Answer 2

A serpentine belt on an engine is held in place by a pulley that maintains the proper tension on the belt. This pulley can be pulled up to release the tension on the belt. Do not pull the pulley out, but gently up or you'll risk damaging it.

Answer 3

The serpentine belt on a 1997 Mercedes C280 is replaced by loosening the belt tensioner and sliding the belt off. It can then be pulled from the remaining engine accessories and a new belt installed.

Answer 4

Pay attention to where the serpentine belt runs and what pulleys it goes over or under. Draw a diagram if you need to. Use a wrench or socket to release tension on the belt tensioner and pull off the old belt. Put the new belt around all the pulleys except for the belt tensioner and then when its on all the pulleys except for that one, release tension on it again and put the belt on that pulley, then let the pulley go and it will put tension on the new belt.
