CHANGING FUEL FILTER
Removal—F-250/350/450/550 and Excursion
1. Remove the engine appearance
cover.
2. Remove the fuel filter cap by
turning counterclockwise.
3. Remove and discard old fuel filter
element and fuel filter o-ring.
4. Carefully clean the mating
surfaces.
Removal — E-Series
1. Remove the engine appearance cover.
2. Disconnect the battery ground cable, then all electrical connectors,
vacuum tubes and fasteners as necessary for removal.
3. Release the four retaining clamps on the air cleaner assembly, then lift
the air cleaner cover and remove the air cleaner(s).
4. Loosen the clamp on the air inlet tube, then disconnect the air inlet
tube from the resonator.
5. Remove the three bolts on the turbocharger heat shield, then the
turbocharger heat shield.
6. Remove the bolt and resonator from the vehicle.

7. Remove the fuel filter cap by
turning counterclockwise.
8. Remove and discard old fuel filter
element and fuel filter o-ring.
9. Carefully clean the mating
surfaces.
Installation—F-250/350/450/550 and Excursion
The engine will not run properly if the fuel filter is not installed
in housing.
1. Apply a coating of clean Diesel fuel to the new fuel filter o-ring.
2. Install new fuel filter o-ring onto fuel filter element.
3. Install new fuel filter and o-ring into the fuel filter housing.
4. Tighten cap onto fuel filter housing slowly, allowing fuel to soak into
the fuel filter element. Tighten cap until it contacts the housing.
5. Install engine appearance cover.
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.
Installation—E-Series
The engine will not run properly if the fuel filter is not installed
in housing.

2. Open the hood. Place an
appropriate container under the
filter drain under the vehicle.
3. Locate the fuel filter drain valve. If necessary, remove the engine
appearance cover. Refer toEngine Compartmentin theService points
chapter.
4.On F-Series and Excursion
models,open fuel filter drain valve
by turning clockwise. Allow to drain
for approximately 25 seconds or
until clean fuel is observed. Close
filter drain valve by turning
counterclockwise until firmly seated.

•Do not use alcohol, methanol or brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).Alcohol
and other liquids can cause engine damage from overheating or
freezing.
•Do not add extra inhibitors or additives to the coolant.These
can be harmful and compromise the corrosion protection of the engine
coolant.
•Do not mix with recycled coolant unless from a Ford-approved
recycling process (seeUse of Recycled Engine Coolantsection).
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the“cold full”level. For all other vehicles, which have a coolant
degas system with a pressurized cap, or if it is necessary to remove the
coolant pressure relief cap on the radiator of a vehicle with an overflow
system, follow these steps to add engine coolant.
To reduce the risk of personal injury, make sure the engine is
cool before unscrewing the coolant pressure relief cap. The
cooling system is under pressure; steam and hot liquid can come out
forcefully when the cap is loosened slightly.
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (an semi-clear plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the“cold fill range”or the“cold full”level on the
reservoir. If you removed the radiator cap in an overflow system, fill the
radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. (Cap must be tightly
installed to prevent coolant loss.)
After any coolant has been added, check the coolant concentration see
Checking Engine Coolantsection). If the concentration is not 50/50
(protection to–34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
