  6. Install the oil pump screen and pickup tube and the 2 bolts.
    • Tighten to 10 Nm (89 lb-in).
  7. Clean all mating surfaces with metal surface prep.
    NOTE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges, which make leak paths. Use a plastic scraping tool to remove traces to sealant.
  8. Apply a 2.5 mm (0.09 in) bead of sealant gasket and sealant to the oil pan.
    NOTE: If the oil pan is not secured within 4 minutes of sealant application, the sealant must be removed and the sealing area cleaned with metal surface prep. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.
