Filling the DEF tank
Your vehicle is equipped with a DEF tank with a blue-capped filler port
The 5 gallon (19.0L) DEF tank is located on the left side of the vehicle
under the cab and the 9 gallon (34.0L) DEF tank is located on the right
side of the vehicle behind the Regular Cab and Super Cabs and under the
Crew Cab. 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. Motorcraftbrand
DEF bottles are recommended. Other aftermarket bottles can be used but
it should have a seal on the spout and an internal vent tube to achieve best
fill performance and prevent overfilling.

7. Clean and install the filler plug securely.
CHASSIS-MOUNTED CHARGE AIR COOLER
Inspect charge air cooler daily
With the engine off, visually inspect the charge air cooler core assembly
for debris and clogging of external fins. Prior to 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 the
intake piping is pitted, use MotorcraftSilicone 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.
ELECTRICAL SYSTEM INSPECTIONS
Periodically inspect electrical connectors on the outside of the cab, 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 MotorcraftSilicone Brake Caliper Grease and Dielectic
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,
ABS, etc. While most systems operate on battery voltage (12 volts),
some systems can be as high as 90 volts or as low as five volts. Refer to
the Electrical Circuit Diagram Manuals, available from your vehicle’s
manufacturer, to ensure that any additional body lights and accessories
are connected to circuits that are both appropriate and not overloaded.
No modification should be made to any vehicle control system without
first contacting your dealer.

Irregular wear can be minimized by:
•Using the right inflation pressure for the load being carried.
•Maintaining proper front wheel alignment -especially toe-in-to
specifications.
•Maintaining proper tire and wheel balance.
•Maintaining shock absorbers and suspension components.
Use of tire chains
Refer to chain manufacturer’s recommendation for correct tire chain
usage, installation and removal.

Among those acts presumed to constitute tampering are the following
acts listed:
Vehicle System Acts
Acoustical
ShieldingRemoval of noise shields, hood blanket, tunnel liner
or acoustical absorptive material.
Engine Removal or rendering inoperative the engine speed
governor so as to allow engine speed to exceed
manufacturer specifications. Removal of engine
mounted noise shield or oil pan enclosure.
Engine Air
Induction SystemRemoval of the air duct, silencer, air cleaner, and/or
air cleaner element and baffle in air cleaner;
re-indexing of air cleaner.
Exhaust System Removal or rendering inoperative exhaust system
components including the catalytic converter -
muffler assembly, inlet pipe, outlet pipe, resonator
and flexpipe. Rotation of horizontal exhaust system
directional outlet pipe to cause the exhaust to be
emitted in a direction other than the orientation the
vehicle was originally produced with.
Engine Cooling
SystemRemoval or rendering inoperative the fan clutch.
Removal or modification of the fan shroud.
Replacing a fixed fan with a fan of increased
diameter, different number of blades or different
pitch width.
DEF (Diesel
exhaust fluid)
SystemRemoval or rendering inoperative DEF system
components including the DEF tank, dosing module,
dosing supply module, dosing control unit, NOx
electronic module or NOx sensor.
Emissions control system(s) laws
Federal law prohibits vehicle manufacturers, dealers and other persons
engaged in the business of repairing, servicing, selling, leasing or trading
motor vehicles, as well as fleet operators from knowingly removing or
rendering an emissions control device or system inoperative. Further,
modifications of the emissions control system(s) could create liability on
the part of individual owners under the laws of some states. In Canada,
modification of the emissions control system could create liability under
applicable Federal or Provincial laws.
