【Product Features】The electric water pump precisely controls the flow rate of the coolant, resulting in more efficient temperature management of the engine and inverter. It operates even when the engine is stopped, continuing to cool the electric motor and inverter. This ensures the cooling system remains in optimal condition at all times. It provides highly efficient cooling and protects against overheating, optimizing the performance of the engine and electric systems. Furthermore, the electric water pump is designed for quiet operation, minimizing noise during use.
【Main Compatible Vehicles】Fits Toyota Prius 20 series NHW20. Please refer to the product details page for more information.
【Genuine Part Number】Limited to vehicles with one of the following part numbers: G9020-47030, G9020-47031, 04000-32528.
【Product Description】The electric water pump is used to cool the electric motor and inverter of mixed-power vehicles. By circulating coolant even when the engine is stopped, it prevents overheating and maintains the performance and reliability of the components. Unlike conventional mechanical water pumps, electric water pumps can control the coolant flow rate with greater precision.
[Deterioration Symptoms] If any of the following symptoms occur, we recommend replacing the water pump as soon as possible. ① Reduced cooling performance: If the electric water pump is unable to circulate the coolant properly and the electric motor or inverter overheats, replacement is necessary. ② Leakage: If coolant is leaking from the water pump, especially from the pump body or connection points, it may be due to a damaged seal ring or a crack in the pump body. ③ Abnormal noise: If the pump makes unusual noises (e.g., squeaking or clicking) while operating, it may indicate wear or damage to internal components. ④ Malfunction: If the electric water pump does not operate normally or does not start, it may be due to a malfunction of the electric motor or a problem with the electrical connection.
