Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent accidental electrical shorts.

2. Check and Top Off Engine Oil

Remove the oil filler cap.
Using a funnel, add the appropriate type and amount of oil as specified in the owner’s manual.
Reinstall the oil filler cap securely.

3. Replace Oil Filter (if necessary)

Use an oil filter wrench to remove the old oil filter.
Lubricate the rubber O-ring of the new oil filter with a little new oil.
Install the new oil filter by hand until it is snug, then tighten it according to the manufacturer’s specifications.

4. Inspect and Replace Oil Pump (if faulty)

Drain the engine oil and remove the oil pan by loosening the bolts using a socket set.
Remove the old oil pump from its mounting location.
Install the new oil pump, ensuring proper alignment and sealing.
Reattach the oil pan and torque the bolts to the manufacturer's specifications.

5. Final Checks

Refill the engine with new oil according to specifications.
Reconnect the battery.
Start the engine and allow it to run for a few minutes to circulate the oil.
