Solution

1. Preparation

Gather tools and safety gear (gloves, goggles).
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace the Serpentine Belt

Sub-steps:
1. Locate the serpentine belt routing diagram (usually found in the engine compartment).
2. Use a ratchet and socket to relieve tension on the belt by turning the tensioner pulley.
3. Remove the old belt and inspect all pulleys for damage or misalignment.
4. Install the new serpentine belt according to the routing diagram.
5. Reapply tension and ensure the belt is aligned properly on all pulleys.

3. Check Brake System Components

Sub-steps:
1. Remove the wheel covering the brake assembly.
2. Inspect brake pads for excessive wear and replace if necessary.
3. Check brake rotors for warping or overheating signs.
4. If the pads or rotors are damaged, replace them with new components.
5. Reassemble the wheel and lower the vehicle.

4. Inspect for Oil or Fluid Leaks

Sub-steps:
1. Clean any debris around the engine area to identify the source of leaks easily.
2. Check oil pan, gaskets, and seals for signs of leaks.
3. If leaks are found, replace the affected gaskets or seals.
4. Clean any spilled oil or fluid to prevent further burning smells.
5. Reconnect the negative battery terminal.
