Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during the process.

2. Inspect and Replace Serpentine Belt (if damaged)

Tools Required: Socket set, belt tensioner tool.
Sub-steps:

5. Reapply tension to the belt using the tensioner tool and ensure proper alignment.

3. Inspect and Replace Brake Components (if overheating)

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner.
Sub-steps:
1. Safely lift the vehicle using a jack and secure with jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect brake pads for signs of excessive wear or glazing; replace if necessary.
4. Check the brake calipers for signs of overheating or damage; replace if needed.
5. Clean the brake components with brake cleaner and reassemble.

4. Check for Fluid Leaks

Tools Required: Shop towels, flashlight.
Sub-steps:
1. Inspect under the vehicle for any fluid leaks that could be causing the burning smell.
2. Clean any leaks identified and replace any damaged hoses or seals.
3. Monitor the vehicle after repairs to ensure no further leaks occur.
