- Disconnect the negative battery terminal (_located on the battery post_) using a wrench.
- This will prevent any electrical accidents while working on the alternator.
Step 2: Remove the serpentine belt.
- Find the tensioner pulley (usually located on the upper portion of the engine).
- Use a breaker bar or ratchet and socket to release the tension on the belt by rotating the tensioner pulley.
- Once the tension is released, remove the serpentine belt from its routing.
Step 3: Remove the alternator bracket.
- Locate the alternator bracket attached to the engine block.
- There may be multiple bolts or nuts that need to be loosened to remove the bracket.
- Remove the bracket and be sure to set aside any attaching hardware.
Step 4: Disconnect the alternator wiring.
- Locate the electrical connections on the alternator.
- Disconnect these connections by either removing the nuts/ bolts that secure the wires or by pressing on the release tab or squeezing the wire connector to unlock it.
Step 5: Remove the alternator.
- Locate the mounting bolts that attach the alternator to the engine block.
- Use a wrench or socket to loosen and remove these bolts.
- Once the bolts are removed, carefully maneuver the alternator out of the vehicle taking care not to drop it.
Step 6: Install the new alternator.
- Position the new alternator in place, aligning the mounting holes.
- Thread in the mounting bolts and tighten them securely using a wrench or socket.
Step 7: Reconnect the alternator wiring.
- Reconnect the electrical connections to the alternator.
- Push the connectors until they click into place or reattach the nuts and bolts that secured the wires.
Step 8: Reinstall the alternator bracket.
- Reinstall the alternator bracket by aligning the mounting holes.
-Secure it with the bolts or nuts that were removed in Step 3.
Step 9: Reinstall the serpentine belt.
- Route the serpentine belt around the alternator and other pulleys according to the belt routing diagram.
- Adjust the tensioner pulley to properly tension the belt.
Step 10: Reconnect the battery.
- Reconnect the negative battery terminal back onto the battery post.
Step 11: Start the vehicle and check for proper charging.
- Start the vehicle and use a multimeter to check the voltage output at the battery terminals.
- The voltage should be around 14-14.5 volts when the engine is running at idle if a standard 12 volt battery is installed.
