Solution

1. Preparation

Tools Required: Oil pressure gauge, socket set, torque wrench, oil filter wrench, oil catch pan, replacement oil and oil filter.
Ensure the engine is cool and parked on a level surface. Disconnect the battery before proceeding.

2. Check and Replace Oil

Sub-steps:
1. Remove the oil filler cap and check the oil level with the dipstick.
2. If oil level is low, add the appropriate type and grade of oil as specified in the owner's manual.
3. If replacing oil, drain the old oil using an oil catch pan: remove the drain plug and allow the oil to drain completely.
4. Replace the drain plug and torque to the manufacturer's specifications.

3. Replace Oil Filter

Sub-steps:
1. Use an oil filter wrench to remove the old oil filter.
2. Apply a thin layer of new oil to the rubber gasket of the new filter.
3. Install the new oil filter, hand-tightening it to avoid leaks.

4. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove any components blocking access to the oil pump (e.g., timing cover, oil pan).
2. Disconnect the oil pump from the engine and remove it.
3. Install the new oil pump, ensuring the alignment is correct.
4. Torque the mounting bolts to the manufacturer's specifications.

5. Final Checks

Sub-steps:
1. Refill the engine with new oil if necessary, ensuring it meets the specifications.
2. Reconnect the battery and start the engine.
3. Monitor the oil pressure gauge for normal readings and check for leaks.
