Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, multimeter, inspection light
Safety Warnings: Ensure the engine is cool before starting work. Disconnect the battery to avoid electrical shock.

2. Address Fluid Leaks

Sub-steps:
1. Identify and locate the source of any fluid leaks (oil, coolant, etc.).
2. Clean the area with a degreaser to prevent further burning smells.
3. Replace any damaged gaskets, seals, or hoses that are leaking.

3. Replace Worn Belts or Hoses

Sub-steps:
1. Remove the serpentine belt using a socket wrench to relieve tension.
2. Inspect the belt for cracks or signs of wear and replace if necessary.
3. Inspect hoses for bulges or cracks; replace any damaged hoses.

4. Brake System Inspection and Repair

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for wear; replace if they are worn down to the metal.
3. Check for overheating signs on the rotors; resurface or replace as needed.

5. Electrical System Check

Sub-steps:
1. Use a multimeter to test the battery voltage; should read around 12.6 volts when the engine is off.
2. Start the engine and check the alternator output; should read between 13.7 to 14.7 volts.
3. Replace any faulty wiring or components that are causing electrical shorts.
