Ensure the vehicle is parked on a level surface with the engine turned off and the keys removed.
Wear safety glasses and gloves when handling the battery.

2. Battery Replacement (if necessary)

Disconnect Old Battery:
- Use a socket set to loosen the negative terminal first, then the positive terminal.
- Remove the battery hold-down bracket if applicable.
Remove Old Battery:
- Carefully lift the battery out of the tray.
Clean Battery Tray and Terminals:
- Use a wire brush and corrosion cleaner to clean the battery terminals and the battery tray.
Install New Battery:
- Place the new battery in the tray, ensuring it is secure.
- Connect the positive terminal first, followed by the negative terminal.
Test New Battery:
- Start the engine and ensure that the battery voltage is within the correct range.

3. Alternator Repair/Replacement (if necessary)

Remove the Alternator:
- Disconnect the negative battery terminal.
- Remove the serpentine belt by releasing tension on the tensioner and sliding the belt off.
- Disconnect the electrical connectors and remove bolts securing the alternator.
Install New Alternator:
- Position the new alternator in place and secure it with bolts.
- Reconnect the electrical connectors and reinstall the serpentine belt.
Test the Charging System:
- Start the vehicle and measure the voltage at the battery again to confirm proper alternator function.
