Original BMW Radiator Coolant Hose for BMW 535d, 535d xDrive, and 740Ld xDrive (2014–2016)

Original BMW coolant hose 17-12-8-513-603 carries engine coolant to and from the radiator on the BMW 535d, 535d xDrive, and 740Ld xDrive with the N57 diesel engine. BMW gives it the plain name coolant hose, and on the 535d and 535d xDrive it is item 1 in the radiator diagram. The hose is made in Germany and has been in BMW production since July 2011. Radiator hoses move coolant between the engine, the radiator, and the rest of the cooling circuit, and they do that work under heat and pressure every time the engine runs. With age the rubber can dry out, harden, and turn brittle, and at that point replacement is due.

Original BMW Parts carry a 24-month parts warranty.

This number replaced the earlier hose 17-12-7-811-982, and BMW marks the change as retrospectively interchangeable, so the current part also fits cars that were built with the older number. If the hose on your car carries that earlier number, this is the correct replacement for it. BMW applies the same hose to both the earlier and facelift versions of these models, so this one number covers both versions..

Common Questions

What signs mean this hose needs replacing?
Cracking, leaking, swelling, and general deterioration of the rubber are the signs to look for. A hose showing any deformity should be replaced right away.

Is this the same hose a BMW dealer supplies?
Yes. It is a new, unused Original BMW part, the same one sold through BMW dealer parts departments.
