I decided to tackle this job early, everything is fine but now that I have removed the old radiator and go to but in my new Behr radiator, which I thought was OEM, there are two additional holes. One hole has a block off screw (shown) but one does not. Does anyone know where I can get another? worst case I will call the place I ordered from Monday, but was hoping to wrap this up tomorrow! I did check local auto stores but they dont have this. Maybe Mercedes does?

Thanks! I went there and asked the guy if they had something and his said no. I will go back tomorrow and look myself!

mickey13

Couldnt seem to find what I needed, guess I will be calling the supplier on Monday!! Stuck with no car right now

i think you could have installed it without plugging the hole.

yes, you can leave those holes unplugged. They're for the classic setup with auto trans cooling within the same radiator as for the engine coolant. You won't use those hole since the C43 trans cooling is setup differently.

Really? it seems to me like theyre open? I guess I will test it out.

Poured water in those holes, they are not connected to the rest of the unit! I feel like a dummy
Spent all weekend with no car!
