functioning of the catalytic converter. Also, take precautions not to
damage the catalytic converter when servicing your engine or storing
your vehicle.
Note:If your vehicle is equipped with a catalytic converter/muffler,do
notblend waste oil with Diesel fuel. Operate only on ultra low sulfur
(less than 15 parts per million sulfur) diesel fuel with a cetane value of
45 or higher.
Air induction system
Once each year, perform a complete inspection of the air induction
system. In areas where road salt is used, the inspection consists of
disassembling the joints of each aluminum component and inspecting for
salt build-up, presence of chlorine that can cause aluminum particles to
flake off and enter the engine combustion chambers.
If evidence of corrosion is found (usually at the pipe connections), use a
wire brush to clean the inside of the pipes and inside the rubber hoses.
If the intake pipes are pitted at the joint ends, use Motorcraft Silicone
Gasket and Sealant TA-30 to seal the joints. Be certain that no excess
material is on the inside of the pipes that can be pulled into the engine.
If the service condition of the pipes, hoses or clamps is questionable,
replace the defective part(s).
Be sure that prior to reassembly all dust and debris has been cleaned out
of the pipes and couplings with a clean, damp rag.
When performing maintenance to any turbocharged engine with
engine air inlet piping disconnected, keep loose clothing, jewelry
and long hair away from the engine air inlet piping. A turbocharger
compressor air inlet protective shield should be installed over the
turbocharger air inlet to reduce the risk of personal injury or death.
Steering - general inspection
•Ask your service technician to examine the steering mechanism. Only
minor adjustments may be necessary.
•Check tie rod, drag link end clamp bolts and ball joints. They must be
tight.
•Check for installation and spread of cotter pins and tightness of nuts
at both ends of the tie rod and drag link.
•Check that pitman arm (steering arm at steering gear) mounting is
tight and locked. Check system for leaks or hose chafing. Repair at
once.

If you must replace the fuel filler cap, replace it with a genuine
Ford or Motorcraft part. The customer warranty may be void for
any damage to the fuel tank or fuel system if a genuine Ford or
Motorcraft fuel filler cap is not used.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel cap to disengage in a collision, which may result in possible
personal injury.
Choosing the right fuel
Use only Ultra Low Sulfur (15 ppm Sulfur Maximum) number 1-D
or 2-D diesel fuel in your diesel engine. The engine and exhaust
system were designed to only use this fuel. Look for the
ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL (15 ppm Sulfur
Maximum) label on fuel pumps when purchasing your fuel.
Number 1-D or winter blend number 2-D fuel is recommended at
temperatures below 20°F (-7°C) (seeCold weather operationin the
Drivingchapter. Diesel fuel containing no more than 5% biodiesel may
be used. Biodiesel fuel is a product that has been converted from
renewable fuel sources, including vegetable oil, animal fat and cooking
oil. Raw or refined vegetable oil, animal fat, cooking oil or recycled
greases should not be used.
Since it is normal for a small amount of unburned fuel to enter the
crankcase and mix with the engine oil, the use of biodiesel requires that
the engine oil and filter be changed more often. Refer to theExceptions
section of theScheduled Maintenance Guidechapter for more
information.
Do not use home heating oil or any diesel fuel not intended for
highway use. Red dye is used to identify fuels intended for
agricultural and non-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.

Using low sulfur (16-500 ppm) or high sulfur (greater than
500 ppm) diesel fuel in a 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.
Using low sulfur (16-500 ppm) or high sulfur (greater than
500 ppm) diesel fuel in a diesel engine designed to use only
Ultra Low Sulfur Diesel fuel will cause certain emission components to
malfunction which may also cause the Service Engine Soon (

light to illuminate indicating an emissions-related concern.
Do not mix diesel fuel with gasoline, gasohol or alcohol. This
could cause an explosion resulting in personal injury.
Do not use starting fluid such as ether or gasoline. Such fluids
can cause immediate explosive damage to the engine and
possible personal injury.
Fuel quality
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel that meets ASTM D 975
specification. Aftermarket additives can damage the injector system or
engine. Repairs to correct the effects of using an aftermarket product in
your fuel may not be covered by your warranty.
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.
Many of the world’s automakers approved the World-wide Fuel Charter
that recommends diesel fuel specifications to provide improved
performance and emission control system protection for your vehicle.
Diesel fuel that meet the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about fuel that meet the World-Wide
Fuel Charter.

