Cylinder Head: Installation

WARNING: This page is about a different car, the 2010 Mercury Milan and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
  1. Clean the cylinder head-to-cylinder block mating surface of both the cylinder head and the cylinder block in the following sequence below.
    1. Remove any large deposits of silicone or gasket material with a plastic scraper.
    2. Apply silicone gasket remover, following package directions, and allow to set for several minutes.
    3. Remove the silicone gasket remover with a plastic scraper. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
    4. Apply metal surface prep, following package directions, to remove any traces of oil or coolant, and to prepare the surfaces to bond with the new gasket. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.
    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 that make leak paths. Use a plastic scraping tool to remove all traces of the head gasket.
    NOTE: Observe all warnings or cautions and follow all application directions contained on the packaging of the silicone gasket remover and the metal surface prep.
    NOTE: If there is no residual gasket material present, metal surface prep can be used to clean and prepare the surfaces.
  2. Support the cylinder head on a bench with the head gasket side up. Check the cylinder head distortion and the cylinder block distortion. For additional information, refer to CYLINDER HEAD DISTORTION and CYLINDER BLOCK DISTORTION .
  3. Clean the cylinder head bolt holes in the cylinder block. Make sure all coolant, oil or other foreign material is removed.
  4. Apply silicone gasket and sealant to the locations shown.

  5. Install a new cylinder head gasket.
  6. Install the cylinder head and 10 new bolts. Tighten the bolts in the sequence shown below in the following 5 stages:
    • Stage 1: Tighten to 5 Nm (44 lb-in).
    • Stage 2: Tighten to 15 Nm (133 lb-in).
    • Stage 3: Tighten to 45 Nm (33 lb-ft).
    • Stage 4: Turn 90 degrees.
    • Stage 5: Turn an additional 90 degrees.
    NOTE: The cylinder head bolts are torque-to-yield and must not be reused. New cylinder head bolts must be installed.

  7. Connect the upper radiator hose, coolant bypass hose, EGR coolant hose, heater hose and coolant vent hose to the engine coolant outlet and the EGR valve.
  8. Connect the EGR valve electrical connector.
  9. Install the catalytic converter. For additional information, refer to INSTALLATION .
  10. Install the valve tappets in their original positions.
    NOTE: Lubricate the valve tappets with clean engine oil.

  11. Install the camshafts and bearing caps in their original location and orientation. Tighten the bearing caps in the sequence shown below in 3 stages:
    • Stage 1: Tighten the camshaft bearing cap bolts, one turn at a time, until finger-tight.
    • Stage 2: Tighten the bolts to 7 Nm (62 lb-in).
    • Stage 3: Tighten the bolts to 16 Nm (142 lb-in).
    NOTE: Install the camshafts with the alignment notches in the camshafts lined up so the camshaft alignment plate can be installed. Make sure the lobes on the No. 1 cylinder are in the same position as noted in the removal procedure. Failure to follow this procedure can cause severe damage to the valves and pistons.
    NOTE: Lubricate the camshaft journals and bearing caps with clean engine oil.
