2012 FORD SUPER DUTY fuel cap

COLD WEATHER OPERATION
Changing to a lighter grade engine oil also makes starting easier under
these conditions. Refer toEngine oil specificationsin theMaintenance
and Specificationschapter of this supplement.
Diesel fuel is adjusted seasonally for cold temperatures. Diesel fuel which
has not been properly formulated for the ambient conditions may form
wax crystals which can clog the fuel filters. At temperatures below 20°F
(–7°C), if the engine starts, stalls after a short time, and then will not
restart, the fuel filter(s) may be clogged. For best results in cold
weather, use a diesel fuel which has been formulated for the ambient
conditions. If you have been using biodiesel, you may need to use a fuel
with lower biodiesel content, try another brand, or discontinue using
biodiesel. Do not use alcohol based additives to correct fuel gelling. This
may result in damage to the fuel injectors/system. Use the proper
anti-gel & performance improver product as listed in theMaintenance
product specifications and capacitiessection in theMaintenance and
Specificationschapter.
Your vehicle is equipped with a diesel fuel conditioner module (DFCM)
which recirculates fuel from the engine to help prevent fuel filter
clogging. To avoid engine fuel starvation during cold weather operation
of 32°F (0°C) or below, it is recommended that the fuel level in your
tank should not be allowed to drop below
14full. This will help prevent
air from entering the fuel system and stalling the engine.
Your vehicle is equipped with a an SCR system which uses diesel exhaust
fluid (DEF) to operate properly. DEF must be replenished at certain
intervals. When filling the vehicle’s DEF tank in cold weather, special
care must be taken to prevent damage to the DEF tank. For proper cold
weather fill procedure, seeSelective Catalytic Reduction (SCR) System
in theMaintenance and Specificationschapter.
In cold weather below 32°F (0°C), the engine may slowly increase to a
higher idle speed if left idling in P (Park). As the engine warms-up, the
engine sound level will decrease due to the activation of PCM-controlled
sound reduction features.
If your vehicle is operated in a heavy snow storm or blowing snow
conditions, the engine air induction may become partially clogged with
snow and/or ice. If this occurs, the engine may experience a significant
reduction in power output. At the earliest opportunity, clear all the snow
and/or ice away from inside the air filter assembly. Remove the air
cleaner cover and the pleated paper filter, leaving the foam filter in and
remove any snow or ice. Ensure the foam filter is installed correctly in

specifications. Outside of North America, use fuels meeting EN590 or
equivalent local market standard. 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.
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 meets the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about fuel that meets the World-wide
Fuel Charter.
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.
Diesel fuel conditioner
Additives that will improve fuel cetane numbers may be used to
verify/enhance fuel quality. Use Motorcraftor an equivalent cetane
booster & performance improver as listed in theMaintenance product
specifications and capacitiessection in this chapter. The customer
warranty may be void from using additives that do not meet or exceed
Ford specifications.
Do not use alcohol based additives to correct fuel gelling. This may
result in damage to the fuel injectors/system. Use Motorcraftor an
equivalent anti-gel & performance improver as listed in theMaintenance
product specifications and capacitiessection in this chapter. The
customer warranty may be void from using additives that do not meet or
exceed Ford specifications.
Note:These ultra-low sulfur formulations are designed to meet the
emissions standards for the 6.7L engine and is backward compatible as
well (i.e., can be used in Ford 7.3L, 6.9L, 6.4L and 6.0L diesel engines in
Ford vehicles).
Fueling tips
Truck stops have pumps and nozzles designed for larger, heavy-duty
trucks. When refueling at truck stops: if the nozzle shuts off repeatedly
when refueling, wait 5–10 seconds; then use a slower rate of flow (don’t
depress the nozzle trigger as far).
If air is allowed to enter the fuel system (during fuel filter change or if
you run out of fuel) the engine will purge the trapped air as it runs. To
purge the air sooner: prior to engine start, prime the system by turning

the key to on for 30 seconds then to off. Repeat this several times. The
engine may run rough and produce white smoke while air is in the
system. This is normal and should correct itself in a short time.
An engine that suddenly becomes noisy or operates poorly after a fuel fill
could be using substandard fuel (i.e., high water content, low cetane
rating or gasoline in the fuel). Diesel fuel should be purchased from a
reputable station which sells a large amount of diesel fuel.
Care should be taken whenever diesel fuel is stored. Use only clean,
approved containers which will prevent the entry of dirt or water.
Diesel fuel must not be stored in a galvanized container. The fuel will
dissolve the zinc in a galvanized container. The zinc will then remain in
the solution until it is run through the engine where it will be deposited
in the fuel injectors causing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
This truck is equipped with a fuel fill pipe which is able to accept fuel up
to 20 gallons per minute from a 1
18fuel dispensing nozzle. Pumping fuel
at greater flow rates may result in premature nozzle shut-off or spitback.
Fuel filler cap
Your fuel tank filler cap has an indexed design with a 1/4 turn on/off
feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise 1/4 of a turn until it clicks at least once.
If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The vehicle warranty may
be void for any damage to the fuel tank or fuel system if the
correct genuine Ford or Motorcraftfuel filler cap is not used.
WARNING:The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.

