Original BMW Cylinder Head to Radiator Coolant Hose for BMW X5 xDrive35d F15 (2014–2018)

This Original BMW coolant hose carries coolant from the cylinder head to the radiator on the 2014–2018 BMW X5 xDrive35d, where the N57N diesel sends hot coolant out to be cooled before it returns to the engine. BMW names the part the line from cylinder head to radiator and assigns it part number 17-12-8-514-218 within the F15 X5's engine cooling system. Any radiator hose has to stay flexible so the engine can move on its mounts while coolant keeps flowing between it and the radiator. Coolant leaving the cylinder head is at the hottest point in the loop, which puts this line on the hot side of the system. This hose is made in the United States and weighs 369 g (0.8 lb).

Original BMW Parts carry a 24-month parts warranty.

BMW's production data starts this hose in August 2013, and no supersession appears against the number, so every X5 xDrive35d in the fitment range takes the same part. BMW identifies it by its route from the cylinder head to the radiator. It is sold as a single hose.

Common Questions

What are the signs this hose is due for replacement?
Cracking, leaking, swelling, and general deterioration are the failure signs to look for. With age, these hoses dry out and turn hard and brittle.

Will this hose fit a gasoline X5 from the same years?
No. This hose is for the diesel X5 xDrive35d, so confirm your X5 is the diesel model before ordering.
