature. It is driven by the engine’s belt system and mounts directly to the front of the engine housing. The pump includes the necessary gaskets for installation. A failing pump typically produces coolant leakage from the weep hole or bearing noise, followed by overheating. The original-manufacturer casting matches the housing bore and impeller clearance of the assembly it replaces, so no shimming or adapter plates are required. On reinstall, clean the mating surfaces and torque the mounting bolts to specification.
