Hello! First post here. I see a lot of good info on here. I blew a fitting on the coolant system right at the firewall immediately after the heater core (aka heat exchanger) just past the firewall poking into the engine compartment.

I'm looking through my software but having difficulty determining if I can remove the windshield wiper assembly or if this is a "remove the dash" project.

The picture I found that seems relevant:


Picture from my software

Picture Mercedes sent me


If anyone has had any experience with this: I'd appreciate knowing:
• What the name of the part is (and/or a part number)
• Whats involved in accessing to replace it

I will get a picture of the actual car soon and upload.

I plan on making a youtube video of my repair as it seems good Mercedes Repair videos are hard to come by.
