Solution

1. Preparation

Tools Required: Safety gloves, safety goggles, flashlight, OBD-II scanner.
Park the vehicle on a flat surface and allow it to cool down before inspecting under the hood.

2. Addressing Fluid Leaks

Sub-steps:
1. Identify the type of fluid leaking (e.g., oil, coolant, transmission fluid).
2. If the leak is from coolant, check the radiator and hoses for damage and tighten any loose connections.
3. For oil leaks, inspect the oil filter and drain plug for tightness and replace any faulty seals.

3. Belts and Hoses Replacement

Sub-steps:
1. Remove any covers to access belts and hoses.
2. Inspect each belt for cracks or signs of wear; replace if necessary.
3. Check hoses for softness or leaks; replace damaged hoses with OEM or high-quality aftermarket parts.

4. Brake Inspection and Repair

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect the brake pads and rotors for excessive wear; replace if pads are worn down or if rotors are damaged.
3. Ensure calipers are functioning properly and not sticking.

5. Oil Change (if necessary)

Sub-steps:
1. If the oil is low or has a burnt smell, prepare to change the oil.
2. Drain the engine oil using a wrench on the oil pan drain plug.
3. Replace the oil filter using an oil filter wrench.
4. Refill with the manufacturer-recommended engine oil.
