fuel filter FORD SUPER DUTY 2003 1.G 7.3L Diesel Engine User Guide

Failure to use the correct air filter element may result in severe
engine damage.
1. Remove air filter element from the housing, taking care to prevent dirt
from falling into the engine air intake.
2. Clean the air filter housing and cover to ensure good sealing.
3. Install a new air filter element. Be careful not to crimp the filter edges
between the air filter housing and cover. This could cause damage to the
air filter element and possible severe damage to the engine.
When servicing the air filter, always be sure that the rubber
water drain hose is not kinked or obstructed. Failure to do so
may result in severe engine damage when driving through deep
water and/or encountering unusually heavy precipitation
conditions.
FUEL FILTER/WATER SEPARATOR
The engine is equipped with a combination fuel filter/water separator
located in the“V”of the engine.
•E-Series
•F-250/350/450/550, Excursion
Water should be drained from the
filter bowl whenever the warning
light comes on or every 8 000 km
(5 000 miles). The WATER IN FUEL light will come on when
approximately 100 cc (0.2 pints) of water accumulates in the separator.
Replace the fuel filter with Motorcraft Part No. FD-4596 (Ford Part No.
F81Z-9N184–AA).
Fuel filter/water separator drain procedure
1. Stop the vehicle andshut offthe engine.
The vehicle must be stopped with the engine off when draining
the fuel filter/water separator. Fuel may ignite if separator is
drained while the engine is running or vehicle is moving.

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.

4.On E-Series models,open fuel filter drain valve by pulling on the
release handle. Allow to drain for approximately 25 seconds or until
clean fuel is observed. Close filter drain valve by resetting handle to
original position.
5. Verify that the fuel filter drain valve is closed. If removed, install the
engine appearance cover.
6. Close the hood and remove the container from under the vehicle.
7. Restart the engine and check WATER IN FUEL indicator light. The
light should not glow. If it continues to glow, have fuel system checked
and repaired.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant and water, which
equates to a freeze point of -36°C (-34°F). Coolant concentration
testing is possible with a hydrometer or antifreeze tester (such as the

The complexity of the Diesel engine makes it so the owner is
discouraged from attempting to perform maintenance other than the
services described in this supplement.
If you experience difficult starting, rough idling, excessive exhaust
smoke, a decrease in engine performance or excess fuel consumption,
perform the following checks:
•a plugged air inlet system or engine air filter element.
•water in the fuel filter/water separator.
•a clogged fuel filter.
•contaminated fuel.
•air in the fuel system, due to loose connections.
•an open or pinched sensor hose.
•low engine oil level.
•wrong fuel for climactic conditions.
If these checks do not help you correct the engine performance problem
you are experiencing, consult an authorized dealer.
FUELING
Do not use starting fluid such as ether or gasoline in the Diesel
air intake system. Such fluids can cause immediate explosive
damage to the engine and possible personal injury.
If you fuel your vehicle at a truck stop, you may notice that the fuel
nozzle may shut off every 5–10 seconds. This is due to the flow rates
being designed for larger heavy duty trucks. You may have to fuel at a
slower rate (don’t depress the nozzle trigger fully).
Do not run your Diesel vehicle out of fuel as this will allow air to enter
the fuel system which will make restarting difficult. Longer engine
cranking time may be required once air is in the fuel system. If air enters
the fuel system (either through running the fuel tank(s) empty or during
a fuel filter change), the engine will self-purge the trapped air once it
starts running. The engine may run roughly and produce white smoke
while air is in the fuel system; this is normal and should stop after a
short time.
