Solution
1. Preparation
  • Tools Required: OBD-II scanner, mechanical oil pressure gauge, socket set, torque wrench, oil filter wrench, oil catch pan.
  • Disconnect the battery to ensure safety while working on electrical systems.
  • Allow the engine to cool before starting any work.
2. Change Engine Oil and Filter

  1. Drain Old Oil:

    • Place an oil catch pan under the oil pan.
    • Remove the oil drain plug using a socket set.
    • Allow the old oil to completely drain out.

  2. Replace Oil Filter:

    • Use an oil filter wrench to remove the old oil filter.
    • Lubricate the rubber seal of the new oil filter with fresh oil.
    • Install the new filter by hand and tighten it according to the manufacturer's specifications.

  3. Refill New Oil:

    • Replace the oil drain plug and torque it to the manufacturer’s specifications (usually around 25-30 Nm).
    • Pour in the new engine oil through the oil filler cap, using the recommended oil type and quantity (check the owner’s manual for specifics).
    • Start the engine and let it run for a few minutes, then check for leaks around the oil filter and drain plug.
3. Inspect and Replace Oil Pump (if necessary)

  1. Remove Oil Pan:

    • Disconnect any components obstructing the oil pan removal (e.g., exhaust, cross-member).
    • Unbolt the oil pan and remove it carefully.

  2. Inspect Oil Pump:

    • Check the oil pump for wear or damage. If defective, remove the oil pump by unbolting it from the engine block.
    • Replace with a new oil pump and torque bolts according to specifications.

  3. Reassemble:

    • Reinstall the oil pan with a new gasket, ensuring proper alignment.
    • Torque the oil pan bolts to the manufacturer’s specifications.
