Very simple belt to change, you will have no trouble. Remove the top bolt on the alternator adjustment bracket, loosen the lower alternator mounting bolt so it can tip forward. Put the new belt over the fan and lay it in the fan pulley, go under the crankshaft pulley. now start it over the top of the alternator pulley, you may have to pull the on a fan blade to roll it into the pulley groove. Now snug up the lower bolt leaving it just loose enough to pivot the alternator. Start the top bolt back into the alternator, pull it toward you till belt is snug, tighten top bolt, then lower bolt.
The reason for tipping the alternator forward will become apparent when you try to put the belt on the last pulley as the belt will be a hair too short. By tilting the alternator forward, it lowers the pulley enough to install the belt.
