Disconnect the battery. This will help to prevent any accidental electrical shocks while you are working.
Remove the serpentine belt. This is the belt that drives the alternator, among other accessories. To remove it, you will need a serpentine belt tool. Start by inserting the tool into the slot next to the alternator, and then turn the tool clockwise. This will loosen the belt and make it possible to remove it.
Remove the alternator electrical connections. There are two electrical connections that need to be removed. One is the positive battery terminal connection, and the other is the ground terminal connection. To remove the positive battery terminal connection, use a wrench to loosen the nut that holds the cable in place. Then, pull the cable off the terminal. To remove the ground terminal connection, use a wrench to loosen the bolt that holds the cable in place. Then, pull the cable off the terminal.
Remove the alternator mounting bolts. There are two mounting bolts that hold the alternator in place. To remove them, you will need a wrench. Once you have removed the bolts, you can lift the alternator out of the car.
Install the new alternator. To install the new alternator, reverse the steps that you took to remove the old alternator. Be sure to torque the mounting bolts to the specified torque.
Reconnect the battery. Reconnect the battery cables in the reverse order that you disconnected them. Tighten the nuts and bolts until they are snug.
Check the alternator. Start the car and let it run for a few minutes. Then, use a voltmeter to check the voltage at the battery. The voltage should be between 13.5 and 14.5 volts. If the voltage is not within this range, there may be a problem with the alternator.