When these steps are performed successfully in the order outlined above,
the DPF lamp will begin flashing at a rate of once every 10 seconds. The
engine speed may also increase slightly. To allow parked regeneration to
continue uninterrupted:
1. The vehicle must remain parked
2. The transmission must remain in P (Park) or N (Neutral) (as
previously described in Step 2).
3. The accelerator pedal, service brake pedal, and clutch pedal (if
equipped) must not be depressed
4. The parking brake must remain set
On average (depending on filter level and other factors), the process will
take 20–30 minutes to complete. The DPF lamp will turn off when the
process is complete. Repeat Steps 1–5, if parked regeneration is
interrupted.
To discontinue parked regeneration (Cummins engine only)
Depress any of the floor pedals to discontinue parked regeneration.
Diesel particulate filter maintenance and service
The DPF is designed to retain a relatively large amount of residual ash
and provide many miles and hours of maintenance-free operation. At
some point, generally beyond 150,000 miles (240,000 km) or 5,000 hours
of operation (whichever comes first), the DPF will require professional
cleaning to remove the accumulated ash
The exact number of miles or hours of operation will vary greatly
depending upon vehicle/engine loading and operating conditions, ash
content of the engine oil, and quality of the diesel fuel used in your
truck. Adhering to your engine manufacturer’s recommended oil and fuel
specifications will maximize the miles and hours of operation before a
DPF professional cleaning is required. Refer to your engine
manufacturer’s owner’s manual for more details regarding recommended
maintenance and service of your DPF.
Exhaust outlet assembly
The normal operating temperature of the exhaust system is very
high. Never work around or attempt to repair any part of the
exhaust system until it has cooled. Failure to follow these instructions
may result in personal injury.

shutters should be open during normal operating temperatures.
Engine and Driveline System
•Transmission Enclosure:inspect for cracks, holes, and tears. Clean
any deposits such as oil, dirt, and stones.
•Engine valve covers and block covers are made to damp out engine
mechanical noise and, if needed, should be replaced with
recommended parts. Check for mechanical isolations.
Exhaust System
•Inspect the exhaust system for leaks at various joint connections and
tighten the clamps.
•Do a visual inspection for cracks or holes in the muffler and tail pipe.
•Always use the recommended parts when items need to be replaced.
•The tail pipe elbow or offset tail pipe orientation must not be changed
from the standard position as originally received.
•To avoid abnormal changes in vehicle sound levels, it is necessary for
the owner to perform inspections and necessary maintenance at the
intervals shown in theScheduled Maintenance Guidechapter.

such as the fuel sender, cranking motor, alternator and feed-through
studs should be cleaned and re-coated with a lubricant sealing grease
such as Motorcraft Silicone Brake Caliper Grease and Dielectic
Compound XG-3, or equivalent. This should include the ground cable
connector for batteries, engine and cab as well as the jump starting stud.
Accessory feed connections
Vehicle electrical systems are complex and often include electronic
components such as engine and transmission controls, instrument panels,
ABS, etc. While most systems operate on battery voltage (12 volts),
some systems can be as high as 90 volts or as low as five volts. Refer to
the Electrical Circuit Diagram Manuals, available from your vehicle’s
manufacturer, to ensure that any additional body lights and accessories
are connected to circuits that are both appropriate and not overloaded.
No modification should be made to any vehicle control system without
first contacting your dealer.
SUSPENSION INSPECTION
Note:Do not adjust air suspension height to any setting other than the
specified setting. Altering the height setting will change the driveline
angle and may result in unwarrantable component damage, such as
transmission component damage.
Verify drive axle air suspension height and height control valve
performance at engine lube oil change intervals.
Periodically:
•Check condition of spring leaves for evidence of fatigue, bending or
breakage.
•Check condition of suspension mounting brackets and bushings.
•Check that torque rod mounting fasteners are tight.
•Check to be sure the suspension alignment is maintained at all times.
•Check U-bolts after the chassis has been operating under load for
1,000 miles (1,600 km) or six months, whichever comes first, the
U-Bolt nuts must be re-torqued. The U-Bolt nuts thereafter must be
re-torqued every 36,000 miles (58,000 km). The U-Bolt and nut
threads and seats should be cleaned and lubricated to ensure a “like
new” condition when re-torquing.
Note:See theU-Bolt Nut Torquechart later in this section.
