If you are looking for instructions on how to replace a 5.4 Liter SOHC Ford intake manifold, you have come to the right place here at JEGS. It is very important to be careful tightening the intake manifolds on these engines as they are made mostly of plastic and aluminum. Always refer to the appropriate shop manual for your specific year, make, and model vehicle to obtain specific service procedures. If you do not have a service manual or lack the skill to install this part, it is recommended that you seek the services of a qualified technician. Pay special attention to all cautions and warnings included in the shop manual. Read and follow all instructions carefully as failure to do so will result in severe damage to the intake manifold and to the engine.
- Carefully remove intake manifold per the service procedure outlined in shop manual.
- Clean all mounting surfaces.
- Reinstall intake manifold per shop manual.
- Tighten intake bolts as follows:
Stage One: 2 Nm (18 in-lbs)
Stage Two: 25 Nm (18 ft-lbs) - Install intake bolts in sequence shown below:
Installation Tech Tips
- This air intake manifold design does not require additional intake gaskets. The intake gaskets are already
installed into the manifold.
- Be sure to fully seat the injectors into intake manifold when installing the fuel rail. Failure to do so will result
in a vacuum leak and/or may prevent fuel rail from being properly attached.
- There are two sizes of thread-forming screws:
- The small thread-forming screws are used for mounting the ignition coils. Tighten to 2.7 to 3.3
Nm torque. DO NOT OVERTIGHTEN.
- The large thread-forming screws are to be tightened to 6 to 7 Nm. DO NOT OVERTIGHTEN.
- To install fuel rail fasteners, start each large fastener for three full rotations before tightening any fastener completely.
- Some large self tapping screws provided may not be used in your application – number of fasteners used will
vary based upon vehicle application.
- To attach PCV system connector at back of manifold, after installing O-ring, point PCV connector towards
passenger side of vehicle, lower connector into intake manifold and rotate connector clockwise until PCV
connector locks/clicks into place.
- Transferring NVH cover from original manifold is not required if original manifold was provided with one.
- Provided in the component kit will be an auxiliary coolant fitting that has sealant pre-applied to the threads.
Only for original applications that require an additional coolant connection, the installed plug must be removed.
-The provided auxiliary coolant fitting should be installed wrench-tight. Do not exceed 10 Nm. 1-3 threads
showing. DO NOT BOTTOM OUT FITTING
