Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical issues during inspection.

2. Inspect and Replace Belts

Tools Required: Socket set, belt tensioner tool
Sub-steps:
1. Remove the engine cover if necessary.
2. Inspect the serpentine belt for cracks, fraying, or wear. If damaged, proceed to replace.
3. Loosen the belt tensioner and remove the old belt.
4. Install the new serpentine belt according to the routing diagram.
5. Tighten the tensioner back to specifications.

3. Inspect and Replace Brake Components

Tools Required: Jack and jack stands, socket set, torque wrench
Sub-steps:
1. Safely lift the vehicle and remove the front or rear wheels.
2. Inspect brake pads for excessive wear or burning. Replace if necessary.
3. Inspect brake rotors for glazing or warping; replace if needed.
4. Reassemble the brakes and wheels, ensuring all bolts are torqued to manufacturer specifications.

4. Inspect Tires

Tools Required: Tire pressure gauge
Sub-steps:
1. Check tire pressure and ensure it matches the manufacturer's recommended PSI.
2. Inspect tires for uneven wear patterns indicating alignment issues. If present, schedule an alignment.
3. Replace any damaged tires that may be contributing to the smell.

5. Verify Transmission Fluid

Tools Required: Transmission fluid dipstick, funnel
Sub-steps:
1. Locate the transmission dipstick and check the fluid level.
2. Inspect the fluid for a burnt smell or dark color, indicating it needs to be replaced.
3. If low or degraded, drain and replace the transmission fluid with the specified OEM type.
