Disconnect the battery to avoid any electrical issues while working.

2. Check and Top Off Engine Oil

Tools Required: Oil filter wrench, funnel, rags
Sub-steps:
1. Remove the oil filler cap.
2. Using a clean dipstick, check the oil level.
3. If low, add oil that meets manufacturer specifications (check the owner's manual for the correct oil type).
4. Recheck the oil level after adding oil, ensuring it is within the acceptable range.
5. Reinstall the oil filler cap securely.

3. Inspect and Replace Oil Filter (if necessary)

Tools Required: Oil filter wrench, drain pan
Sub-steps:
1. Place a drain pan under the oil filter.
2. Use the oil filter wrench to remove the old oil filter.
3. Apply a small amount of fresh oil to the gasket of the new filter.
4. Install the new oil filter, tightening it according to the specifications provided (usually hand-tight + 3/4 turn).

4. Check and Replace Oil Pump (if defective)

Tools Required: Socket set, torque wrench, new oil pump, gaskets
Sub-steps:
1. Drain the engine oil completely using a drain pan.
2. Remove necessary components to access the oil pump (refer to service manual for specific steps).
3. Unbolt and remove the defective oil pump from its housing.
