Specific to:

Ford Fusion 2008-2009

Mercury Milan 2008-2009

WARNING

Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley bolt. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special service tools, otherwise severe engine damage can occur.

WARNING

During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.

To install:

WARNING

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.

WARNING

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.

1. Clean the cylinder head-to-cylinder block mating surface of both the cylinder head and the cylinder block.
2. Remove any large deposits of silicone or gasket material with a plastic scraper.
3. Apply silicone gasket remover, following package directions, and allow to set for several minutes.
4. 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.
5. 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.
6. Clean the cylinder head bolt holes in the cylinder block. Make sure all coolant, oil or other foreign material is removed.
7. Inspect the cylinder head for distortion.
8. Apply silicone gasket and sealant to the locations shown.
   
   
   

   

   Fig. Apply silicone gasket and sealant to the locations shown
9. Install a new head gasket.
   
   NOTE

   The cylinder head bolts are torque-to-yield and must not be reused. New cylinder head bolts must be installed.
   
   
   
   NOTE

   Lubricate the bolts with clean engine oil prior to installation.

    Fig. Remove the valve tappets from the cylinder head
31. Remove and discard the M6 bolt.
    
    WARNING

    Place clean rags over any exposed engine cavities. Also, carefully remove the towels so foreign materials do not drop into the engine.
    
    
    
    WARNING

    The cylinder head bolts must be discarded and new bolts must be installed. They are tighten-to-yield designed and cannot be reused.
    
    
    
    WARNING

    Aluminum surfaces are soft and can be easily scratched. Do NOT place the cylinder head gasket surface, unprotected, on a workbench surface.
    
    
    
    
    

    

    Fig. Remove and discard the M6 bolt
32. Remove and discard the 8 bolts from the cylinder head. Remove the cylinder head. Discard the cylinder head gasket.
    
    WARNING

    NEVER 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.
33. Clean the cylinder head-to-cylinder block mating surfaces of both the cylinder heads and the cylinder block.
34. Remove any large deposits of silicone or gasket material with a plastic scraper.
35. Apply silicone gasket remover, following package directions, and allow to set for several minutes.
36. 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.
37. Apply metal surface prep, following package directions, to remove any remaining 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.
38. Support the cylinder head on a bench with the head gasket side up.
    
    NOTE

    The straightedge used must be flat within 0.0051 mm (0.0002 in) per foot of tool length.
39. Inspect all areas of the deck face with a straightedge and feeler gauge. The cylinder head must not have depressions deeper than 0.0254 mm (0.001 in) across a 38.1 mm (1.5 in) square area, or scratches more than 0.0254 mm (0.001 in).
