Genuine Nissan Water Pump

The water pump is the heart of a car's cooling system as it transports water cooled by the radiator to the engine block. After the cooled water goes through the engine block, it is sent back through the pump to the radiator, creating a constant, ever-flowing supply of needed cool water. If the Nissan water pump stops functioning, the coolant temperature remains stagnant and the engine will over-heat, majorly damaging its components.
