Which belt is which cls 55 omg




As for routing the belt, the serpentine is about 7 miles long and turns about 23 pulleys. It seems like that when you're installing it, anyway.

The supercharger belt has to come off to replace it. Both belts have spring tensioners that you turn with a socket wrench to remove and install, there's none of the old-fashioned pry the alternator out to tighten the belt.
(The picture is from my S55 docs, but it's the same engine.)
The supercharger belt only goes over three pulleys: the crank, the supercharger, and its tensioner pulley.
