Engine Auxiliary Water Pump Overview

Bosch Engine Auxiliary Water Pump 0392024117 is a new replacement pump built to original equipment specifications. It is engineered for BMW applications that require a clockwise-rotation auxiliary cooling pump, with fitment verified against OE mating components.

Key Features

• 100% new construction for direct replacement use.
• Clockwise rotation for the specified cooling system application.
• Single inlet and single outlet port layout.
• Mixed-material construction for the pump assembly.
• Torque-tested and vacuum leak-tested for function and sealing.

Detailed Description

This Bosch auxiliary water pump is designed to meet exact original equipment specifications and is tested for proper operation before release. Torque testing checks impeller-to-shaft mating, while vacuum leak testing checks sealing integrity across the housing, seals, tube binding, and plug areas. The Bosch 0392024117 is a practical replacement for BMW cooling system service where the auxiliary pump must match OE fit and rotation requirements. It cross-references BMW 11518637953 for the same application.

Common Issues It May Solve

• Auxiliary coolant circulation loss.
• Cooling system leaks at the pump housing or seals.
• Improper pump rotation for the application.
• Fitment problems caused by non-OE-style replacement parts.
• Reduced cooling performance from a worn auxiliary pump.

Installation Notes and Tips

Confirm the part number 0392024117, rotation direction, and OE-style connector and port layout before installation. This pump does not include mounting hardware or a gasket or seal. Verify the BMW application and cooling system configuration against the vehicle’s original pump before replacement.

Quality Assurance

Bosch tests each water pump for proper functionality, including torque testing and vacuum leak testing, to help confirm sealing and impeller-shaft integrity. The 0392024117 is built to original equipment specifications and verified with OE mating parts and accessories.
