I have huge white smoke coming from the engine bay and found out that the belt was melted. So I need to replace the serpentine belt. WHile searching for the belt's routing photographs, I found 2 that are different. One of them has an additional pulley, in red circle; the otther doesn't. It is also in the parts diagrams, #35. Is this a late/early difference for f430s? Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
Applicable to engine number 117479 and onwards "Belt tightening pulley" https://www.eurospares.co.uk/Parts/226205/Maserati/New/13611
Drive belts don't just "melt" on their own. Something seized and caused the belt to self destruct. I suggest further investigation to determine the cause of the belt failure.
