Solution

1. Preparation

Gather tools and materials:
- Wrench set
- Oil pressure gauge
- New oil filter (if replacing)
- Engine oil (manufacturer's recommended type)
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Add Engine Oil

Locate the oil dipstick and remove it.
Wipe it clean, then reinsert and remove it again to check the oil level.
- If low:
  - Remove the oil filler cap.
  - Add the correct type of engine oil as specified in the owner's manual.
  - Recheck the oil level after adding.

3. Inspect for Oil Leaks

Visually inspect the engine and undercarriage for signs of oil leaks.
If leaks are found, identify the source (gasket, seal, or oil filter).
Replace any damaged gaskets or seals as necessary.

4. Test Oil Pressure

Remove the oil pressure sending unit using the appropriate wrench.
Install the oil pressure gauge in its place.
Start the engine and observe the oil pressure reading.
- Normal pressure: 25-65 psi (check manual for specific values).
- If low:
  - Inspect the oil pump for failure or blockage.
  - Consider replacing the oil pump if necessary.

5. Replace Oil Filter (if applicable)

Use an oil filter wrench to remove the old oil filter.
Apply a little new oil to the rubber gasket of the new filter.
Install the new oil filter, ensuring it is snug but not over-tightened.
