Question How do I figure out this M104 belt tensioner???!!!

I was going to post pics of my alternator and serpentine belt replacement, but my de-install is not going very smoothly.

Got the fan shroud and fan off okay, but I am either short on tools (MB seems to like those allen bolts) or I am looking at the wrong places.

I gave up last night and just pulled the old belt off of one of the pulleys by hand and then slid the rest off. So now the alternator swap will be a cinch, but I am fearful of how to get the new (tighter) belt back on.

The Haynes manual was of no help, as the idler pulley bolt it specifies didn't exist, etc. etc.
