engine FORD F150 2008 11.G Service Manual

Starting the engine
1. Turn the key to 3 (ON) without
turning the key to 4 (START). If
there is difficulty in turning the key,
rotate the steering wheel until the
key turns freely.
2. Turn the key to 4 (START), then
release the key as soon as the
engine starts.
Note:If the engine does not start on the first try, turn the key to OFF,
wait 10 seconds and try again. If the engine still fails to start, press and
hold the accelerator to the floor and try again; this will allow the engine
to crank with the fuel shut off in case the engine is flooded with fuel.
If your vehicle has an automatic transmission, it will have a computer
assisted cranking system. This feature assists in starting the engine. If
the ignition key is turned to 4 (START) and then released when the
engine begins cranking, the engine may continue cranking for up to
10 seconds or until the vehicle starts.
Cold weather starting (flexible fuel vehicles only)
As the outside temperature approaches freezing, ethanol fuel distributors
should supply winter grade ethanol (same as with unleaded gasoline). If
summer grade ethanol is used in cold weather conditions, 0°F to 32°F
(-18°C to 0°C), you may experience increased cranking times, rough idle
or hesitation until the engine has warmed up. The starting characteristics
of all grades of E
85ethanol make it unsuitable for use when ambient
temperatures fall below 0°F (-18°C). Consult your fuel distributor for the
availability of winter grade ethanol.
You may experience a decrease in peak performance when the engine is
cold when operating on E
85ethanol.
Do not crank the engine for more than 30 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to OFF and
wait 30 seconds before trying again.
Do not use starting fluid such as ether in the air intake system. Such
fluid could cause immediate explosive damage to the engine and possible
personal injury.
If you should experience cold weather starting problems on E
85ethanol,
and neither an alternative brand of E
85ethanol nor an engine block

heater is available, the addition of unleaded gasoline to your tank will
improve cold starting performance. Your vehicle is designed to operate
on E
85ethanol alone, unleaded gasoline alone, or any mixture of the two.
SeeChoosing the right fuelin theMaintenance and Specifications
chapter for more information on ethanol.
If the engine fails to start using the preceding instructions
(flexible fuel vehicles only)
1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then
crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speeds up. If the engine still fails to start,
repeat Step 1.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least one inch (2.5 cm) or adjust the heating
or air conditioning to bring in fresh air.
ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt a/c electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-17°C).
For flexible fuel vehicles, if operating with E
85ethanol, an engine block
heater must be used if ambient temperature is below 0°F (-18°C).
SeeCold weather startingin theDrivingchapter for more information
on starting with ethanol.

Failure to follow engine block heater instructions could result in
property damage or physical injury.
To reduce the risk of electrical shock, do not use your heater
with ungrounded electrical systems or two-pronged (cheater)
adapters.
Prior to using the engine block heater, follow these recommendations for
proper and safe operation:
•For your safety, use an outdoor extension cord that is product
certified by Underwriter’s laboratory (UL ) or Canadian Standards
Association (CSA). Use only an extension cord that can be used
outdoors, in cold temperatures, and is clearly marked
Suitable for Use
with Outdoor Appliances.
Never use an indoor extension cord
outdoors; it could result in an electric shock or fire hazard.
•Use a 16 gauge outdoor extension cord, minimum.
•Use as short an extension cord as possible.
•Do not use multiple extension cords. Instead, use one extension cord
which is long enough to reach from the engine block heater cord to
the outlet without stretching.
•Make certain that the extension cord is in excellent condition (not
patched or spliced). Store your extension cord indoors at
temperatures above 32°F (0°C). Outdoor conditions can deteriorate
extension cords over a period of time.
•To reduce the risk of electrical shock, do not use your heater with
ungrounded electrical systems or two pronged (cheater) adapters.
Also ensure that the block heater, especially the cord, is in good
condition before use.
•Make sure that when in operation, the extension cord plug /engine
block heater cord plug connection is free and clear of water in order
to prevent possible shock or fire.
•Be sure that areas where the vehicle is parked are clean and clear of
all combustibles such as petroleum products, dust, rags, paper and
similar items.
•Be sure that the engine block heater, heater cord and extension cord
are solidly connected. A poor connection can cause the cord to
become very hot and may result in an electrical shock or fire. Be sure
to check for heat anywhere in the electrical hookup once the system
has been operating for approximately a half hour.

•Finally, have the engine block heater system checked during your fall
tune-up to be sure it’s in good working order.
How to use the engine block heater
Ensure the receptacle terminals are clean and dry prior to use. To clean
them, use a dry cloth.
Depending on the type of factory installed equipment, your engine block
heater system may consume anywhere between 400 watts or 1000 watts
of energy per hour. Your factory installed block heater system does not
have a thermostat; however, maximum temperature is attained after
approximately 3 hours of operation. Block heater operation longer than
3 hours will not improve system performance and will unnecessarily use
additional electricity.
Make sure system is unplugged and properly stowed before driving the
vehicle. While not in use, make sure the protective cover seals the
prongs of the engine block heater cord plug.
BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by an authorized dealer. If the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.

