Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical hazards.

2. Inspect and Clean Components

Engine Oil
- Remove the oil dipstick and check the level and condition.
- If burnt, drain the oil using an oil pan and replace it with fresh oil.
Coolant System
- Check the coolant reservoir and radiator for leaks.
- If low, refill with the appropriate coolant mixture (50/50 mix of coolant and distilled water).
- Inspect hoses for cracks or damage, replacing any as necessary.

3. Brake System Inspection

Remove the wheel to access the brake components.
Inspect the brake pads and rotors for excessive wear or burning.
Replace brake pads if they are worn down or damaged.

4. Transmission Fluid Check

Locate the transmission dipstick and remove it to check fluid level.
If the fluid is burnt or low, drain the old fluid and replace it with new transmission fluid (refer to manufacturer specifications for type and quantity).

5. Reassembly and Fluid Replacement

Reinstall any components removed during inspection.
Reconnect the battery and ensure all tools are removed from the engine bay.
