Operation in standing water
Ingestion of water into the diesel engine can result in immediate and
severe damage to the engine. If driving through water, slow down to
avoid splashing water into the intake. If the engine stalls, and ingestion
of water into the engine is suspected, do not try to restart the engine.
Consult your dealer for service immediately. Follow the cylinder
compression test procedure outlined in the Workshop Manual, then
check the engine oil for contamination.

JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Do not push start your vehicle. You could damage the catalytic
converter.
Batteries contain sulfuric acid which burns skin, eyes, and
clothing.
Preparing your vehicle
Also see the label on the battery.
1. Use only a 12±volt supply to start your vehicle. If you connect your
battery to a 24±volt power supply you can damage your starter, ignition
system and other electrical components. Do not attach the jumper cables
to the glow plug relay as this could severely damage the glow plugs,
injector driver module and PCM.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle's electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure theydo nottouch. Set the parking brake on both vehicles
and stay clear of the engine cooling fan and other moving parts.

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.
ENGINE OIL
Checking 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.
4. 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.
5. Protecting yourself from engine
heat, pull out the dipstick, wipe it
clean and reinsert fully.
6. Read oil level on both sides of dipstick and use highest level (reading)
for the actual engine oil level.
7. 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.

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.
Changing engine oil and filter
Change your oil and filter according to the ªService Guideº. Change more
frequently if your vehicle operation includes extended periods of idling
or low-speed operation, driving for a long time in cold temperatures or
driving short distances. See the following section ªEngine Lubrication for
Severe Service Operationº for all severe duty restrictions.
Use Ford Engine Oil Filter Part No. F4TZ-6731±A (FL±1995) or
equivalent. These filters protect your engine by filtering harmful,
abrasive or sludge particles. The FL±1995 filters particles significantly
smaller than most available ªwill fitº filters.
To replace, use an oil filter wrench to unscrew the filter from the oil
cooler fitting. Turn it horizontally to let excess oil drain off, and remove.
Do not handle a hot oil filter with bare hands.
Clean the filter mounting area on the oil cooler, lightly coat the gasket
surface of the new filter with clean engine oil and hand tighten until the
gasket contacts the base.Then tighten another 1±1/4 to 2 turns.Fill
the crankcase and run the engine to check for leaks.
Continuous contact with USED motor oil has caused cancer in
laboratory mice. Protect your skin by washing with soap and
water.

ENGINE COOLANT
Replacing coolant
A coolant mixture of 50% coolant concentrate and 50% water is
recommended to maintain best overall performance. To avoid damaging
the engine and radiator, the coolant concentrate should not exceed 60%.
When refilling the coolant system either as part of the regular
maintenance (48 months, or 80 000 km [50 000 miles], whichever comes
first and then every 36 months or 48 000 km [30 000 miles], whichever
comes first), or due to service performed, adhere to the following
instructions:
1. Drain and flush the cooling system to remove dirt deposits, oil, rust
particles.
2. Add 1.89L (4 pints) of supplemental coolant additive FW-15, directly
to the cooling system. An additional 237±295 ml (8±10 oz.) of
supplemental coolant additive FW-15 should be added at 24 000 km (15
000 mile) intervals to maintain proper concentration.
3. Fill the coolant reservoir with the specified coolant/water mixture until
the level stabilizes at the top hose fitting. Replace and tighten cap. Fill
the radiator when cold. Level the coolant in the coolant bottle.
4. Reinstall the coolant bottle cap.
5. Start and idle engine until the radiator upper hose is warm
(approximately 10±15 minutes). If the hose does not get warm then
repeat at a higher engine speed.
6. Immediately shut off engine. Cautiously remove coolant bottle cap and
add coolant to Cold Fill mark.
Checking coolant level
Check coolant level in coolant reservoir bottle at least once a month,
only when the engine is cool. Fill to within the ªCold Fill Levelº range
noted on the reservoir as required with a 50/50 mixture of coolant
concentrate and water.
A coolant mixture of 50% coolant concentrate and 50% water is
recommended to maintain best overall performance. A 60/40 antifreeze
to water ratio is acceptable for extremely cold climates, but must be
returned to a 50/50 ratio at the end of the winter season.
Vehicles with diesel engines typically are used to carry heavy loads and
accumulate mileage rapidly. These two factors cause the additives in 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:
²a plugged air inlet system.
²water in the fuel filter/water separator.
²a clogged fuel filter.
²contaminated fuel.
²air in the fuel system, due to loose connections.
²an open or pinched sensor hose.
²low engine oil level.
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.
