Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Battery and Connections

Check the battery terminals for corrosion. Clean if necessary using a wire brush.
Tighten any loose connections to the battery and ground points.

3. Check Starter Motor

Remove the starter motor from its mounting (typically requires a socket set).
Inspect the starter gear and internal components for damage or wear.
If faulty, replace the starter motor with a new unit according to manufacturer specifications.

4. Serpentine Belt Inspection

Check the serpentine belt for signs of wear, fraying, or damage.
If the belt is worn, replace it following these sub-steps:
- Release tension on the belt using a belt tensioner tool.
- Remove the old belt and route the new belt according to the routing diagram.
- Ensure proper tension is applied to the new belt.

5. Reassemble and Reconnect

Reinstall any components removed during inspection.
Reconnect the negative battery terminal.
