On a 2001 300M you use and 18" ratchet extension, or combination of extensions, to loosen the tensioner. You can loosen it by loosening the center pulley bolt from the top. Then from under the car, use your ratchet and extension and turn counterclockwise in the tensioner bolt. This will allow you to remove the old belt. Do the reverse to replace the belt. I also remove the bolts from the crossmember body piece, like you do to replace your headlights.
The ac belt will need to have the tensioner to take the belt off. The serpentine belt is in front of the compressor belt and will have to be removed first.

The alternator on a Chrysler 300m can be replaced by disconnecting the battery, removing the wiring harness from the alternator, and then unbolting it from the mounts. The drive belt can then be slipped off and a new alternator put into place.

There is not a diagram under the hood showing how to replace the serpentine belt. Can you show me a diagram?
Either have him replace it or get a second opinion.
Yes
