Original BMW Engine Coolant Hose for BMW X1, X3, X4, X5, and Z4 with N20 Engine (2012–2018)

Genuine BMW coolant hose 11-53-8-645-479 moves engine coolant between cooling system components on the N20 engine in the BMW X1, X3, X4, X5, and Z4. BMW names it the water hose. It weighs 252 g, is made in Poland, and has been in production since November 2014. Coolant hoses carry hot coolant under pressure between the engine, radiator, and other cooling parts, and over time they dry out, harden, and turn brittle. Swelling, cracking, leaking, and general deterioration are the usual signs that this hose is due.

Original BMW Parts carry a 24-month parts warranty.

This number superseded hose 11-53-4-614-609. BMW rates the change as exchangeable retrospectively, so it is the correct part for cars built with the earlier hose. Number 11-53-7-615-608 also cross-references to this hose. Because it is an N20-specific part, it is shared across five chassis: the E84 X1, F25 X3, F26 X4, F15 X5, and E89 Z4. That shared use is why one hose covers such a wide spread of models and years.
