Solution

1. Preparation

Gather necessary tools and parts.
Park vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Inspect Oil Level and Quality

Remove the dipstick and wipe it clean.
Reinsert and remove the dipstick again to check the oil level.
If oil level is low, top up with the correct oil type and viscosity.
If oil appears dirty or has metal shavings, consider an oil change.

3. Inspect Oil Filter

Use an oil filter wrench to remove the oil filter.
Check the rubber O-ring on the old filter; if it’s stuck to the engine, replace it.
Install a new oil filter, ensuring it is properly seated and tightened (hand-tight plus ¾ turn).

4. Check for Leaks

Inspect the oil drain plug for proper torque (usually 20-25 lb-ft).
Look around the oil filter and drain plug for any signs of leaks.
Clean any spilled oil and monitor for reoccurrence.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any trouble codes that may have been triggered.
Start the engine and monitor for the check engine light.
