Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather tools and safety gear, including gloves and safety glasses.

2. Inspect and Replace Worn Components

Serpentine Belt Replacement
- Remove the engine cover if necessary.
- Use a socket set to loosen the tensioner and remove the old serpentine belt.
- Inspect the pulleys for wear and ensure they are spinning freely.
- Install the new serpentine belt according to the routing diagram located on the engine bay.
- Tighten the tensioner and replace any covers.
Tire Inspection and Rotation
- Check all tires for signs of excessive wear, punctures, or deformities.
- Rotate the tires if necessary, following the vehicle’s recommended pattern.
- Replace any damaged tires.
Fluid Leaks Repair
- Inspect for leaks using a flashlight; clean the area if necessary.
- Replace any damaged hoses or seals that may be causing leaks.
- Top off any low fluid levels (engine oil, coolant, transmission fluid).

3. Verify Component Function

After repairs, start the engine and allow it to reach operating temperature while observing for any unusual smells or noises.
Ensure all components are functioning properly and that the burning smell has dissipated.
