Optional instrument cluster gauges
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 to

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 toEngine oilin the
Maintenance and specificationschapter). If the oil
level is correct, have your vehicle checked at your
dealership or by a qualified technician.
Battery voltage gauge
Indicates battery
voltage. If the pointer
moves and stays
outside the normal
operating range, have the vehicle’s electrical system
checked as soon as possible.
Fuel gauge
Displays approximately
how much fuel is in the
fuel tank. The fuel
gauge may vary slightly
when the vehicle is in motion or on a grade.

3. If the temperature is below -12°C (10°F) and
the engine does not start in 15 seconds on the first
try, turn the key OFF and wait 10 seconds and try
again. If the engine does not start in two attempts,
press the accelerator pedal all the way to floor and
hold. Turn the key to START position.
4. When the engine starts, release the key, then
release the accelerator pedal gradually as the engine
speeds up.
5. After idling for a few seconds, apply the brake,
shift into gear and drive.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant,
which improves starting, warms up the engine faster
and allows the heater-defroster system to respond
quickly. 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. Using the heater
for longer than three hours will not harm the engine,
so the heater can be plugged in the night before
starting the vehicle.
To prevent electrical shock, do not use your
heater with ungrounded electrical systems
or two-pronged (cheater) adapters.
Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is
present in exhaust fumes. Take precautions to avoid
its dangerous effects.
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.

WINDSHIELD WASHER FLUID
Check the washer fluid
whenever you stop for
fuel. The reservoir is
highlighted with a
symbol.
Add fluid to fill the
reservoir if the level is
low. In very cold
weather, do not fill the
reservoir completely.
Only use a washer fluid that meets Ford
specification ESR-M17P5–A . Refer toLubricant
specificationsin 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.
Note:Do not put washer fluid in the engine coolant
reservoir. Washer fluid placed in the cooling system
may harm engine and cooling system components.
ENGINE OIL
Checking the engine oil
Refer to the scheduled maintenance guide for the
appropriate intervals for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait 5 to 10 minutes for
the oil to drain into the oil pan.
3. Set the parking brake and ensure the gearshift is
securely latched in P (Park) (automatic
transmissions) or 1 (First) (manual transmissions).
4. Open the hood. Protect yourself from engine heat.

ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should
be checked at the mileage intervals in the scheduled
maintenance guide. 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.A50–50 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 gages to function properly
•3.8L OHV V6 engine

•4.6L SOHC V8
engine
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”as listed on the engine coolant reservoir.
•Refer to the scheduled maintenance guide 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 to
Adding 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.
Adding engine coolant
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.
Maintenance and Specifications
207

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 Gold
Engine Coolant (yellow-colored), VC-7–A
(VC-7–B in 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–Dwiththe
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
