This is a genuine BMW water hose, part number 64 21 8 363 863. The number stamped on the part is 64218363863; BMW's catalog files it under the short number 8363863. You will find it on our AC & Climate Control shelf, under Other Heater and Air Conditioning parts.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on 2 diagrams, among them Independent heating water valves (64_0697) and Independent heating water valves (64_0699). It weighs about 48 g (0.1 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
