SCHEDULED MAINTENANCE
The scheduled maintenance services in theGeneral Owner’s
Informationsection of this supplement 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.
FUEL REQUIREMENTS
The engine is designed to use low sulfur number 1–Dor2–D Diesel fuel
only. At temperatures below -7°C (20°F), number 1–D or winter blend
number 2–D fuel is recommended. (SeeCold weather operationin the
Drivingchapter.)
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, engine and
exhaust catalyst 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.

discharged. If there is a clicking or stuttering sound coming from the
engine compartment when you turn the key to START, this may also
indicate a loose or corroded battery connection.
Check the battery connections at the battery posts, cable connection to
the engine grounding point and at the starter connection.
If a discharged battery is suspected, have it checked and corrected.
•For vehicles with manual transmissions, the clutch pedalmustbe fully
depressed in order for the starter to operate.
•For vehicles with automatic transmissions, the gearshift lever must be
in Park or Neutral in order for the starter to operate.
•Try operating the starter switch several times. Should the switch be
corroded, this operation may clean the contacts or make the switch
temporarily operable until you can reach the dealer.
•If all electrical connections are tight and you need assistance to start,
seeJump Startingin theRoadside emergencieschapter of your
owner guide.
If engine cranks but won’t start
Prolonged starter cranking (in excess of 30 seconds) could cause
damage to the starter motor.
•Check the fuel gauge. You may be out of fuel. If the gauge shows that
there is fuel in the tank, the trouble may be in the electrical system or
the fuel system. If equipped with an auxiliary tank, be sure that the
tank control switch is set for the tank with fuel and not on an empty
tank.
•Leaving the ignition key ON for over two minutes without starting may
make starting difficult because the glow plugs will cease activation.
Reset the system by turning the ignition key to OFF and then back to
ON again.
If the engine runs hot
The following could cause the engine to overheat:
•Lack of coolant.
•Dirty cooling system.
•Plugged radiator fins, charge air cooler, A/C condenser and/or oil
cooler.
•Driving with frozen coolant.
•Sticking thermostat.
