When I went to replace the top radiator hose, about 3/8 inch of the plastic end of the expansion tank broke off and was attacted to the end of the radiator hose. The part that broke off is clearly part of the expansion tank; are those 2 separate parts or are they one part? On my radiator, the expansion tank appears to be attached to the radiator, on the driver's side.Need to order some parts
Learn to use realoem.com, it will become your best friend: http://www.realoem.com/bmw/showparts.do?model=HD53&mospid=47404&btnr=17_0099&hg=17&fg=05 It is a separate part, but I suggest you think really hard about the other plastic bits in your cooling system.
Paul, I decided to replace all the parts on the diagram you sent. Where would you suggest going for these parts? I usually use oembimmerparts.com but have not been able to contact them. Thanks
