CLK 320CDI idler pulley

[ellmo]

Hi all,

have noticed that I have a rattle coming from the highest pulley on the serpentine belt, I presume this is the idler pully.

Can anyone confirm the part number please?

If one pulley is rattling I would think the others are probably shot. When you have the serpentine belt off check all of them for noise in the bearings.
