Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cooled down.
Disconnect the battery to prevent electrical issues while working.

2. Check and Top Off Engine Oil

Sub-steps:
1. Remove the dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the oil level.
3. If low, add the correct grade of oil (refer to the owner’s manual for specifications).
4. Start the engine and let it idle for a few minutes, then recheck the oil level.

3. Inspect and Replace Oil Filter

Sub-steps:
1. Locate the oil filter (usually at the bottom of the engine).
2. Use an oil filter wrench to remove the old filter.
3. Apply a thin layer of new oil to the rubber gasket of the new filter.
4. Install the new oil filter and tighten it per manufacturer's specifications (usually hand-tight plus a quarter turn).

4. Check and Replace Oil Pump (if necessary)

Sub-steps:
1. If low oil pressure persists, drain the engine oil.
2. Remove the oil pan to access the oil pump.
3. Disconnect any electrical connectors and remove mounting bolts of the oil pump.
4. Replace the old oil pump with a new one, ensuring proper alignment and securing with bolts to manufacturer specifications.
5. Reinstall the oil pan with a new gasket and torque to specifications.

5. Refill Engine Oil

Sub-steps:
1. Add new engine oil through the oil filler cap, using the correct oil type and amount.
2. Start the engine and allow it to run for a few minutes.
3. Check for leaks around the oil filter and oil pan.
