Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Worn Components

Inspect the Serpentine Belt:
- Remove any covers obstructing access to the belt.
- Check for signs of wear like cracks or fraying.
- If damaged, use a socket set to loosen the tensioner and remove the old belt.
- Replace with a new serpentine belt, ensuring it is routed correctly.
Check and Replace Other Rubber Components:
- Inspect hoses (vacuum, coolant) for leaks or wear.
- Replace any hoses that show signs of cracking or leaking.

3. Address Brake System Issues

Inspect Brake Pads and Rotors:
- Remove the wheel to access the brake components.
- Check for excessive wear on pads and rotors.
- Replace any worn or damaged brake pads and rotors as necessary, following torque specifications when reinstalling.

4. Check Transmission Fluid

Inspect Transmission Fluid Level:
- Locate the transmission dipstick and check fluid level.
- If fluid is low, fill with the correct type of transmission fluid as specified in the owner’s manual.
- If the fluid is burnt (dark brown or has a burnt smell), consider a fluid change.

5. Clean Up Any Fluid Leaks

If any fluids were found leaking during the inspection, clean the affected areas to prevent further burning smells.
Ensure all connections are tight and secure to prevent leaks.
