2005 FORD SUPER DUTY oil temperature

The FCM/HFCM should be drained
at regular intervals or when the
WATER IN FUEL light illuminates in
the instrument cluster.
The fuel injectors are located in the center of the combustion chambers
in the cylinder head between the rocker arm assemblies. The glow plug
system and fuel injection system are controlled through the Powertrain
Control Module (PCM) and Fuel Injection Control Module (FICM).
Fuel is drawn from the fuel tank by a frame-mounted electric fuel pump.
The fuel pump provides pressurized fuel to the engine and is
electronically controlled by the fuel pump PCM relay. The fuel pump
contains a pressure relief valve for overpressure protection in the event
of restricted flow.
Lubrication system
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. Extended oil change
intervals can negatively affect engine performance, fuel economy and
engine life. Refer to the engine oil specification chart located under
Engine oil specificationsin theMaintenance and Specifcations
section of this supplement.
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 cooling system contains an engine oil cooler which is mounted in the
center valley of the engine. The cooler’s function is to regulate engine oil
temperature.
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.
On F-Super Duty vehicles equipped with a manual transmission,
refer toManual transmission shift speedsin theDrivingsection of
yourOwner’s Guidefor maximum vehicle speed in various gears. Do not
exceed 3,600 rpm. Maximum engine governed speed is 4,000 rpm
depending on engine load. 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.

STARTING THE ENGINE
Read all starting instructions carefully before you start your vehicle.
For temperatures below 32°F(0°C), the use of the correct grade engine
oil is essential for proper operation.
If your vehicle is equipped with a manual transmission,make sure
the parking brake is set fully before you turn the key. Depress the clutch
pedal and place the gearshift in the neutral position. The clutch must be
fully depressed in order to operate the starter. Do not press the
accelerator during starting.
If your vehicle is equipped with an automatic transmission,ensure
the gearshift lever is in P (Park) and the parking brake is set before you
turn the key. Do not press the accelerator during starting.
Cold weather starting
When operating in cold weather, use a minimum of 45 Cetane Diesel fuel
or use Cetane Index improvers from a reputable manufacturer.
Do not crank the engine for more than 30 seconds as starter damage
may occur. If the engine fails to start, turn the key to 3 (OFF) and wait
30 seconds before trying again.
Do not use starting fluid, such as ether, in the air intake system
(see air cleaner decal). Such fluid could cause immediate
explosive damage to the engine and possible personal injury.
Note:Do not add gasoline, gasohol or alcohol to diesel fuel. This
practice creates a serious fire hazard and causes engine performance
problems.
1. Turn the key to 4 (ON) without
turning the key to 5 (START).Do
not start the engineuntil the
glow-plug pre-heat indicator
turns off.

2. When the glow plug pre-heat
indicator turns off, turn the key to 5
(START), then release the key as
soon as the engine starts. The glow
plugs will continue to be activated for two minutes after the glow plug
pre-heat indicator
has turned off. If the engine is not started
before the glow plug activation time ends, the glow plugs will need to be
reset by turning the key to 3 (OFF).
3. After the engine starts, allow it to idle for about 15 seconds. Do not
increase engine speed until the oil pressure gauge indicates normal
pressure.
STOPPING THE ENGINE
Turn the ignition to 3 (OFF). To prolong engine life (after extended high
speed or maximum GVW operation), it is recommended that a hot engine
be allowed to operate at low idle for about 7–10 minutes which would
allow sufficient time for 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 Specificationssection of this supplement.
At temperatures below 20°F(–7°C), Number 2–D diesel fuel may thicken
enough to clog the fuel filter. Your vehicle is equipped with either an
FCM (E-Series) or an HFCM (F-Super Duty and Excursion) which acts
as a fuel filter/heater/water separator to keep the wax melted which will
help prevent fuel filter clogging. However, if the engine starts but stalls
after a short time and will not restart, the fuel filter(s) may be clogged.
For best results in cold weather, use Number 1–D diesel fuel or
“winterized”Number 2–D diesel fuel which has an additive to minimize
wax formation.
Your vehicle is also equipped with a bypass relief valve, located on the
fuel control module, which provides fuel flow to the engine if the fuel
pickup should become plugged by ice or wax. To allow this bypass valve
to function and avoid engine fuel starvation, it is recommended that,
during cold weather operation 32°F(0°C) or below, the fuel level in your
tank should not be allowed to drop below
1⁄4full. This will help prevent
air from entering the fuel system and stalling the engine.
In cold weather below 32°F (0°C) your diesel engine will slowly increase
to a higher idle speed if left idling in P (Park). As the engine warms-up,

