Solution

1. Preparation

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

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion from battery terminals and cable connections using a wire brush.
- Tighten loose connections securely.
Battery Replacement (if necessary)
- Remove the battery hold-down bracket using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery from the tray.
- Place the new battery in the tray and connect the positive terminal first, followed by the negative terminal.
- Secure the battery with the hold-down bracket.

3. Starter Inspection and Replacement

Remove Starter
- Locate the starter motor (typically near the bottom of the engine).
- Disconnect the electrical connectors from the starter solenoid.
- Remove the mounting bolts securing the starter to the engine using a socket set.
- Carefully remove the starter from its housing.
Install New Starter
- Position the new starter in place and secure it with mounting bolts; torque to manufacturer specifications (usually around 30-40 ft-lbs).
- Reconnect the electrical connectors to the starter solenoid.

4. Finalization

Reconnect the negative battery terminal.
Start the vehicle to ensure proper operation.
