Step-by-Step Process
Step 1:
Pop your hood by pulling out on the lever that is to the left of the emergency brake pedal.
Once the lever is pulled, go to the front of the vehicle and lift up on the lever that is under the center of your hood.
Use caution when working on your vehicle.
Step 2:
The alternator is placed on the right center side of the engine bay.
If your car has been running recently, make sure that the engine has cooled off before trying to work.
Step 3:
Remove the negative terminal from the battery.
'''Warning:''' Always make sure that the negative terminal of the battery is disconnected when working inside the engine bay.
Step 4:
Use a 15 mm socket on the tensioner to remove the belt.
Step 5:
Remove the connector on the back of the alternator by pinching and pulling back.
Step 6:
Remove the rubber covering on the nut and bolt assembly on the back of the alternator.
Remove the nut with a 10 mm socket.
Step 7:
Remove the two bolts on the front of the alternator with a 15 mm socket.
Step 8:
Once the two bolts in the front are removed, the alternator is ready to come out.
The alternator might need a little persuasion to come off the bracket, so use a hammer or a pry bar to aid you in this step.
When using a hammer, make sure that you are not coming into contact with anything on the backswing. The last thing you want to do is damage an entirely different part under your hood.
Step 9:
Now you are ready to install your new alternator.
To accomplish this you will need a hammer to tap your alternator into place.
The objective here is to line up the bolt holes on the bracket with those on your new alternator.
Step 10:
Once your new alternator is in place, feed the two bolts back through their corresponding holes on the front of the bracket.
Tighten the bolts down with a 15 mm socket.
Step 11:
Once the front two bolts are tightened down, put the connector back into the top slot.
Step 12:
Place the wiring connector back onto the bolt on the backside of the alternator.
Put the nut on and tighten it down using a 10 mm socket.
Step 13:
Place the rubber cover back over the nut.
Step 14:
Realign the belt into its proper position.
Place the belt in between your 15 mm socket and the tensioner.
Turn the tensioner to the right to relieve the tension and place the belt back on.
Once you have done this, release the pressure you are applying to the tensioner and make sure that the belt is properly aligned.
Use caution when placing the belt back on. Do not release the tensioner until you have aligned the belt or you could pinch your finger.
Step 15:
Reconnect your negative terminal back to the battery.
After this you should be good to go!
