Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is cool before starting work.

2. Inspect and Replace Worn Components

Belts and Hoses:
1. Remove the engine cover if applicable (use socket set).
2. Visually inspect all belts and hoses for cracks, fraying, or wear.
3. Replace any damaged belts or hoses with OEM parts.
Brake System:
1. Raise the vehicle and secure it on jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect brake pads and rotors for excessive wear or damage.
4. Replace worn brake pads or rotors as necessary.
5. Reassemble the wheel and lower the vehicle.

3. Address Fluid Leaks

Engine Oil:
1. Locate the source of any oil leaks.
2. Tighten any loose bolts or replace gaskets as necessary.
3. Clean the area to prevent future build-up, ensuring no oil drips onto hot components.
Transmission Fluid:
1. Check the transmission fluid level using the dipstick.
2. If low, add the appropriate type of transmission fluid (refer to owner's manual).
3. If fluid is burnt or discolored, consider a transmission flush and filter replacement.

4. Final Checks

Reassemble any components that were removed during the inspection.
Start the engine and let it idle; check for any leaks or abnormal noises.
Test drive the vehicle to ensure the burning smell is no longer present.
