    ENGINE COOLANT CHECK -
    6.8L 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.

    							WARNINGS
    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.
    Adding Coolant WARNING
    Never remove the coolant reservoir
    cap while the engine is running or hot.
    Note:
    Automotive fluids are not
    interchangeable. Do not use coolant or
    windshield washer fluid outside of its
    specified function and vehicle location. Note:
     Do not use stop leak pellets, cooling
    system sealants, or non-specified additives
    as they can cause damage to the engine
    cooling or heating systems.  Resulting
    component damage may not be covered by
    the vehicle Warranty.
    It is very important to use prediluted
    coolant approved to the correct
    specification in order to avoid plugging the
    small passageways in the engine cooling
    system.  See 
    Capacities and
    Specifications (page 258).  Do not mix
    different colors or types of coolant in your
    vehicle. Mixing of engine coolants or using
    an incorrect coolant may harm the engine
    or cooling system components and may
    not be covered by the vehicle Warranty.
    Note: Coolants marketed for all makes and
    models may not be approved to Ford
    specifications and may cause damage to
    the cooling system. Resulting component
    damage may not be covered by the vehicle
    Warranty.
    If the coolant level is at or below the
    minimum mark, add prediluted coolant
    immediately.
    For vehicles with overflow coolant systems
    with a non-pressurized cap on the coolant
    recovery system, add coolant to the
    coolant recovery reservoir when the engine
    is cool. Add prediluted coolant to the
    maximum level. For all vehicles which have
    a coolant degas system with a pressurized
    cap, or if it is necessary to remove the
    coolant pressure relief cap on the radiator,
    follow these steps to add engine coolant:
    1. Turn the engine off and let it cool.
    2. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
    3. Fill the coolant reservoir slowly with prediluted engine coolant to within the
    minimum and maximum range on the
    engine coolant reservoir. If you
    removed the radiator cap in an
    overflow system, fill the radiator until
    190
    F-650/750 (TBC) , enUSA, First Printing Maintenance 
    						
    							the coolant is visible and the radiator
    is almost full. If coolant is added to
    bring the level within the minimum and
    maximum range when the engine is not
    cold, the system may remain
    underfilled.
    4. Replace the coolant reservoir cap, turn
    it clockwise until you feel a strong
    resistance.
    5. Check the coolant level in the coolant reservoir the next few times you drive
    your vehicle. If necessary, add enough
    prediluted engine coolant to bring the
    coolant level to the proper level.
    Note: If prediluted coolant is not available,
    use the approved antifreeze concentrate
    diluting it to 50/50 with distilled water.  See
    Capacities and Specifications (page 258).
    Using water that has not been deionised
    may contribute to deposit formation,
    corrosion or plugging of the small cooling
    system passageways.
    If you have to add more than 1.1 qt (1 L) of
    engine coolant per month, have your
    vehicle checked as soon as possible.
    Operating an engine with a low level of
    coolant can result in engine overheating
    and possible engine damage.
    Note: During normal vehicle operation, the
    coolant may change color from orange to
    pink or light red. As long as the coolant is
    clear and uncontaminated, this color change
    does not indicate the coolant has degraded
    nor does it require the coolant to be drained,
    the system to be flushed, or the coolant to
    be replaced. Note:
    In case of emergency, you can add a
    large amount of water without coolant in
    order to reach a vehicle service location.
    Water alone, without coolant, can cause
    engine damage from corrosion, overheating
    or freezing. When you reach a service
    location, you must have the cooling system
    drained, flushed and refilled using the
    correct specification prediluted coolant or
    antifreeze concentrate.  See 
    Capacities and
    Specifications (page 258).
    Do not use the following as a coolant
    substitute:
    • Alcohol.
    • Methanol.
    • Brine.
    • Any coolant mixed with alcohol or
    methanol antifreeze.
    Alcohol and other liquids can cause engine
    damage from overheating or freezing.
    Do not add extra inhibitors or additives to
    the coolant. These can be harmful and
    compromise the corrosion protection of
    the coolant.
    Recycled Coolant
    We do not recommend the use of recycled
    coolant as an approved recycling process
    is not yet available.
    Dispose of used engine coolant in an
    appropriate manner. Follow your
    community ’s regulations and standards
    for recycling and disposing of automotive
    fluids.
    191

