- Unhook the battery. - Remove the drivebelt from the alternator and other accesories. There will be a belt tensioner pulley that you can use a socket on to lossen up the tension so the belt drops. The belt tensioner pulley is on a spring and automatically tightens. - Take off the electrical connections from the alterntor on the back. - Unbolt the mounting bolts on the alternator. - Install new alternator bolt it up, put the wires back on, put the belt back on and your set. Its very easy on this car compared to the smaller more modern cars. It should only take you about and hour or two if you have the V8. I strongly recommend that you pick up a repair manual for your car.
