Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and allow the engine to cool.
Disconnect the negative battery terminal for safety.

2. Check and Replace Engine Oil

Remove the oil filler cap.
Use a dipstick to check the oil level; add the appropriate type and grade of oil if low.
If oil is contaminated, drain the old oil using a drain pan:
- Remove the oil drain plug using a socket.
- Allow the oil to fully drain.
Replace the drain plug and torque to manufacturer specifications (check owner’s manual).

3. Replace Oil Filter

Locate the oil filter.
Using an oil filter wrench, remove the old oil filter.
Apply a thin layer of fresh oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand, tightening it according to specifications.

4. Inspect and Replace Oil Pressure Sending Unit (if necessary)

Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector.
Remove the sending unit with a socket.
Install a new oil pressure sending unit and connect the electrical connector.

5. Test Oil Pressure

Install a mechanical oil pressure gauge in place of the oil pressure sending unit.
Start the engine and observe the gauge reading.
If the pressure is within specifications, reinstall the sending unit; if low, further investigation is needed (potential oil pump failure).

6. Reconnect Battery

Reconnect the negative battery terminal.
