Hello fest, I have a coolant leak from here. I took a quick picture of the leak and wanted to see if I could replace this part or of it is part of the upper radiation hose as one part. It's not the rubber house that leaking and it's still hot so I can't tell if it's plastic or metal or what. ImageUploadedByBimmerApp1476908378.407174.jpg

Thanks all. Don't really want to keep driving it with it leaking so hopefully can get it resolved today. Thanks

I can't tell what it's connected to. Here's a list of radiator hoses from real OEM. It appears they come with the connectors already attached. I put in a May 2007 production date. You may want to change that. But I don't think the hoses changed much over the years.

Generally most of the radiator crap is plastic on the BMWs. Unfortunately!