SCHEDULED MAINTENANCE
The scheduled maintenance services in theGeneral Owner’s
Informationsection of this supplement are required because they are
considered essential to the life and performance of your vehicle.
Use only recommended fuel, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraft parts are designed and
built for best performance in your vehicle.
FUEL REQUIREMENTS
Choosing the right fuel
The engine is designed to use low sulfur number 1–Dor2–D Diesel fuel
only. At temperatures below -7°C (20°F), number 1–D or winter blend
number 2–D fuel is recommended. (SeeCold weather operationin the
Drivingchapter of this supplement.) Diesel fuel containing no more
than 5% of biodiesel may be used. Biodiesel fuel is a product derived
from renewable fuel sources such as vegatable oil, animal fat and cooking
oil.
Do not use home heating oil or any diesel fuel not intended for
highway use. Red dye is used to identify fuels intended for
agricultural and non-highway use. Damage to the fuel injection
system, engine and exhaust catalyst can occur if an improper fuel
is used. Do not add gasoline, gasohol or alcohol to diesel fuel.
This practice creates a serious fire hazard and engine
performance problems.
Fuel quality
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel that meets the ASTM D
Maintenance and Specifications

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 (from Ford Part No. FD–4604)
into the fuel filter housing.
2. Tighten cap onto fuel filter housing slowly, allowing fuel to soak into
the fuel filter element. Tighten cap until it contacts the housing.
After replacing the fuel filter, the engine will purge the trapped
air as it runs. The engine may run roughly and smoke until the air
is completely eliminated.
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 assure 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.
5. Read oil level on both sides of dipstick and use highest level (reading)
for the actual engine oil level.
6. Maintain the oil level between ADD and OPERATING RANGE on the
dipstick by adding oil as required. The distance from ADD to
OPERATING RANGE on the dipstick represents 1.9L (2 quarts). Do not
overfill. If the oil level exceeds OPERATING RANGE, oil consumption
may result.
Maintenance and Specifications

Engine oil specifications
To help achieve proper engine performance and durability, it is important
that only engine lubricating oils of the proper quality are used in your
diesel engine and that the engine oil is changedno laterthan the
recommended interval. Diesel engines require specially formulated oil to
resist contamination. Proper quality oils also provide maximum efficiency
of the crankcase ventilating system which reduces air pollution.
For normal or severe service, use Motorcraft oil or an equivalent oil
conforming to Ford Specification WSS-M2C171–D or API Service
categories CI-4, CI-4/SL or DHD-1. If CI-4 oil is not available, CH-4 is
acceptable..
Engine oils with improved fuel economy properties (energy conserving)
are currently available. If you use an energy conserving oil, be sure it
meets the recommended Ford Specification,APIservice categories and
SAE viscosity grades listed in the Lubricant and Maintenance Materials
Specifications chart. Some energy conserving oilsdo notmeet the
requirements necessary for your diesel engine.
* Heavy duty trailer towing with ambient temperatures above 10°C
(50°F) requires 15W-40 engine oil.
The use of correct oil viscosities for diesel engines is important for
satisfactory operation. Determine which oil viscosity best suits the
temperature range you expect to encounter for the next service interval.

A symbol has been developed by the
American Petroleum Institute (API)
to help you select the proper engine
oil. It will be included on the oil
container you purchase. The top
section of the symbol shows the oil
performance by the API designation.
This should match the owner guide recommendation. The center section
will show the SAE viscosity grade. The lower section will state energy
conserving if the oil has proven fuel saving capabilities.
Changing engine oil and filter
Change your oil and filter according to theGeneral Owner’s
Informationsection of this supplement. Change more frequently if your
vehicle operation includes extended periods of idling or low-speed
operation, driving for a long time in cold temperatures or driving short
distances. See the following sectionEngine lubrication for severe
service operationfor all severe duty restrictions.
Use Ford Engine Oil Filter Part No. 3C3Z-6731–AA (FL–2016) or
equivalent. These filters protect your engine by filtering harmful,
abrasive or sludge particles. The FL–2016 filters particles significantly
smaller than most available“will-fit”filters.
To replace the filter,
1. Unscrew the oil filter cap and wait a few seconds for the oil to drain
through the built-in drain valve.Note:The filter should be changed
before reinstalling the oil pan drain plug.
2. Reinstall and tighten the oil filter cap.
Do not handle a hot oil filter with bare hands.
Continuous contact with USED motor oil has caused cancer in
laboratory mice. Protect your skin by washing with soap and
water.
Engine lubrication for severe service operation
