How do you put the alternator belt back on a 97 maxima after replacing alternator?

Once the alternator is bolted in and hanging on its curved barcket, you slip the belt over the pulleys and pull back on the alternator until it's just snug. Then you find the tensioner bolt/screw for the idler pulley at the end of the bracket. Tighten this bolt until the belt has about 1/8" give at the midway point between pulleys. I think all you need is a 14mm and a 12mm socket with a short extension to do all of it.
