2. Locate the HFCM and place an
appropriate container under the
drain plug (see illustration).
3. Remove the drain plug, using a 6mm hex drive, by turning it
counterclockwise. Allow the HFCM to drain for approximately 25 seconds
or until clean fuel is observed. Install the drain plug by turning it
clockwise until it is firmly seated.
4. Verify that the drain plug is closed and sealed, 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 - HFCM filter
1. Remove the fuel filter cap by
turning counterclockwise.
2. Remove and discard the old fuel
filter element.
3. Carefully clean the mating
surfaces.

Removal - Engine-mounted fuel filter
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 (from Ford Part No.
3C3Z-9N184–CA) into the fuel filter housing.
2. Tighten cap onto fuel filter housing slowly, allowing fuel to soak into
the fuel filter element. Tighten cap until it contacts the housing.
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.
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 assure that the oil
contained in the upper parts of the engine has returned to the oil pan.

* Heavy duty trailer towing with ambient temperatures above 10°C
(50°F) requires 15W-40 engine oil.
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.
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. The lower section will state energy
conserving if the oil has proven fuel saving capabilities.
Changing engine oil and filter
Change your oil and filter according to the scheduled maintenance guide.
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 section
Engine lubrication for severe service operationfor all severe duty
restrictions.
Use Ford Engine Oil Filter Part No. 3C3Z-6731–AA (FL–2016) or
equivalent. These filters protect your engine by filtering harmful,
abrasive or sludge particles. The FL–2016 filters particles significantly
smaller than most available“will-fit”filters.
