08 View BMW DiagramSee this part on the official exploded view→Genuine BMW part 17 21 7 638 579: Heat exchanger. The number stamped on the part is 17217638579; BMW's catalog files it under the short number 7638579. You will find it on our Cooling System shelf, under Oil cooler. It supersedes the older number 7597891, 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 the Heat exch./transmission oil cooler line (17_0501) diagram. It weighs about 1.1 kg (2.5 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
