Product Overview
Coolant seepage, a soft or swollen hose, cracking near the fittings or white residue around the expansion tank can indicate a hose that is no longer sealing correctly. A small leak can gradually lower coolant level and create overheating risk.
This replacement hose restores the coolant connection between the engine cooling circuit and expansion tank on compatible BMW applications. Match the hose routing, quick-connect ends and vehicle configuration before installation.
