Solution

1. Preparation

Tools Required: Safety goggles, gloves, jack and jack stands, wheel chocks, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is cool before starting the inspection.

2. Inspect and Replace Brake Components

Sub-steps:
1. Lift the Vehicle: Use a jack to raise the vehicle and secure it with jack stands.
2. Remove Wheel: Take off the wheel to access brake components.
3. Examine Brake Pads and Rotors: Inspect for wear; replace if pads are less than 3mm thick or if rotors are scored.
  - Tools Required: Socket set, brake pad spreader.
4. Install New Brake Pads: If replacement is necessary, remove old pads and install new ones according to the manufacturer’s specifications, ensuring caliper bolts are torqued to the recommended value (typically around 25 Nm).
5. Reassemble Wheel and Lower Vehicle: Reattach the wheel and lower the vehicle back to the ground.

3. Check Engine Components

Sub-steps:
1. Check for Oil Leaks: Inspect the engine for oil leaks that may cause burning when heated.
2. Inspect Belts and Hoses: Look for signs of wear or damage; replace if cracked or frayed.
  - Tools Required: Visual inspection, hands for manipulation.
3. Examine Electrical Wires: Ensure all wiring is intact and not exposed to heat sources; repair or replace damaged wires.

4. Flush Coolant System (if overheating)

Sub-steps:
1. Drain Old Coolant: Remove the drain plug at the bottom of the radiator and allow the old coolant to drain completely.
2. Flush System: Use a coolant flush solution and fill with water to flush out debris; run the engine until warm, then drain again.
3. Refill with New Coolant: Replace with the manufacturer-specified coolant mixture (typically 50/50) and check for leaks.
