Ford 1W7Z-9424-AA Inlet Manifold Assembly

During installation, ensure the gasket is in place and position new gasket(s) onto the lower intake mounting face. Secure the air intake plenum and throttle body assembly with the six upper intake manifold retaining bolts, tightening them to the specified torque.

Relieve the fuel system pressure and disconnect the cable from the negative battery terminal.

After disconnecting the electrical and vacuum connectors, the distributor is removed, followed by relieving the fuel system pressure and disconnecting the fuel supply and return lines. If equipped, the carburetor is also removed.

After completing the installation, you should reassemble the components and check for oil and coolant leaks at the intake manifold joints after starting the engine.

Relieve fuel pressure, remove the air intake plenum assembly on 5.0L engines or the air intake assembly on 4.6L engines, and remove the fuel rail assembly. Detach the electrical connectors from the injectors, remove the injectors, inspect and replace injector O-rings and other components as needed. Lubricate new O-rings with oil before installation and twist to install the injectors. The remainder of the installation is the reverse of removal.
