maintenance FORD E SERIES 1997 4.G Service Manual

Using snow tires and chains
Snow tires must be the
same size and grade as the
tires you currently have on your
vehicle.
The tires on your vehicle have
allÐweather treads to provide
traction in rain and snow. However,
in some climates, using snow tires
and chains may be necessary. Ford
offers tire cables as a Ford
approved accessory and
recommends use of these or their
equivalents. See your dealer or
qualified service technician for
more information on tire cables for
your vehicle. Follow these
guidelines when using snow tires
and chains:
²Install chains securely, verifying
that the chains do not touch any
wiring, brake lines or fuel lines.
²Install the chains on the rear
tires only.
²Drive cautiously. If you hear the
chains rub or bang against the
vehicle, stop and retighten
them. If this does not work,
remove the chains to prevent
vehicle damage.
²Avoid overloading your vehicle.
²Remove the tire chains when
they are no longer needed. Do
not use chains on dry roads.
²The suspension insulation and
bumpers will help prevent
vehicle damage. Do not remove

WHAT YOU SHOULD KNOW
ABOUT AUTOMOTIVE FUEL
Important safety precautions
Do not overfill the fuel
tank. The pressure in an
overfilled tank may cause
leakage and lead to fuel spray
and fire.
If you do not use the
proper fuel cap, the
pressure in the fuel tank can
damage the fuel system or cause
it to work improperly in a
collision.
The fuel system may be
under pressure. If the fuel
cap is venting vapor or if you
hear a hissing sound, wait until it
stops before completely
removing the cap.
Automotive fuels can
cause serious injury or
death if misused or mishandled.

Observe the following guidelines
when handling automotive fuel:
²Extinguish all smoking materials
and any open flames before
fueling your vehicle.
²Always turn off the vehicle
before fueling.
²Automotive fuels can be harmful
or fatal if swallowed. If fuel is
swallowed, call a physician
immediately, even if no
symptoms are immediately
apparent. The toxic affects of
fuel may not be visible for
hours.
²Fuels can also be harmful if
absorbed through the skin. If
fuel is splashed on the skin,
promptly remove contaminated
clothing and wash skin
thoroughly with soap and water.
²If fuel is splashed in the eyes,
remove contact lenses, flush
with water for 15 minutes and
seek medical attention.
²Be particularly careful if you are
taking ªAntabuseº or other
forms of disulfiram for the
treatment of alcoholism.
Breathing gasoline vapors or
skin contact could cause an
adverse reaction. Consult a
physician immediately.
Choosing the right fuel
Use only UNLEADED FUEL. The
use of leaded fuel is prohibited by
law and could damage your

vehicle. The damage may not be
covered by your warranty.
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
underhood Vehicle Emissions
Control 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.
Octane recommendations
Your vehicle is designed to use
regular gasoline with an (R+M)/2
octane rating of 87. We do not
recommend gasolines labeled as
ªregularº in high altitude areas that
are sold with octane ratings of 86
or even less.
Do not be concerned if your
vehicle sometimes knocks lightly.
However, if it knocks heavily under
most driving conditions on the
87
com_octane_recommendations.01
Maintenance and care
159

recommended octane fuel, see
your dealer or a qualified service
technician to prevent any engine
damage.
Fuel quality
If you are experiencing starting,
rough idle or hesitation problems
try a different brand of fuel. If the
condition persists, see your dealer
or a qualified service technician.
The American Automobile
Manufacturers Association (AAMA)
issued a gasoline specification to
provide information on high quality
fuels that optimize the
performance of your vehicle. We
recommend the use of gasolines
that meet the AAMA specification
if they are available.
It should not be necessary to add
any aftermarket products to your
fuel tank if you continue to use a
high-quality fuel.
Cleaner air
Ford approves the use of gasolines
to improve air quality, including
reformulated gasolines, that
contain oxygenates such as a
maximum of 10% ethanol or 15%
MTBE. There should be no more
than 5% methanol with cosolvents
and additives to protect the fuel
system.

1. Fill the tank completely and
record the initial odometer
reading.
2. Each time you fill the tank,
record the amount of fuel added
(in liters or gallons).
3. After at least three to five fuel
tank fill-ups, fill the fuel tank and
record the current mileage
reading.
4. Use one of the following
equations to calculate fuel
economy.
Liters used x 1004Total
kilometers traveled

gallons used
Keep a record for at least one
month. This will provide an
accurate estimate of the vehicle's
fuel economy.
WHAT YOU SHOULD KNOW
ABOUT THE EMISSION
CONTROL SYSTEM
Your vehicle is equipped with a
catalytic convertor which enables
your vehicle to comply with
applicable exhaust emission
requirements. For more
information on your vehicle's
emission control system, see the
Vehicle Emission Control
Information decal located on the
left side of the engine
compartment.
Follow these guidelines to ensure
proper emission system operation:

Maintenance and care
161

²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition
while the vehicle is in motion.
²Have regular maintenance
checks performed according to
the intervals in theService
Guide.
When servicing your vehicle, never
use a metal exhaust collector. A
metal collector may melt or deform
plastic parts.
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.
If you smell exhaust fumes
inside your vehicle, have
your dealer inspect your vehicle
immediately. Do not drive if you
smell exhaust fumes.
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.
If you notice one or more of the
following, the emissions system
may not be working properly. Have
your vehicle serviced as soon as
possible.
Maintenance and care

²Fluid leaks
²The
or service engine soon
lights illuminate in the
instrument cluster and remain
lit.
²Strange odors
²Engine runs more than five
seconds after shut-off or engine
misfires, surges, stalls or
backfires
²Loss of oil pressure
Important emission control
information
By law, anyone who manufacturers,
repairs, services, leases, trades
vehicles or supervises a fleet of
vehicles is not permitted to
intentionally remove an emission
control device or prevent it from
working. Do not make any
unauthorized changes to the
vehicle or engine. Changes that
cause more unburned fuel to reach
the exhaust system can increase
the temperature of the engine or
exhaust system.
When your vehicle is serviced,
never use a metal exhaust
collector. The use of a metal
collector may melt or deform
plastic parts.
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.

Preparing your vehicle for
inspection/maintenance (I/M)
testing
In some localities it may be a legal
requirement to pass an I/M test of
the on-board diagnostic (OBD) II
system. If your vehicle's powertrain
system or battery has just been
serviced, the OBD II system is
reset to a condition unready for
I/M testing. To ready the OBD II
system for I/M testing, the law
specifies that additional city and
highway driving is necessary to
complete the check of the OBD II
system.
The driving modes required to
reach the ready condition consist
of a minimum of 30 minutes of city
and highway driving:
²At least 20 minutes driving in
stop and go city-type traffic with
at least four idle periods.
²At least ten minutes of driving
on an expressway or highway.
Before completing the above
driving modes, the engine must be
warmed up and at operating
temperature. Once started, the
vehicle must not be turned off
during these modes.
