Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, oil filter wrench, clean rags, new oil, and a new oil filter.
Ensure the vehicle is parked on a level surface and the engine is turned off and cooled.

2. Address Oil Leaks

Sub-step 2.1: If leaks are found, clean the area around the leak with rags.
Sub-step 2.2: Tighten any loose bolts or connections related to the oil filter or oil pan.
Sub-step 2.3: If necessary, replace the oil filter. Use an oil filter wrench to remove the old filter and install the new one, ensuring the rubber O-ring is lubricated with new oil before installation.

3. Oil Change

Sub-step 3.1: Drain the old oil by removing the drain plug using a socket set. Allow the oil to fully drain into a suitable container.
Sub-step 3.2: Replace the drain plug and torque it to the manufacturer’s specifications.
Sub-step 3.3: Add new oil through the oil filler cap, using the correct type and amount as specified in the owner's manual.

4. Monitor and Test

After completing the repairs, run the engine for a few minutes and check for leaks around the oil filter and drain plug.
Use the OBD-II scanner to clear any error codes and monitor oil levels over the next few days.
