4. Remove the auxiliary foam filter from
the air filter housing.
5. To install, reverse the removal procedure. The housing cover can be
oscillated slightly left to right to assist
with installation as needed, until
positioned such that all three clips can
be re-engaged.
Air Filter Restriction Gauge The air filter restriction gauge is in the
upper housing of the air filter assembly. Check the air filter restriction gauge
whenever you open the hood to carry out
general engine maintenance or at least
every 7,500 mi (12,000 km). If you operate
your vehicle in extremely dusty conditions,
check the gauge at least every 500 mi
(800 km) or two weeks, whichever occurs
first. Change the air filter element when
the restriction gauge reads near the
change filter line and the gauge is yellow.
Allowing the restriction gauge to reach
maximum affects engine performance and
fuel economy.
Operating your vehicle in heavy snowfall
or extreme rain conditions may allow
excessive amounts of snow or water into
the air intake system. This could restrict air
flow and cause the engine to lose power
or shut down.
After installing a new air filter element, you
must reset the gauge by pressing the reset
button.
After operating your vehicle during heavy
snowfall or extreme rain, do the following:
• Snow: At the earliest opportunity, open
the hood and clear any snow and ice
from the air filter housing inlet and
reset the air filter restriction gauge.
• Extreme rain: The air filter element
dries out after approximately 15– 30
minutes of driving at highway speeds.
At the earliest opportunity, open the
hood and reset the air filter restriction
gauge.
Note: Do not remove the foam filter.

CHANGING THE ENGINE AIR
FILTER - 7.3L
WARNING: To reduce the risk of
vehicle damage and personal burn
injuries, do not start your engine with the
air cleaner removed and do not remove
it while the engine is running.
Note: Operating your vehicle in heavy
snowfall or extreme rain conditions may
allow excessive amounts of snow or water
into the air intake system. This could plug
or soak the air filter that could cause the
engine to lose power or shut down.
When replacing the air filter element, use
a Motorcraft® air filter element. See
Motorcraft Parts
(page 438).
Note: Failure to use the correct air filter
element may result in severe engine
damage. Resulting component damage
may not be covered by the vehicle Warranty.
Change the air filter element at the correct
interval. See
Scheduled Maintenance
(page 557). 1. Locate the mass air flow sensor
electrical connector on the air outlet
tube. Disconnect the mass air flow
sensor electrical connector. 2. Reposition the locking clip on the
connector, squeeze the connector and
pull it off of the air outlet tube. 3.
Clean the area from around the air tube
to the air cover connection to prevent
debris from entering the system. Next,
loosen the bolt on the air tube clamp
so the clamp is no longer snug to the
air tube. It is not necessary to
completely remove the clamp.
4. Pull the air tube off from the air cleaner
housing.

the slots.
9. Slip the air tube onto the air filter housing and tighten the air-tube clamp
bolt snugly. Do not over tighten
air-tube clamp bolt. 10. Reconnect the mass air flow sensor
electrical connector to the outlet
tube. Make sure the locking tab on
the connector is in the locked
position.

other headlamp.
7. Close the hood and turn off the lamps.
Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.
WASHER FLUID CHECK WARNING: If you operate your
vehicle in temperatures below 40°F
(5°C), use washer fluid with antifreeze
protection. Failure to use washer fluid
with antifreeze protection in cold
weather could result in impaired
windshield vision and increase the risk
of injury or accident.
Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See
Capacities and
Specifications (page 433).
State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle ’s paint finish, wiper blades or
washer system.
FUEL FILTER - 6.2L
Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed. CHECKING THE WIPER
BLADES
Run the tip of your fingers over the edge of
the blade to check for roughness.
Clean the wiper blades with washer fluid
or water applied with a soft sponge or
cloth.
CHANGING THE WIPER
BLADES
You can manually move the wiper arms
when the ignition is off. This allows for ease
of blade replacement and cleaning under
the blades.
1. Pull the wiper blade and arm away
from the glass.
