I am wondering what this line/hose is for. It is close to my mr d/v and it started to rub against it. Not sure if it is vacuum, oil, or coolant? Thanks

Thats a water feed pipe for the turbo!

Great question, and great answer. I had no idea, but that is good to know!!

Damn good thing I didn't wait any longer to ask. So I will definitely lose some coolant replacing the rubber hose piece in the middle?

I hope you are not putting "dress-up" lines in place of an OEM piece, that is asking for trouble!

Hell no man... you see any dress up in that engine bay?? I can see some wear on the hose from where the d/v was rubbing but no gouges, scrapes, etc. I still would like to replace it before it does go spurting coolant and what not.

You know hes going to dress it up lol
