Name or Part Number?




If I had to guess I think it's: https://classicparts.mbusa.com/oem-p...ine-2782000900
I recommend you do all the turbo coolant lines at the same time. My independent repair shop did 2 lines in 2021, and the 3rd one burst open on the drive home, thankfully he did the last one for free since he felt bad that literally I drove off and all the coolant leaked again. Thats because it was brittle and no longer had the strength. So do all 3 turbo coolant lines at the same time is my recommendation. It's 14, 16, and 17 in the diagram. Whichever ones are the plastic ones, those are the ones to redo.

Very easy swap out, very easy. What is common is for the 90 that goes into the engine will also be brittle and break. If that happens just take a soldering iron - melt out the old one and replace that as well. This is a sign that all of the smaller coolant hoses would like to be changed.
