You may notice a reduction in vehicle
speed caused by reduced engine power.
In order to manage the engine coolant
temperature. Your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
vehicle loading, grade and ambient
temperature. If this occurs, there is no need
to pull off the road. You can continue to
drive your vehicle.
The air conditioning may automatically
turn on and off during severe operating
conditions to protect the engine from
overheating. When the coolant
temperature decreases to the normal
operating temperature, the air conditioning
turns on.
If the coolant temperature gauge moves
fully into the red zone, or if the coolant
temperature warning or service engine
soon messages appear in your information
display, do the following:
1. Pull off the road as soon as safely
possible and shift the transmission into
park (P).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature
does not drop, follow the remaining
steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue. ENGINE COOLANT CHECK -
6.7L DIESEL 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. Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield. To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure
relief cap. The cooling system is under
pressure. Steam and hot liquid can come
out forcefully when you loosen the cap
slightly. Do not add coolant further than the
MAX
mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 316).
Note: Make sure that the coolant 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.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.

MOUNTED AND DIESEL FUEL
CONDITIONER MODULE FUEL
FILTERS
WARNING
Do not dispose of fuel in the
household refuse or the public
sewage system. Use an authorized
waste disposal facility. Your vehicle has two fuel filters. The first
filter mounts on top of the engine on the
left-hand side. The second filter is inside
the diesel fuel conditioner module. The
module is mounted between the outboard
side of the fuel tank and the frame rail.
Note:
The module is at the front of the fuel
tank or at the front of the aft-axle fuel tank
on some models.
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 316).
Use only recommended service parts
conforming to specifications. See
Motorcraft Parts
(page 255).
Note: Using fuel that has high levels of
impurities may require more frequent filter
replacements than the service interval
specifies.

In areas where road salt is used,
disassemble the joints of each aluminum
component and inspect for salt build-up
and presence of chlorine that can cause
aluminum particles to flake off and enter
the engine combustion chambers. If
evidence of corrosion is found (usually at
the pipe connections), use a wire brush to
clean the inside of the pipes and inside the
rubber hoses.
If pitting is evident at the joint ends of the
intake pipes, use Motorcraft Silicone
Gasket and Sealant TA-30 to seal the
joints. Make sure no excess material, which
can pull into the engine, is on the inside of
the pipes. If the service condition of the
pipes, hoses or clamps is questionable,
replace the defective part(s).
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. 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
219
F-650/750 (TBC) , enUSA, First Printing Maintenance

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. Air Dryer
Climactic conditions affect performance
of desiccant or after-cooler type air dryers.
You must establish a maintenance
schedule for each specific operation.
The use of an air dryer on a vehicle does
not eliminate the need to drain the air
reservoirs periodically.
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 is not an
indication that the dryer is not functioning
properly.
Replace or rebuild the desiccant cartridge
when you determine that the desiccant is
contaminated and does not have adequate
water absorption capacity. The desiccant
change interval may vary. A general
recommendation is to replace the
desiccant 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.
Draining the Air Brake Reservoir
WARNING
Failure to drain air brake reservoirs
can result in a reduction or loss of
braking ability due to fluid
accumulation in the reservoir and/or
possible freeze-up during cold weather. Completely drain all the air brake reservoirs
daily by opening the draincock at the ends
of the tanks. (Where accessible.
Pull-chains are used when the drains are
undercab or otherwise inaccessible.) Close
the draincock after draining. Manually drain
