Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface, and use wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Change Oil and Filter

Drain Oil: Remove the drain plug and allow old oil to drain completely into a suitable container.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber seal of the new filter with fresh oil.
- Install the new oil filter hand-tight.
Refill with New Oil:
- Replace the drain plug and tighten to manufacturer specifications.
- Refill with appropriate fresh engine oil (consult the owner’s manual for the correct viscosity).

3. Inspect and Replace Oil Pump (if needed)

Remove Oil Pan:
- Detach any components obstructing access to the oil pan.
- Remove the oil pan bolts and carefully lower the pan.
Replace Oil Pump:
- Disconnect the oil pump from the engine and remove it.
- Install the new oil pump, ensuring any gaskets or seals are properly placed.
- Reinstall the oil pan and tighten the bolts to specified torque values.

4. Reconnect Battery

Reconnect the battery terminals securely after completing the repairs.
