Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Gather tools and parts needed for inspection and repair.

2. Check and Replace Engine Oil

Remove the oil dipstick and check oil level and condition.
If the oil is low or has a burnt smell, drain the old oil using an oil pan.
Replace with manufacturer-recommended engine oil using a funnel.
Replace the oil filter if it shows signs of contamination or wear.

3. Brake System Inspection

Remove the wheel to access the brake components.
Inspect brake pads and rotors for excessive wear or overheating.
Replace worn brake pads or rotors as necessary; ensure proper torque on bolts (typically 80-100 ft-lbs).
Reassemble the wheel and lower the vehicle.

4. Electrical System Check

Inspect the wiring harness for any melted insulation or burnt connectors.
Replace damaged wires or connectors with OEM parts.
Use electrical tape or heat-shrink tubing to insulate repaired areas.

5. Exhaust System Examination

Inspect the exhaust manifold, catalytic converter, and pipes for damage or leaks.
Tighten loose connections or replace damaged sections of the exhaust system.
Ensure all clamps and hangers are secure.
