Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, brake cleaner, and multimeter.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery for safety before working on electrical components.

2. Inspect and Clean Engine Components

Check for Leaks: Visually inspect the engine for oil, coolant, or other fluid leaks. Clean any spilled fluids with brake cleaner.
Replace Worn Components: If leaks are found, replace the affected gaskets, seals, or hoses. Torque specifications can be found in the vehicle's service manual.

3. Brake Inspection and Replacement

Remove Wheel: Use a jack to lift the vehicle and remove the wheel where the burning smell is suspected.
Inspect Brake Pads and Rotors: Check the thickness of the brake pads and the surface of the rotors for scoring or warping.
- If pads are below manufacturer specifications, replace them.
- If rotors are damaged, replace or resurface them as necessary.
Reassemble: Reinstall the wheel, lower the vehicle, and torque the lug nuts to the manufacturer's specifications.

4. Coolant System Check

Inspect Coolant Levels: Check the coolant reservoir and radiator for proper fluid levels.
Replace Cap or Hose: If the cap is damaged or hoses are leaking, replace them accordingly.
Flush System: If the coolant is contaminated, perform a complete coolant flush and refill with the recommended fluid.
