Restore proper coolant circulation and cooling system reliability with this OEM replacement Radiator Coolant Hose Water Pipe for select BMW F-Chassis models equipped with B38, B48, and N20 engines. Designed to replace OE part number 17128602027, this coolant hose assembly plays an important role in maintaining proper coolant flow between key cooling system components, helping your BMW maintain stable operating temperatures during daily driving, performance driving, and varying weather conditions.

Over time, factory coolant hoses are exposed to constant heat cycles, coolant pressure, and engine bay temperatures.

Replacing aging coolant hoses is an important preventative maintenance step that helps protect your BMW’s cooling system and overall engine reliability.

This replacement cylinder head coolant hose is engineered to match the factory routing, connections, and installation design of the original cooling system component. Whether you are repairing a coolant leak, refreshing your cooling system, replacing worn factory components, or performing preventative maintenance, this hose provides a dependable solution designed to restore confidence in your BMW’s cooling performance.
