Solution

1. Preparation

Gather tools and ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal to ensure safety during inspection and repair.

2. Battery Inspection

Inspect the battery terminals:
- Remove any corrosion using a mixture of baking soda and water.
- Tighten any loose connections.
If battery voltage is low (below 12.4 volts):
- Jump-start the vehicle or replace the battery if it fails to hold a charge.

3. Starter Motor and Solenoid Replacement

If the starter motor is determined to be faulty:
- Disconnect the battery (negative terminal first).
- Remove the starter motor:
  1. Disconnect the wiring harness and positive cable from the starter.
  2. Remove the mounting bolts (typically 2-3 bolts, torque specifications may vary; consult the service manual).
  3. Carefully pull the starter out of its housing.
- Install the new starter:
  1. Position the new starter in place and secure it with the mounting bolts.
  2. Reconnect the positive cable and wiring harness.

4. Final Assembly

Reconnect the negative battery terminal securely.
Ensure all tools and debris are cleared from the engine bay.