    							Severe Climates
    If you drive in extremely cold climates:
    •
    It may be necessary to increase the
    coolant concentration above 50%.
    • A coolant concentration of 60%
    provides improved freeze point
    protection. Coolant concentrations
    above 60% decrease the overheat
    protection characteristics of the
    coolant and may cause engine
    damage.
    If you drive in extremely hot climates:
    • You can decrease the coolant
    concentration to 40%.
    • Coolant concentrations below 40%
    decrease the freeze and corrosion
    protection characteristics of the
    coolant and may cause engine
    damage.
    Vehicles driven year-round in non-extreme
    climates should use prediluted engine
    coolant for optimum cooling system and
    engine protection.
    Coolant Change
    At specific mileage intervals, as listed in
    the scheduled maintenance information,
    the coolant should be changed. The
    information display may display a message
    to change coolant at this time. Add
    prediluted coolant approved to the correct
    specification.  See Capacities and
    Specifications (page 252). Engine-driven Cooling Fan (Fan
    Clutch)
    Your vehicle is equipped with an engine
    driven cooling fan drive (also called a fan
    clutch). This fan drive changes the fan
    speed to match the vehicle
    ’s changing
    cooling air flow requirements. Fan speed,
    fan noise level and fuel consumption all
    will increase based on the driving
    conditions that include trailer towing, hill
    climbing, heavy loads, high speed and high
    ambient temperature, individually or in
    combination.
    The fan drive is designed to provide the
    minimum fan speed (and resulting
    minimum fan noise and fuel consumption)
    required to meet the ever changing vehicle
    cooling air flow requirements. You will hear
    the amount of fan noise increasing and
    decreasing as the engine power
    requirements and vehicle driving conditions
    change as you drive. This is to be expected
    as being normal to the operation of your
    vehicle. High levels of fan noise might also
    be heard when your engine is first started,
    and should normally decrease after driving
    for a short time.
    Fail-Safe Cooling
    Fail-safe cooling allows you to temporarily
    drive your vehicle before any incremental
    component damage occurs. The fail-safe
    distance depends on ambient
    temperature, vehicle load and terrain.
    How Fail-Safe Cooling Works
    If the engine begins to overheat, the
    coolant temperature gauge moves toward
    the red zone: A warning lamp illuminates and
    a message may appear in the
    information display.
    192
    F-650/750 (TBC) , enUSA, First Printing Maintenance   
    						
    							If the engine reaches a preset
    over-temperature condition, the engine
    automatically switches to alternating
    cylinder operation. Each disabled cylinder
    acts as an air pump and cools the engine.
    When this occurs, your vehicle still
    operates, however:
    •
    Engine power is limited.
    • The air conditioning system turns off.
    Continued operation increases the engine
    temperature, causing the engine to
    completely shut down.  Your steering and
    braking effort increases in this situation.
    When the engine temperature cools, you
    can re-start the engine. Have your vehicle
    checked as soon as possible to minimize
    engine damage.
    When Fail-Safe Mode Is Activated WARNINGS
    Fail-safe mode is for use during
    emergencies only. Operate your
    vehicle in fail-safe mode only as long
    as necessary to bring your vehicle to rest
    in a safe location and seek immediate
    repairs. When in fail-safe mode, your
    vehicle will have limited power, will not be
    able to maintain high-speed operation, and
    may completely shut down without
    warning, potentially losing engine power,
    power steering assist, and power brake
    assist, which may increase the possibility
    of a crash resulting in serious injury. Never remove the coolant reservoir
    cap while the engine is running or hot.
    Your vehicle has limited engine power
    when in the fail-safe mode, drive your
    vehicle with caution. Your vehicle does not
    maintain high-speed operation and the
    engine may operate poorly.
    Remember that the engine is capable of
    automatically shutting down to prevent
    engine damage.  In this situation: 1. Pull off the road as soon as safely
    possible and switch the engine off.
    2. If you are a member of a roadside assistance program, we recommend
    that you contact your roadside
    assistance service provider.
    3. If this is not possible, wait a short period for the engine to cool.
    4. Check the coolant level. If the coolant level is at or below the minimum mark,
    add prediluted coolant immediately.
    5. When the engine temperature cools, you can re-start the engine. Have your
    vehicle checked as soon as possible to
    minimize engine damage.
    Note: Driving your vehicle without repair
    increases the chance of engine damage.
    Engine Coolant Temperature
    Management (If Equipped) WARNING
    To reduce the risk of crash and injury,
    be prepared that the vehicle speed
    may reduce and the vehicle may not
    be able to accelerate with full power until
    the coolant temperature reduces. If you tow a trailer with your vehicle, the
    engine may temporarily reach higher a
    temperature during severe operating
    conditions, for example ascending a long
    or steep grade in high ambient
    temperatures.
    At this time, you may notice the coolant
    temperature gauge moves toward the red
    zone and a message may appear in the
    information display.
    193
    F-650/750 (TBC) , enUSA, First Printing Maintenance 
    						
