Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shorts.
Gather necessary tools and parts.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion from the battery terminals using a wire brush.
- Tighten the terminal connections securely.
Replace Battery if Needed:
- If the battery voltage is below 12.4 volts or fails the load test, replace it.
- Remove the old battery by loosening the terminal clamps, then unscrewing the battery hold-down clamp.
- Install the new battery by placing it in the tray, securing it with the hold-down clamp, and reconnecting the positive (+) terminal first, followed by the negative (-) terminal.

3. Starter Motor Inspection and Replacement

Inspect Starter Motor:
- Locate the starter motor, typically found on the lower part of the engine near the transmission.
- Check all electrical connections to the starter for corrosion and tightness.
Replace Starter Motor if Needed:
- Disconnect the electrical connections from the starter.
- Remove the starter mounting bolts using a socket set.
- Install the new starter by reversing the removal process and ensuring all connections are secure.

4. Final Checks

Reconnect the negative battery terminal.
Test the vehicle by attempting to start the engine.
