Solution

1. Preparation

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

2. Check and Top Off Engine Oil

Sub-steps:
1. Remove the dipstick, clean it with a rag, and reinsert it to check the oil level.
2. If low, add the correct type of oil as specified in the owner's manual.
3. Recheck the level after adding oil to ensure it is within the acceptable range.

3. Replace Oil Filter (if necessary)

Tools Required: Oil filter wrench, oil catch pan.
Sub-steps:
1. Place the oil catch pan under the oil filter.
2. Use the oil filter wrench to remove the old oil filter.
3. Apply a small amount of new oil to the rubber gasket of the new filter.
4. Install the new oil filter by hand, tightening it according to the manufacturer's specifications (typically 3/4 to 1 turn after gasket contact).

4. Replace Engine Oil (if necessary)

Tools Required: Socket set, oil catch pan, funnel.
Sub-steps:
1. Remove the oil drain plug using a socket set and allow the old oil to drain completely into the catch pan.
2. Replace the drain plug and tighten to the specified torque (usually around 20 lb-ft).
3. Pour in the recommended amount of new oil through the oil fill cap using a funnel.

5. Inspect and Replace Oil Pump (if necessary)

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Remove the oil pan to access the oil pump.
2. Inspect the oil pump for wear and damage. Replace if necessary.
3. Reassemble the oil pan and ensure proper torque specifications for all bolts.
