CHANGING THE ENGINE AIR
FILTER - 6.7L DIESEL

Air Filter Restriction Gauge

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 and cause the engine to
lose power or shut down.

E163372

The restriction gauge, on the upper housing
of the air filter assembly, measures the
vacuum inside the air filter. The more the
air filter is dirty or 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 mi (12,000 km). If you operate
your vehicle in extremely dusty conditions,
check and reset the gauge at least every
500 mi (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
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.

We recommend the following actions after
operating the vehicle up to 200 mi
(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 dries after
about 15–30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.

DRAINING THE FUEL FILTER
WATER TRAP - 6.7L DIESEL

Your vehicle is equipped with a diesel fuel
conditioner module located on the
frame-rail under the driver-side floorboard
near the transmission.

You should drain water from the
module assembly whenever the
warning light comes on and the

message center directs you to drain the
water separator. This will occur when
approximately 8.45 fl oz (250 ml) of water
accumulates in the module. If you allow
the water level to exceed this level, the
water may pass through to the engine and
may cause fuel injection equipment
damage.

Draining the Diesel Fuel
Conditioner Module (DFCM)

WARNING:

Do not drain the

water-in-fuel separator while the engine
is running. Failure to follow this warning
may result in fire, serious injury, death or
property damage.

Note:

If you drain the diesel fuel conditioner

module while the system is running air will
enter into the fuel system. The engine will
not operate properly if air enters the system.

Note:

With fuel tank levels above 3⁄4 tank

it may be necessary to loosen the bowl three
turns before opening the drain. This will
actuate an anti-siphon valve at the fuel and
water separator inlet and prevent the fuel
from siphoning out of the tank.

Note:

A loose drain valve can allow air to

enter the fuel system and cause drivetrain
issues. The engine will not operate properly.
Be sure that you fully tighten the drain valve.

Stop your vehicle and shut off the
engine.

2. Locate the diesel fuel conditioner

module and place an appropriate
container under the drain port.

E163360

231

Maintenance

3. Rotate the drain counterclockwise until

the O-ring is visible. Allow the diesel
fuel conditioner module to drain for
approximately 25 seconds or until
clean fuel is observed. Rotate the drain
clockwise to tighten it. If no liquid
drains, there may be a clog in the drain.
Have the conditioner module serviced
by an authorized dealer.

4. Make sure that you fully tighten the

drain valve and then remove the
container from under your vehicle.

5. Restart the engine. If the

Water in Fuel

Drain Filter

message and light

continues to illuminate, have the fuel
system checked and repaired.

the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield.

WARNING:

To reduce the risk of

personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system
is under pressure. Steam and hot liquid
can come out forcefully when you loosen
the cap slightly.

WARNING:

Do not add coolant

further than the

MAX

mark.

When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See
