Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repairs.

2. Check and Top Off Engine Oil

Tools Required: Oil filter wrench, funnel, clean rag, appropriate engine oil.
Sub-steps:
1. Remove the oil filler cap.
2. Use the dipstick to check the oil level; add oil if low.
3. Replace the oil filler cap securely.

3. Replace Oil Filter

Tools Required: Oil filter wrench, oil catch pan.
Sub-steps:
1. Place the oil catch pan under the oil filter.
2. Remove the old oil filter using the oil filter wrench.
3. Apply a thin layer of new oil to the gasket of the new oil filter.
4. Install the new oil filter by hand until snug, then tighten slightly with the wrench.

4. Inspect and Replace Oil Pump (if necessary)

Tools Required: Socket set, torque wrench, oil pump removal tool.
Sub-steps:
1. Drain the engine oil completely into a catch pan.
2. Remove the oil pan by loosening the bolts (torque specifications in the service manual).
3. Detach the oil pump from the engine block.
4. Install the new oil pump, ensuring it is aligned correctly.
5. Reattach the oil pan and torque to the manufacturer's specifications.

5. Verify Oil Pressure

Tools Required: Mechanical oil pressure gauge.
Sub-steps:
1. Remove the oil pressure sending unit using a socket.
2. Install the mechanical gauge in place of the sending unit.
3. Start the engine and monitor the pressure reading; it should be within the specified range.
4. Once confirmed, reinstall the oil pressure sending unit.
