A water pump circulates coolant between the engine and the radiator. Signs this engine water pump may need replacing include coolant seeping from the pump, a noisy or wobbling pulley, or a rising temperature gauge. If a failed pump is the cause, this mechanical unit replaces it. It is a street/high-performance part and is not for competition use. The listed applications use one pump. Country of origin: China.
