Hi Mike here from Florida. A friend gave me two new cooling hoses for his E39 that he has since parted with. I have the part numbers still on the hoses but don't know what cooling hoses are for. Does anyone know of a way that I can cross reference the hose numbers back to the year vehicle the hoses will fit and if there is a way to determine what the hoses are or where under the hood they fit? Let me know when you can at mjbergin50@gmail.com Thanks, ---Mike Bergin, 124628
