Install New Battery
- Place the new battery in the tray, ensuring correct orientation (positive and negative sides).
- Secure with hold-down bolts.
Reconnect Battery
- Connect the positive terminal first, then the negative terminal.
- Ensure terminals are tight and free of corrosion.

3. Starter Motor Inspection

Access Starter Motor
- Raise the vehicle and secure it with jack stands.
- Locate the starter motor (typically found near the transmission).
Remove Starter
- Disconnect the electrical connections (ensure the battery is disconnected).
- Remove the mounting bolts and carefully take out the starter motor.
