why does my Honda Accord make a loud grinding noise when starting?

Solution

1. Preparation

• Gather tools and parts required.
• Disconnect the negative battery terminal to prevent electrical shock.
• Ensure the vehicle is in park or neutral with the parking brake engaged.

2. Remove the Starter Motor

• Locate the starter motor, typically mounted on the engine block.
• Remove any covers or shields obstructing access to the starter.
• Disconnect the electrical connections to the starter (battery and solenoid).
• Unbolt the starter motor using the appropriate socket size and remove it from the engine.

3. Inspect the Flywheel

• Visually inspect the flywheel for any signs of wear, cracks, or missing teeth.
• Rotate the flywheel manually (if accessible) to check for smooth operation.
• Replace the flywheel if damage is found.

4. Test and Replace Starter Motor

• Use a multimeter to test the starter motor's continuity and resistance.
• If the starter is faulty, replace it with a new or refurbished unit.
• Reinstall the starter motor, ensuring it is securely bolted and connections are tight.

5. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the engine to verify that the grinding noise is resolved.
