1998 FORD EXPEDITION oil

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

Replacing headlamp bulbs
Handle a halogen
headlamp bulb carefully
and keep out of children's reach.
Grasp the bulb only by its plastic
base and do not touch the glass.
The oil from your hand could
cause the bulb to break the next
time the headlamps are
operated.
1. Make sure that the headlamp
control is in the OFF position.
2. Open the hood.
3. At the back of the headlamp,
pull clips rearward and up (about
ôº) to release the headlamp
assembly.
4. Slide headlamp assembly
forward and off of guide ribs to
expose the back of the bulb and
wiring connector.
5. Remove the electrical connector
from the bulb by grasping the wire
and pulling it rearward.
6. Remove bulb retainer ring by
turning it counterclockwise about
1¤4turn, then slide the ring off the
plastic base.
7. Without turning, carefully pull
bulb assembly out of headlamp
assembly.

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

Check the safety belt system
periodically to make sure there are
no nicks, wear or cuts. If your
vehicle has been involved in an
accident, refer to theSafety belt
maintenancesection in the
Seating and safety restraints
chapter.
Cleaning leather seats
For routine cleaning, wipe the
surface with a soft, damp cloth.
For more thorough cleaning, wipe
the surface with a leather and
vinyl cleaner or a mild soap.
The type of scrubbing pad is
very critical because the
common 3M ªScotch Briteº
green pad is too aggressive and
will damage the leather surface
²Spray a small amount of the
leather cleaner on the pad and
rub the area to be cleaned with
the pad using a circular motion.
Only clean 1/4 of the area at a
time. For heavily soiled areas,
spray the cleaner directly onto
the leather (two squirts should
be adequate) and rub with the
pad. Repeat if necessary.
²Use a soft, damp cloth to
remove the loosened dirt and
foam.
²Dry with a soft cloth.
Do not use household cleaners,
glass cleaner, alcohol solutions
or cleaner intended for vinyl,
rubber or plastics. These
