Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working.

2. Inspect and Replace Fluid

Engine Oil:
- Remove the oil drain plug using a socket.
- Drain the oil into a container and replace it with new oil.
- Replace the oil filter if necessary.
- Torque the oil drain plug to manufacturer specifications (usually around 25-30 ft-lbs).
Transmission Fluid:
- Check the transmission fluid level using the dipstick.
- If low, drain and refill with the correct transmission fluid type as specified by the manufacturer.

3. Brake Inspection and Replacement

Remove the wheel to access the brake components.
Inspect brake pads and rotors for wear.
- If pads are less than 3mm thick, replace them.
- If rotors are warped or below the minimum thickness, replace them.
Reassemble the brakes, ensuring all components are properly torqued.

4. Replace Worn Belts or Hoses

Inspect belts for cracks or fraying; replace if necessary.
Check hoses for leaks or soft spots; replace if any issues are found.
Ensure all clamps are secure.

5. Reassemble and Test

Reconnect the battery.
Start the engine and allow it to idle for a few minutes.
Check for leaks and listen for any unusual noises.
Take the vehicle for a short test drive to verify the absence of burning smell.
