Serpentine Belt Replacement 2012 ML350 Blutec

I just had my serpentine belt start to come apart, the pieces also cut the AC Discharge hose while it was at it and all the freon(?) hissed out.... fun times. However I was looking online for instructions on the serpentine belt replacement but to no avail - I'd realy like to do it right - (plus tackle an oil leak in there if I can) - anyone have any links on a how to? search on here didn't turn up anything. Much thanks!!!

Replacing idler pulleys

I need to replace the idler pulleys on my 2013 MB ML350 Bluetec Diesel engine, but they have covers on them and I have no idea how to remove the cover to get to the bolt head.
Any assistance would be greatly appreciated.

What do you mean by covers? Does it look like the photo in the earlier post?
