The number stamped on the part is 64128379872; BMW's catalog files it under the short number 8379872. You will find it on our AC & Climate Control shelf, under Other Heater and Air Conditioning parts. It supersedes the older number 8371888, so a part carrying that number is the same part.
BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.
BMW draws it on 9 diagrams, among them Independent heating water valves (64_0627) and Independent heating water valves (64_0697). It weighs about 96 g (0.2 lb). It also comes in BMW kits Upgrade kit, bypass water circuit (2147028) and Install.kit, independent heater (2165613) and 11 more.
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
