Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Check and Top Off Engine Oil

Remove the oil filler cap.
Use a funnel to add the appropriate type of oil (consult the owner’s manual for specifications).
Replace the oil filler cap securely.

3. Replace Oil Filter

Locate the oil filter; 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 until snug, then tighten an additional three-quarters of a turn.

4. Inspect and Replace Oil Pump (if necessary)

Drain the engine oil completely by removing the oil drain plug.
Remove the oil pan by unscrewing the bolts; clean the sealing surfaces.
Remove the old oil pump by detaching it from the engine block (may require removing the timing cover).
Install the new oil pump, ensuring proper alignment and sealing.
Reinstall the oil pan with a new gasket, torquing bolts to manufacturer specifications.

5. Refill Engine Oil

Replace the drain plug securely.
Refill the engine with the correct amount and type of oil.
Start the engine and let it idle for a few minutes, checking for leaks.
