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

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.
255
Maintenance

• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.
To clean the windshield and wiper blades:
• Clean the windshield with a
non-abrasive glass cleaner. When
cleaning the interior of the windshield,
avoid getting any glass cleaner on the
instrument panel or door panels. Wipe
any glass cleaner off these surfaces
immediately.
• For windshields contaminated with
tree sap, chemicals, wax or bugs, clean
the entire windshield using steel wool
(no greater than 0000 grade) in a
circular motion and rinse with water.
• Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate.
Note: Do not use razor blades or other
sharp objects to clean or remove decals
from the inside of the heated rear window.
The vehicle warranty does not cover
damage caused to the heated rear window
grid lines.
CLEANING THE INTERIOR
WARNING: Do not use cleaning
solvents, bleach or dye on the vehicle's
seatbelts, as these actions may weaken
the belt webbing.
WARNING: On vehicles equipped
with seat-mounted airbags, do not use
chemical solvents or strong detergents.
Such products could contaminate the
side airbag system and affect
performance of the side airbag in a crash.
For fabric, carpets, cloth seats and seats
equipped with side airbags:
• Remove dust and loose dirt with a
vacuum cleaner.
• Remove light stains and soil with
Motorcraft Professional Strength
Carpet & Upholstery Cleaner.
• If grease or tar is present on the
material, spot-clean the area first with
Motorcraft Spot and Stain Remover. In
Canada, use Motorcraft Multi-Purpose
Cleaner.
• If a ring forms on the fabric after spot
cleaning, clean the entire area
immediately (but do not oversaturate)
or the ring will set.
• Do not use household cleaning
products or glass cleaners, which can
stain and discolor the fabric and affect
the flame retardant abilities of the seat
materials.
Mirrors
Do not clean the housing or glass of any
mirror with harsh abrasives, fuel or other
petroleum or ammonia-based cleaning
products.

Capacities and Specifications

There are three types of maintenance
intervals for general vehicle environments:
On-Highway, City and Severe Service. In
all applications, monitoring miles
(kilometers) and time and when the engine
is due for an oil change determine the
actual interval. When the engine oil change
is required before the truck lubrication
interval, perform the lubrication at the
same time in order to reduce your vehicle’s
time out of service.
Air Brake Adjustment
WARNING: Failure to maintain
proper air brake adjustment can result
in reduction or loss of braking ability.
A qualified service technician, keeping to
the instructions in the service manual,
should perform air brake inspection and
adjustment or repairs.
Cam Brakes - Automatic Slack
Adjusters
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.
Inspect standard air brakes equipped with
automatic slack adjusters for proper brake
adjustment as listed in the maintenance
schedule charts.
However, inspect the brakes more
frequently when subjecting them to heavy
use or adverse operating conditions such
as:
• Frequent brake applications while fully
loaded.
• Operation on hilly or mountainous
terrain.
• Frequent operation on dirt, gravel or
mud.
Some aftermarket brake linings also
require more frequent inspections.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.
Check Every Month
Air filter restriction gauge.1
Engine oil level.
Fuel and water separator. Drain if necessary, or if indicated by the information display.
