[DML] Re: Alternator Belt

["Harold McElraft" <hmcelraft@xxxxxxx>]

If the belt has been tightened correctly it should be quiet. If the 
belt is making noise then you need a new belt. That soap and 
dressing is for used car guys to help in a fast sale. It is unlikely 
you will get the correct tension doing it with the screwdriver as 
tight as you can method.
