What part is that?

To the detectives here in the forum: I am at the end with my Latin. Mercedes also did not manage to identify the part for today’s visit. I myself have Webparts access and have already searched for the soul out of my body. Without success. On the picture is a 2005 G500 which is being worked up. The oil cooler at the lower screen edge is only temporary attached. Furthermore, the hood lock from above hangs in front of the affected part into the picture. So do not let it irritate. It is about the fat, screwed-on cross beam with the five horizontal holes. The most similar thing EPC spits out for the VIN is A4636200130, but the part looks completely different. Since the cross beam has set rust, I wanted to renew it in the course of the general reprocessing. But for this I would have to know what it is. Heeelp!!
