The belt tensioner is the same on all models according to the parts lists, #05096525AA. Mercedes part number A112 200 09 70.

The SRT6 tensioner is different though, part number A112 200 07 70

The 17mm hexagonal boss and the locking pin hole are not seen from the top.

The hexagonal boss can be seen in a mirror.

The SRT6 uses the Torx head for tension relief. Use the correct size to prevent stripping it.

Pin ( 3/16") is shown in the hole used to lock the tensioner in position to keep the belt tension free for service.


Another photo by James 1549. Do NOT use this Torx screw to relieve the belt tension.
