  2. Remove the oil drain plug and allow old oil to drain completely.
  3. Replace the oil filter using an oil filter wrench.
  4. Reinstall the drain plug and torque it to the manufacturer’s specifications (usually around 30 ft-lbs).
  5. Fill the engine with the recommended oil type (typically 5W-20 or 0W-20).

  6. Reconnect the electrical connector.

4. Inspect Timing Chain/Belt

• Sub-steps:
  1. Remove necessary components to access the timing chain/belt (this may include the front cover).
