Solution

1. Preparation

Gather all necessary tools and parts.
Make sure the engine is cool before beginning work.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Change Engine Oil and Filter

Lift the Vehicle: Use a jack and jack stands to elevate the front of the vehicle securely.
Drain Oil: Remove the oil drain plug with a socket wrench and allow the old oil to drain fully into an oil pan.
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 oil filter.
- Install the new oil filter by hand, tightening it according to manufacturer specifications.
Reinstall Drain Plug: Replace and tighten the oil drain plug to manufacturer torque specifications.

3. Inspect and Replace Oil Pump (if necessary)

Access the Oil Pump: Remove components obstructing access to the oil pump, typically the oil pan and possibly the front of the engine.
Remove Oil Pump: Unbolt the oil pump from the engine block and detach it from the oil pickup tube.
Install New Oil Pump: Position the new oil pump and securely bolt it in place, adhering to torque specifications.
Reassemble: Reinstall the oil pan along with any removed components, ensuring all gaskets are correctly positioned.

4. Verify Oil Pressure

Reconnect the Battery: Reattach the negative battery terminal.
Start the Engine: Allow the engine to reach operating temperature while monitoring oil pressure.
Use Oil Pressure Gauge: Confirm that oil pressure is within the acceptable range using the mechanical gauge.
