BMW F01/F02/F03/F04 7 Series Radiator Hose – OEM Replacement Cooling System Hose, Replaces OE 7578398 - Fits 2009–2015 7 Series Models

Restore proper coolant flow and cooling system reliability with this OEM replacement radiator hose for the BMW F01, F02, F03, and F04 7 Series. Designed to replace OE reference 7578398, this hose plays an important role in maintaining stable coolant circulation throughout the engine’s cooling system so your 7 Series can continue operating at the proper temperature under daily driving and higher-load conditions.

As these vehicles age, factory coolant hoses can begin to harden, weaken, swell, or crack from years of heat cycles and constant coolant exposure. Once that happens, even a small weak point can quickly turn into a coolant leak, pressure loss, or overheating issue. Replacing aging hoses before they fail is one of the smartest preventative maintenance steps you can take to protect the engine and cooling system on a modern BMW.

This replacement radiator hose is designed to match the original routing and fitment of the factory hose, making it a dependable solution whether you are addressing a coolant leak, refreshing the cooling system, or replacing worn original components during preventative maintenance. It helps restore confidence in the cooling system while keeping the engine bay functioning the way it should.
