3.0L Engine
Lower Manifold
Specific to:
Ford Fusion 2008-2009
Mercury Milan 2008-2009

CAUTION
Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited, resulting in possible personal injury.


CAUTION
Fuel in the fuel system remains under high pressure even when the engine is not running. Before repairing or disconnecting any of the fuel system components, the fuel system pressure must be relieved to prevent accidental spraying of fuel, causing personal injury or a fire hazard.

  1. Release the fuel system pressure, as outlined in the Fuel Section.
  2. Disconnect the battery ground cable.
  3. Remove the upper intake manifold.
  4. Disconnect the fuel supply tube quick connect coupling from the fuel rail.
  5. Detach the 2 wiring harness retainers from the LH valve cover stud bolts.
  6. Detach the 3 pin-type retainers from the fuel rail.
  7. Disconnect the 6 fuel injector electrical connectors.
  8. Remove the 8 lower intake manifold bolts and the lower intake manifold.
  9. Remove and discard the gaskets.
To install:

NOTE
Clean and inspect all sealing surfaces. Install new gaskets.

  1. Position the lower intake manifold and install the 8 bolts. Tighten in the sequence shown to 89 inch lbs. (10 Nm).

  2. Connect the 6 fuel injector electrical connectors.
  3. Attach the 3 pin-type retainers to the fuel rail.
  4. Attach the 2 wiring harness retainers to the LH valve cover stud bolts.
  5. Connect the fuel supply tube quick connect coupling at the fuel rail.
  6. Install the upper intake manifold.
  7. Connect the battery ground cable
Upper Manifold
Specific to:
Ford Fusion 2008-2009
Mercury Milan 2008-2009
  1. Remove the air cleaner outlet pipe.
  2. Disconnect the throttle body electrical connector.
  3. Remove the 4 bolts and position the throttle body aside. Discard the gasket.
