Best Answer

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.
