Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection

Inspect the battery for corrosion on terminals.
Clean terminals using a wire brush if corrosion is present.
Test battery voltage with a multimeter; it should read 12.6V or higher.

3. Starter Motor Removal

Locate the starter motor; it is typically found near the transmission.
Remove any wiring harnesses connected to the starter motor.
Unscrew the mounting bolts using a socket set (typically 10mm or 13mm).
Carefully remove the starter motor from its mounting position.

4. Flywheel Inspection

Inspect the flywheel for missing teeth or damage.
If teeth are missing, the flywheel may need to be replaced.

5. Install New Starter Motor
