Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Change Engine Oil and Filter

Drain Old Oil
- Place an oil catch pan under the oil pan.
- Remove the oil drain plug using a socket set and allow the old oil to completely drain.
Replace Oil Filter
- Use an oil filter wrench to remove the old oil filter.
- Apply a thin layer of new oil to the rubber gasket of the new filter.
- Install the new oil filter by hand until snug, then tighten an additional 3/4 turn.
Add New Oil
- Replace the oil drain plug and torque to the manufacturer's specification (typically around 30 ft-lbs).
- Pour the recommended oil type (typically 0W-20 or 5W-20) into the engine through the oil filler cap, using the specified amount (approximately 4.4 quarts).
Check Oil Level
- Wait for a few minutes, then check the oil level with the dipstick. Add oil if necessary.

3. Inspect Oil Pump and Pressure Relief Valve

Remove Oil Pump
- If low oil pressure persists, remove the oil pan and inspect the oil pump.
- Unbolt the oil pump from the engine block and check for wear and proper operation.
Check Pressure Relief Valve
- Inspect the oil pressure relief valve for blockage or malfunction. Clean or replace if necessary.
