Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before beginning work.

2. Inspect and Replace Worn Belts

Sub-steps:
1. Open the hood and locate the serpentine belt and accessory belts.
2. Visually inspect the belts for cracks, fraying, or signs of wear.
3. If any belts are worn, use a socket set to loosen the tensioner and remove the old belts.
4. Install new belts by routing them according to the belt routing diagram found in the engine bay.
5. Tighten the tensioner to the manufacturer's specifications (typically around 15-30 ft-lbs).

3. Check Tire Condition

Sub-steps:
1. Inspect all four tires for signs of wear, bulges, or uneven tread.
2. Remove any debris lodged in the tires that could cause friction.
3. Replace any damaged tires with new ones of the same size and specifications.

4. Inspect and Clean Engine Components

Sub-steps:
1. Check for any oil or fluid leaks that may have contacted hot engine parts.
2. Clean any residue using a degreaser and cloth.
3. Ensure all hoses and wires are secure and away from moving parts.
