Solution

1. Preparation

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

2. Change Engine Oil and Filter

Tools Required: Oil filter wrench, socket set, oil catch pan, funnel
Sub-steps:
1. Place the oil catch pan under the oil pan.
2. Remove the oil drain plug using a socket set and allow the old oil to completely drain.
3. Replace the oil drain plug and torque it to the manufacturer’s specification (typically 25 ft-lbs).
4. Remove the old oil filter using an oil filter wrench and install a new one, lubricating the rubber gasket with new oil.
5. Fill the engine with new oil of the correct type (typically 0W-20 or 5W-20, check owner's manual for specifications).

3. Inspect and Replace Oil Pump (if necessary)

Tools Required: Socket set, torque wrench, gasket scraper
Sub-steps:
1. Remove the engine cover to access the oil pump.
2. Disconnect any components obstructing the oil pump (like timing chain/belt, if necessary).
3. Unbolt the oil pump from the engine block.
4. Clean the mounting surface on the engine block using a gasket scraper.
5. Install the new oil pump and torque to manufacturer specifications.
6. Reassemble any components previously removed.

4. Check for Oil Leaks

Tools Required: None specifically, but a visual inspection is necessary.
Sub-steps:
1. Start the engine and let it run for a few minutes.
2. Inspect around the oil filter, oil pan, and oil pump for any signs of leaking oil.
3. Address any leaks by tightening fasteners or replacing seals/gaskets as needed.
