Mounting the New Starter

4. Position the starter: Align it with the mounting holes on the engine block. Verify that the rotation direction (clockwise) matches the vehicle’s specifications.
5. Tighten bolts: Secure the starter using a torque wrench set to the manufacturer’s recommended value (typically 15–20 Nm).
6. Reconnect wiring: Attach the high‑current harness and any auxiliary connectors. Ensure all connections are tight and free of corrosion.

Final Checks

• Verify that the starter’s housing is flush with the engine block to avoid interference during cranking.
• Reconnect the battery and perform a test start, listening for smooth operation without excessive noise or vibration.
• Check for any warning lights on the dashboard; if none appear, installation is successful.
