4. Install the new battery by placing it in the tray.
5. Connect the positive terminal first, followed by the negative terminal.
6. Tighten the terminals securely and ensure they are corrosion-free.

3. Starter Motor Replacement (if necessary)

Tools Required: Socket set, torque wrench, screwdriver, multimeter
Sub-steps:
1. Disconnect the negative battery terminal again for safety.
2. Locate the starter motor, usually situated near the transmission.
3. Remove any components obstructing access to the starter (e.g., air intake hoses).
4. Disconnect the electrical connectors from the starter motor.
5. Remove the mounting bolts securing the starter motor using a socket wrench.
6. Carefully extract the starter motor and replace it with a new one.
7. Reconnect the electrical connectors and secure the starter motor with mounting bolts (torque to manufacturer specifications, typically around 10-15 ft-lbs).

4. Final Checks
