Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Inspect and Correct Oil Filter Installation

Locate the oil filter on the engine.
Use an oil filter wrench to remove the oil filter carefully.
Inspect the rubber O-ring on the old filter; ensure it has been removed and is not stuck to the engine.
Install a new oil filter, applying a small amount of oil to the O-ring for a proper seal.
Torque the new filter to the manufacturer's specifications (typically hand-tight plus a quarter turn).

3. Check and Adjust Oil Level

Remove the oil dipstick and wipe it clean.
Reinsert the dipstick fully, then remove it again to check the oil level.
If low, add the appropriate type of oil specified in the owner's manual until it reaches the correct level.

4. Verify Engine Oil Cap

Locate the engine oil cap and ensure it is properly seated.
If it is loose or missing, replace it and secure it tightly.

5. Reconnect Battery

Reconnect the battery terminals securely after completing the checks and adjustments.
