Remove the wires going to the alternator. Mark them with a piece of tape so you can put them back to the same terminal.
there are probably two bolts that need to be removed. One will be fastened to a slotted strap. Removing this one will allow the alternator to pivot on the remaining bolt. This will be the one that allows the fan belt to be removed from the pulley on the alternator. Removing the 2nd will allow the alternator to be removed from the engine.
Installation of the replacement is the reverse procedure. Aftere you install the 2nd bolt, put the fan belt back in the slot and pull the alternator so the slack is taken up in the belt, then tighten the bolt
