engine FORD EXPEDITION 1998 1.G Repair Manual

²To help reduce early nozzle shut
off and fuel spillage, park your
vehicle so the fuel filler door is
level.
²Avoid excessively fast fuel
dispensing rates (over 38 L
[10 gallons] per minute).
²If you spill fuel on the body of
your vehicle, clean it off
immediately. The fuel may dull
or soften the paint if it is not
washed off promptly.
²To replace the fuel cap, align
the tabs on the cap with the
notches on the fuel filler pipe.
Turn it clockwise until it stops.
²Push the fuel door closed.
If the check engine warning light
illuminates and remains illuminated
while the engine is started, the
fuel cap may not be properly
seated. Turn off the engine,
remove the fuel cap and replace it,
being sure to align the cap
properly.
If the cap is lost, replace it with an
authorized Motorcraft or equivalent
part.
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).
Maintenance and care
182

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.
Watch for fluid leaks, strange
odors, smoke, loss of oil pressure,
the charging system warning light,
the ªCheck Engineº 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
Maintenance and care
184

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 (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 ªcheck
engine/service engine soonº light is
on, reference the applicable light
description in theWarning Lights
and Chimessection 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:
Maintenance and care
185

²First, at least 10 minutes of
driving on an expressway or
highway.
²Next, at least 20 minutes driving
in stop and go, city type traffic
with at least four idle periods.
Allow the vehicle to sit for at least
eight hours without starting the
engine. Then, start the engine and
complete the above driving cycle.
The engine must warm up to its
normal operating temperature.
Once started, do not turn off the
engine until the above driving
cycle is complete.
EXTERIOR BULBS
Replacing exterior bulbs
Check the operation of the
following lamps frequently:
²headlamps
²foglamps
²high-mount brakelamp
²brakelamps
²parking lamps
²turn signals
²license plate lamp
²tail lamps
²back-up lamps
Do not remove lamp bulbs unless
they can be replaced immediately
with new ones. If a bulb is
removed for an extended period of
time, contaminants may enter the
lamp housings and affect lamp
performance.
Maintenance and care
186

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 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 with the same detergent as
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 keep the engine
warmer than normal. When
washing:
²Take care when using a power
washer to clean the engine. The
high pressure fluid could
penetrate the sealed parts and
cause damage.
Maintenance and care
195

²Do not spray with cold water to
avoid cracking the engine block
or other engine components.
²Cover the highlighted areas to
prevent water damage when
cleaning the engine.
²Never wash or rinse the engine
while it is running; water in the
running engine may cause
internal damage.
Cleaning plastic exterior parts
Use vinyl cleaner for routine
cleaning. Clean with a tar remover
if necessary. Do not clean plastic
parts with thinners, solvents or
petroleum-based cleaners.
Cleaning the exterior lamps
Wash with the same detergent as
the exterior of your vehicle. Use
glass cleaner or tar remover if
necessary.

1Your vehicle's rear axle is
equipped with synthetic rear axle
lubricant. Rear axles containing
synthetic lubricant are lubricated
for life. These lubricants are not to
be checked or changed unless a
leak is suspected, service required
or the axle has been submerged in
water. The axle lubricant should be
changed any time the axle has
been submerged in water. Add 118
ml (4 oz.) of additive friction
modifier C8AZ-19B546±A, Ford
specification EST-M2C118±A
whenever the fluid is changed.
Service refill capacities are
determined by filling the rear axle
