Solution

1. Preparation

Gather necessary tools and parts for the repair.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion with a wire brush.
- Tighten any loose connections.
Test Battery:
- If the battery voltage is below 12.6 volts, proceed to battery replacement.
- Remove the battery by disconnecting the negative terminal first, followed by the positive terminal.
- Use a socket set to remove the battery hold-down bracket.
- Replace with a new battery, ensuring proper terminal connections (positive first, then negative).

3. Starter Replacement

Remove Starter:
- Locate the starter motor (typically near the transmission).
- Disconnect electrical connectors from the starter.
- Remove the mounting bolts using a socket set.
- Carefully extract the starter from the engine compartment.
Install New Starter:
- Position the new starter in place and secure it with mounting bolts (tighten to manufacturer's specified torque).
- Reconnect the electrical connections to the starter.

4. Reconnect Battery

Reconnect the negative terminal of the battery.
Ensure all connections are tight and secure.
