2003 FORD F650 check engine

The push button shifter has a R
(Reverse), N (Neutral) and D
(Drive) selections as well as a
MODE button, up arrow (for
upshifts) and a down arrow
(downshift) and a digital display.
When a range button is pressed, a
tone will sound, the SELECT
indicator displays a chosen
operation (if the electronic control
unit determines the shift is
acceptable) and the transmission
will shift to the starting range. In D
(Drive), selection of a specific gear
can be accomplished by pressing the
up or down arrow button. If the
CHECK TRANS light (located on the instrument panel) is illuminated,
the shifter control pad may be disabled, tones will not be heard, shifts
may not occur and directional shift changes will not be able to be
performed.
The MODE button may be used to
activate a second shift schedule
(this is typically programmed for
Economywhich will enable the
transmission to shift at a lower RPM
to conserve fuel).
These transmissions incorporate a hold feature to prohibit upshifting
above the gear selected during normal driving. During downhill
operation, the transmission may upshift from the selected gear if the
electronic control unit detects the possibility of engine damage from
exceeding the governed engine speed.

Ratio extender use
Low End
A two-speed axle can be used as a ratio-extender when split shifting is
not necessary. For low end use, just shift the axle into the LO to start
out, and shift to HI when the extra torque is no longer needed.

DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine’s air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims (for cars).
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage. Have the fluid checked and, if
water is found, replace the fluid.

JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which burns skin, eyes, and
clothing.
Preparing your vehicle
Also see the label on the battery.
1. Use only a 12–volt supply to start your vehicle. If you connect your
battery to a 24–volt power supply you can damage your starter, ignition
system and other electrical components. Do not attach the jumper cables
to the glow plug relay as this could severely damage the glow plugs,
injector driver module and PCM.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the disabled vehicle making sure
theydo nottouch. Set the parking brake on both vehicles and stay clear
of the engine cooling fan and other moving parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure the vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
Roadside Emergencies
162

OPENING THE HOOD
The hood and fenders are held in position by a latch located on each
fender.
The parking brake must be fully set before opening the hood or
possible personal injury may occur.
If you must leave the engine running while checking under the
hood, do not allow any loose clothing, jewelry, hair or other
items to get near moving engine components or possible personal
injury may occur.
To open the hood:
1. Set the parking brake, shift into N (Neutral) (automatic transmission)
or 1 (First) (manual transmission) and turn the engine off.
2. Lift upward on the bottom of
each latch.
3. Pull the bottom of each latch
away from the fender.

WINDSHIELD WASHER FLUID
Checking and adding washer fluid
Inspect the solution level in the
washer reservoir when insufficient
solution is sprayed.
Use 3.8L (4.0 quarts) of
Ultra—Clear Windshield Washer
Concentrate or a washer fluid that
meets the Ford specification listed.
Refer toLubricant specifications
in this chapter.
State or local regulations on volatile
organic compounds may restrict the use of methanol, a common
windshield washer antifreeze additive. Washer fluids containing
non-methanol antifreeze agents should be used only if they provide cold
weather protection without damaging the vehicle’s paint finish, wiper
blades or washer system.
Do not put engine coolant or antifreeze in the washer fluid
reservoir. Engine coolant or antifreeze can severely reduce
visibility if sprayed on the windshield.
ENGINE OIL
Checking engine oil level—Cummins B and Caterpillar 3126 B
engines
Refer to the appropriate engine operator’s manual for information on the
engine oil.
Checking engine oil level—7.3L Power Stroke engine
Refer to the general maintenance information section for the appropriate
intervals for checking the engine oil.
Check the engine oil level consistently and accurately. The following
procedure is recommended:
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. Park the vehicle on level ground.
Maintenance and Specifications
180

Battery posts, terminals and related accessories contain lead and
lead compounds. Wash hands after handling.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the general maintenance information section.
The coolant concentration should be maintained at 50/50 coolant and
water, which equates to a freeze point of -36°C (-34°F). Coolant
concentration testing is possible with a hydrometer or antifreeze tester
(such as the Rotunda Battery and Antifreeze Tester, 014–R1060). The
level of coolant should be maintained at the“cold full”of“cold fill range”
level in the coolant reservoir. If the level falls below, add coolant per the
instructions in theAdding Engine Coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50–50 mixture of coolant and water provides the following:
•freeze protection down to -36°C (-34°F).
•boiling protection up to 129°C (265°F).
•protection against rust and other forms of corrosion.
•enables calibrated guages to work properly.
When the engine is cold, check the level of the engine coolant in the
reservoir.
When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the“cold fill level”or within the“cold
fill range”as listed on the engine coolant reservoir (depending upon
application).
Maintenance and Specifications
186

•Refer to the general maintenance information section for service
interval schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Vehicles with diesel engines typically are used to carry heavy loads and
accumulate mileage rapidly. These two factors cause the additives in the
coolant to“wear out”in a shorter time. Ford recommends an interim
service interval performed at 12 months or 24 000 km (15 000 miles),
whichever occurs first. Add 237–295 ml (8–10 oz.) of supplemental
coolant additive FW-16 to the cooling system. For vehicles with extensive
idling time, add 237–295 ml (8–10 oz.) of coolant additive FW-16 after
every 500 hours of operation. (see general maintenance information
section)
Adding engine coolant—7.3L Power Stroke
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool, until the appropriate fill level is obtained.
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, you can be burned if you spill coolant on hot engine parts.
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.
The cooling system in your vehicle is filled with either green-colored
Motorcraft Premium Engine Coolant meeting Ford specification
ESE-M97B44–A or yellow-colored Motorcraft Premium Gold Engine
Coolant meeting Ford Specification WSS-M97B51–A1. To determine your
vehicle’s coolant type (color), check your coolant reservoir.
•Add Motorcraft Premium Engine Coolant (green-colored),
VC-4–A (U.S.) or CXC-10 (Canada) or Motorcraft Premium
Maintenance and Specifications
187

Gold Engine Coolant (yellow-colored), VC-7–A (VC-7–Bin
Oregon), depending on the type of coolant originally equipped
in your vehicle.If you are unsure which type of coolant your vehicle
requires, check your coolant reservoir or contact your local dealer.
Note:Use of Motorcraft Cooling System Stop Leak Pellets, VC-6,
darkens the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.
•Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Speciality Orange Engine Coolant, VC-2 (US) or
CXC-209 (Canada), meeting Ford specification WSS-M97B44–D
with the factory-filled coolant.Mixing Motorcraft Speciality Orange
Engine Coolant or any orange-colored extended life product with your
factory filled coolant can result in degraded corrosion protection.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
•Do not use alcohol, methanol or brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).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 engine
coolant.
•Do not mix with recycled coolant unless from a Ford-approved
recycling process (seeUse of Recycled Engine Coolantsection).
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 the proper mixture of coolant and
water to the“cold full”level. For all other 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 of a vehicle with an overflow
system, follow these steps to add engine coolant.
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 the cap is loosened slightly.
