Solution

1. Preparation

Tools Required: Safety glasses, gloves, flashlight, OBD-II scanner, jack and jack stands
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Replace Worn Belts

Sub-steps:
1. Open the hood and visually inspect the serpentine and timing belts for cracks, fraying, or signs of wear.
2. If any damage is found, loosen the tensioner and remove the old belt.
3. Install the new belt by following the routing diagram typically located near the radiator or on the belt itself.
4. Adjust the tensioner to maintain appropriate tension on the new belt.

3. Check and Replace Tires (if necessary)

Sub-steps:
1. Inspect all tires for uneven wear patterns, bulges, or other damage.
2. If tires are worn out, remove the old tires using a jack and socket wrench.
3. Install new tires, ensuring they are balanced and aligned according to manufacturer specifications.

4. Brake System Inspection

Sub-steps:
1. Inspect the brake pads and rotors for excessive wear or damage.
2. If the brake pads are worn, remove the wheel and replace the pads.
3. Check the brake calipers for proper function; replace if they are sticking or damaged.
