Solution

1. Preparation

Tools Required: OBD-II scanner, oil pressure gauge, socket set, torque wrench, oil catch pan.
Safety Warnings: Disconnect the battery before working on electrical components. Allow the engine to cool before opening any components.

2. Change Oil and Filter

Drain Old Oil: Place the oil catch pan under the oil pan and remove the drain plug. Allow old oil to fully drain.
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 filter and install it, ensuring it is hand-tight.
Install Drain Plug: Reinstall and torque the drain plug to the manufacturer's specification (usually around 25 ft-lbs).
Add New Oil: Pour the recommended type and amount of engine oil into the engine (check owner's manual for specifications).

3. Replace or Repair Oil Pump (if necessary)

Remove Oil Pan: Drain any remaining oil and remove the oil pan by unscrewing the bolts. Use a gasket scraper to clean the mating surfaces.
Inspect Oil Pump: Remove the oil pump from its housing. Check for wear or damage, and replace if necessary.
Install New Oil Pump: If replacing, install the new oil pump according to the manufacturer's specifications. Ensure it is properly aligned and secured.
Reinstall Oil Pan: Clean the oil pan gasket surface and install a new gasket. Reinstall the oil pan and torque bolts to the manufacturer's specification.