WARNING: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.
Selective Catalytic Reduction (SCR) System
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. The system automatically injects diesel
exhaust fluid (DEF) into the exhaust system to enable proper SCR
function.
Importance of maintaining the DEF level
In order for the SCR system to operate properly, the DEF level must be
maintained. Generally, the DEF tank should be filled during the oil
change service interval. See thescheduled maintenance informationin
this supplement for more information. However, certain conditions or
driving styles, such as trailer towing or fast rates of acceleration, will
require the refilling of the DEF tank more often.
The engine control unit will monitor the amount of fluid available in the
DEF tank. Running a system check in the message center will indicate
whether the DEF level is ok or if it is less than 1/2 full. A message will
automatically be displayed in the message center when the DEF level is
low and needs to be refilled. When you see this message you should refill
your tank. SeeMessage centerin theInstrument Clusterchapter of
yourOwner’s Guidefor message center functions. For instructions on
refilling your DEF tank, seeFilling the DEF tanklater in this section.
DEF warning messages and vehicle operations
WARNING:Diesel Exhaust Fluid (DEF) must be refilled when
low or replaced when contaminated or the vehicle speed will be
speed limited to 50 mph (80 km/h). In these conditions, drive with
caution and refill DEF immediately. If the DEF becomes empty or
contaminated fluid is not replaced, the vehicle will become limited to
idle speed only once stopped. In these conditions, be cautious where
you stop the vehicle because you may not be able to drive long
distances and will not be able to maintain highway speeds until DEF is
refilled or replaced.

Filling the DEF tank
Your vehicle is equipped with a DEF tank with a blue-capped filler port
located next to the diesel fuel fill inlet. The tank can be filled using a
nozzle at a DEF filling station (similar to fuel fill) or using a DEF bottle
with a spout. MotorcraftDEF bottles are recommended as they are
designed to be spill proof and will stop the flow of DEF when the tank is
full. Other aftermarket bottles can be used, but they should have a seal
on the spout and an internal vent tube to achieve best fill performance
and prevent overfilling. Overfilling your DEF tank can cause damage to
the tank. For DEF capacity, seeMaintenance product specifications
and capacitiesin this chapter.
Note:Do not put DEF in the fuel tank. This can cause engine damage
not covered by your vehicle’s warranty.
Note:Immediately wipe away any DEF that has spilled on painted
surfaces with water and a damp cloth to prevent damage to the paint.
You can purchase DEF at your authorized dealer, most highway truck stops
or you can contact roadside assistance for help in finding a retailer that
sells DEF. See theCustomer Assistancechapter in theOwner’s Guidefor
more information. In addition, there is a government website locator for
DEF at the following web address that can be used to find the nearest
location to purchase DEF: http://www.afdc.energy.gov/afdc/locator/def.
Use only DEF certified by the
American Petroleum Institute (API)
such as MotorcraftDEF or
equivalent meeting Ford specification
WSS-M99C130-A and/or ISO 22241.
Look for API certification trademark
shown here. Repairs resulting from
the use of non-certified DEF
products may not be covered by your vehicle’s warranty.
Maintaining the purity of DEF is important to avoid malfunctions in the
SCR system.
If DEF is removed from the tank for repair work, etc., the same DEF
must not be used to refill the tank as its purity is no longer guaranteed.
WARNING:Make sure that DEF does not come into contact
with eyes, skin or clothing. Should DEF contact your eyes, flush
them with plenty of water and contact a physician. Clean affected skin
with soap and water. If DEF is swallowed, drink plenty of water and
contact a physician immediately.

