Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Safety: Disconnect the negative terminal of the battery to prevent electrical issues.

2. Check and Top Off Engine Oil

Locate the engine oil dipstick.
Remove the dipstick, wipe it clean, and reinsert it fully.
Pull it out again and check the oil level; if below the "Add" mark, add the appropriate engine oil (5W-30 recommended).
Recheck the oil level after adding oil.

3. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber seal of the new filter.
Install the new oil filter by hand tight, then give it an additional 3/4 turn.
Ensure the area around the oil filter is clean before installation.

4. Oil Pump Inspection

Drain the engine oil using a drain pan by removing the drain plug with a socket wrench.
Inspect the oil pump for any signs of damage or wear.
If damaged, remove the oil pump by unbolting it from the engine and replace with a new pump.
Reinstall the drain plug with the specified torque (typically around 20 ft-lbs).

5. Refill Engine Oil

Use a funnel to refill the engine with new oil through the oil filler cap.
Start the engine and allow it to run for a few minutes, then check for leaks.

6. Final Checks

Reconnect the battery terminal.
Start the engine and check for the oil pressure warning light.
Listen for abnormal engine noises.