During Traction Control™ operation,
the traction control active light will
illuminate and the engine will not
“rev-up” when you push further on
the accelerator. This is normal
system behavior and should be no
reason for concern.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a Traction Control™
event is an indication that at least some of the tires have exceeded
their ability to grip the road; this may lead to an increased risk of loss
of vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
The Traction Control™ switch,
located on the center console, has
an indicator light that illuminates
when the system is off. The Traction
Control™ system will automatically
turn on every time the ignition is
turned off and on. The Traction
Control™ system should normally
be left on.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching the Traction Control™ system off. This may allow
excess wheel spin to “dig” the vehicle out and enable a successful
“rocking” maneuver. Remember to switch the Traction Control™ system
back on once the vehicle is no longer stuck.
If a system fault is detected, the traction control active light will
illuminate, the Traction Control™ button will not turn the system on or
off and your vehicle should be serviced by an authorized dealer.
STEERING
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering fluid level
(below the MIN mark on the reservoir).
2008 F-150(f12)
Owners Guide (post-2002-fmt)
USA(fus)
Driving

•Some noise is normal during operation. If the noise is excessive, check
for a low power steering fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by a low power
steering fluid level. Check for a low power steering fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering fluid reservoir above the MAX mark on
the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle. The axle may
exhibit a slight noise or vibration in tight turns with low vehicle speed.
This is normal behavior and indicates the axle is working.
PREPARING TO DRIVE
Utility vehicles have a significantly higher rollover rate than
other types of vehicles.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a seat belt.
Utility vehicles and trucks have larger tires and increased ground
clearance, giving the vehicle a higher center of gravity than a passenger
car.

If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your authorized dealer.
Understanding the gearshift positions of the 4–speed automatic
transmission
Your vehicle’s automatic transmission is equipped with a special shift
strategy that ensures maximum heater performance during cold weather
operation.
When ambient temperature is 23°F (–5°C) or below and the engine
coolant temperature is below 100°F (38°C), light throttle upshifts may be
slightly delayed. Once the engine coolant temperature reaches 160°F
(71°C) the normal shift strategy will resume. This is normal operation
and will not affect the function or the durability of the transmission.
If the normal shift strategy does not resume once the engine
coolant temperature reaches the normal operating temperature,
or if the downshifts and other throttle conditions do not function
normally, see your authorized dealer as soon as possible.
P (Park)
This position locks the transmission and prevents the rear wheels from
turning.
To put your vehicle in gear:
•Start the engine
•Depress the brake pedal
•Move the gearshift lever into the desired gear
•Release the parking brake.

•This position allows for all forward gears except overdrive.
•O/D OFF lamp is illuminated.
•Provides engine braking.
•Use when driving conditions cause excessive shifting from O/D to
other gears. Examples: city traffic, hilly terrain, heavy loads, trailer
towing and when engine braking is required.
•To return to O/D (Overdrive), press the transmission control switch.
The O/D OFF lamp will not be illuminated.
•O/D (Overdrive) is automatically returned each time the key is turned
off.
2 (Second)
This position allows for second gear only.
•Provides engine braking.
•Use to start-up on slippery roads.
•To return to D (Overdrive), move the gearshift lever into the
D (Overdrive) position.
•Selecting 2 (Second) at higher speeds will cause the transmission to
downshift to second gear at the appropriate vehicle speed.

1 (First)
•Provides maximum engine braking.
•Allows upshifts by moving gearshift lever.
•Will not downshift into 1 (First) at high speeds; allows for 1 (First)
when vehicle reaches slower speeds.
Forced downshifts
•Allowed in D (Overdrive) or Drive.
•Depress the accelerator to the floor.
•Allows transmission to select an appropriate gear.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
MANUAL TRANSMISSION OPERATION (IF EQUIPPED)
Using the clutch
The manual transmission has a starter interlock that prevents cranking
the engine unless the clutch pedal is fully depressed.
To start the vehicle:
1. Make sure the parking brake is fully set.
2. Press the clutch pedal to the floor, then put the gearshift lever in the
neutral position.
3. Start the engine.
4. Press the brake pedal and move the gearshift lever to the desired
gear; 1 (First) or R (Reverse).

5. Release the parking brake, then slowly release the clutch pedal while
slowly pressing on the accelerator.
During each shift, the clutch pedal must be fully depressed to the floor.
Make sure the floor mat is properly positioned so it doesn’t interfere with
the full extension of the clutch pedal.
Failure to fully depress the clutch pedal to the floor may cause
increased shift efforts, prematurely wear transmission
components or damage the transmission.
Do not drive with your foot resting on the clutch pedal or use the
clutch pedal to hold your vehicle at a standstill while waiting on a
hill. These actions will reduce the life of the clutch.