5. Once the level in the DEF bottle
has stopped dropping, return the
container to the vertical position
slightly below the DEF filler port
and let any DEF drain out of the
spout. DO NOT try to continue to
add DEF to the tank by shaking or
repositioning the container to
induce flow. This may cause spilling
and overfill the tank. Overfilling the
DEF tank can cause damage to the
tank.
6. Once the spout has drained, remove the spout from the DEF filler
port and install the blue cap on the DEF filler port.
7. Remove the spout from the DEF container and install the cap back on
the bottle.
8. If the container is empty, discard the empty container, or recycle if
possible. If there is DEF left in the container, retain it for later use. The
spout is re-useable; after use, rinse it with clean water and store the
spout to ensure it is kept clean. Do not use the DEF spout with any
other chemicals.
9. Wipe away any DEF that has spilled on painted surfaces with water
and a damp cloth.
•DEF filling station nozzle fill:
Filling the DEF tank using a nozzle is similar to a normal fuel fill. The
nozzle will shut off automatically when the tank is full. Do not continue
to fill the tank as this may cause spilling and overfill the tank which can
cause damage.
Note:Some filling station nozzles may prevent filling of your DEF tank
due to a magnetic mechanism in the nozzle. This is not a problem with
your vehicle. To refill your tank either locate another filling station or
use a bottle to refill the tank.
Filling the DEF tank in cold climates
DEF will freeze below 12°F (-11°C); however, your vehicle is equipped
with an automatic preheating system which allows the DEF system to
operate below 12°F (-11°C). When the vehicle is not in operation for an
extended period of time with temperatures at or below 12°F (-11°C), the
DEF tank could freeze. If the tank is OVERFILLED and freezes, it could
be damaged, therefore DO NOT OVERFILL.

4. Make sure that the drain valve is fully tightened, then remove the
container from under the vehicle.
Note:A loose drain valve can allow air to enter the fuel system and
cause drivetrain issues. The engine will not operate properly. be sure
that the drain valve is fully tightened.
5. Restart the engine. TheWATER IN FUEL DRAIN FILTERor
WATER IN FUEL DRAIN FILTER SEE MANUALmessage and light
should not be illuminated. If they continues to illuminate, have the fuel
system checked and repaired.
LOW FUEL PRESSURE MESSAGE
The engine is equipped with a low fuel pressure detection system. If the
message center displays:LOW FUEL PRESSUREthe following
explains why and what to do:
•Cold start or cold operation (below 32°F (0°C): If this message
appears during a cold start or during cold operation up to 10 minutes
after the initial cold start, monitor the message center. If it disappears
and does not re-appear after the engine has fully warmed up, the low
fuel pressure message is most likely caused by waxed or gelled fuel.
Do not use alcohol based additives to correct fuel gelling. This may
result in damage to the fuel injectors/systems. Use an anti-gel additive
as listed inMaintenance product specifications and capacities
section in this chapter. The customer warranty may be void from using
additives that do not meet or exceed Ford specifications.
If the low fuel pressure message persistently appears after re-fueling
during the cold start and cold operation conditions defined previously
and then disappear when the engine has fully warmed up, consider
different fuel sources.
•Low fuel operation: If the message appears when the vehicle is warm
and during low fuel tank level operation, i.e. the tank level is at or
very near empty, refuel the vehicle and operate the vehicle. If the
message reappears after fueling, see below. If the message does not
come back, the low fuel pressure condition was due to low fuel levels
in the fuel tank.
•
Normal operation: If the message appears during normal operation when
the vehicle / engine is fully warm, and fuel level is not low, the fuel
filters must be changed regardless of the maintenance schedule interval.
•If replacement of the fuel filter does not remedy the low fuel pressure
message during normal operation as defined above, take the vehicle to
your authorized dealer.

ENGINE OIL
Checking the engine oil level
Because it is normal to add some oil between oil changes, check your
engine oil level each time you stop for fuel. To check the engine oil level
consistently and accurately, the following procedure is recommended:
1. Have engine at normal operating temperature (at least into the
NORMAL range on the engine coolant temperature gauge).
2. Park the vehicle on a level surface, then turn off the engine and open
the hood.
3. Allow at least20 minutesafter engine shutdown to ensure that the
oil contained in the upper parts of the engine has returned to the oil
pan.
4. Protecting yourself from engine heat, pull out the dipstick, wipe it
clean and reinsert fully.
5. Read oil level on both sides of dipstick and use highest level (reading)
for the actual engine oil level.
6. Maintain the oil level within the
crosshatch area on the dipstick by
adding oil as required. Do not
overfill the oil past the maximum
line as depicted by the arrow.
Engine oil specifications
To help achieve acceptable engine performance and durability, it is
important that only engine oils of good quality are used in your diesel
engine and it is changed at the recommended interval. For normal or
severe service, use Motorcraftoil or an equivalent oil conforming to
Ford specifications as listed in theMaintenance product specifications
and capacitiessection in this chapter or API service categories CJ-4 or
CJ-4/SM. It is important to use these oils because they are compatible
with the emission control equipment of your vehicle to meet the more
stringent emission standards.
The use of correct oil viscosities for diesel engines is important for
satisfactory operation. Determine which oil viscosity best suits the
temperature range you expect to encounter for the next service interval
from the following SAE viscosity grade chart.
