NEW VEHICLE BREAK-IN
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1 600 km (1 000 miles) of
new vehicle operation. Vary your speed to allow parts to adjust
themselves to other parts.
Drive your new vehicle at least 800 km (500 miles) before towing a
trailer.
Do not add friction modifier compounds or special break-in oils during
the first few thousand kilometers (miles) of operation, since these
additives may prevent piston ring seating. See ªEngine oilº in the
General Maintenance Informationchapter for more information on oil
usage.

SCHEDULED MAINTENANCE
The Scheduled Maintenance Services in the Service Guide are required
because they are considered essential to the life and performance of
your vehicle.
Use only recommended fuel, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraft parts are designed and
built for best performance in your vehicle.
WASHING THE DIESEL ENGINE
Never wash the engine when it is warm, hot or running. Spraying water
or other cleaning fluids on a warm engine can seriously damage the
engine's fuel system. When washing the engine, the air cleaner must be
in place to prevent water from splashing into the engine.
FUEL REQUIREMENTS
The engine is designed to use low sulfur number 1±D or 2±D diesel fuel
only. At temperatures below -7ÉC (20ÉF), number 1±D or winter blend
number 2±D fuel is recommended. (See ªCold Weather Operationº in the
Startingchapter.)
Do not use fuel intended for agricultural use (agricultural fuel is
dyed red), home heating oil or any diesel fuel not intended for
highway use. Damage to the fuel injection system or engine can
occur if an improper fuel is used.
Do not add gasoline, gasohol or alcohol to diesel fuel. This practice
creates a serious fire hazard and engine performance problems.
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel that meets the ASTM D
975 industry specification. Aftermarket additives can damage the injector
system or engine.
Do not blend used engine oil with diesel fuel under any circumstances.
Blending used oil with the fuel will significantly increase your vehicle's
exhaust emissions and reduce engine life due to increased internal wear.
Do not crank the engine for more than 30 seconds at a time as
damage to the starter motor may result.
If the engine fails to start in 30 seconds, turn the key to the OFF
position and wait 30 seconds before trying again.

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
