There are tons of alternator change out on youtube. Most cars are about the same. 1) disconnect negative battery (if not you're going to fry yourself when disconnecting power to alternator. 2) diconnect power to alternator 3) unbolt main housing to alternator (2 or 3 bolts) 4) install new alternator 5) make sure the belt lines up with new alternator 6) tighten belt by adding leverage to your new alternator (crow bar or long steel tube) 7) tighten bolts, tighten power line, make sure belt is tight, hook up battery, and crank it up. Tools needed, adjustable wrench, socket set, screw driver, crow bar or steel tube. Good luck.
