- Reconnect terminals securely, starting with the positive terminal.

3. Starter Motor Replacement

Sub-steps:
- Locate the starter motor (usually near the transmission).
- Remove any components obstructing access to the starter (e.g., air intake duct).
- Disconnect the electrical connectors from the starter motor.
- Remove mounting bolts using a socket set.
- Carefully remove the starter motor from its housing.
- Install the new starter motor by reversing the removal steps.
