Serpentine Belt replacement.
 

Hi everybody,
I'm new to the forum and owner of a MCS 06 R53.
The belt tensioner broke a couple weeks ago and I'm replacing it myself. I would like to have information about the type of bolts holding the belt tensioner since I lost mine on the freeway and I can't find any informations about that anywhere and WMW takes time to answer me about a potential bolts set for the belt tensioner.
Also I changed the Crankshaft puller since the belt tensioner destroy it for a M7 +4%.
So now I have a +15% Alta pulley on the supercharger and a +4% M7 crank pulley, if someone got that setup, which belt do you got for that because I wonder if you need a special size for it !?
Thanks for your answers.
