Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts while working.

2. Inspect and Clean Engine Components

Tools Required: Socket set, ratchet, cleaning rags
Remove engine covers if necessary to access components.
Inspect for oil leaks around the valve cover gasket and oil pan.
Clean any spilled oil or fluid with rags to prevent further burning smells.

3. Brake Inspection and Replacement

Tools Required: Jack, jack stands, lug wrench, torque wrench
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads for wear and replace them if they are below the minimum thickness.
Check the brake rotors for scoring or damage and replace if necessary.
Reassemble the brake components and lower the vehicle. Torque the wheel bolts to manufacturer specifications.

4. Electrical System Inspection

Tools Required: Multimeter, electrical contact cleaner
Inspect all wiring and connectors under the hood for signs of wear or melting.
Use a multimeter to check for continuity in any suspect wiring.
Clean corroded connections with electrical contact cleaner and reconnect securely.

5. Coolant System Check

Tools Required: Coolant pressure tester
Check the coolant level in the reservoir and radiator.
Use a coolant pressure tester to check for leaks in the system.
Replace any damaged hoses or components and refill the system with the appropriate coolant type.
