Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Allow the engine to cool if it has recently been running.

2. Fluid Inspection and Replacement

Check oil level and condition:
- Remove the dipstick, wipe it clean, reinsert, and remove again to check the oil level.
- If oil is low or dirty, drain and replace with manufacturer-recommended oil (SAE 5W-20).
- Tools: Oil filter wrench, socket set, oil catch pan, funnel.
Inspect and refill other fluids:
- Check coolant level in the reservoir; top off with a 50/50 mix of coolant and distilled water if low.
- Check brake fluid level; replace if it appears dark or contaminated.

3. Brake System Inspection

Remove the wheel to inspect brake components:
- Check brake pads for excessive wear; replace if less than 3mm thick.
- Inspect rotors for warping or scoring; replace if necessary.
- Tools: Jack and jack stands, lug wrench, socket set.
- Safety Warning: Always use jack stands when the vehicle is elevated.

4. Belt and Hose Inspection

Visually check belts for cracks, fraying, or glazing.
- If damaged, remove the old belt and install a new one.
- Tools: Socket set, belt tensioner tool.
Inspect hoses for leaks or bulges; replace any that show signs of wear.
- Tools: Hose clamp pliers.

5. Tire Inspection

Check tires for uneven wear patterns or overheating.
- Rotate or replace tires as necessary based on inspection findings.
- Tools: Tire pressure gauge, lug wrench.
