2008 FORD SUPER DUTY engine

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:
•a plugged air inlet system or engine air filter element.
•water in the fuel filter/water separator.
•a clogged fuel filter.
•contaminated fuel.
•air in the fuel system, due to loose connections.
•an open or pinched sensor hose.
•low engine oil level.
•wrong fuel or oil viscosity for climactic conditions.
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. The engine is
designed to run roughly as the fuel tank nears Empty. This is a warning
to the driver to add fuel as soon as possible. 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.

MINOR TROUBLESHOOTING GUIDE
Air purge procedure
Turn the key on for 30 seconds, then turn off. Repeat procedure four or
five times.
If the engine won’t crank
Turn on the headlights. If the lights are dim, do not go on at all or when
the ignition is turned to START the lights become dim or go out, the
battery connections may be loose or corroded, or the battery may be
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.
Battery posts, terminals and related accessories contain lead and
lead compounds.Wash hands after handling.
•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 P (Park) or N (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,
refer toJump startingin theRoadside Emergencieschapter of your
Owner’s Guide(F-Super Duty) or refer to theJump startingsection
in theRoadside Emergencieschapter of this supplement (E-Series).
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 turned to 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.
•Overloading or pulling heavy trailers during hot weather.
•Grill or radiator air blockage.
•Slipping or missing drive belt.
•Plugged or very dirty air filter.
If fuses burn out
Burned-out or blown fuses usually indicate an electrical short-circuit,
although a fuse may occasionally burn out from vibration. Insert a second
fuse. If this fuse immediately burns out and you cannot locate the cause,
return your vehicle to your dealer for a circuit check.
Replacement fuses and circuit breakers must always be the same
rating as the original equipment shown. Never replace a fuse or
circuit breaker with one of a higher rating. Higher rated fuses or circuit
breakers could allow circuit overloading in the event of a circuit
malfunction, resulting in severe vehicle damage or personal injury due
to fire.
Refer to theOwner’s Guidefor replacement of fuses.

SCHEDULED MAINTENANCE GUIDE
Vehicle Identification Number (VIN):
Owner Name:
Address:
Note:Use only a 6.4L diesel engine that has been configured for use with
high sulfur diesel fuel in markets with diesel fuel that has sulfur content
greater than 15 ppm. Using low sulfur diesel fuel (16–500 ppm) or high
sulfur diesel fuel (greater than 500 ppm) in a 6.4L diesel engine
designed to use only Ultra Low Sulfur Diesel fuel increases the likelihood
of engine oil dilution with fuel which may lead to major engine damage.
Vehicles that are operated in high sulfur diesel fuel markets must be
configured for the high sulfur fuel and require a different maintenance
schedule.
GENERAL MAINTENANCE INFORMATION
Why maintain your vehicle?
This guide describes the scheduled maintenance required for your
vehicle. Carefully following this schedule helps protect against major
repair expenses resulting from neglect or inadequate maintenance and
may also help to increase the value of your vehicle when you sell or
trade it.
It is your responsibility to see that all scheduled maintenance is
performed and that the materials used meet Ford engineering
specifications. Failure to perform scheduled maintenance in this guide
will invalidate warranty coverage on parts affected by the lack of
maintenance. Be sure receipts for completed maintenance are kept with
the vehicle and confirmation of the work performed is always recorded in
this guide.
Your Ford or Lincoln Mercury dealer, or Ford or Lincoln Mercury Quality
Care Center has factory trained technicians who can perform the

required maintenance using genuine Ford parts. They are committed to
meeting your service needs and to assuring your continuing satisfaction.
Protecting your investment
Maintenance is an investment that will pay dividends in the form of
improved reliability, durability and resale value. To ensure the proper
performance of your vehicle and its emission control systems, it is
imperative that scheduled maintenance be completed at the designated
intervals.
Your vehicle is very sophisticated and built with multiple complex
performance systems. Every manufacturer develops these systems using
different specifications and performance features. That’s why it’s
important to rely upon your Ford or Lincoln Mercury dealership to
properly diagnose and repair your vehicle.
Ford Motor Company has recommended maintenance intervals for
various parts and component systems based upon engineering testing.
Ford Motor Company relies upon this testing to determine the most
appropriate mileage for replacement of oils and fluids to protect your
vehicle at the lowest overall cost to you and recommends against
maintenance schedules that deviate from the scheduled maintenance
information.
Ford strongly recommends the use of genuine Ford replacement parts.
Parts other than Ford, Motorcraft or Ford authorized remanufactured
parts that are used for maintenance replacement or for the service of
components affecting emission control must be equivalent to genuine
Ford Motor Company parts in performance and durability. It is the
owner’s responsibility to determine the equivalency of such parts. Please
consult yourWarranty Guidefor complete warranty information.
Non-Ford approved chemicals or additives are not required for factory
recommended maintenance. In fact, Ford Motor Company recommends
against the use of such additive products unless specifically
recommended by Ford for a particular application.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic of
the chemical compound and may not necessarily demonstrate that a fluid
needs to be changed. Oils and fluids identified in this guide should be
changed at the specified interval or in conjunction with a repair. Flushing
is a viable way to change fluid for many vehicle sub-systems during
scheduled maintenance and should only be done using the same fluid
required to finish the maintenance procedure, or a Ford approved
flushing chemical.

Engine Emissions label
Emissions information appears on the Engine Emissions label on the
engine valve cover. This decal identifies engine displacement and
provides certain engine specifications.
Any modification of the emissions control system could create liability
under federal law (U.S.) if made prior to sale and registration, under the
laws of some states if made thereafter. Further, federal law prohibits
vehicle manufacturers, dealers and other persons engaged in the
business of repairing, servicing, selling, leasing or trading motor vehicles
as well as fleet operations from knowingly removing or rendering an
emissions control system inoperative after sale and delivery to an
ultimate purchaser. In Canada, modifications of the emissions control
system could create liability under applicable federal or provincial laws.
