CHANGING THE ENGINE AIR
FILTER - 6.7L DIESEL

Air Filter Restriction Gauge

WARNING

To reduce the risk of vehicle damage
and/or personal burn injuries do not
start your engine with the air filter

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.

E163372

The restriction gauge, located on the upper
housing of the air filter assembly, measures
the vacuum inside the air filter. The more
the air filter is restricted (dirty, clogged),
the higher the vacuum reading.

Check the air filter restriction gauge
whenever you open the hood to perform
general engine maintenance or at least
every 7,500 miles (12,000 km). If you
operate your vehicle in extremely dusty
conditions, check and reset the gauge at
least every 500 miles (800 km), or two
weeks, whichever comes first. Change the

air filter when the restriction gauge reads
near the change filter line and the gauge
is yellow. If you allow the restriction gauge
to reach maximum restriction you can
affect your engine performance and fuel
economy.

Note: Do not blow out the air filter element
with compressed air since the compressed
air could damage the filter paper.

Note: Do not rely on filter appearance
alone. A filter which appears to be dirty may
actually have several thousand miles
(kilometers) of life remaining.

E163373

After installation of the new filter element,
reset the gauge by pressing the reset
button on top of the gauge.

The following actions are recommend after
operating the vehicle up to 200 miles (320
km) in heavy snowfall or extreme rain:
•

Snow: At the earliest opportunity, open
the hood and clear all the snow and ice
from the air filter housing inlet (do NOT
remove the foam filter) and reset the
air filter restriction gauge.

•

Extreme rain: The air filter will dry after
about 15–30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.

Air Filter Replacement

When replacing the air filter element, use
a Motorcraft® air filter element.  See
Motorcraft Parts (page 257).

Note: Failure to use the correct air filter
element may result in severe engine
damage.

1.

Locate the mass airflow sensor
electrical connector on the air inlet
tube. This connector will need to be
unplugged. Unlock the locking clip on
the connector, then squeeze and pull
the connector off the air inlet tube.
