2011 FORD SUPER DUTY maintenance schedule

Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer toSpecial operating conditionsin the
Scheduled Maintenance Guidechapter.
Trailer towing safety tips
General
•Ensure that the trailer, safety chains and 7–pin electrical connectors
are securely fastened.
•Make sure the truck receiver, draw bar, and coupler are properly
connected and adjusted.
•Check rear view and side mirrors for proper visibility especially when
towing trailer wider than the truck.
•When turning make wide turns to allow trailer tires to properly clear
any obstacles.
•When towing, operate the vehicle at lower speeds than you would
when not towing a trailer. The likelihood of trailer sway is greater at
higher speeds.
•Be prepared for trailer sway due to buffeting when larger vehicles
pass in either direction.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lubricant if not already so
equipped. Refer toMaintenance product specifications and
capacitiesin theMaintenance and Specificationschapter for the
proper axle lubricant. Remember that regardless of the rear axle
lubricant used, do not tow a trailer for the first 500 miles (800 km) of
a new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 km/h) with no full-throttle starts.
Loading
•Trailer loads should be evenly distributed front to back and left to
right.
•Never exceed truck, trailer, receiver, ball, tongue, tire or coupler
loading recommendations.
•Keep the center-of-gravity low for best handling.

•The Total Accessory Reserve Capacity (TARC) is shown on the lower
right side of the vehicle’s Safety Compliance Certification Label. This
applies to Ford-completed vehicles of 10,000 lb. (4,536 kg) GVWR or
less. This is the weight of permanently-attached auxiliary equipment,
such as snowplow frame-mounting hardware, that can be added to the
vehicle and satisfy Ford compliance certification to FMVSS. Exceeding
this weight may require the auxiliary equipment installer additional
safety certification responsibility. The Front Accessory Reserve
Capacity (FARC) is added for customer convenience.
•Rear ballast weight behind the rear axle may be required to prevent
exceeding the FGAWR, and provide front-to-rear weight balance for
proper braking and steering.
•Front wheel toe may require re-adjustment to prevent premature
uneven tire wear. Specifications are found in the FordWorkshop
Manual.
•Headlight aim may require re-adjustment.
•The tire air pressures recommended for general driving are found on
the vehicle’s Safety Certification Label. The maximum cold inflation
pressure for the tire and associated load rating is imprinted on the tire
sidewall. Tire air pressure may require re-adjustment within these
pressure limits to accommodate the additional weight of the snowplow
installation.
•Federal and some local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your authorized dealer for
additional information.
Operating the vehicle with the snowplow attached
Do not use your vehicle for snow removal until it has been driven at
least 500 miles (800 km).
The attached snowplow blade restricts airflow to the radiator, and may
cause the engine to run at a higher temperature: Attention to engine
temperature is especially important when outside temperatures are
above freezing. Angle the blade to maximize airflow to the radiator and
monitor engine temperature to determine whether a left or right angle
provides the best performance.
Follow the severe duty schedule in yourscheduled maintenance
informationfor engine oil and transmission fluid change intervals.

Stowing the flat/spare tire
Note:Failure to follow spare tire stowage instructions may result in
failure of cable or loss of spare tire.
If you are stowing a tire that requires reattaching it to the
vehicle with a tether, perform these steps first, then proceed with
the steps following.
1. Place the tire on end with the
valve stem facing toward the front
of the vehicle.
2. Place the tether into the bolt
holes in the wheel and attach the
lug nut using the lug winch.
3. Lay the tire on the ground with the valve stem facing in the direction
specified on the tire changing instructions located with the jack and
tools.
4. Slide the wheel partially under the vehicle and install the retainer
through the wheel center. Pull on the cable to align the components at
the end of the cable.
5. Turn the jack handle clockwise until the tire is raised to its stowed
position underneath the vehicle. The effort to turn the jack handle
increases significantly and the spare tire carrier ratchets or slips when
the tire is raised to the maximum tightness. Tighten to the best of your
ability, to the point where the ratchet/slip occurs, if possible. The spare
tire carrier will not allow you to overtighten. If the spare tire carrier
ratchets or slips with little effort, take the vehicle to your authorized
dealer for assistance at your earliest convenience.
6. Check that the tire lies flat against the frame and is properly
tightened. Try to push or pull, then turn the tire to be sure it will not
move. Loosen and retighten, if necessary. Failure to properly stow the
spare tire may result in failure of the winch cable and loss of the tire.
7. Repeat this tightness check procedure when servicing the spare tire
pressure (every six months, perscheduled maintenance information),
or at any time that the spare tire is disturbed through service of other
components.
8. If removed, install the spare tire lock (if equipped) into the bumper
drive tube with the spare tire lock key (if equipped) and jack handle.

Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil and filter according to the appropriate schedule
listed in thescheduled maintenance information.
Ford production and Motorcraftreplacement oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraftoil filter or
another with equivalent performance for your engine application.
BATTERY
WARNING:This vehicle
may be equipped with more
than one battery, removal of cable
from only one battery does not
disconnect the vehicle electrical
system. Be sure to disconnect
cables from all batteries when
disconnecting power. Failure to do
so may cause serious personal
injury or property damage.
Your vehicle is equipped with a Motorcraftmaintenance-free battery
which normally does not require additional water during its life of service.
If your battery has a cover/shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time. This will minimize the discharge of your battery
during storage.

ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
intervals listed inscheduled maintenance information.The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -34°F (-36°C). Coolant concentration
testing is possible with a hydrometer or antifreeze tester. The level of
coolant should be maintained at the FULL COLD level or within the
COLD FILL RANGE in the coolant reservoir. If the level falls below, add
coolant per the instructions in theAdding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50/50 mixture of coolant and water provides the following:
•Freeze protection down to -34°F (-36°C).
•Boiling protection up to 265°F (129°C).
