Wait to start:Indicates the air
intake heater is in operation and special starting procedures are
required. Refer to theDrivingchapter.
If equipped with an air intake heater, DO NOT use ether or any
other starting fluids. The use of starting fluids (ether) in an
engine equipped with an air intake heater could result in damage
and/or personal injury.
Water in fuel:During refueling, it
is possible for water-contaminated
diesel fuel to be pumped into your
tank. Your vehicle fuel system is
equipped with a fuel filter/water
separator to remove water from the fuel. The WATER IN FUEL light will
illuminate when the fuel filter/water separator has a significant quantity
of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the fuel
filter/water separator. Refer toFuel filter/water separatorin the
Maintenance and Specificationssection for the drain procedure.
Allowing water to stay in the system could result in extensive damage to,
or failure of, the fuel injection system.
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.
Traction control (if equipped):
Illuminates and flashes slowly if the
Off Road mode is selected and
flashes rapidly during a traction
control event.

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.
Use a Ford engine oil filter, part number FL-1995 or equivalent. This filter
protects your engine by filtering harmful, abrasive or sludge particles.
BATTERY
Your vehicle is equipped with two or three maintenance-free batteries
which are mounted in a covered tray and located on the left frame rail.
The covered battery tray, depending upon application, may also have one
or two steps attached.
•Covered battery tray shown.
Battery tray with steps similar.
The two rubber straps on top of
the cover must be pulled up and
moved to the side of the battery
in order to remove the lid.
• Battery tray with cover removed.
Maintenance-free batteries do not normally require adding additional
water.

If you drive in extremely hot climates:
•It is still necessary to maintain the coolant concentration
above 40%.
•NEVER decrease the coolant concentration below 40%.
•Engine coolant concentrations below 40% will decrease the
corrosion protection characteristics of the engine coolant and
may cause engine damage.
•Engine coolant concentrations below 40% will decrease the
freeze protection characteristics of the engine coolant and may
cause engine damage.
•If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle will provide
adequate protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
Fan clutches
Your vehicle’s cooling system is equipped with a viscous fan clutch.
•The fan clutch helps control cooling, increase performance, improve
fuel economy and reduce noise.
•The fan clutch is controlled by bimetallic spring sensors. Do not
tamper with these sensors as this may change their calibration or keep
the fan clutch from operating at all.
Stay clear of the fan/fan area while the engine is running or
possible personal injury may occur.
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
Scheduled Maintenance Guidechapter.

Draining the fuel filter/water separator – 6.0L Power Stroke engine
Water should be drained whenever
the warning light comes on or every
5,000 miles (8,000 km).
1. Stop the vehicle andshut offthe engine.
2. Locate the drain valve and place
a suitable container at the end of
the drain tube.
3. Turn the drain valve to the drain position and allow water to drain out.
Note:Drain until the water/fuel mixture becomes only fuel.
4. Turn the drain valve to the closed position.
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.

Draining the fuel filter/water separator - Caterpillar engine
1. With the engine off, open the
drain valve located at the bottom of
the fuel filter/water separator by
turning it counterclockwise.
2. Drain the filter until clear fuel is visible.
3. Turn the drain valve clockwise to close the valve. Do not overtighten
the drain valve as this could cause damage to the fuel filter/water
separator.
Fuel filter replacement - 6.0L Power Stroke engine
Removal
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
The engine will not run properly if the fuel filter is not installed
in housing.
1. Install new fuel filter 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.
Fuel filter replacement - Cummins B engine
Refer to your engine operator’s manual for service intervals and
procedures.
Fuel filter replacement - Caterpillar engine
The fuel filter/water separator is
located on the left side of the
engine. Replace the fuel filter/water
separator as recommended in the
Scheduled Maintenance Guide
chapter, or sooner if it becomes
plugged. Vehicles operated on fuel
with more than average impurities
may require replacement of the fuel
filter more frequently. The spin-on
filter has a water drain valve built
into the bottom of the filter canister.
Removal
1. Using an oil filter wrench, remove the filter.
2. Carefully clean the mating surfaces.
Installation
1. Fill the filter with clean, fresh diesel fuel.
2. Coat the filter seal with clean, fresh diesel fuel.
3. Hand-tighten the filter until it seats firmly against the mount, then
tighten (by hand) an additional
1 3to1 2turn.
4. Start the engine and check for fuel leaks.
