Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Replace Engine Oil

Sub-steps:
- Remove the oil dipstick and check the oil level and condition.
- If oil is low or burnt, drain the old oil using a wrench to remove the oil drain plug.
- Replace with new oil according to manufacturer's specifications (e.g., 0W-20 for Honda).
- Install a new oil filter to ensure proper filtration.

3. Check and Replace Coolant

Sub-steps:
- Locate the coolant reservoir and check fluid levels.
- If low, add the recommended coolant type (typically a mix of 50/50 antifreeze and distilled water).
- Inspect hoses for leaks; replace any damaged hoses.
- Bleed the cooling system to remove air pockets if necessary.

4. Inspect and Replace Belts and Hoses

Sub-steps:
- Visually inspect all belts for cracks, fraying, or glazing.
- Use a belt tension gauge to check tension; replace if out of specification.
- Inspect hoses for leaks or bulges; replace any compromised hoses.

5. Brake Inspection

Sub-steps:
- Remove the wheel to access the brake components.
- Check brake pads for excessive wear; replace if necessary.
- Inspect calipers and rotors for overheating signs, and replace as needed.
