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 avoid electrical shorts.
2. Change Engine Oil and Filter

  1. Drain Old Oil

    • Place an oil drain pan under the oil pan.
    • Remove the oil drain plug using a socket wrench and allow the old oil to completely drain.
    • Torque specification for drain plug: 20-25 Nm (15-18 lb-ft).

  2. Replace Oil Filter

    • Locate the oil filter and remove it using an oil filter wrench.
    • Prepare the new oil filter by applying a thin layer of new oil to the rubber gasket.
    • Install the new oil filter by hand until snug, then tighten an additional 3/4 turn.

  3. Add New Oil

    • Replace the drain plug securely.
    • Using a funnel, add the recommended type and amount of new oil (typically 5W-30 or as specified in the owner’s manual).
    • Check the oil level with the dipstick and add oil as needed.
3. Inspect and Replace Oil Pump (if necessary)

  1. Remove Engine Cover

    • If applicable, remove any engine covers to access the oil pump.

  2. Remove Oil Pump

    • Disconnect the oil pump from the engine block, typically requiring removal of bolts.
    • Carefully separate the oil pump from the engine.

  3. Install New Oil Pump

    • Position the new oil pump in place and secure it with bolts, using the torque specification (refer to service manual for exact values).
    • Reconnect any hoses or electrical connectors that were removed.
