yeah i just changed my belts this weekend. There is an alternator mounting bolt right below the alt. Loosen that some so that you can move the alternator down some to slacken the belt. Also loosen the tensioner bolt for the alt belt that is to the left of the alternator. Go to
this site to get an idea on how to change the belts. Its for a pulley install, but it shows the steps for taking off the belts. Make sure to loosen the tensioner lock bolt before loosening the tensioner bolt.
