2010 FORD SUPER DUTY coolant temperature

Lubrication system
Extended oil change intervals can negatively affect engine performance,
fuel economy and engine life. Refer to the engine oil specification chart
located underEngine oil specificationsin theMaintenance and
Specificationschapter of this supplement.
On E-Series vehicles (6.0L engine),it is important to change the
engine oil at the recommended service intervals because oil viscosity is
important in maintaining the oil pressure required to actuate the fuel
injectors.
On F-Super Duty vehicles (6.4L engine),it is important to change
the engine oil at the recommended service intervals to maintain oil
viscosity with the addition of the diesel particulate filter (DPF).
Fast start glow plug system
The glow plug system consists of:
•eight glow plugs
•the glow plug control module (GPCM)
•engine oil temperature (EOT) sensor
•barometric pressure (BARO) sensor
The glow plug system is
electronically controlled by the
PCM. The GPCM energizes the glow
plugs immediately after the ignition
is placed in the ON position, then determines how long the glow plugs
will be on according to the EOT and BARO sensors. The required time
for the glow plugs to be energized decreases as the engine oil
temperature and barometric pressure increase.
Engine cooling system
The engine cooling system contains an engine oil cooler and an Exhaust
Gas Recirculation (EGR) cooler. The oil cooler’s function is to regulate
engine oil temperature. The EGR cooler function is to cool exhaust gases
before they are circulated back through the engine to reduce emissions.
Vehicles with diesel engines typically are used to carry heavy loads and
accumulate mileage rapidly. These two factors may cause the additives in
the coolant to “wear out” in a shorter time. Refer to the Special
Operating Conditions section for more information about coolant
additives and coolant change intervals. Operating the engine with
insufficient coolant and/or coolant additive can cause severe engine
damage.

To determine if a coolant additive recharge is required, check the nitrite
strength of the coolant using the coolant nitrate test strip kit (Acustrip
3-way Antifreeze Test Strip). If the nitrite strength is above 800 ppm no
action is required. If the nitrite strength is between 800 ppm to 300 ppm
add 32 fl. oz. (946 ml) of engine coolant additive, Motorcraft VC-8 or
equivalent. If the nitrite strength is below 300 ppm, flush & refill the
cooling system.
Fuel and turbocharger cooling system (F-Super Duty only)
The fuel and turbocharger cooling system contains a cooler which is
mounted on the turbo interstage U-tube on the left side of the engine.
The cooler’s function is to regulate engine fuel temperature and cool the
electronics that support the turbocharger. You may hear the auxiliary
coolant pump running up to 10 minutes after the ignition is turned off in
hot weather or if you are towing heavy loads. This is to control the
temperature of the turbocharger.
Engine governed speed
The engine governor is controlled by the PCM. The PCM controls fuel
input to limit maximum engine speed. It will not, however, prevent
engine overspeeding resulting from downshifting at high vehicle speed or
by descending steep grades at too high a vehicle speed for the selected
transmission gear.
If your vehicle is equipped with a manual transmission,refer to
Manual transmission shift speedsin theDrivingchapter of your
Owner’s Guidefor maximum vehicle shift speeds in various gears. Do
not exceed 4,000 rpm. Maximum engine governed speed is 3,700 rpm.
Excessive rpm can only be achieved by manually downshifting at too
high of a vehicle speed.
Operating the engine beyond the governed speed can cause
severe engine damage.
Speed control (F-Super Duty)
If vehicle speed goes outside a predetermined range from the set speed,
the RES (Resume) function will not reset vehicle speed. Vehicle speed
will need to be reset with the SET +/- button after reaching desired
speed using accelerator pedal.

ENGINE IDLE SHUTDOWN (IF EQUIPPED)
Your vehicle may be equipped with an engine idle shutdown system. This
system will automatically shut down your engine when it has been idling
in P (Park) or N (Neutral) for five minutes (parking brake set) or
15 minutes (parking brake not set). When the engine idle shutdown
process has started:
•A chime will sound and the message center will displayENGINE
TURNS OFF IN XX30 seconds prior to shutdown and begins
counting down to zero.
•The timer can be reset by changing the position of the accelerator
pedal, brake pedal or the park brake within the final 30 seconds.
•When the timer reaches zero, the engine shuts down and the message
center will displayENGINE TURNED OFF.
•One minute after the engine has shut down, the electrical system will
simulate key off, even though the ignition is still in the on position,
initiating normal accessory delay period.
•The ignition must be moved to the off position to reset the system
before restarting the vehicle.
Note:The engine idle shutdown idle timer will not start if:
•The engine is operating in power take-off (PTO) mode.
•The engine coolant temperature is below 60°F (16°C).
•The exhaust emission control device (DPF) is regenerating.
STOPPING THE ENGINE
Turn the ignition to the OFF position.
On E-Series vehicles,to prolong engine life (after extended high speed
or maximum GVW operation), it is recommended that a hot engine be
idled for 7–10 minutes which will allow the turbocharged engine to cool
down.
On F-Super Duty vehicles,to prolong engine life (especially after
extended high speed, high ambient temperature, or high GVW/GCW
operation), it is recommended that a hot engine be idled for 3-5 minutes
which will allow the turbocharged engine to cool down.

