Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Socket set, oil pressure gauge, torque wrench, OBD-II scanner, oil filter wrench.
Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool.

2. Change Engine Oil and Filter

Drain Old Oil:
- Place a drain pan under the oil pan.
- Remove the oil drain plug and allow the old oil to drain completely.
- Replace the drain plug and torque to manufacturer specifications (usually around 25 Nm).
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket of the new filter with fresh oil.
- Install the new oil filter and tighten it by hand (do not over-tighten).
Add New Oil:
- Refer to the owner’s manual for the correct oil type and capacity (usually around 5-6 quarts of synthetic oil).
- Pour new oil into the engine through the oil filler cap.

3. Check and Repair Oil Pump

Remove Oil Pump:
- Drain the oil again if necessary.
- Remove components obstructing access to the oil pump (like the oil pan).
- Unbolt the oil pump and remove it from the engine.
Inspect Oil Pump:
- Check the pump for wear or damage.
- Replace the oil pump if it is not functioning properly.

4. Reassemble and Test

Reinstall all components that were removed.
Ensure all connections are tight and secure.
Reconnect the battery.
