Compatible With BMW M240i, BMW M240i xDrive, BMW 440i, BMW 440i Gran Coupe, BMW 440i xDrive, BMW 440i xDrive Gran Coupe, BMW i8, BMW M4, BMW 340i GT xDrive, BMW 340i, BMW 340i xDrive, and BMW M3 applications listed below.

Key Features

• 100% new construction for direct replacement use.
• Clockwise rotation for the specified BMW auxiliary cooling applications.
• Vacuum leak tested to verify sealing integrity.
• Torque tested to confirm impeller-to-shaft mating.
• OE mating parts and accessories used for fitment verification.
• Mixed-material construction with one inlet and one outlet port.

Detailed Description

This Bosch auxiliary water pump is designed around exact OE specifications and validated through functional testing before release. Bosch checks torque at the impeller-shaft interface and performs vacuum leak testing to identify sealing issues in the housing, seals, tube binding, and plug areas. Fitment verification also uses OE mating components such as the pulley, brake plate, housing, and tensioners. Bosch 039202411C is a practical replacement for BMW cooling-system service where the auxiliary pump must match the original design and rotation.

This part cross-references BMW 11518600442 for the same application.

What It Helps Address

• Auxiliary coolant circulation problems caused by a worn or failed pump.
• Leak-related cooling system loss from compromised seals or housing sealing surfaces.
• Impeller or shaft connection issues that affect pump operation.
• Incorrect pump rotation concerns during BMW cooling system repair.
• Fitment issues when replacing the original BMW auxiliary water pump.

Installation Notes

Confirm the vehicle uses the auxiliary water pump application listed in the fitment table before installation. This pump does not include mounting hardware, a gasket or seal, or a mounting bracket. Verify clockwise rotation and port orientation against the original unit, and inspect mating components during replacement.
