1998 FORD EXPLORER Owners Manual

EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control 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 ``Service Guide'' performed according
to the specified schedule.
The Scheduled Maintenance Services listed in the ``Service Guide'' 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 ``Check Engine'' 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
Maintenance and care
185

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 ``Warranty Guide'' 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 ``check engine/service
engine soon'' light is on, reference the applicable light description in the
Warning Lights and Chimessection of your owners guide. Your vehicle
may not pass the I/M test with the ``check engine/service engine soon''
light on.
If the vehicle's powertrain system or its battery has just been serviced,
the OBD-II system is reset to a ``not ready for I/M test'' 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 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.

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.
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.
If the bulb is accidentally touched, it should be cleaned with rubbing
alcohol before being used.
To remove the headlamp bulb:
1. Make sure headlamp switch is in OFF position, then open the hood. If
you are replacing the driver side headlamp, unclip the electronic module
on the right side of the battery and move it out of the way.
2. Locate the headlamp bulb through the hole in the upper radiator
support assembly.
3. Disconnect the electrical
connector from the bulb by pulling
the connector rearward.
4. Remove the bulb retaining ring by
rotating it counterclockwise (when
viewed from the rear) about an
eighth of a turn to free it from the
bulb socket, and by sliding the ring
off the plastic base. Keep the ring
because it will be used again to
retain the new bulb.
Maintenance and care
187

5. Remove the old bulb from its socket by gently pulling it straight back
out of the socket. Do not turn the bulb while removing it.
To install the new bulb:
1. With the flat side of the bulb's
plastic base facing upward, insert
the glass end of the bulb into the
socket. You may need to turn the
bulb left or right to line up the
grooves in the plastic base with the
tabs in the socket. When the
grooves are aligned, push the bulb
into the socket until the plastic base
contacts the rear of the socket.
2. Slip the bulb retaining ring over the plastic base until it contacts the
rear of the socket by rotating it clockwise until you feel a ``stop''.
3. Push the electrical connector into the rear of the plastic base until it
snaps, locking it into position.
4. Turn the headlamps on and make sure they work properly. If the
headlamp was correctly aligned before you changed the bulb, you should
not need to align it again.

AIMING THE HEADLAMPS
Your vehicle is equipped with a
Vehicle Headlamp Aim Device
(VHAD) on each headlamp. Each
headlamp may be properly aimed in
the vertical (up/down) and the
horizontal (left/right) directions
using your VHAD system. The
headlamps on your vehicle are
properly aimed at the assembly
plant, and vertical and horizontal
indicators of the VHAD system are
calibrated.
A bubble (vertical indicator) that is
not centered between the two red
lines does not necessarily indicate
out-of-aim headlamps. If your
vehicle is not positioned on a level surface, the slope will be included in
the vertical indication. Therefore, vertical and horizontal headlamp
adjustment should be performed only when the beam direction appears
to be incorrect.
You will need one 4 mm wrench or socket with ratchet to make the
adjustments.
The following procedure assumes that the factory set horizontal indicator
reference has not changed and the vehicle's front structure is in its
factory alignment condition. If the vehicle has been in an accident
requiring the front end of the vehicle to be repaired, the horizontal
indicator should be recalibrated by the servicing facility according to
instructions in the vehicle's Workshop Manual.

Horizontal aim adjustment
1. With the hood open, locate the
horizontal indicator and adjusting
screw. They are located below the
viewing hole at the rear of the
headlamp assembly.
2. Use a 4mm wrench or socket to
turn the horizontal adjusting screw
until the ``0'' mark on the yellow dial
lines up with the reference mark on
the marker (as shown) when viewed
directly from above.
Vertical aim adjustment
1. Park the vehicle on a level
surface.
2. With the hood open, locate the
bubble level and vertical adjustment
screw. The adjustment screw is
located on the outboard side of the
headlamp.

3. The ``UP'' and ``DN'' on the bubble
indicate the directional change (up
or down) of the vertical aim.
4.Usea4mmwrench or socket to
turn the vertical adjusting screw
clockwise or counterclockwise until
the bubble is centered over the ``0''
mark.
Repeat the above process to the other headlamp, if necessary.
CLEANING AND CARING FOR YOUR VEHICLE
Refer to the ``Customer Assistance Guide'' for a list of Ford-approved
cleaners, polishes and waxes.
Washing your vehicle
Wash your vehicle regularly with
cold or lukewarm water. Never use
strong detergents or soap. If your
vehicle is particularly dirty, use a
quality car wash detergent. Always
use a clean sponge, washing glove
or similar device and plenty of water
for best results. To avoid spots,
avoid washing when the hood is still
warm, immediately after or during
exposure to strong sunlight.
During winter months, it is especially important to wash the vehicle on a
regular basis. Large quantities of dirt and road salt are difficult to
remove and also cause damage to the vehicle. Remove any exterior
accessories, such as antennas, before entering a car wash.
After washing, apply the brakes several times to dry them.

Waxing your vehicle
Wax when water stops beading on the surface. This could be every three
or four months, depending on operating conditions.
Use only carnauba or synthetic-based waxes. Remove 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 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.
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.
