WASHER FLUID CHECK
WARNING: If you operate your
vehicle in temperatures below 40°F
(5°C), use washer fluid with antifreeze
protection. Failure to use washer fluid
with antifreeze protection in cold
weather could result in impaired
windshield vision and increase the risk
of injury or accident.
Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See
Capacities and
Specifications (page 281).
State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle ’s paint finish, wiper blades or
washer system.

FILTERS - 6.7L DIESEL WARNING: Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
Your vehicle has two fuel filters. The first
filter mounts on top of the engine on the
left-hand side. The second filter is inside
the diesel fuel conditioner module. The
module is mounted between the inboard
side of the fuel tank and the frame rail. Regular fuel filter changes are an
important part of engine maintenance;
failing to keep with the scheduled
maintenance could lead to engine
performance issues and fuel injection
system damage. See
Scheduled
Maintenance (page 319).
Use only recommended service parts
conforming to specifications. See
Motorcraft Parts
(page 283).
Note: Using fuel that has high levels of
impurities may require more frequent filter
replacements than the service interval
specifies.

Engine-mounted Fuel Filter
Although the fuel system is not fully
pressurized when the vehicle is off, some
residual pressure may remain in the fuel
system since it can take some time for the
pressure to completely bleed off.
Therefore, we recommend you place an
absorbent cloth below the filter connectors
to absorb any fuel that may drain.
The engine-mounted fuel filter is a plastic
disposable cartridge. Removal 1.
Disconnect the fuel lines by squeezing
the connector tabs and pulling the lines
straight off. 2.

ELECTRICAL SYSTEM
INSPECTION
Periodically inspect electrical connectors
on the outside of the cab and on the engine
and frame for corrosion and tightness.
Exposed terminals, 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 Dielectric 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 powertrain components,
such as engine and transmission controls,
instrument panels and ABS. While most
systems operate on battery voltage (12
volts), some systems can be as high as 90
volts or as low as five volts. See the
Electrical Circuit Diagram Manuals,
available from your vehicle ’s manufacturer,
to make sure that any extra body lights and
accessory connections to circuits are both
appropriate and not overloaded. Do not
make modifications to any vehicle control
system without first contacting an
authorized dealer. AIR INDUCTION SYSTEM
INSPECTION WARNING: 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.
Perform a complete inspection of the air
induction system annually.
In areas where road salt is used,
disassemble the joints of each aluminum
component and inspect for salt build-up
and 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 pitting is evident at the joint ends of the
intake pipes, use Motorcraft Silicone
Gasket and Sealant TA-30 to seal the
joints. Make sure no excess material, which
can pull into the engine, is on the inside of
the pipes. If the service condition of the
pipes, hoses or clamps is questionable,
replace the defective part(s).
Make sure to clean all dust and debris out
of the pipes and couplings with a clean,
damp rag before reassembly.
Chassis-mounted Charge Air
Cooler
Visually inspect the core assembly for
debris and clogging of external fins with
the engine off.
247
F650750 (TBC) , enUSA, Edition date: 202010, Second-Printing Maintenance

Before engine operation, remove any debris
blocking the core.
•
Turbocharger-to-charge air cooler.
• Charge air cooler-to-intake manifold
pipe.
• Mounting bracket.
• Chassis-mounted charge air cooler
core.
Inspect air intake piping:
• Check for accumulation of salt
deposits (where applicable). If present,
disassemble and clean the complete
air intake piping system. If pitting is
evident on the intake piping, use
Motorcraft Silicone Gasket and Sealant
TA-30 to seal joints against leakage.
• Check for loose hoses and clamps.
• Check for ruptured or collapsed hoses.
• Check air cleaner housing for cracks.
EXHAUST SYSTEM
INSPECTION
Note: If your vehicle is equipped with a
catalytic converter or muffler, do not blend
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.
If your diesel engine is equipped with a
catalytic converter, it is important to review
the maintenance schedule to make sure
proper functioning of the catalytic
converter. Also, take precautions not to
damage the catalytic converter when
servicing your engine or storing your
vehicle. BRAKE SYSTEM INSPECTION WARNING: Always wear a
respirator approved by the National
Institute of Occupational Studies of
Health (NIOSH) or Mine Safety and
Appliance (MSA) during all brake service
procedures. Wear the respirator from
removal of the wheels through assembly.
Never use compressed air or dry brushing
to clean brake parts or assemblies.
Clean brake parts and assemblies in
open air. During assembly, carefully
place all parts on the floor to avoid
getting dust in the air. Use an industrial
vacuum cleaner with a HEPA filter
system to clean dust from the brake
drums, backing plates and other brake
parts. After using the vacuum, remove
any remaining dust with a rag soaked in
water and wrung until nearly dry.
Never use compressed air or dry
sweeping to clean the work area. Use an
industrial vacuum cleaner with a HEPA
filter system and rags soaked in water
and wrung until nearly dry. Dispose of
used rags with care to avoid getting dust
in the air. Use an approved respirator
when emptying vacuum cleaners and
handling used rags.
Worker clean-up: Wash your hands
before eating, drinking or smoking.
Vacuum your work clothes after use and
then launder them separately, without
shaking them, to prevent fiber dust
getting into the air.
Your vehicle is equipped with
non-asbestos brake linings. However,
exposure to excessive amounts of brake
material (whether asbestos or
non-asbestos, fiberglass, mineral wool,
aramid or carbon) may be a serious health
hazard.

Air Brakes
WARNING: Do not manually adjust
the automatic slack adjusters to correct
excessive push rod stroke as it may result
in reduced brake effectiveness and a
vehicle crash. Excessive push rod stroke
indicates that a problem exists with the
automatic adjuster, with the installation
of the adjuster, or with foundation brake
components that manual adjustment
does not remedy. Seek service from a
qualified facility for excessive push rod
stroke.
Inspection and Adjustment
Establish a regular schedule for periodic
cleaning, lubrication and adjustment
inspection based on vehicle use. Exact
maintenance intervals are difficult to
predetermine due to vehicle applications
and operating conditions. If you are
uncertain of the proper schedule for your
vehicle, contact an authorized dealer.
Regular inspections should include:
• Periodic checking (every service
interval) of push rod travel or brake
adjustment. This is essential for
effective braking. Brake chamber push
rods on original equipment chambers
now incorporate an orange paint
marker near the base of the push rod as a stroke indicator to aid in
adjustment checks. If the push rod is
clean and the brakes are out of
adjustment, you can see the orange
marker protruding from the chamber
when the brakes are applied.
• Checking the brake lining (every service
interval). When brake linings or blocks
wear within 0.063 in (1.6 mm) they
must be replaced.
• Periodic checking (every service
interval) of the air compressor filter.
Check the filter minder and when the
indicator is near or on the red line
marked
Service, replace the filter and
reset the service filter minder.
Do not back off or disconnect the front
brakes so that they are less effective,
letting the rear brakes do all the stopping
of your vehicle. Do not overlook the brakes
on the trailer either. Brake condition on the
trailer is just as important as the tractor.
Proper brake balance on trucks and
tractor-trailers is essential for effective
braking.
Once a year, inspect the entire brake
system:
• Rubber components for deterioration.
A qualified technician should inspect
these components and replace them
as necessary. Replacement intervals
vary according to the severity and
length of vehicle service.
• Condition of brake drums, brake
chambers and slack adjusters.
• System for air leaks.
• Hose or pipes for rust, damage and
deterioration.
• Operation of service and parking
brakes.
Periodically inspect parts such as air brake
chamber diaphragm, air compressor and
air cleaner. Replace any parts if you can
consider them unserviceable.
