Best Answer

First, you need to take off the belt. next you need to disconnect the battery. then take a 13mm wrench and remove 3-4 bolts. two on the back, 1 on the bottom by the tension pulley then one long one in front. remove wires, then insert new alternator, bolt back on. connect wires. be sure to insert bottom bolt first (its the hardest) then the others. fit belt back on, then connect battery and start it up!
