BMW N55 Coolant Return Hose – OEM Cooling System Replacement, Replaces 17128570061 - Fits F22 F23 F30 F31 F32 F33 F34 F36 & F87 Models

Restore proper coolant flow and long-term cooling system reliability with this OEM-style Coolant Return Hose replacement for BMW N55-powered F-Series vehicles. Designed as a direct replacement for the factory return line, this hose helps maintain stable coolant circulation while supporting proper engine operating temperatures under daily driving and more demanding conditions.

Over time, original coolant hoses can become brittle from repeated heat cycles, pressure changes, and general aging. As the material weakens, cracks, seepage, and full hose failure become much more likely, which can lead to coolant loss, reduced cooling efficiency, overheating concerns, and costly engine damage. Replacing worn cooling system hoses before they fail is one of the smartest preventative maintenance steps you can take on an N55-powered BMW.

Manufactured from high-quality automotive-grade materials, this coolant return hose is built to withstand the heat and pressure demands of BMW’s turbocharged N55 platform. The precision-molded design helps ensure factory-style fitment and proper routing within the original cooling system, making installation clean and straightforward.

Whether you are fixing an active coolant leak, refreshing an aging cooling system, or replacing old factory hoses as preventative maintenance, this replacement hose helps restore cooling system integrity while maintaining the reliability and performance your BMW was designed to deliver.
