Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion from the terminals using a wire brush.
- Tighten any loose connections securely.
Test and Replace Battery
- If the battery voltage is below 12.6 volts, replace the battery.
- Remove the old battery by unbolting the hold-down bracket and disconnecting the positive cable first, followed by the negative cable.
- Install the new battery by connecting the negative terminal first, followed by the positive terminal, and secure the hold-down bracket.

3. Starter Motor Inspection and Replacement

Remove Starter Motor
- Locate the starter motor; it is typically mounted on the transmission bell housing.
- Disconnect the electrical connectors from the starter motor.
- Unbolt the starter motor using the appropriate socket size and remove it from the vehicle.
Inspect and Replace Starter
- Visually inspect the starter for any signs of wear, damage, or debris.
- If faulty, replace with a new or remanufactured starter motor.
- Install the new starter by reversing the removal steps and torque the mounting bolts to the manufacturer's specifications.

4. Final Assembly

Reconnect the battery terminals, ensuring they are tight.
Start the engine to confirm that the clicking noise is resolved.
