Well I was doing my timing belt kit and was removing a hose that connected to this black pipe. There was a hose connecting to it, and while trying to remove the seized hose, it snapped off. I was wondering if anyone could identify this part, how much it would cost.

 

Looks like the turbo coolant return line nipple. It broke off from under that large metal pipe right?

You can see it in this photo on the left:



That pipe that it broke off is the upper coolant pipe. A brand new pipe will cost you over $100. You're better off pulling one from a junkyard or finding someone parting out their car.

I could also look for one for you when I go to the pick n pull soon.
