Glow plug pre-heat indicator
With the key in the ON position,
the
light will illuminate if glow
plug heat is necessary as a starting
aid. Wait until the light goes off
before starting. The light should always illuminate briefly, when the
ignition key is in the ON position. If the light does not illuminate, there
may be a problem. Refer toCold weather startingin theDriving
section of this supplement. After the engine starts, the light should
remain off. The light should always illuminate at least momentarily when
the engine is cold and the ignition is turned to ON. If it does not
illuminate, the glow plug system should be checked and repaired
promptly to avoid difficulty in cold starting.

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 ignition is turned to START (as part
of the light function check) and when the HFCM 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 HFCM. Refer
toDraining the HFCM and changing the fuel filtersin the
Maintenance and specificationssection of this supplement 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 the water separator while the engine is running.
Fuel may ignite if the separator is drained while the engine is
running or the vehicle is moving.
Engine air filter
The engine air filter warning light
illuminates when the air filter
restriction gauge reaches the
CHANGE FILTER mark.
The condition should be verified by inspecting the underhood air filter
restriction gauge; the warning light is only a secondary indicator. Always
use the underhood air filter restriction gauge to determine when the air
filter element needs to be changed.
The vehicle may be driven with the engine air filter warning light
illuminated/or when the underhood air filter restriction gauge has moved
to the CHANGE FILTER mark for up to 400 km (250 miles) without
damaging the engine or related components. However, the air filter
element must be replaced at the earliest opportunity. Refer toAir filter
restriction gauge (if equipped)in this section of the supplement for
more information.

Air filter restriction gauge (if equipped)
The restriction gauge, located on
the upper housing of the air cleaner
assembly, monitors the condition of
the air filter element in two ways:
•First, the colored indictor inside
the gauge highlights the
percentage that the air filter
element is clogged with dust or
contaminants. Refer to
Maintenance and specifications
chapter.
•Second, the gauge contains an electrical switch which illuminates a
warning light on the instrument cluster when the air filter element is
100% clogged. Refer to theEngine air filterwarning light in this
section of the supplement.
Check the air filter restriction gauge whenever the hood is raised to
perform general engine maintenance at least every 12,000 km (7,500
miles). If the vehicle is operated in extremely dusty conditions, check
the gauge at least every 800 km (500 miles), or two weeks, whichever
comes first.

Water should be drained from the
module assembly whenever the
warning light comes on. The WATER
IN FUEL light will come on when
approximately 100 cc (0.2 pints) of water accumulates in the module.
Replace the fuel filters with Ford Part No. 3C3Z-9N184–CA. This part
number includes filters and seals for both the engine-mounted and
frame-mounted filters.
DRAINING THE HFCM AND CHANGING THE FUEL FILTERS
Your vehicle is equipped with two fuel filters; one mounted on top of the
engine and the other, the HFCM, mounted inside the frame rail under
the driver-side floorboard near the transmission. Both filters should be
replaced at the same time. The Motorcraft part number for the
replacement filters is FD-4604.
HFCM drain procedure
1. Stop the vehicle andshut offthe engine.
The vehicle must be stopped with the engine off when draining
the HFCM. Fuel may ignite if separator is drained while the
engine is running or vehicle is moving.
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.
Maintenance and specifications
26

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.
4. Protecting yourself from engine
heat, pull out the dipstick, wipe it
clean and reinsert fully.
5. Read oil level on both sides of dipstick and use highest level (reading)
for the actual engine oil level.
6. Maintain the oil level between ADD and OPERATING RANGE on the
dipstick by adding oil as required. The distance from ADD to
OPERATING RANGE on the dipstick represents 1.9L (2 quarts). Do not
overfill. If the oil level exceeds OPERATING RANGE, oil consumption
may result.
Engine oil specifications
To help achieve proper engine performance and durability, it is important
that only engine lubricating oils of the proper quality are used in your
Diesel engine and that the engine oil is changedno laterthan the
recommended interval. Diesel engines require specially formulated oil to
Maintenance and specifications
28

If you are operating your vehicle under any of these conditions, observe
the following service procedures:
•Change engine oil and filter every 8,000 km (5,000 miles).
•Use Motorcraft oil or an equivalent oil conforming to Ford
Specification WSS-M2C171–D or API categories CI-4, CI–4/SL or
DHD-1. If CI-4 oil is not available, CH-4 is acceptable.
For more information refer theGeneral owner’s informationsection of
this supplement.
REPLACING THE AIR FILTER ELEMENT
When replacing the air filter element, use the Motorcraft air filter
element listed. Refer to theMotorcraft part numberschart in this
section.
Note: Do not start your engine with the air cleaner removed and do not
remove it while the engine is running.
Failure to use the correct air filter element may result in severe
engine damage.
1. Remove the 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 auxiliary
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.
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 distilled 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
Rotunda Battery and Antifreeze Tester, 014–R1060). The level of coolant
should be maintained at the“cold full”of“cold fill range”level in the
coolant reservoir. If the level falls below, add coolant per the instructions
in theAdding engine coolantsection.
Maintenance and specifications
31

Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50–50 mixture of coolant and water provides the following:
•Freeze protection down to -36°C (-34°F).
•Boiling protection up to 129°C (265°F).
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.
When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the“cold fill level”or within the“cold
fill range”as listed on the engine coolant reservoir (depending upon
application).
•Refer to theGeneral owner’s informationfor service interval
schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein your owner’s guide.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool, until the appropriate fill level is obtained.
Maintenance and specifications
32

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 (a translucent 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, refer
toChecking 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.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 liter (1.0 quart) of engine coolant per
month, have your dealer check the engine cooling system. Your cooling
system may have a leak. Operating an engine with a low level of coolant
can result in engine overheating and possible engine damage.
Recycled engine coolant
Ford Motor Company does NOT recommend the use of recycled engine
coolant in vehicles originally equipped with Motorcraft Premium Gold
Engine Coolant since a Ford-approved recycling process is not yet
available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
