CUMMINS-4BT-6BT-WATER-PUMP

3802358 is the water pump for Cummins 4BT and 6BT engines, driving coolant flow through the block and radiator via a belt-driven impeller. As with most water pumps, the shaft seal is the component that fails first — a weep of coolant from the pump's weep hole is the manufacturer-designed early warning sign, and it's worth checking for on any routine inspection rather than waiting for a puddle under the engine.
