Water in fuel (if equipped)
During refueling it is possible for
water-contaminated diesel fuel to be
pumped into your fuel tank. Your
vehicle fuel system is equipped with
a fuel filter/water separator to
remove water from the fuel. The indicator light illuminates when the fuel
filter/water separator has a significant quantity of water, or when the
ignition key is switched to the START position. If the light illuminates
when the engine is running, stop the vehicle as soon as safely possible,
shut off the engine and drain the filter bowl. Allowing water to stay in
the system could result in extensive damage to, or failure of, the fuel
injection system.
To drain the fuel filter/water separator (refer toMaintenance and
Specificationschapter for procedure). Rotate the valve at the bottom of
the filter assembly allowing water to drain from the system. Close the
valve upon completion.
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.
Air clean warning (if equipped)
Illuminates when the air system is
restricted (dirty, clogged).
Turn signal
Illuminates when the left or right
turn signal or the hazard lights are
turned on. If one or both of the
indicators stay on continuously or flash faster, check for a burned-out
turn signal bulb. Refer toExterior bulbsin theLightschapter.
High beams
Illuminates when the high beam
headlamps are turned on.

Engine oil and filter recommendations—7.3L Power Stroke engine
To help achieve proper engine performance and durability, it is important
that you:
•Use only engine lubricating oils and oil filters of the proper quality.
•Change the engine oil and filterno laterthan the recommended
service interval. Refer to the general maintenance information section
for the appropriate intervals for changing the engine oil and filter.
•Change your engine oil and filter more frequently if your vehicle
operation includes extended periods of idling or low-speed operation,
driving for a long time in cold temperatures or short driving distances.
Diesel engines require specially formulated oil to resist contamination.
Proper quality oils also provide maximum efficiency of the crankcase
ventilation system which reduces air pollution.
For normal or severe service, use Motorcraft oil or an equivalent oil
conforming to Ford Specification WSS-M2C171–C or API Service
categories CH-4, CH-4/SJ or CH-4/SL. If CH-4 oil is not available, CG-4 is
acceptable.
Diesel engine oils with improved fuel economy properties (energy
conserving) are currently available. If you use an energy conserving oil,
be sure it meets Ford specification WSS-M2C171–C or API service
category designation CH-4/SL and is of the proper viscosity grade for the
temperature range in which you expect to operate your vehicle. Some
energy conserving oils do not meet the requirements necessary for your
diesel engine.

Running out of fuel
Avoid running out of fuel as this will allow air to enter the fuel system,
which will make restarting the vehicle difficult.
If you have run out of fuel:
•If your vehicle is equipped with dual fuel tanks,add at least
15–19 liters (4–5 gallons) of fuel to each tank before attempting to
restart the engine.
•If your vehicle is equipped with the Caterpillar 3126 B engine,
the fuel system must be primed before attempting to restart the
engine. Refer to the engine operator’s manual for instructions on
priming the engine.
•Use caution not to overheat and damage the starterby cranking
the engine for an excessive period of time. You may need to crank the
engine for a longer time than normal. If the engine fails to start in 30
seconds, turn the ignition to the OFF position and wait for two
minutes before cranking the engine again.
•Any remaining trapped air will self-purge from the fuel system once
the engine starts running.
•The engine may run rough and produce white smoke while air is in
the fuel system. This is normal and should stop after a short period of
time.
Fuel filter/water separator
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.
The fuel filter/water separator removes any contaminated particles
and/or water from the fuel before the fuel enters the engine.
The fuel filter/water separator should be drained as recommended in the
general maintenance information section.

1. Apply a coating of clean diesel fuel to the new bevel gasket and install
it onto the fuel filter housing.
2. Install the new fuel filter element onto the cap. Place the new fuel
filter element and cap into the fuel filter housing. Allow fuel to soak into
the fuel filter element.
3. Tighten cap onto the fuel filter housing until cap contacts the housing.
4. Start the engine and check for fuel leaks.
After changing the fuel filter, the engine will purge the trapped air as it
runs. Engine may run roughly and smoke until the air is completely
eliminated.
Fuel filter replacement—Cummins B engine
Refer to your engine operator’s manual for service intervals and
procedures.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1 600 km (1 000
miles) of driving (engine break-in period). You will get a more accurate
measurement after 3 000 km–5 000 km (2 000 miles-3 000 miles).
The advertised fuel capacity of the fuel tank(s) on your vehicle is equal
to the rated refill capacity of the fuel tank(s) as listed inFuel Tank
Capacitiesin this chapter. The advertised capacity is the amount of the
Indicated Capacity and the Empty Reserve combined. Indicated Capacity
is the difference in the amount of fuel in a full tank and a tank when the
fuel gauge indicates empty. Empty Reserve is the small amount of usable
fuel remaining in the fuel tank after the fuel gauge indicates empty.
The amount of Empty Reserve varies and should not be relied
upon to increase driving range. When refueling your vehicle after
the fuel gauge indicates empty, you might not be able to refuel
the full amount of the advertised capacity of the fuel tank due to
the empty reserve still present in the tank.
Your vehicle may be equipped with dual fuel tanks. If so, you will have a
selector control. For information on the Dual Fuel Tank Selector Control
refer to theDriving Tipssection in the7.3 Liter Power Stroke Direct
Injection Turbo Diesel Owner’s Guide Supplement.

•If your vehicle is equipped
with the 7.3L Power Stroke
engine,it will be necessary to
remove the air filter element from
the filter housing by moving the
exposed end of the filter element
down and to the rear of the
vehicle, then lifting the other end
of the filter element up and out
of the engine compartment.
•If your vehicle is equipped with the Cummins B engine,a
secondary air filter is located the bottom of the air filter housing to
keep dirt and debris from falling into the engine when the air filter
element is being removed. This secondary filter needs to be replaced
only after the primary air filter element has been replaced several
times. If necessary replace the secondary air filter.
5. Reach inside the air filter housing and clean the outlet tube where it
extends into the housing. Be sure not to damage the tube because the
air filter element seals around this surface.
6. Check to be sure that the drain hole in the air filter housing is open
and clear of any dirt and debris.
7. Check to be sure the new air filter element is not damaged, then
install it. Make sure there is a tight seal (apply pressure at the outer rim
of the element, not the flexible center).
8. Align the air filter cover latches with the holes in the air filter housing
and install the cover.
9. Push in on the cover latches, then turn the latches clockwise 90
