  4. Remove the 2 power steering reservoir support bracket-to-cylinder head bolts and position the power steering reservoir and support bracket assembly aside.
  5. Remove the bolt and position the oil level indicator aside.
    NOTE
    When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector retaining clip area before separating from the tube.
  6. Disconnect the crankcase ventilation tube quick connect fitting.
    1. Push the connector toward the tube to release pressure.
    2. Push the release tab clockwise.
