Solution

1. Preparation

Gather tools: socket set, wrench set, OBD-II scanner, flashlight, and shop towels.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Change Engine Oil

Sub-steps:
1. Remove the dipstick and check the oil level; add oil if it is low.
2. If the oil appears burnt (dark and has a burnt smell), prepare to change it.
3. Place an oil catch pan underneath the oil pan, remove the drain plug, and allow the old oil to drain completely.
4. Replace the drain plug and torque it to the manufacturer's specifications (typically around 20-25 ft-lbs).
5. Replace the oil filter with a new one, ensuring the rubber O-ring is lubricated and the old filter is removed.
6. Refill the engine with new oil (check the owner's manual for the correct type and capacity).

3. Inspect and Replace Brake Components

Sub-steps:
1. Jack up the vehicle and remove the wheels for access to the brake system.
2. Inspect the brake pads for signs of excessive wear or glazing. Replace if necessary.
3. Check the brake rotors for warping or overheating; resurface or replace if needed.
4. Reinstall the wheels and lower the vehicle.

4. Inspect Serpentine Belt and Rubber Components

Sub-steps:
1. Visually inspect the serpentine belt for cracks, fraying, or signs of glazing.
2. If damaged, remove the belt by loosening the tensioner and replacing it with a new one.
3. Check other rubber components (hoses, grommets) for wear and replace as necessary.
