Write down any codes for reference.

3. Inspect Oil Level and Quality

Open the hood and remove the dipstick.
Clean it with a rag, reinsert, and then remove it again to check the oil level.
Ensure the oil is at the correct level and appears clean (not dark or dirty).

4. Check Oil Filter Installation

Use the oil filter wrench to remove the oil filter.
Inspect the rubber O-ring for damage or debris.
Reinstall or replace the oil filter, tightening it according to the manufacturer’s specifications (usually hand-tight plus 1/4 turn).

Ensure the oil fill cap is properly secured.
Inspect surrounding electrical connections for any loose, damaged, or corroded wires.
Clean any corrosion or dirt from the connections.
