Solution

1. Preparation

Gather necessary tools and parts before starting.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical issues during repairs.

2. Check and Top Off Engine Oil

Remove the oil filler cap.
Use a funnel to add the correct type and amount of oil if low (consult owner's manual for specifications).
Replace the oil filler cap securely.

3. Replace Oil Filter

Locate the oil filter and use an oil filter wrench to remove it.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand, tightening it according to the specifications (usually around 3/4 turn after gasket contact).

4. Inspect and Replace Oil Pump (if necessary)

Drain the engine oil completely using a drain pan.
Remove the oil pan by unscrewing the bolts and carefully prying it off.
Disconnect the oil pump from the engine block following the manufacturer's guidelines.
Install the new oil pump, ensuring it is aligned properly and secured with bolts to the specified torque values.
Reinstall the oil pan and replace the oil drain plug.

5. Final Checks

Refill the engine with the appropriate type and amount of oil.
Reconnect the battery.
Start the engine and let it idle, checking for leaks and listening for unusual noises.
