engine FORD EXPLORER 1997 2.G Repair Manual

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.
Calculating fuel economy
To accurately calculate your
vehicle's fuel economy:
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
Total miles traveled4Total
gallons used
Keep a record for at least one
month. This will provide an
accurate estimate of the vehicle's
fuel economy.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with

components and a catalytic
converter which will enable your
vehicle to comply with applicable
exhaust emission standards. To
make sure that the catalytic
converter and other emission
control components continue to
work properly:
²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition
while your vehicle is moving,
especially at high speeds.
²Have the services listed in your
ªService Guideº performed
according to the specified
schedule.
The Scheduled Maintenance
Services listed in the ªService
Guideº are required because they
are considered essential to the life
and performance of your vehicle
and to its emissions system.
If other than Ford, Motorcraft or
Ford authorized parts are used for
maintenance replacements or for
service of components affecting
emission control such non-Ford
parts should be equivalent to
genuine Ford Motor Company
parts in performance and
durability.
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.
Maintenance and care
207

Watch for fluid leaks, strange
odors, smoke, loss of oil pressure,
the charging system warning light,
the ªService Engine Soonº light or
the temperature warning light.
These events could indicate that
the emission control system is not
working properly.
If you smell exhaust fumes
of any kind inside your
vehicle, have the dealer inspect
and fix your vehicle immediately.
Do not drive if you smell exhaust
fumes. These fumes are harmful
and could kill you.
Do not make any unauthorized
changes to your vehicle or engine.
By law, vehicle owners and anyone
who manufactures, repairs,
services, sells, leases, trades
vehicles, or supervises a fleet of
vehicles are not permitted to
intentionally remove an emission
control device or prevent it from
working. Information about your
vehicle's emission system is on the
Vehicle Emission Control
Information Decal located on or
near the engine. This decal
identifies engine displacement and
gives some tune up specifications.
Please consult your ªWarranty
Guideº for complete emission
warranty information.
Readiness for
inspection/maintenance 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 ªcheck
engine/service engine soonº light is
on, reference the applicable light
description in theWarning Lights
and Gaugessection of your
owners guide. Your vehicle may
not pass the I/M test with the
ªcheck engine/service engine soonº
light on.
If the vehicle's powertrain system
or its battery has just been
serviced, the OBD-II system is
reset to a ªnot ready for I/M testº
condition. To ready the OBD-II
system for I/M testing, a minimum
of 30 minutes of city and highway
driving is necessary as described
below:
²First, at least ten minutes of
driving on an expressway or
highway.
²Next, at least twenty minutes
driving in stop and go, city type
traffic with at least four idle
periods.
Allow the vehicle to sit for at least
8 hours without starting the
engine. Then, start the engine and
complete the above driving cycle.
The engine must warm up to it's
normal operating temperature.
Once started, do not turn off the
engine until the above driving
cycle is complete.
Maintenance and care
209

any bugs and tar before waxing
vehicle. Use cleaning fluid or
alcohol with a clean cloth to
remove. Use tar remover to
remove any tar spots.
Repairing paint chips
Minor scratches or paint damage
from road debris may be repaired
with touch-up paint, paint repair
foil or aerosol paint spray from the
Ford accessory line. Observe the
application instructions on the
products.
Remove particles such as bird
droppings, tree sap, insect
remains, tar spots, road salt and
industrial fallout immediately.
Cleaning the wheels
Wash the wheels with the same
detergent you use to clean the
body of your vehicle. Do not use
acid-based wheel cleaners, steel
wool, fuel or strong detergents.
Never use abrasives that will
damage the finish of special wheel
surfaces. Use a tar remover to
remove grease and tar.
Cleaning the engine
Engines are more efficient when
they are clean because grease and
dirt buildup act as insulators and
keep the engine warmer than
normal. Follow these guidelines to
clean your engine:
²Take care when using a power
washer to clean the engine. The

high pressure fluid could
penetrate the sealed parts and
cause damage.
²Do not spray with cold water to
avoid cracking the engine block.
²Cover the highlighted areas to
prevent water damage when
cleaning the engine.
Maintenance and care
217

²Never wash or rinse the engine
while it is running; water in the
running engine may cause
internal damage.
Cleaning plastic exterior parts
Use a vinyl cleaner for routine
cleaning of plastic. Clean with a tar
remover if necessary. Do not clean
plastic parts with thinners,
solvents or petroleum-based
cleaners.
Cleaning the exterior lamps
Wash the exterior lamps with the
same detergent you used to wash
the exterior of your vehicle. Use
glass cleaner or tar remover if
necessary.
To avoid scratching the lamps, do
not use a dry paper towel,
chemical solvents or abrasive
cleaners to clean the lamps.
Cleaning the wiper blades
If the wiper blades do not wipe
properly, clean both the windshield
and wiper blades using undiluted
