2005 FORD SUPER DUTY Diesel Supplement Manual

ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean.
•Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
•Cover the highlighted areas to prevent water damage when cleaning
the engine.

SCHEDULED MAINTENANCE
The scheduled maintenance services in theGeneral Owner’s
Informationsection of this supplement are required because they are
considered essential to the life and performance of your vehicle.
Use only recommended fuel, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraft parts are designed and
built for best performance in your vehicle.
FUEL REQUIREMENTS
Choosing the right fuel
The engine is designed to use low sulfur number 1–Dor2–D Diesel fuel
only. At temperatures below -7°C (20°F), number 1–D or winter blend
number 2–D fuel is recommended. (SeeCold weather operationin the
Drivingchapter of this supplement.) Diesel fuel containing no more
than 5% of biodiesel may be used. Biodiesel fuel is a product derived
from renewable fuel sources such as vegatable oil, animal fat and cooking
oil.
Do not use home heating oil or any diesel fuel not intended for
highway use. Red dye is used to identify fuels intended for
agricultural and non-highway use. Damage to the fuel injection
system, engine and exhaust catalyst can occur if an improper fuel
is used. Do not add gasoline, gasohol or alcohol to diesel fuel.
This practice creates a serious fire hazard and engine
performance problems.
Fuel quality
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel that meets the ASTM D
Maintenance and Specifications
29

975 industry specification. Aftermarket additives can damage the injector
system or engine. Repairs to correct the effects of using an aftermarket
product in your fuel may not be covered by your warranty.
Do not blend used engine oil with diesel fuel under any
circumstances.Blending used oil with the fuel will significantly increase
your vehicle’s exhaust emissions and reduce engine life due to increased
internal wear.
Many of the world’s automakers approved the World-wide Fuel Charter
that recommends diesel fuel specifications to provide improved
performance and emission control system protection for your vehicle.
Diesel fuel that meets the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about fuel that meets the World-wide
Fuel Charter.
Fueling tips
If the engine fails to start in 30 seconds, turn the key to the OFF
position and wait 30 seconds before trying again.
Truck stops have pumps and nozzles designed for larger, heavy-duty
trucks. When refueling at truck stops: if the nozzle shuts off repeatedly
when refueling, wait 5–10 seconds; then use a slower rate of flow (don’t
depress the nozzle trigger as far).
If air is allowed to enter the fuel system (during fuel filter change or if
you run out of fuel) the engine will purge the trapped air as it runs. The
engine may run rough and produce white smoke while air is in the
system. This is normal and should correct itself in a short time.
An engine that suddenly becomes noisy or operates poorly after a fuel fill
could be using substandard fuel (i.e., high water content, low cetane
rating or gasoline in the fuel). Diesel fuel should be purchased from a
reputable station which sells a large amount of diesel fuel.
Care should be taken whenever diesel fuel is stored. Use only clean,
approved containers which will prevent the entry of dirt or water.
Diesel fuel must not be stored in a galvanized container. The fuel will
dissolve the zinc in a galvanized container. The zinc will then remain in
solution until it is run through the engine where it will be deposited in
the fuel injectors causing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
This truck is equipped with a fuel fill pipe which is able to accept fuel up
to 20 gallons per minute from an 1 1/8 inch fuel dispensing nozzle.
Pumping fuel at greater flow rates may result in premature nozzle
shut-off or spitback.

FUEL CONDITIONER MODULE (FCM - E-SERIES)/HORIZONTAL
FUEL CONDITIONING MODULE (HFCM - F-SUPER
DUTY/EXCURSION) - FUEL FILTER/WATER SEPARATOR
HFCM - F-Super Duty/Excursion
The vehicle is equipped with a Horizontal Fuel Conditioning Module
(HFCM) located on the frame-rail under the driver-side floorboard near
the transmission.
Water should be drained from the
module assembly whenever the
warning light comes on. The WATER
IN FUEL light will come on when
approximately 100 cc (0.2 pints) of water accumulates in the module.
Replace the fuel filters with Ford Part No. FD–4604. This part number
includes filters and seals for both the engine-mounted and
frame-mounted filters.
FCM - E-Series
The vehicle is equipped with a Fuel Conditioning Module (FCM) located
on the driver-side of the vehicle next to the transmission case.
Water should be drained from the
module assembly whenever the
warning light comes on. The WATER
IN FUEL light will come on when
approximately 100 cc (0.2 pints) of water accumulates in the module.
Replace the fuel filters with Ford Part No. FD–4604. This part number
includes filters and seals for both the engine-mounted filter and the FCM
filter.
DRAINING THE FCM/HFCM AND CHANGING THE FUEL FILTERS
Your vehicle is equipped with two fuel filters; one is mounted on top of
the engine.On F-Super Duty and Excursion vehicles,the second
filter, inside the HFCM, is mounted inside the frame rail under the
driver-side floorboard near the transmission.On E-Series vehicles,the
second filter, inside the FCM, is mounted on the driver-side of the
vehicle next to the transmission case.On all vehicles,both filters
should be replaced at the same time. The Motorcraft part number for the
replacement filters is FD-4604.

FCM/HFCM drain procedure
1. Stop the vehicle andshut offthe engine.
The vehicle must be stopped with the engine off when draining
the HFCM/FCM. Fuel may ignite if the separator is drained while
the engine is running or vehicle is moving.
2. Locate the HFCM and place an appropriate container under the drain
port (see illustration).
•F-Super Duty/Excursion
•E-Series
3. Rotate drain lever to the outward position. Allow the HFCM/FCM to
drain for approximately 25 seconds or until clean fuel is observed. Rotate
the lever towards the housing until it is firmly seated.
4. Verify that the drain valve is closed and latched, then remove the
container from under the vehicle.
5. Restart the engine and check WATER IN FUEL indicator light; it
should not be illuminated. If it continues to illuminate, have the fuel
system checked and repaired.
