Greetings,


We are trying to figure out what goes in the Tranmission oil cooler's top part, where currently the cork is. (I've marked it on the pictures with red)
Car: 2.0L 2014 CLA45 AMG, Which we are restoring after a crash


i'm not an expert in engines or anything, however, my mechanic can't figure out what to put in here (He didn't assemble the car, he just took over the project, so therefor he dont know what was in there in the first place).
Do we just plug it in with a plastic thing? (like this image )

I'

What goes there instead of the cork plug???


It's in the transmission oil cooler.


ALl the help is greatly appreciated, regards Daniel.
