Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery negative terminal for safety.

2. Change Engine Oil and Filter

Tools Required: Socket set, oil filter wrench, oil catch pan, funnel
Sub-steps:
1. Remove the oil drain plug with a socket wrench and allow old oil to drain completely into the catch pan.
2. Replace the oil drain plug and torque to manufacturer specifications (typically around 20 ft-lbs).
3. Use the oil filter wrench to remove the old oil filter.
4. Apply a small amount of new oil to the rubber gasket of the new filter.
5. Install the new oil filter and tighten it by hand until snug.
6. Refill the engine with the recommended oil type (typically 0W-20 or 5W-20) using a funnel.
7. Start the engine and let it run for a few minutes, checking for leaks around the filter and drain plug.

3. Inspect Oil Pump and Relief Valve

Tools Required: Torque wrench, socket set
Sub-steps:
1. Remove the oil pan by unbolting it from the engine block; ensure to replace the gasket with a new one.
2. Inspect the oil pump: ensure it is properly mounted and check for any visible damage.
3. Remove the oil pump if necessary, and check the relief valve for proper operation; clean or replace if blocked or damaged.
4. Reinstall the oil pump and oil pan; torque bolts to manufacturer specifications.
