Solution

1. Preparation

Gather tools and materials: oil filter wrench, socket set, oil pressure gauge, new oil, new oil filter, funnel, rags for cleanup.
Ensure the vehicle is parked on a level surface and the engine is off and cool.

2. Check and Top Off Oil Level

Open the hood and locate the oil fill cap.
Remove the cap and use a funnel to add oil if the level is low. Refer to the owner’s manual for the correct oil type and specifications.
Replace the oil fill cap securely.

3. Replace Oil Filter

Locate the oil filter and use an oil filter wrench to remove it.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand, ensuring it is snug but not overly tight.

4. Change Oil

Place a drain pan underneath the oil pan.
Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
Replace the drain plug and tighten it to the manufacturer’s torque specifications.
Fill the engine with the appropriate amount of new oil through the oil fill cap.

5. Test Oil Pressure

Connect a mechanical oil pressure gauge to the oil pressure sending unit port.
Start the engine and observe the gauge for oil pressure readings. Compare with manufacturer specifications.
If pressure is low, further investigation into the oil pump and related components may be necessary.
