You have an x253 (2016-2022) and there’s a forum for that, that’s my point. This is the x254 forum for the next gen 2023 GLC.
@moderators, move this thread to appropriate forum, along with the other threads wrongly posted in this forum. Clearly there's some confusion happening. Thanks!
Happy New Year!

In many MB models the hose connections to the circulation pump behind the left headlamp show crusty dried coolant residue and are one source of “sweating” and coolant odor.
Sweating = leak, but MB service boys don’t like the word “leak”.
