CHANGING THE ENGINE-
MOUNTED AND DIESEL FUEL
CONDITIONER MODULE FUEL
FILTERS - 6.7L DIESEL
Your vehicle has two fuel filters. The first
filter mounts on top of the engine on the
left-hand side. The second filter, inside the
diesel fuel conditioner module, is mounted
on the frame rail inboard of the fuel tank,
between the frame rail and the drive shaft.
You should replace both filters at the same
time. 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 314).
Refer to Motorcraft part numbers in the
Capacities and Specifications chapter for
the fuel filter replacement part number.
See
Motorcraft Parts (page 252). This
part number includes filters and seals for
both the engine-mounted and
frame-mounted filters.
Diesel Fuel Conditioner Module
Filter
Removal
The diesel fuel conditioner module filter is
located in the lower portion of the housing.
1. Drain the diesel fuel conditioner module. See Draining the Fuel and
Water Separator earlier in this chapter.
2. Remove the lower portion of the diesel
fuel conditioner module housing (filter
bowl) by turning it counterclockwise
using a 32 mm socket. Note:
Depending on the amount of seal
swelling, removal of the filter bowl may be
noisy and require some effort. Replace the
seal prior to reinstalling the filter bowl to
improve assembly.
3. Remove and discard the old fuel filter element.
4. Carefully clean the mating surfaces using a lint-free rag.
Installation
1. Install the new filter into the filter bowl
tabs and replace the seal on the diesel
fuel conditioner module header (top
portion of separator). Refer to
Motorcraft part numbers in the
Capacities and Specifications chapter
for the fuel filter kit part number. See
Motorcraft Parts
(page 252).
2. Lube O-ring with lubricant packet in the filter kit. This will assist in making
sure the filter is properly tightened.

3. Reinstall the lower portion of the
housing by slowly turning it clockwise
onto diesel fuel conditioner module
housing, allowing fuel to soak into the
fuel filter element. Tighten the lower
housing until it contacts the
mechanical stop.
Note: The engine will not run properly if you
do not install the diesel fuel conditioner
module fuel filter in the housing or if the
filter bowl is not tightened to the
mechanical stop.
Note: You will need to purge the system of
air after removal or changing of the filter.
See Purging Air from the Fuel System later
in this chapter.
Engine-mounted Fuel Filter
Removal
The engine-mounted fuel filter is a plastic
disposable cartridge. 1.
Disconnect both fuel lines by squeezing
the connector tabs and pulling the lines
straight off. Note:
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 a shop rag below
the filter connectors to absorb the small
amount of fuel that will drain.
2. Rotate the filter fully counterclockwise
until the peg is at the far end of the slot.
3. Pull the filter straight up from the bracket and discard the filter.
Installation
1. Install the new filter into the filter bracket. Turn the filter clockwise to
lock it in place.

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.
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. 218

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.

Follow the tire manufacturer's
recommended cold inflation pressure for
the tire size, load range (ply rating) and
steer axle loading typical for their operation
(each steer axle tire equals ½ steer axle
loading).
Special applications may warrant a setting
based on experience with the type of tire
operating loads and conditions. Radial tires
are more sensitive to toe-in setting than
bias ply tires. Fine tuning school bus
alignment to line-haul truck standards
does not drastically improve tire tread life.
STEERING SYSTEM
INSPECTION
WARNING
Failure to maintain the steering
system in proper condition can cause
reduced steering ability resulting in
property damage, personal injury or death. Note:
Have any steering problems
immediately corrected by a qualified service
technician.
Ask your service technician to examine the
steering mechanism. Only minor
adjustments may be necessary.
Regular inspections should include:
• Checking the tie rod, drag link end
clamp bolts and ball joints for proper
tightness.
• Checking for installation and spread of
cotter pins and tightness of nuts at
both ends of the tie rod and drag link.
• Checking that the pitman arm (steering
arm at steering gear) mounting is tight
and locked. Check system for leaks or
hose chafing. Repair immediately, if
necessary. •
Maintaining proper steering gear and
power steering pump lubricant levels.
• Checking steering column joint bolts
and steering linkage, particularly for
body-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, check
steering column joint bolt tightness every
60,000 mi (96,000 km) or annually,
whichever occurs first. Do not overtighten
the bolts.
Hydraulic System
Whenever draining and refilling the power
steering's hydraulic system for any reason,
bleed air from the system before returning
the vehicle to service. Failure to bleed the
hydraulic system properly can result in
degradation of power system performance.
Consult an authorized dealer who is aware
of the proper procedures for filling and
bleeding the system.
SUSPENSION SYSTEM
INSPECTION
Note: Do not adjust air suspension height
to any setting other than the specified
setting. Altering the height setting changes
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
oil change intervals.
Periodically check:
• Condition of spring leaves for evidence
of fatigue, bending or breakage.
• Condition of suspension mounting
brackets and bushings.
• Torque rod mounting fasteners for
tightness.

Note:
Never use abrasive materials, for
example steel wool or plastic pads as they
can scratch the chrome surface.
Note: Do not use chrome cleaner, metal
cleaner or polish on wheels or wheel covers.
Exterior Plastic Parts
For routine cleaning we recommend
Motorcraft Detail Wash. If tar or grease
spots are present, we recommend
Motorcraft Bug and Tar Remover.
Stripes or Graphics (If Equipped)
Do not use a commercial or high-pressure
sprayer on the surface or edge of stripes
and graphics. This can damage them and
cause the edges to peel away from the
vehicle surface.
Underbody
Flush the complete underside of your
vehicle frequently. Keep body and door
drain holes free of debris or foreign
material.
WAXING
Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.
When washing and waxing, park your
vehicle in a shaded area out of direct
sunlight. Always wash your vehicle before
applying wax.
• Use a quality wax that does not contain
abrasives.
• Follow the manufacturer ’s instructions
to apply and remove the wax.
• Apply a small amount of wax in a
back-and-forth motion, not in circles. •
Do not allow wax to come in contact
with any non-body (low-gloss black)
colored trim. The wax will discolor or
stain the parts over time.
•Roof racks.
• Bumpers.
• Grained door handles.
• Side moldings.
• Mirror housings.
• Windshield cowl area.
• Do not apply wax to glass areas.
• After waxing, your car's paint should
feel smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
When washing:
• Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold
water to avoid cracking the engine
block or other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
