Resonator and Tailpipe Assembly
Maintenance WARNINGS
Failure to maintain the functional
holes, in the tailpipe section of the
exhaust, clean and free of debris or
foreign material may result in the holes
becoming blocked or plugged. Do not
modify or remove the tail-pipe section.
Blocked or plugged holes or
removal/modification of the system could
result in elevated exhaust gas
temperatures which may result in
vehicle/property damage or personal
injury. The normal operating temperature
of the exhaust system is very high.
Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the diesel oxidation
catalytic converter and/or the diesel
particulate filter (DPF). The diesel
oxidation catalytic converter and/or the
DPF heats up to a high temperature after
only a short period of engine operation and
can stay hot even after the engine is turned
off. Failure to follow these instructions may
result in personal injury. Note:
Additions of aftermarket devices or
modifications to the exhaust system can
reduce the effectiveness of the exhaust
system as well as cause damage to the
exhaust system or engine. These actions
may also affect your vehicle ’s warranty. See
the Warranty Guide for more information. The diesel resonator tail-pipe assembly is
a uniquely functioning device that
accompanies the diesel particulate filter
assembly. The tail-pipe assembly serves
multiple functions. First, it serves as an
acoustic device to attenuate exhaust noise.
Second, it provides an exit path for the
exhaust from your vehicle. It also helps
control the temperature of the exhaust
during diesel particulate filter regeneration
events. The visible holes in each leg of the
twin tip and the holes under the shield just
inboard of the right rear tire(s) are
functional. You need to keep the holes
clear of mud, debris or foreign material to
maintain proper function of the exhaust
system. Clean and remove debris or foreign
material if present as needed. Spraying
with a hose during regular washing of your
vehicle should help keep holes clean and
clear of debris or foreign material.
Emission Control System Laws
WARNING
Do not remove or alter the original
equipment floor covering or
insulation between it and the metal
floor of the vehicle. The floor covering and
insulation protect occupants of the vehicle
from the engine and exhaust system heat
and noise. On vehicles with no original
equipment floor covering insulation, do not
carry passengers in a manner that permits
prolonged skin contact with the metal
floor. Provide adequate insulation. Failure
to follow these instructions may result in
fire or personal injury. In the U.S. federal law and certain state
laws prohibit removing or rendering
inoperative emission control system(s).
Similar federal or provincial laws may
apply in Canada. Ford recommends
against any vehicle modification without
determining applicable law.

Tampering with emissions
control systems (including
related sensors and the Diesel
Exhaust Fluid (DEF) injection system) can
result in reduced engine power and the
illumination of the service engine soon
light.
Tampering With a Noise Control
System
Federal law prohibits the following acts:
• The removal or rendering inoperative
by any person other than for purposes
of maintenance, repair or replacement
of any device or element of design
incorporated into any new vehicle for
the purpose of noise control prior to its
sale or delivery to the ultimate
purchaser or while it is in use
• The use of the vehicle after such device
or element of design has been removed
or rendered inoperative by any person.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer ’s
specifications.
The complexity of the diesel engine makes
it so you are not encouraged to carry-out
maintenance other than the services
described in this Owner's Manual. If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
•
A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note: If these checks do not help you
correct the concern, have your vehicle
checked by an authorized dealer.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lbs. (4,536
kg) GVWR (Gross Vehicle Weight Rating).
The preceding statements concerning
prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lbs. (4,536 kg) GVWR.

•
Do not rest your foot on the brake
pedal while driving.
• Avoid carrying unnecessary weight.
• Avoid adding particular accessories to
your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski
racks).
• Avoid driving with the wheels out of
alignment.
COLD WEATHER
PRECAUTIONS
The functional operation of some
components and systems can be affected
at temperatures below -13°F (-25°C).
DRIVING THROUGH WATER WARNING
Do not drive through flowing or deep
water as you may lose control of your
vehicle.
Note:
Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
FLOOR MATS WARNINGS
Always use floor mats that are
designed to fit the foot well of your
vehicle. Only use floor mats that
leave the pedal area unobstructed. Only
use floor mats that are firmly secured to
retention posts so that they cannot slip out
of position and interfere with the pedals
or impair safe operation of your vehicle in
other ways. Pedals that cannot move freely can
cause loss of vehicle control and
increase the risk of serious personal
injury.

Checking the Engine Coolant
When the engine is cold, check the
concentration and level of the engine
coolant at the intervals listed in the
scheduled maintenance information. See
Scheduled Maintenance (page 363).
Note: Make sure that the level is between
the MIN and MAX marks on the coolant
reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately. See
Adding Engine Coolant
in this chapter.
The coolant concentration should be
maintained within 48% to 50%, which
equates to a freeze point between -30°F
(-34°C) and -34°F (-37°C).
Note: For best results, coolant
concentration should be tested with a
refractometer, for example Robinair®
Coolant and Battery Refractometer 75240.
We do not recommend the use of
hydrometers or coolant test strips for
measuring coolant concentrations.
Note: Automotive fluids are not
interchangeable. Do not use engine coolant,
antifreeze or windshield washer fluid outside
of its specified function and vehicle location.
Adding Engine Coolant WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling
system can burn you badly. Also, spilling
coolant on hot engine parts can burn you.
