2008 FORD SUPER DUTY maintenance

DRAINING THE FCM/HFCM AND CHANGING THE ENGINE AND
VEHICLE FUEL FILTERS
Your vehicle is equipped with two fuel filters; one is mounted on top of
the engine.On F-Super Duty,the second filter, inside the HFCM, is
mounted inside the frame rail under the driver-side floorboard near the
transmission.On E-Series,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. Regular fuel
filter changes are an important part of engine maintenance; failing to
keep with the scheduled maintenance could lead to engine performance
issues and/or fuel injection system damage. Refer to theScheduled
Maintenance Guidechapter of this supplement for more information.
Refer toMotorcraft Part Numberslater in this chapter for the fuel filter
replacement part number. This part number includes filters and seals for
both the engine-mounted and frame-mounted filters.
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).

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.
Removal - FCM filter (E-Series)
1. Remove the fuel filter cap by
turning counterclockwise.

1. Remove the fuel filter cap by turning counterclockwise.
2. Remove and discard the old fuel filter element.
3. Carefully clean the mating surfaces.
Installation - both
The engine will not run properly if the fuel filter is not installed
in housing.
1. Install the new fuel filter and cap seal into the fuel filter housing.
Refer toMotorcraft Part Numberslater in this chapter for the fuel filter
part number.
2. Tighten cap onto fuel filter housing slowly, allowing fuel to soak into
the fuel filter element. Tighten cap until it contacts the housing.

On E-Series vehicles:After replacing the fuel filter, the engine will
purge the trapped air as it runs. The engine may run roughly and smoke
until the air is completely eliminated.
On F-Super Duty vehicles:Turn the ignition key to ON for 30 seconds,
then turn it to OFF. Do this a total of six times in a row to purge any
trapped air from the fuel system.
Using a fuel which has more than average impurities may require
the fuel filter to be replaced more frequently than the service
interval specifies.
ENGINE OIL
Checking the engine oil level
Because it is normal to add some oil between oil changes, check your
engine oil level each time you stop for fuel. To check the engine oil level
consistently and accurately, the following procedure is recommended:
1. Have engine at normal operating temperature (at least into the
NORMAL range on the engine coolant temperature gauge).
2. Park the vehicle on a level surface, then turn off the engine and open
the hood.
3. Allow at least20 minutesafter engine shutdown to ensure that the
oil contained in the upper parts of the engine has returned to the oil
pan.
4. Protecting yourself from engine heat, pull out the dipstick, wipe it
clean and reinsert fully.
5. Read oil level on both sides of dipstick and use highest level (reading)
for the actual engine oil level.
6. Maintain the oil level between MIN and MAX or the ADD and
OPERATING RANGE on the dipstick by adding oil as required. The
distance from MIN to MAX or ADD to OPERATING RANGE on the
dipstick represents 2.0 quarts (1.9L). Do not overfill. If the oil level
exceeds MAX or OPERATING RANGE, oil consumption may result.
Engine oil specifications
To help achieve acceptable engine performance and durability, it is
important that only engine oils of good quality are used in your diesel
engine and it is changed at the recommended interval. For normal or
severe service, use Motorcraft oil or an equivalent oil conforming to Ford
specification WSS-M2C171–E or API service categories CJ-4 or CJ-4/SM.

It is important to use these oils because they are compatible with the
emission control equipment of your vehicle to meet the more stringent
emission standards.
The use of correct oil viscosities for diesel engines is important for
satisfactory operation. Determine which oil viscosity best suits the
temperature range you expect to encounter for the next service interval
from the following SAE viscosity grade charts. The charts are separated
by vehicle/engine type due to different engine oil viscosity requirements
at different temperatures.
E-Series vehicles (6.0L engine):

F-Super Duty vehicles (6.4L engine):
•An engine block heater must be used at temperatures below
–10°F (–23°C).
•Use the same engine oil and filter change intervals when using
synthetic engine oil.
•Heavier 15W–40 and 5W–40 engine oils are recommended for
temperature over 50°F (10°C) and must be used for heavy duty
driving and trailer towing.
A symbol has been developed by the
American Petroleum Institute (API)
to help you select the proper engine
oil. It will be included on the oil
container you purchase. The top
section of the symbol shows the oil
performance by the API designation.
This should match the owner guide recommendation. The center section
will show the SAE viscosity grade
Changing engine oil and filter
Change your oil and filter according to thescheduled maintenance
informationin this supplement. Change more frequently if your vehicle

operation includes extended periods of idling or low-speed operation,
driving for a long time in cold temperatures or driving short distances.
See the following sectionEngine lubrication for severe service
operationfor all severe duty restrictions.
Refer toMotorcraft Part Numberslater in this chapter for the engine oil
filter part number. This filter protects your engine by filtering harmful,
abrasive or sludge particles and particles significantly smaller than most
available “will-fit” filters.
To replace the filter,
1. Unscrew the oil filter cap and wait a few seconds for the oil to drain
through the built-in drain valve.Note:The filter should be changed
before reinstalling the oil pan drain plug.
2. Reinstall and tighten the oil filter cap.
Do not handle a hot oil filter with bare hands.
Continuous contact with USED motor oil has caused cancer in
laboratory mice. Protect your skin by washing with soap and
water.
Engine lubrication for severe service operation
The following severe service operating conditions require unique engine
maintenance procedures:
•frequent or extended idling (over 10 minutes per hour of normal
driving).
•if vehicle is operated in sustained ambient temperatures below -10°F
(-23°C) or above 100°F (38°C)
•frequent low speed operation, consistent heavy traffic less than 25
mph (40 km/h)
•operating in severe dust conditions.
•towing a trailer over 1,000 miles (1,600 km)
•sustained, high speed driving at Gross Vehicle Weight Rating
(maximum loaded weight for vehicle operation)
If you are operating your vehicle under any of these conditions, change
engine oil and filter every 5,000 miles (8,000 km).
