Solution

1. Preparation

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

2. Check and Top Off Oil Level

Remove the dipstick and wipe it clean.
Insert the dipstick back into the tube and remove it again to check the oil level.
- If low, add the manufacturer-recommended oil until the correct level is reached.

3. Replace Oil Filter

Place an oil catch pan under the 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 oil filter.
Install the new oil filter by hand until snug, then tighten according to the manufacturer's specifications.

4. Change Engine Oil

Drain the existing oil by removing the drain plug with a socket set (ensure the catch pan is in place).
Allow all the old oil to fully drain out.
Replace the drain plug and tighten it to the specified torque value.
Refill the engine with the appropriate grade of oil as per the owner's manual.

5. Inspect Oil Pump

If low oil pressure persists, remove the oil pan to access the oil pump.
Inspect the oil pump for wear or damage; replace if necessary.
Ensure that all oil passages are clear and free of debris.