COLD WEATHER OPERATION
Changing to a lighter grade engine oil also makes starting easier under
these conditions. Refer toEngine oil specificationsin theMaintenance
and Specificationschapter of this supplement.
Diesel fuel is adjusted seasonally for cold temperatures. Diesel fuel which
has not been properly formulated for the ambient conditions may form
wax crystals which can clog the fuel filter. At temperatures below 20°F
(–7°C), if the engine starts, stalls after a short time, and then will not
restart, the fuel filter(s) may be clogged. For best results in cold
weather, use a diesel fuel which has been formulated for the ambient
conditions. If you have been using biodiesel, you may need to use a fuel
with lower biodiesel content, try another brand, or discontinue using
biodiesel.
Your vehicle is equipped with either an FCM or HFCM which recirculates
fuel from the engine to help prevent fuel filter clogging. Your vehicle is
also equipped with a bypass relief valve, located in the fuel tank pick-up
boot, which provides fuel flow to the engine if the fuel pickup should
become plugged. To allow the bypass valve to function and avoid engine
fuel starvation during cold weather operation of 32°F (0°C) or below, it
is recommended that the fuel level in your tank should not be allowed to
drop below
14full. This will help prevent air from entering the fuel
system and stalling the engine.
In cold weather below 32°F (0°C), the engine will slowly increase to a
higher idle speed if left idling in P (Park). As the engine warms-up, the
engine sound level will decrease due to the activation of PCM-controlled
sound reduction features.
If your vehicle is operated in a heavy snow storm or blowing snow
conditions, the engine air induction may become partially clogged with
snow and/or ice. If this occurs, the engine may experience a significant
reduction in power output. At the earliest opportunity, clear all the snow
and/or ice away from inside the air filter assembly. Take the top off the
assembly, leaving the air filter in, and remove any snow or ice.
In order to operate the engine in temperatures of 32°F (0°C) or lower,
read the following instructions:
•Make sure that the batteries are of sufficient size and are fully
charged. Check other electrical components to make sure they are in
optimum condition.
•Use Motorcraft Premium Engine Coolant solution at the concentration
recommended to protect the engine against damage from freezing.
•Try to keep the fuel tank full as much as possible at the end of
operation to prevent condensation in the fuel system.

2. Remove and discard the old fuel filter element.
3. Carefully clean the mating surfaces.
Installation - both
The engine will not run properly if the fuel filter is not installed
in housing.
1. Install the new fuel filter and cap seal into the fuel filter housing.
Refer toMotorcraft part numberslater in this chapter for the fuel filter
part number.
2. Tighten cap onto fuel filter housing slowly, allowing fuel to soak into
the fuel filter element. Tighten cap until it contacts the housing.
Turn the ignition key to on for 30 seconds, then turn it to off. Do this a
total of six times in a row to purge any trapped air from the fuel system.
Replace the filter bowl O-ring with new seal (included in filter kit) every
time you service the filter.
After filter service, a no start or rough running engine may indicate that
air is entering the system through the filter bowl seal or drain. Make sure
the drain lever is pointing rearward and stowed against the HFCM case.
Using a fuel which has more than average impurities may require
the fuel filter to be replaced more frequently than the service
interval specifies.
ENGINE OIL
Checking the engine oil level
Because it is normal to add some oil between oil changes, check your
engine oil level each time you stop for fuel. To check the engine oil level
consistently and accurately, the following procedure is recommended:
1. Have engine at normal operating temperature (at least into the
NORMAL range on the engine coolant temperature gauge).
2. Park the vehicle on a level surface, then turn off the engine and open
the hood.
3. Allow at least20 minutesafter engine shutdown to ensure that the
oil contained in the upper parts of the engine has returned to the oil
pan.
4. Protecting yourself from engine heat, pull out the dipstick, wipe it
clean and reinsert fully.
