Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the“H”and“C”). If it
enters the red section, the engine is
overheating. Stop the vehicle as
soon as safely possible, switch off
the engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
specificationschapter.
Never remove the coolant reservoir cap while the engine is
running or hot. Steam and scalding liquid from a hot cooling
system can burn you badly.
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate.
Engine oil pressure gauge
Indicates engine oil pressure. At
normal operating temperature, the
needle will be in the normal range
(the area between the“L”and“H”);
if the needle goes below the normal
range, stop the vehicle as soon as
safely possible and switch off the
engine immediately. Check the oil
level. Add oil if needed (refer to
Engine oilin theMaintenance
and specificationschapter). If the oil level is correct, have your vehicle
checked at your dealership or by a qualified technician.

•On some engines, theWait to
startlight should illuminate after
the engine starts. Allow the
engine to idle about three
minutes or until the engine
coolant temperature gauge begins to rise. Maintain idle speed until the
Wait to startlight cycles off to indicate the air intake heater has shut
off (approximately six minutes). Operating the engine at higher
speeds will reduce the effectiveness of the air inlet heater.
•Do not increase engine speed
until the oil pressure gauge
indicates normal pressure.
•Ensure engine oil pressure is
indicated on the gauge within 15
seconds after starting.
•Idle the engine for three to five
minutes before operating with a
full load.
•Try to limit engine idle to 10 minutes. Excessive idling reduces fuel
economy.
•When starting a cold engine, increase the engine speed (RPM) slowly
to make sure adequate lubrication is available to the bearings.
Restarting after running out of fuel
The fuel system may need to be purged of air, refer toRunning out of
fuelin theMaintenance and specificationschapter.
Cold weather starting
Perform the following to assure efficient starting in cold weather:
•Use the proper grade oil for your climate. Refer to your engine
operator’s manual for proper grade oil.
•Test the battery more frequently to assure ample power for starting.
•All electrical connections should be tight and in good condition to
prevent losses through loose or corroded connections.
Using the engine block heater (if equipped)
Use of an engine block heater is strongly recommended if you live in a
region where temperatures reach -23°C (-10°F) or below. For best
results, plug the heater in at least three hours before starting the vehicle.
The heater can be plugged in the night before starting the vehicle.WAIT

To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.
Operating the engine
Do not operate the engine at full throttle below peak torque engine
speed (RPM) for more than one minute at a time (peak torque RPM
varies from 1200-1500 RPM depending on engine rated speed).
Monitor the oil pressure and coolant
temperature gauges frequently.
If the gauges indicate any reading is
not in the normal operating range,
stop your vehicle as soon as possible,
shut the engine off and check the
appropriate fluid level. If an
overheating condition starts to occur,
release the throttle pressure or shift
the transmission into a lower gear, or
both, until the temperature returns to normal operating range.
Continuous operation with low
coolant temperature, below 60°C
(140°F) or high coolant temperature
100°C (212°F) can damage the
engine.
Most failures give some kind of early
warning. Look and listen for changes
in performance, sound or engine
appearance that can indicate service
or engine repair is needed. Some
changes to look and/or listen for:
•Engine misfires
•Loss of power
•Sudden changes in engine operating temperature or oil pressure
•Excessive smoke
•Fuel, oil or coolant leaks
•Vibration
•Increased oil or fuel consumption

Excessive full throttle operation below peak torque RPM will shorten
engine life to overhaul and can cause serious engine damage. Operation
of the engine below peak torque RPM can occur during gear shifting due
to difference of gear ratios.
Engine shutdown system (if equipped)
This system is designed to help prevent engine damage that could result
from operating the engine during a prolonged period of low engine oil
pressure, high engine coolant temperature or low coolant level. If any of
these conditions occur, a warning light will illuminate and a chime will
sound warning the operator that the engine will shutdown in 30 seconds.
This is to allow time for the operator to move the vehicle off the road. If
additional time is required, the engine can be restarted and run each
time for approximately 30 seconds.
Do not attempt to use this restarting feature to drive the vehicle, serious
engine damage could result.
Exhaust fumes
Never idle the engine in closed areas. Never sit in a parked or
stopped vehicle for any amount of time with engine running.
If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
In order to guard against fumes entering your vehicle, the exhaust
system and body ventilation system should be checked by a qualified
technician:
•Each time the vehicle is raised for service.
•Whenever a change in exhaust system noise is noted.
•Whenever the vehicle has been damaged by impact from another
vehicle, object or road obstruction.
In order to afford proper operation, all air inlet vents should be kept
clear of snow, leaves and other debris.
If you run the engine while stopped (idled) in an unconfined area, open
the windows at least 2.5 cm (one inch) and adjust the heating or air
conditioning to draw outside air into the vehicle as follows:
•If your vehicle has outside air control vents, open them fully.

