Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Safety: Disconnect the battery before starting any work.

2. Add Engine Oil

Locate the oil filler cap on the engine.
Remove the oil filler cap and place a funnel in the opening.
Pour the recommended engine oil (check owner's manual for specifications) into the funnel.
Add oil gradually, checking the dipstick frequently to avoid overfilling.

3. Inspect and Repair Leaks

If leaks are found during the diagnostic steps, note their locations.
Clean the area around the leak with a degreaser.
Replace any damaged gaskets or seals that may be causing the leaks.
Tighten any loose connections or fittings.

4. Replace Oil Filter (if necessary)

If the oil filter is leaking or has not been changed recently:
- Use an oil filter wrench to remove the old oil filter.
- Apply a small amount of fresh oil to the rubber gasket of the new filter.
- Install the new oil filter by hand, ensuring it is snug but not overly tight.

5. Final Checks

Reinstall the oil filler cap securely.
Start the engine and let it run for a few minutes, checking for leaks.
Turn off the engine and check the oil level again, adding oil if necessary.
