Original BMW S38 Radiator Hose for BMW E24 M6 and E28 M5 (1987–1988)

Made for the S38 engine, Original BMW radiator hose 11-53-1-310-625 carries coolant between the engine and its cooling system components on the 1988 BMW M5 (E28) and the 1987–1988 BMW M6 (E24). BMW's own name for the part is simply Hose, and it comes as a single piece weighing 228 g (0.5 lb). BMW's parts data shows production of this number beginning in December 1986. A radiator hose moves coolant to and from the radiator and the rest of the cooling system, so a leaking hose lets coolant escape and puts the engine at risk of overheating.

This Original BMW hose carries a 24-month parts warranty.

BMW names the part only as Hose, so the part name gives no upper or lower position and no indication of where each end connects. The part number is therefore the dependable way to match it. The E28 M5 and E24 M6 share this one hose, and both carry the S38 engine, so a single part serves either car.

Common Questions

What signs show it is time to replace this hose?
Cracking, leaking, swelling, and general deterioration are the common failure signs. With age the rubber can also dry out and turn hard or brittle.

Does it fit a standard E28 535i or E24 635CSi?
BMW's application data for this number covers only the S38-powered M cars, and it is not shown for other E28 or E24 models.

Factory hoses keep an E28 M5 or E24 M6 cooling system the way BMW specified it.
