Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, coolant tester, flashlight, rags.
Ensure the vehicle is on a level surface and the engine is cool before starting work.

2. Identify Source of Burning Smell

Sub-steps:
1. Fluid Inspection: Check for oil, coolant, or transmission fluid leaks. Clean any spills to prevent further burning smells.
2. Belt and Hose Inspection: Visually inspect all belts and hoses for signs of wear or damage. Replace any that are frayed or cracked.
3. Brake Component Check: Inspect brake pads and rotors for overheating. If pads are worn, replace them. Ensure calipers are functioning properly and not sticking.

3. Address Detected Issues

Sub-steps:
1. Fluid Replacement: If any fluid is burnt or low (oil/transmission fluid), drain and replace with manufacturer-recommended fluids.
2. Belt Replacement: If any belts are damaged, use a socket set to remove the old belt and install a new one, ensuring proper tension.
3. Brake Pad Replacement: Remove the wheel and caliper to access the brake pads. Replace with new pads, ensuring proper fit and torque specifications for caliper bolts.

4. Final Check

Sub-steps:
1. Start the engine and let it run for a few minutes, checking for any new smells or leaks.
2. Monitor the temperature gauge to ensure the engine is operating within normal limits.
