1. Gather Tools and Materials:
- Replacement alternator
- 10mm socket wrench
- 13mm socket wrench
- 15mm socket wrench
- Pry bar
- Flat head screwdriver
- Wrench
- Safety goggles and gloves
2. Disconnect the Battery:
- Open the hood and locate the negative battery terminal.
- Loosen the nut holding the negative terminal using a 10mm socket wrench.
- Lift off the terminal and set it aside, ensuring it doesn't touch any metal surfaces.
3. Remove the Serpentine Belt:
- Locate the serpentine belt tensioner near the alternator.
- Insert a pry bar or long screwdriver into the tensioner and push down on the lever to relieve the tension.
- Remove the belt from the alternator pulley.
4. Disconnect Electrical Connectors:
- Follow the electrical connectors running from the alternator to the vehicle's harness.
- Use a flathead screwdriver to release the tabs securing the connectors.
- Disconnect all the electrical connectors from the alternator.
5. Remove the Alternator Bolts:
- Locate the bolts holding the alternator in place using the 13mm and 15mm socket wrenches.
- Remove the bolts securing the alternator to the mounting brackets.
6. Remove the Alternator:
- Once the bolts are removed, slightly wiggle the alternator to break free any corrosion or sealant.
- Gently lift the alternator out of the engine bay.
7. Install the New Alternator:
- Position the new alternator into place, aligning it with the mounting brackets.
- Insert the bolts into the mounting brackets and tighten them using the 13mm and 15mm socket wrenches.
- Ensure the alternator is securely mounted.
8. Reconnect Electrical Connectors:
- Reconnect the electrical connectors you disconnected earlier, ensuring they snap into place securely.
9. Install the Serpentine Belt:
- Place the serpentine belt around the alternator pulley and the other pulleys on the engine.
- Use the pry bar or screwdriver to tension the belt by pushing down on the tensioner lever.
- Ensure the belt is aligned properly and has the correct amount of tension.
10. Reconnect the Battery:
- Return to the battery and place the negative terminal back onto the battery post.
- Tighten the nut using a 10mm socket wrench.
11. Test the Alternator:
- Start the engine and let it run for a few minutes.
- Turn on the headlights and other electrical components to put a load on the alternator.
- Check the battery voltage using a voltmeter. It should read between 13.5 and 14.5 volts with the engine running.
If the battery voltage is within the specified range, then the alternator has been successfully replaced. Be sure to dispose of the old alternator properly.
