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 repair.

2. Check and Change Engine Oil

Sub-steps:
1. Remove the oil fill cap and check the condition of the oil.
2. Drain the old oil using a wrench to remove the oil drain plug; allow oil to fully drain into a pan.
3. Replace the oil drain plug and torque it to the manufacturer’s specifications (usually around 25-30 ft-lbs).
4. Replace the oil filter with a new one, ensuring to lubricate the rubber gasket with new oil before installation.
5. Refill the engine with the appropriate type and amount of oil (typically 0W-20 or 5W-20, check the owner's manual for specifics).

3. Inspect and Replace Oil Pump

Sub-steps:
1. Remove the oil pan to access the oil pump (may require lowering the exhaust system).
2. Unbolt the oil pump and inspect for any damage or wear.
3. Replace the oil pump if necessary, ensuring it is properly aligned during installation.
4. Reinstall the oil pan with a new gasket, torquing bolts to specifications.

4. Clean Oil Passages

Sub-steps:
1. Use compressed air or a suitable cleaning solution to clear any debris from oil passages.
2. Ensure the oil pickup tube is clear and free of obstructions before reassembly.
