DEALER SERVICE — 3.0L DIESEL
Your authorized dealer has the qualified ser-
vice personnel, special tools, and equipment
to perform all service operations in an expert
manner. Service Manuals are available which
include detailed service information for your
vehicle. Refer to these Service Manuals be-
fore attempting any procedure yourself.
NOTE:
Intentional tampering with emissions control
systems may void your warranty and could
result in civil penalties being assessed
against you.
WARNING!
You can be badly injured working on or
around a motor vehicle. Only do service
work for which you have the knowledge
and the proper equipment. If you have any
doubt about your ability to perform a ser-
vice job, take your vehicle to a competent
mechanic.
Engine Air Cleaner Filter
WARNING!
The air induction system (air cleaner,
hoses, etc.) can provide a measure of pro-
tection in the case of engine backfire. Do
not remove the air induction system (air
cleaner, hoses, etc.) unless such removal
is necessary for repair or maintenance.
Make sure that no one is near the engine
compartment before starting the vehicle
with the air induction system (air cleaner,
hoses, etc.) removed. Failure to do so can
result in serious personal injury.
CAUTION!
All air entering the engine intake must be
filtered. The abrasive particles in unfil-
tered air will cause rapid wear to engine
components.
Refer to the “Maintenance Plan” for the
proper maintenance intervals.
CAUTION!
Many aftermarket performance air filter
elements do not adequately filter the air
entering the engine. Use of such filters can
severely damage your engine.
Draining Fuel/Water Separator
Filter
The fuel filter/water separator filter housing is
located above the rear axle next to the fuel
tank. The best access to this water drain valve
is from under the vehicle.
CAUTION!
• Do not drain the fuel/water separator filter when the engine is running.
• Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.
If water is detected in the water separator
while the engine is running, or while the
ignition switch is in the ON position, the
“Water In Fuel Indicator Light” will illumi-
249

nate and an audible chime will be heard. At
this point, you should stop the engine and
drain the water from the filter housing.
CAUTION!
If the “Water In Fuel Indicator Light” re-
mains on, DO NOT START the engine be-
fore you drain water from the fuel filter to
avoid engine damage.
If the “Water In Fuel Indicator Light” comes
on and a single chime is heard while you are
driving, or with the ignition in the ON posi-
tion, there may be a problem with your water
separator wiring or sensor. See your autho-
rized dealer for service.
Upon proper draining of the water from the
fuel filter, the “Water In Fuel Indicator Light”
will remain illuminated for approximately
10 seconds. If the water was drained while
the engine was running, the “Water In Fuel
Indicator Light” may remain on for approxi-
mately three minutes. NOTE:
Care should be taken in disposing of used
fluids from your vehicle. Used fluids, indis-
criminately discarded, can present a problem
to the environment. Contact an authorized
dealer, service station, or government agency
for advice on recycling programs and for
where used fluids and filters can be properly
disposed of in your area.
Drain the fuel/water separator filter when the
“Water In Fuel Indicator Light” is ON. Within
10 minutes of vehicle shutdown, turn the
filter drain valve (located on the bottom of the
filter housing) counterclockwise to drain fuel/
water, then turn the ignition switch to the ON
position, and allow any accumulated water to
drain. Leave the drain valve open until all
water and contaminants have been removed.
When clean fuel is visible, close the drain
valve by turning it clockwise, and turn the
ignition switch to OFF.
If more than two ounces or 60 milliliters of
fuel have been drained, follow the directions
for “Priming If The Engine Has Run Out Of
Fuel.”
Underbody Mounted Fuel Filter
Replacement
NOTE:
Using a fuel filter that does not meet the
manufacturer's filtration and water separat-
ing requirements can severely impact fuel
system life and reliability.
CAUTION!
• Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.
• Do not prefill the fuel filter when install-
ing a new fuel filter. There is a possibility
debris could be introduced into the fuel
filter during this action. It is best to
install the filter dry and allow the in-tank
lift pump to prime the fuel system.
1. Turn engine off.
2. Place a drain pan under the fuel filter assembly.
3. Open the water drain valve, and let any accumulated water drain.
4. Close the water drain valve.
