Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues during repairs.

2. Check and Top Off Oil Level

Locate the oil dipstick, remove it, and wipe it clean.
Reinsert the dipstick, pull it out again to check the oil level.
If low, add the appropriate type and grade of engine oil as specified in the owner's manual.

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 gasket of the new filter.
Install the new oil filter and tighten it according to specifications (usually hand-tight plus a quarter turn).

4. Inspect and Replace Oil Pump (if necessary)

Remove the oil pan by unscrewing the bolts holding it in place.
Take out the old oil pump, inspect it for damage or wear.
Install the new oil pump, ensuring it is properly aligned and secured.
Reattach the oil pan with a new gasket, torquing the bolts to the manufacturer’s specifications.

5. Check for Oil Leaks

After reassembly, fill the engine with oil to the proper level.
Start the engine and let it idle, checking for any leaks around the oil filter and oil pan.
Monitor the oil pressure gauge to ensure it operates within the normal range.
