I would be grateful for a little help. What is the P/N of the hose in Dwg 472 that goes from 17 to the firewall? I can't seem to find it in any of the diagrams on Real OEM... I am assuming it has a plastic connector (female) that mates to the male end on 17? Is there some sort of an O-ring in there? Replacing this hose looks like it would be a real pain since it runs through the whole engine bay...
My '06 325i is leaking from the connection between 17 and this long hose. It's also leaking from a small crack on top of the radiator outlet that connects to 17. That part is plastic and has cracked along the mold seam. So, <sigh....> need to replace the radiator, 17, and, potentially, the long hose to the firewall. Probably should do the water pump while I am at it. The current one went in at 88K back in 2012...
Thank you!
