Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery to prevent electrical shorts during inspection.

2. Inspect and Repair Engine Components

Inspect for Leaks:
- Check all hoses, seals, and connections in the engine compartment for leaks.
- Tighten any loose connections and replace damaged hoses.
Replace Damaged Components:
- If any burnt components (e.g., wiring, sensors) are found, replace them accordingly.
- Use manufacturer-approved parts to ensure compatibility.

3. Brake System Inspection and Repair

Remove Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel to access the brake assembly.
Inspect Brake Pads and Rotors:
- Check for excessive wear on brake pads and signs of overheating on rotors.
- Replace brake pads if they are worn down or if the rotors are scored or warped.

4. Exhaust and Transmission Fluid Check

Inspect Exhaust System:
- Look for signs of damage or signs of burning on exhaust pipes and catalytic converter.
- Replace any damaged sections of the exhaust system.
Check Transmission Fluid:
- Remove the transmission dipstick and inspect fluid for color and smell.
- If burnt, drain and replace the transmission fluid, ensuring to use the recommended type.
