Solution

1. Preparation

Tools Required: OBD-II scanner, infrared thermometer, fluid catch pan, basic hand tools (sockets, wrenches).
Safety Warnings: Ensure the vehicle is parked on a level surface and the engine is cool before starting work.

2. Address Fluid Leaks

Sub-step 1: If oil is leaking, identify the source (e.g., oil filter, oil pan gasket) and replace the faulty component.
Sub-step 2: If coolant is leaking, inspect hoses and the radiator for cracks and replace any damaged parts.
Sub-step 3: Refill any lost fluids to the appropriate levels.

3. Replace Worn Components

Sub-step 1: If belts are worn or damaged, remove the old belt by loosening the tensioner and replace it with a new one. Torque to specifications.
Sub-step 2: Replace any damaged hoses with OEM parts, ensuring all clamps are secure after installation.

4. Clean and Inspect Brakes

Sub-step 1: Remove the wheel and inspect brake pads for wear; replace if necessary.
Sub-step 2: Clean the brake calipers and ensure they are not sticking; lubricate moving parts as needed.

5. Final Checks

Sub-step 1: Start the engine and allow it to reach operating temperature while monitoring for any continued burning smell or leaks.
Sub-step 2: Test drive the vehicle to ensure all repairs were successful and no new symptoms arise.
