•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.
Some parts such as air brake chamber diaphragm, air compressor and air
cleaner should be inspected periodically and replaced if considered
unserviceable.
Air dryer
Performance of desiccant or after-cooler type air dryers is dependent on
climatic conditions in which your vehicle is operating. Maintenance
schedules must be established for each specific operation.
The use of an air dryer on a vehicle does not eliminate the need to
periodically drain the air reservoirs.
Desiccant air dryer
Inspect for moisture in the air system by opening reservoirs, draincocks
or valves and checking for presence of water. The presence of small
amounts of water due to condensation is normal and should not be
considered as an indication that the dryer is not functioning properly.
The desiccant cartridge should be replaced or rebuilt when it has been
determined that the desiccant is contaminated and does not have
adequate water absorption capacity. The desiccant change interval may
vary; it is generally recommended that the desiccant be replaced every
12 months (yearly). If experience has shown that extended or shortened
life has resulted for a particular installation, then the yearly interval can
be increased or decreased accordingly.
Hydraulic brakes
Inspection and adjustment
A regular schedule for periodic cleaning, lubrication, adjustment and
inspection should be established based on the type of vehicle operation.
It is difficult to predetermine an exact maintenance interval (time or
mileage), since vehicles will be used in a wide variety of applications and
conditions. If you are uncertain of the proper schedule and procedures
for your vehicle, contact your dealer.
Inspect the brake lining every maintenance interval. Establish inspection
intervals that provide for lining replacement before damage to the disc
occurs. Excessive lining wear may expose the backing plate to the disc
causing scoring of the disc faces.

Observe the following guidelines when handling fuel:
•Extinguish all smoking materials
and any open flames before
fueling your vehicle.
•Always turn off the vehicle before
fueling.
•Automotive fuels can be harmful
or fatal if swallowed. If fuel is swallowed, call a physician immediately,
even if no symptoms are immediately apparent. The toxic effects of
fuel may not be visible for hours.
•Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
•Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
If you must replace the fuel filler cap, replace it with a genuine
Ford or Motorcraftpart. The customer warranty may be void for
any damage to the fuel tank or fuel system if a genuine Ford or
Motorcraftfuel filler cap is not used.
WARNING:If you do not use the proper fuel filler cap,
excessive pressure or vacuum in the fuel tank may damage the
fuel system or cause the fuel cap to disengage in a collision, which may
result in possible personal injury.
Choosing the right fuel
Use only Ultra Low Sulfur (15 ppm Sulfur Maximum) number 1-D
or 2-D diesel fuel in your diesel engine. The engine and exhaust
system were designed to only use this fuel. Look for the
ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL (15 ppm Sulfur
Maximum) label on fuel pumps when purchasing your fuel.

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.