PAINT CHIPS
Your dealer has touch-up paint and sprays to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jam) to
your dealer to ensure you get the correct color.
•Remove particles such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout before repairing paint chips.
•Always read the instructions before using the products.
ALUMINUM WHEELS AND COVERS
Aluminum wheel rims or covers are coated with a clearcoat paint finish.
In order to maintain their shine:
•Clean with Detail Wash (ZC-3–A), which is available from your dealer.
•Never apply any cleaning chemical to hot or warm wheel rims or
covers.
•Some automatic car washes may cause damage to the finish on your
wheel rims or covers. Chemical-strength cleaners, or cleaning
chemicals, in combination with brush agitation to remove brake dust
and dirt, could wear away the clearcoat finish over time.
•Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
•To remove tar and grease, use Ford Extra Strength Tar and Road Oil
Removal (B7A-19520–AA), available from your dealer.
ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean.
•Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
Cleaning
175

1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (an opaque plastic bottle).
Slowly turn cap counterclockwise (left) 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. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the“cold fill range”or the“cold full”level on the
reservoir. If you removed the radiator cap in an overflow system, fill the
radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. (Cap must be tightly
installed to prevent coolant loss.)
After any coolant has been added, check the coolant concentration see
Checking Engine Coolant section). If the concentration is not 50/50
(protection to–34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 liter (1.0 quart) of engine coolant per
month, have your dealer check the engine cooling system. Your cooling
system may have a leak. Operating an engine with a low level of coolant
can result in engine overheating and possible engine damage.
Replacing coolant
A coolant mixture of 50% coolant concentrate and 50% water is
recommended to maintain best overall performance. To avoid damaging
the engine and radiator, the coolant concentrate should not exceed 60%.
When refilling the coolant system either as part of the regular
maintenance (refer to the general maintenance information section), or
due to service performed, adhere to the following instructions:
1. Drain and flush the cooling system to remove dirt deposits, oil, rust
particles.
Note:
When filling the system with Motorcraft Premium Engine Coolant
(green-colored) or equivalent meeting Ford specification ESE-M97B44–A, a
supplemental coolant additive is required. Refer toAdding Coolantsection

excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
•Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
If you must replace the fuel filler cap, replace it with a genuine
Ford or Motorcraft part. The customer warranty may be void for
any damage to the fuel tank or fuel system if a genuine Ford or
Motorcraft fuel filler cap is not used.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel system to work improperly in a collision, which may result in
possible personal injury.
Choosing the right fuel
At operating temperatures below 0°C (32°F), use a blend of No. 1D and
No. 2D Diesel fuels, also known as winterized No. 2D.
Do not use diesel fuel blended with waste oil in engines equipped with a
catalytic converter-muffler. Blending waste oil in with the fuel will plug
the catalytic converter-muffler, resulting in a significant loss of engine
power. Your emissions warranty will be voided if blending waste oil with
diesel fuel is practiced.
Use low sulfur (less than 0.05% by weight) fuel as required by the EPA
for emission compliance.
Do not mix diesel fuel with gasoline, gasohol or alcohol. This
could cause an explosion resulting in personal injury.
Do not use starting fluid such as ether or gasoline. Such fluids
can cause immediate explosive damage to the engine and
possible personal injury.
Maintenance and Specifications

An inflated tire and rim can be very dangerous if improperly
used, serviced or maintained. To avoid serious injury, never
attempt to re-inflate a tire which has been run flat or seriously
under-inflated without first removing the tire from the wheel assembly
for inspection. Do not attempt to add air to tires or replace tires or
wheels without first taking precautions to protect persons and
property.
Refer to the Ford Service Manual or the regulations of the Occupational
Safety and Health Administration (OSHA) for appropriate procedures
and cautions.
Tire inflation pressure must not exceed the recommendations of
the axle, tire and/or wheel rim manufacturer for the specific
load, speed and application. The inflation pressures on the tire sidewall
do not take the wheel rim capabilities into consideration.
Never use a rim of different manufacture or any different size or
type than original rims.
Try to replace tires in pairs on the same axle shaft. Tires larger or
smaller than originally installed may affect the accuracy of the
speedometer. Consult your dealer about the need to change the switch
setting on the back of the speedometer.
Front wheel alignment
If abnormal tire wear or ride and handling characteristics such as vehicle
lead or wander are experienced with properly inflated tires, the front
end alignment should be checked.
Wheel bearing care
Front and rear wheel bearings are adjustable to correct for bearing and
spindle wear. Long bearing life depends upon proper adjustment and
correct lubrication. If bearings are adjusted too tightly (preloaded) they
will overheat and wear rapidly. Loose adjustment will cause pounding
and will contribute to uneven tire wear, steering difficulties and
inefficient brake operation.
Refer to the Ford Service Manual applicable to your vehicle for proper
tightening procedures and torque specifications.
Periodically check the oil level on oil filled front bearing hubs. If
necessary, add oil through the filler plug so the oil level is between the
Maintenance and Specifications

ADD and FULL marks indicated on the hub. Do not overfill. Overfilling
can result in oil on brake linings.
Refer to your general maintenance information section for fluid level
checks and change intervals for the front hubs.
Your front hubs may be filled with an optional synthetic fluid which
allows use of the extended service intervals. A green colored filler plug
identifies use of the synthetic fluid.
