Freezing Protection
[MC12800(FM)04/96]
The factory-installed solution of Ford Premium
Cooling System Fluid and water will protect
your vehicle toS35ÊF (S37ÊC).Check the freeze
protection rating of the engine coolant at least
once a year, just before winter.
*
[MC12850(FM)04/96]
Add engine coolant only to the coolant
reservoir.If the coolant level is low, add to the
reservoir a 50/50 mixture of water and the type
of engine coolant that Ford specifies. You may
add water by itself only in an emergency, but
you should replace it with a 50/50 mixture as
soon as possible. Check the engine coolant again
the next few times you drive your vehicle.
*
[MC12900(FM)01/96]
Ford Premium Cooling System Fluid is an
optimized formula that will protect all metals
and rubber elastomers used in Ford engines for
four years or 50,000 miles (80,000 km). It is not
necessary and not recommended to use
supplemental coolant additives in your gasoline
powered vehicle. These additives may harm
your engine cooling system. Follow the
recommended service interval for changing your
engine coolant.
*
[MC12950(FM)01/96]
NOTE: When you change or add engine
coolant, it is important to maintain
your engine coolant concentration
between 40%(-11ÊF [-24ÊC]) and 60%
(-62ÊF [-52ÊC]),depending on your local
climate conditions. Below 40% you will
lose freeze protection and above 60%
your engine may overheat on a warm
day.

4. Let the engine coolant drain into a suitable
container. Disconnect the lower radiator hose
at the radiator connector and drain any
remaining engine coolant into a container.
*
[MC13850(FM)01/96]
5. Reconnect the lower radiator hose and close
the radiator drain cock.

Engine coolant refill procedure
*
[MC14000(FM)01/96]
After you have drained the engine cooling
system:
*
[MC14050(FM)01/96]
1. Fill the radiator with a 50/50 mixture of the
specified engine coolant concentrate and
water. Allow several minutes for trapped air
to escape (bubble out) and for engine coolant
to flow through the radiator.
*
[MC14100(FM)01/96]
2. Replace the radiator cap to its fully installed
position, then back off to the first stop. This
will prevent high pressure from building up
in the cooling system during this part of the
fill procedure.
*
[MC14150(FM)01/96]
3. Start and idle the engine until the thermostat
opens and the radiator upper hose becomes
warm.
*
[MC14200(FM)01/96]
4. Shut off the engine and allow the engine to
cool. Cover the radiator cap with a thick
cloth and cautiously remove it. Step back
while the pressure releases.
*
[MC14250(FM)01/96]
5. Finally, check the radiator and add more
engine coolant if needed, following the
procedures noted above. Reinstall the
radiator cap securely, when finished.
*
[MC14300(FM)01/96]
6. If more engine coolant is necessary, fill the
overflow reservoir to the appropriate level
marked on the bottle.

Automatic Transmission Fluid
[MC21360(F )05/96]
Your vehicle does not use up transmisison fluid.
However it is recommended that you check the
transmission fluid at least twice a year. If the
transmission is not working properly Ð for
instance, the transmission may slip or shift
slowly, or if you notice some sign of fluid
leakage Ð the fluid level should be checked.
[MC21450(F )05/96]
NOTE: For E4OD transmissions, there is no
30,000 mile (48,000 km) sheduled
transmission fluid change requirement.

Information About Tire Quality Grades
*
[MC27370(FM)01/96]
New vehicles are fitted with tires that have their
Tire Quality Grade (described below) molded
into the tire's sidewall. These Tire Quality
Grades are determined by standards that the
United States Department of Transportation has
set.
*
[MC27380(FM)01/96]
Tire Quality Grades apply to new pneumatic
tires for use on passenger cars. They do not
apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires
with nominal rim diameters of 10 to 12 inches or
limited production tires as defined in Title 49
Code of Federal Regulations Part 575.104(c)(2).
[MC27390(FM)03/96]
U.S. Department of Transportation Ð Tire
quality grades:The U.S. Department of
transportation requires Ford to give you the
following information about tire grades exactly
as the government has written it.
%*
[MC27410(FM)01/96]
Treadwear
*
[MC27420(FM)01/96]
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course. For example, a tire
graded 150 would wear one and one-half (1 1/2)
times as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.

[MC32250(FM)04/96]
Your vehicle was not designed to use fuel
containing manganese-based additives such as
MMT. Additionally, vehicles certified to
California emission standards (indicated on the

Information label) are designed to operate on
California reformulated gasolines. If California
reformulated gasoline is not available when you
refuel, your vehicle can be operated on
non-California fuels. However, even though your
engine will perform adequately on other
gasolines, the performance of the emission
control devices and systems may be adversely
affected. Repair of damage caused by using a
fuel that your vehicle was not designed for may
not be covered by your warranty.

Emission Control System
*
[MC38950(F )01/96]
Your vehicle is equipped with a catalytic
converter which enables your vehicle to comply
with applicable exhaust emission requirements.
*
[MC38975(FM)01/96]
RWARNING
Exhaust leaks may result in the entry of
harmful and potentially lethal fumes into
the passenger compartment. Under
extreme conditions excessive exhaust
temperatures could damage the fuel
system, the interior floor covering, or
other vehicle components, possibly
causing a fire.
*
[MC39000(F )01/96]
To make sure that the catalytic converter and the
other emission control parts continue to work
properly:
*
[MC39075(FM)01/96]
q
Avoid running out of fuel.
*
[MC39100(FM)01/96]
q
Do not turn off the ignition while your
vehicle is moving, especially at high speeds.
*
[MC39125(FM)02/96]
q
Have the services listed in theMaintenance
Schedulebooklet performed according to the
specified schedule. The scheduled
maintenance services are required because
they are considered essential to the life and
performance of your vehicle and to its
emissions system.
*
[MC39150(FM)01/96]
In general, maintenance, replacement, or service
of the emissions control devices or systems in
your new Ford Motor Company vehicle or
engine may be performed at your expense by
any automotive repair establishment or
individual using automotive parts equivalent to
those which your vehicle or engine was
originally equipped.

[MC39175(FM)01/96]
RWARNING
Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine
compartment and exhaust system, which
can start a fire.
*
[MC39200(F )01/96]
RWARNING
On vehicles without original equipment
floor covering or insulation, do not let
passengers ride in your truck in a manner
that allows contact between skin and the
metal floor.
*
[MC39225(FM)01/96]
If other than Ford or Motorcraft or Ford
authorized remanufactured parts are used for
maintenance, replacement, or for the service of
components affecting emissions control, the
owner should be assured that such parts are
warranted by their manufacturer to be
equivalent to genuine Ford Motor Company
parts in performance and durability. Please
consult your warranty information booklet for
complete warranty information.
*
[MC39250(F )01/96]
Watch for fluid leaks, strange odors, smoke, loss
of oil pressure, the charge warning light, the
check engine light, or the temperature warning
light. These sometimes indicate that the emission
system is not working properly.
*
[MC39275(FM)01/96]
Do not make any unauthorized changes to your
vehicle or engine. Changes that cause more
unburned fuel to reach the exhaust system can
increase the temperature of the engine or
exhaust system.
