The Bosch 0 392 023 457 is an electric auxiliary water pump engineered to provide supplemental coolant circulation in modern vehicle cooling systems. This OEM-quality pump is designed to operate independently of engine speed, ensuring consistent coolant flow for optimal thermal management.

Key Features:

• 12-volt electric operation for reliable performance
• 0.1 bar operating pressure for efficient coolant circulation
• Brushless motor design for extended service life and reduced maintenance
• Sealed pump chamber protects electronic components from coolant exposure
• Factory function and leak tested for quality assurance
• Direct OEM replacement ensuring exact fit and proper function

Bosch auxiliary water pumps feature advanced electronics with integrated diagnostics and are built to withstand high temperatures up to 130°C. The electric design eliminates parasitic engine drag, allowing the cooling system to operate as needed rather than being driven mechanically by the engine. This pump is commonly used in heating systems, turbocharger cooling circuits, and supplemental cooling applications where continuous coolant flow is required even when the engine is off.
