How do you you tighten the alternator belt on a 1991 Plymouth Acclaim?

Answer 1

The adjuster is located underneath the alternator. Three bolts are involved, the first to loosen is the main bolt that hangs the alternator to its bracket, the second is underneath the unit on the left hand side - this would be the actual locking nut. The third is down underneath yet towards the front of the alternator; it actually moves the entire alternator forward or backward thus tightening or loosening the belt. Once the belt is tight, tighten the lock nut and then the main attaching bolt. About the lock nut, it is part of the adjuster mechanism underneath the alternator; both the lock nut and adjuster bolt are difficult to see especially if you have air conditioning like I use to.
