[Product Features] The electric water pump precisely controls coolant flow, allowing for more efficient engine and inverter temperature management. It operates even when the engine is off, continuously cooling the electric motor and inverter. This ensures that the cooling system is always operating at its optimum. By providing highly efficient cooling and protecting against overheating, it optimizes engine and electric system performance. The electric water pump is also designed to minimize noise during operation. [Compatible Vehicles] Compatible with Toyota Prius 20 Series NHW20. For details, please see the product details page. [Genuine Part Number] Compatible only with vehicles equipped with G9020-47030, G9020-47031, or 04000-32528. [Product Description] The electric water pump is used to cool the electric motor and inverter in hybrid vehicles. By circulating coolant even when the engine is off, it prevents overheating and maintains component performance and reliability. Unlike traditional mechanical water pumps, electric water pumps can more precisely control the coolant flow rate.

[Deterioration Phenomena] We recommend replacing your water pump as soon as possible if you experience any of the following symptoms: 1. Decreased cooling performance: If the electric water pump is unable to circulate coolant properly, causing the electric motor or inverter to overheat, replacement is required. 2. Leaks: If the water pump is leaking coolant, especially from the pump body or connections, this may be due to a broken sealing ring or a crack in the pump body. 3. Abnormal noises: If the pump makes unusual noises (such as squealing or clicking) while operating, this may be due to wear or damage to internal components. 4. Malfunctions: If the electric water pump does not operate properly or will not start, this may be due to a faulty electric motor or an electrical connection problem.
