Product Details

Gates Molded Coolant Hose products are built for specific vehicle applications and mirror the essential OE-style features needed for proper fitment. This hose includes molded routing and modular components rather than a universal straight-hose layout, which helps maintain the original cooling-system configuration on BMW 528i, 525i, and 530i models listed for the auxiliary water pump outlet. If you are sourcing a BMW 528i coolant hose or a BMW 530i radiator coolant hose, Gates 24128 is the catalog reference to verify.

This part cross-references Bosch 16792 and Dayco 88506 for the same application.

What This Hose Helps Address

• Coolant leaks at a cracked or aged hose body
• Loose or worn quick-connect hose connections
• Improper hose routing after cooling-system service
• Heat-related deterioration in the auxiliary water pump outlet line
• Cooling-system flow issues caused by a damaged molded hose

Installation Notes and Tips

Verify the vehicle year, model, and auxiliary water pump outlet location before ordering. Compare the original hose routing, connector style, and end diameters to the Gates 24128 before installation. Inspect mating connectors and surrounding cooling-system components for wear, contamination, or damage so the new hose seats correctly.

Quality Assurance

Gates is a recognized aftermarket supplier of modular coolant hose assemblies, and this hose is manufactured to application-specific OE-style requirements for the listed BMW fitments. Part number 24128 is intended for accurate replacement selection on the confirmed applications.
