- Open the hood and locate the dipstick for engine oil; pull it out, clean it with a rag, and reinsert it to check the level.
- Check coolant level in the reservoir; if low, add the appropriate coolant type as specified in the owner's manual.
- Inspect brake fluid level; if low, add the recommended brake fluid.
Tools Required: None
Safety Warnings: Always allow the engine to cool before checking coolant levels.

3. Inspect for Leaks

Sub-steps:
- Look under the engine and transmission for any signs of fluid leaks.
- Inspect hoses and connections for wear or damage.
- Check the oil filter and drain plug for signs of oil leakage.
Tools Required: Flashlight for better visibility
Safety Warnings: Ensure the engine is off and cool before inspecting for leaks.

4. Visual Inspection of Engine Components
