WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty and 2013 Ford F-450 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
  1. 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 all traces of old sealant. Failure to follow this procedure may cause future oil leakage.

    Inspect the oil pan. Clean the mating surface for the oil pan with silicone gasket remover and metal surface prep. Follow the directions on the packaging.

  2. NOTE: Make sure to install a new O-ring seal. A missing or damaged O-ring seal can cause foam in the lubrication system and low oil pressure. Failure to follow this instruction may result in engine damage.
    NOTE: Clean and inspect the mating surfaces and install a new O-ring seal. Lubricate the O-ring seal with clean engine oil.

    Install a new O-ring seal onto the oil pump screen and pickup tube.

  3. Position the oil pump screen and pickup tube in the oil pan and position the oil pan and new gasket into the vehicle.
  4. NOTE: Make sure to install a new O-ring seal. A missing or damaged O-ring seal can cause foam in the lubrication system and low oil pressure. Failure to follow this instruction may result in engine damage.
    NOTE: Clean and inspect the mating surfaces and install a new O-ring seal. Lubricate the O-ring seal with clean engine oil prior to installation.

    Position the oil pump screen and pickup tube and install the bolts.

    • Tighten the oil pump screen and pickup tube-to-oil pump bolts to 10 Nm (89 lb-in).
    • Tighten the oil pump screen and pickup tube-to-spacer bolt to 25 Nm (18 lb-ft).
  5. NOTE: If the oil pan is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with silicone gasket remover and metal surface prep. Follow the directions on the packaging. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure may cause future oil leakage.

    Apply silicone gasket and sealant at the crankshaft rear seal retainer plate-to-cylinder block sealing surface.

  6. NOTE: If the oil pan is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with silicone gasket remover and metal surface prep. Follow the directions on the packaging. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure may cause future oil leakage.

    Apply silicone gasket and sealant at the engine front cover-to-cylinder block sealing surface.
