Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection and Replacement

Inspect the battery:
- Check voltage using a multimeter; it should read around 12.6 volts or higher.
- Clean battery terminals with a wire brush if corrosion is present.
Replace battery if it is unable to hold a charge or is significantly degraded.
- Remove the positive terminal first, followed by the negative terminal.
- Install the new battery by connecting the positive terminal first, then the negative.

3. Starter Motor Inspection and Replacement

Remove the starter motor:
- Locate the starter motor, usually found near the engine block.
- Disconnect electrical connectors from the starter.
- Unbolt the starter from its mounting position (usually requires a socket set).
Test the starter motor:
- Use a multimeter to check for continuity and proper function.
Replace starter motor if it is faulty.
- Install the new starter motor by reversing the removal process.
- Ensure all connections are secure and tightened to the manufacturer's torque specifications.

4. Drive Belt Inspection and Replacement

Inspect the drive belt:
- Look for signs of wear, cracks, or fraying.
Replace the drive belt if damaged.
- Loosen the tensioner pulley using a socket set to relieve tension.
- Remove the old belt and install the new belt, ensuring it is routed correctly.
- Reapply tension to the belt by tightening the tensioner pulley.
