Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Allow the engine to cool before starting work to prevent burns.

2. Inspect and Replace Belts

Tools Required: Socket set, belt tensioner tool
Check the serpentine belt for cracks, frays, or glazing.
If damaged, loosen the belt tension using the tensioner tool.
Remove the old belt and install a new one, ensuring proper routing.
Tighten to manufacturer's specifications.

3. Check and Replace Tires

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench
Inspect each tire for signs of uneven wear or damage.
Inflate tires to the recommended pressure as indicated on the driver’s door jamb.
Replace any tires that are excessively worn or damaged.
Reinstall tires and torque lug nuts to manufacturer's specifications.

4. Brake System Inspection

Tools Required: Jack, jack stands, brake caliper tool
Remove the wheel to access the brake system.
Inspect brake pads for wear; if less than 3mm thick, replace them.
Check calipers for proper operation and replace if they are sticking.
Reassemble the wheel and lower the vehicle.

5. Electrical System Check

Tools Required: Multimeter
Inspect wiring around the engine bay for any signs of melting or damage.
Use a multimeter to check for proper voltage and continuity in critical circuits.
Replace any damaged wiring or connectors.
