Solution

1. Preparation

Gather tools required for inspection and repair, including a socket set, jack and jack stands, and safety goggles.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace the Serpentine Belt

Remove the Belt: Use a socket wrench to relieve tension on the tensioner pulley and slide the serpentine belt off.
Inspect the Belt: Check for cracks, fraying, or signs of glazing on the belt surface.
Replace the Belt: If damaged, install a new serpentine belt, ensuring it is properly routed according to the diagram typically located on the engine cover.

3. Inspect Brakes and Replace Parts if Necessary

Remove Wheel: Use a jack to lift the vehicle and secure it with jack stands. Remove the wheel to access the brake assembly.
Inspect Brake Components: Check the brake pads, rotors, and calipers for signs of overheating or damage.
Replace Worn Components: If pads are worn down or rotors are discolored, replace them with new parts.

4. Check and Replace Engine Oil or Fluid

Inspect Fluid Levels: Check engine oil, transmission fluid, and coolant levels for any discrepancies.
Change Oil if Necessary: If oil is burnt or low, perform an oil change using the manufacturer-recommended oil type.

5. Check Electrical Components

Inspect Alternator and Accessories: If the alternator is causing the smell, disconnect it, and inspect for wear.
Replace Defective Parts: If any electrical component is found to be faulty, replace it accordingly.
