99 Mazda Miata Alternator Belt Replacement

If the alternator is on the top in the open, just loosen the alternator bolts a little bit. Then push the alternator to loosen the belt to remove it. Do the opposite to put the new belt on.

If the alternator is buried under a lot of other things, it's a lot tougher job.
Hope this helps.
