This is the most important step, as it will help prevent any electrical shock while working on the alternator. To disconnect the battery, simply loosen the negative battery terminal bolt and remove the cable from the battery.
Step 2: Remove the serpentine belt.
The serpentine belt is the belt that drives the alternator, so it will need to be removed before you can remove the alternator. To remove the serpentine belt, you will need to use a wrench to loosen the tensioner pulley. Once the tensioner pulley is loose, you can easily slip the belt off of the pulleys.
Step 3: Remove the alternator bolts.
There are four bolts that hold the alternator in place. To remove these bolts, you will need to use a wrench. Once the bolts are removed, you can carefully lift the alternator out of the car.
Step 4: Disconnect the electrical connections.
There are two electrical connections that need to be disconnected before you can remove the alternator. The first is the positive battery cable, which is connected to the alternator with a nut. The second is the field wire, which is connected to the alternator with a small screw. To disconnect these connections, simply use a wrench to loosen the nut or screw.
Step 5: Remove the old alternator.
Once you have disconnected the electrical connections, you can remove the old alternator from the car. Be careful not to drop the alternator, as it is a heavy piece of equipment.
Step 6: Install the new alternator.
To install the new alternator, simply reverse the steps that you took to remove the old alternator. Be sure to tighten all of the bolts and screws securely.
Step 7: Connect the electrical connections.
Connect the positive battery cable and the field wire to the new alternator. Be sure to tighten the nut and screw securely.
Step 8: Install the serpentine belt.
Slip the serpentine belt back onto the pulleys and then tighten the tensioner pulley.
Step 9: Reconnect the battery.
Reconnect the negative battery terminal cable to the battery. Be sure to tighten the bolt securely.
Step 10: Test the alternator.
Start the car and let it run for a few minutes. Check the voltage at the battery to make sure that the alternator is charging properly. The voltage should be between 13.5 and 14.5 volts.
If the voltage is not correct, you may need to have the alternator tested or replaced.
