why is my Ford Explorer making a clicking noise when I start it

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, battery terminal cleaner, and a load tester.
• Ensure the vehicle is in park (or neutral) and the parking brake is engaged.

2. Battery Maintenance

1. Disconnect the negative battery terminal using a socket set.
2. Clean the battery terminals with a battery terminal cleaner to remove any corrosion.
3. Reconnect the negative terminal securely.

3. Battery Replacement (if needed)

1. If the battery voltage is low or the load test fails, remove the old battery by unbolting it from the battery tray.
2. Install the new battery by placing it in the tray and securing it with bolts.
3. Connect the positive terminal first, followed by the negative terminal.

4. Starter Testing/Replacement

1. If the issue persists, locate the starter motor (typically found near the transmission).
2. Disconnect the wiring harness and the mounting bolts using a socket set.
3. Remove the starter motor from the vehicle.
4. Install a new or tested starter motor in reverse order of removal, ensuring all connections are secure.

5. Final Checks

1. Reconnect the negative battery terminal.
2. Attempt to start the vehicle to check for proper operation.
