Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Inspect and Replace Worn Components

Inspect Belts and Hoses:
- Look for frays, cracks, or signs of wear.
- If damaged, loosen the belt tensioner and remove the worn belt. Replace with a new belt, ensuring proper routing.
Inspect Electrical Wiring:
- Check for damaged insulation or burnt wires.
- Replace any damaged wiring with appropriate gauge wire and connectors.

3. Fluid Replacement

Engine Oil:
- If oil is burnt, drain the old oil using an oil catch pan. Replace with new oil of the appropriate grade as specified in the owner's manual.
- Replace the oil filter using an oil filter wrench.
Coolant:
- If coolant is low or contaminated, drain the old coolant from the radiator. Flush the system with water if necessary.
- Refill with the correct type of coolant as specified by the manufacturer.

4. Additional Checks

Inspect for Leaks:
- After addressing any issues, check for leaks by running the engine and observing all components.
Test Drive:
- Conduct a test drive to ensure that the burning smell has dissipated and no new symptoms arise.