    							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 -

    System Refill Procedure
    The following procedure should be used
    when refilling the engine or secondary
    cooling systems after it has been drained
    or become extremely low:
    1. Before you remove the cap, turn the
    engine off and let it cool.
    2. When the engine is cool, wrap a thick cloth around the cap. Slowly turn cap
    counterclockwise until pressure begins
    to release.
    3. Step back while the pressure releases.
    4. When you are sure that all the pressure
    has been released, use the cloth to turn
    it counterclockwise and remove the
    cap.
    5. Slowly add prediluted engine coolant to the coolant reservoir until the
    coolant level is within the minimum
    and maximum range as listed on the
    reservoir.
    6. Reinstall the pressure relief cap.
    7. Start and run the engine at 2000 rpm for 2 minutes.
    8. Shut engine off, and remove the pressure relief cap as previously
    outlined.
    9. If required, add prediluted engine coolant to the coolant reservoir until
    the coolant level is within the minimum
    and maximum range as listed on the
    reservoir.
    10. Engine cooling system:
     Repeat
    Step 5 until the coolant level has
    stabilized (is no longer dropping after
    each step) and the upper radiator
    hose at the radiator is warm to the
    touch (indicating that the engine
    thermostat is open and coolant is

    12. Reinstall the pressure relief cap. Shut
    the engine off and let it cool.
    13. Check the coolant level in the reservoir before you drive your vehicle
    the next few times.
    14. If necessary, add prediluted engine coolant to the coolant reservoir until
    the coolant level is within the
    minimum and maximum range as
    listed on the reservoir. After any
    coolant has been added, check the
    coolant concentration.
    Recycled Coolant
    We do not recommend the use of recycled
    coolant as an approved recycling process
    is not yet available.
    Dispose of used engine coolant in an
    appropriate manner. Follow your
    community ’s regulations and standards
    for recycling and disposing of automotive
    fluids.
    Severe Climates
    If you drive in extremely cold climates:
    • It may be necessary to increase the
    coolant concentration above 50%.
    • A coolant concentration of 60%
    provides improved freeze point
    protection. Coolant concentrations
    above 60% decrease the overheat
    protection characteristics of the
    coolant and may cause engine
    damage. If you drive in extremely hot climates:
    •
    You can decrease the coolant
    concentration to 40%.
    • Coolant concentrations below 40%
    decrease the freeze and corrosion
    protection characteristics of the
    coolant and may cause engine
    damage.
    Vehicles driven year-round in non-extreme
    climates should use prediluted engine
    coolant for optimum cooling system and
    engine protection.
    Checking Coolant Corrosion
    Inhibitor Additive Strength
    At specific mileage intervals as listed in the
    scheduled maintenance information
    chapter, the coolant corrosion inhibitor
    additive should be checked. An information
    message may display in the optional
    information display at this time. The
    purpose of checking is to verify the correct
    engine coolant concentration (freeze point
    protection) and corrosion inhibitor additive
    level (strength) of the coolant for
    maximum engine performance and
    protection.
    Three products are available to confirm
    the life and health of the coolant, one tool,
    a test kit and a coolant inhibitor additive:
