Solution

1. Preparation

Gather tools including a multimeter, socket set, and wrench set.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Inspection

Clean battery terminals with a wire brush to remove corrosion.
Tighten the battery connections securely.
If the battery voltage is below 12.4 volts, consider replacing the battery.

3. Starter Motor Replacement (if necessary)

Remove any components obstructing access to the starter motor (e.g., air intake duct).
Disconnect the electrical connections from the starter motor (note their positions).
Unscrew the starter mounting bolts using a socket set.
Carefully remove the starter motor from its housing.

4. Install the New Starter Motor

Position the new starter motor in place and align it with the mounting holes.
Securely fasten the mounting bolts to the manufacturer’s specified torque (typically around 15-20 ft-lbs).
Reconnect the electrical connectors to the starter motor.
Replace any components removed for access.

5. Final Steps

Reconnect the negative terminal of the battery.
Start the vehicle to verify that the clicking noise is resolved.
