Solution

1. Preparation

Tools Required: Socket set, flashlight, multimeter, tire pressure gauge
Ensure the vehicle is parked on a flat surface and the engine is cool before starting work.

2. Inspect and Replace Worn Belts

Sub-steps:
1. Open the hood and visually inspect all drive belts for fraying, cracking, or excessive wear.
2. If a belt is damaged, use a socket set to loosen the tensioner pulley and remove the old belt.
3. Install a new belt by routing it according to the belt diagram typically found on a sticker in the engine bay.
4. Adjust the tension using the tensioner pulley and ensure it is secured.

3. Check and Maintain Tires

Sub-steps:
1. Inspect tires for uneven wear or damage. Look for cracks, bulges, or foreign objects.
2. Measure tire pressure with a tire pressure gauge; inflate to the manufacturer's recommended PSI if low.
3. If tires are worn, replace them with new tires of the correct size and rating for the vehicle.

4. Inspect Electrical Components

Sub-steps:
1. Check all wiring and connectors for signs of melting or burning; replace any damaged components.
2. Use a multimeter to test the alternator’s output; it should read between 13.8 to 14.4 volts.
3. If the alternator is faulty, disconnect the battery, remove the alternator, and install a new one.
