Remove Battery
- Disconnect the negative terminal first, then the positive terminal.
- Remove any brackets holding the battery in place and lift the battery out carefully.
Install New Battery
- Place the new battery in the tray.
- Connect the positive terminal first, followed by the negative terminal.
- Tighten connections securely to avoid future issues.

3. Starter Motor Inspection and Replacement

Access Starter Motor
- Depending on the engine configuration, you may need to lift the vehicle and remove the undercarriage shield to access the starter.
Remove Starter Motor
- Disconnect the wiring harness from the starter.
- Remove the bolts securing the starter motor to the engine block using a socket set.
