Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Inspect and Replace Worn Belts

Sub-steps:
- Remove the engine cover if applicable.
- Visually inspect the serpentine belt and timing belt for cracks or fraying.
- If damaged, use a wrench to loosen the tensioner and remove the old belt.
- Install the new belt, ensuring it follows the correct routing.
- Re-tighten the tensioner to the manufacturer's specifications.
Tools Required: Socket set, wrench set, belt tensioner tool (if necessary).

3. Examine and Replace Tires

Sub-steps:
- Check tire pressure with a tire gauge; inflate to recommended PSI if low.
- Inspect tire tread for uneven wear; replace tires if necessary.
- Ensure proper wheel alignment using an alignment tool; adjust as needed.
Tools Required: Tire pressure gauge, alignment tools.

4. Inspect and Service Brake Components

Sub-steps:
- Remove the wheel to gain access to the brake assembly.
- Inspect brake pads for wear and calipers for sticking.
- If calipers are stuck, consider cleaning or replacing them.
- Reinstall the wheel and torque the lug nuts to the manufacturer’s specification.
Tools Required: Jack and jack stands, lug wrench, brake cleaner.

5. Check for Fluid Leaks

Sub-steps:
- Clean the area around potential leak sources (engine, transmission, etc.).
- Start the vehicle and observe for any new leaks.
- If leaks are found, identify the source and replace gaskets or seals as needed.
Tools Required: Cleaning rags, fluid catch pan.
