    Hose Identification Help

    Any help identifying these two hoses? I have searched RealOEM and did extensive Googling and came up empty.



    Thanks!

    Did you look at the heater diagrams?

      Yep. Those are the hoses kind of underneath the hoses I am asking about.

        #9 and #11 in the diagram in the link is the two hoses you have circled in red.

          ForcedFireBird, I think that's almost right. The small hose coming off the T (#12 in your link) is #11 . It runs from that tee down to the bypass valve, #8 in the diagram. However, the larger hose is actually #13 from this diagram:

          http://www.realoem.com/bmw/enUS/show...diagId=11_1167

          When that heater bypass system was added, they cut #13 to insert the T.

          So venerated, to replace that hose, you'll need #13 in the link. You can either cut it and reinsert the T, or else delete the heater bypass. The heater bypass came as a result of a lawsuit when a heater core failed and dumped hot coolant on a passenger. In my mind, it's just another set of hoses and valves to fail. If you replace #12 and #13 in the link, you can just leave out the bypass valve, the T, and the small hose that runs between them.
