5. Remove lid using a socket or strap wrench. Rotatecounterclockwise for removal. Remove used o-ring
and discard it.
6. Remove the used filter cartridge from the housing and dispose of according to your local regulations.
7. Wipe clean the sealing surfaces of the lid and housing.
8. Install new o-ring back into ring groove on the filter housing and lubricate with clean engine oil.
NOTE: WIF sensor is re-usable. Service kit comes with
new o-ring for filter canister and WIF sensor.Priming If The Engine Has Run Out Of Fuel
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
1. Add a substantial amount of fuel to the tank, approxi- mately 2 to 5 gal (8L to 19L).
2. Turn ignition switch to the start position to engage starter for one second, return ignition switch to run
position. This will activate in tank fuel pump for
approximately 15 seconds. Repeat this process twice.
3. Start the engine using the “Normal Starting” proce- dure. Refer to “Starting Procedures” in “Starting and
Operating” for further information.

•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased emis-
sions.
Charge Air Cooler — Inter-Cooler
The charge air cooler is positioned below the radiator and
the air conditioner condenser. Air enters the engine
through the air cleaner and passes through the turbo-
charger, where it is pressurized. This pressurized air
rapidly reaches high temperature. The air is then directed
through a hose to the charge air cooler and through
another hose to the intake manifold of the engine. The air
entering the engine has been cooled by about 50° to 100°F
(10° to 38°C). This cooling process enables more efficient
burning of fuel resulting in fewer emissions. To guarantee optimum performance of the system, keep
the surfaces of the charge air cooler, condenser and
radiator clean and free of debris. Periodically check the
hoses leading to and from the charge air cooler for cracks
or loose clamps resulting in loss of pressure and reduced
engine performance.
Brake System
Brake Master Cylinder — Brake Fluid Level Check
The fluid level of the master cylinder should be checked
when performing under the hood service, or immedi-
ately if the “Brake System Warning Light” indicates
system failure.
The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a
“MAX” mark and a “MIN” mark. The fluid level must be
kept within these two marks. Do not add fluid above the
full mark because leakage may occur at the cap.
296 MAINTAINING YOUR VEHICLE

NOTE:If it is necessary to check the transmission below
the operating temperature, the fluid level should be
between the two “COLD” (lower) holes on the dipstick
with the fluid at 60-70°F / 16-21°C for 68RFE transmis-
sion, or 68-86°F / 20-30°C for AS69RC transmission. Only
use the COLD region of the dipstick as a rough reference
when setting the fluid level after a transmission service
or fluid change. Re-check the fluid level, and adjust as
required, once the transmission reaches normal operating
temperature.
CAUTION!
If the fluid temperature is below 50°F (10°C) it may
not register on the dipstick. Do not add fluid until
the temperature is elevated enough to produce an
accurate reading. Run the engine at idle, in PARK, to
warm the fluid. 8. Reinsert the dipstick. Check for leaks. Release the
parking brake.
NOTE: To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
sure that the dipstick cap is properly reseated. It is
normal for the dipstick cap to spring back slightly from
its fully seated position, as long as its seal remains
engaged in the dipstick tube.
Fluid And Filter Changes
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
In addition, change the fluid and filter(s) if the fluid
becomes contaminated (with water, etc.), or if the trans-
mission is disassembled for any reason.

Noise Control System Required Maintenance &
Warranty
All vehicles built over 10,000 lbs. (4 535 kg) Gross Vehicle
Weight Rating and manufactured for sale and use in the
United States are required to comply with the Federal
Government’s Exterior Noise Regulations. These vehicles
can be identified by the Noise Emission Control Label
located in the operator’s compartment.
Required Maintenance For Noise Control Systems
The following maintenance services must be performed
every six months or 7,500 miles (12 000 km) whichever
comes first, to assure proper operation of the noise
control systems. In addition, inspection and service
should be performed anytime a malfunction is observed7
MAINTAINING YOUR VEHICLE 303

or suspected. Proper maintenance of the entire vehicle
will help the effectiveness of the noise control systems.
Exhaust System
Inspect the entire exhaust system for leaks and damaged
parts. Devices such as hangers, clamps, and U-bolts
should be tight and in good condition. Damaged compo-
nents, burned or blown out mufflers, burned or rusted
out exhaust pipes should be replaced according to the
procedures and specifications outlined in the appropriate
service manual.
Air Cleaner Assembly
Inspect air cleaner housing for proper assembly and fit.
Make certain that the air cleaner is properly positioned
and that the cover is tight. Check all hoses leading to the
air cleaner for tightness. The air filter element must also
be clean and serviced according to the instructions out-
lined in the Maintenance Schedule section of this manual.Tampering With Noise Control System Prohibited
Federal law prohibits the following acts or the causing
thereof: (1) the removal or rendering inoperative by any
person, other than for purposes of maintenance, repair, or
replacement, of any device or element of design incorpo-
rated into any new vehicle for the purpose of noise
control prior to its sale or delivery to the ultimate
purchaser or while it is in use, or (2) the use of the vehicle
after such device or element of design has been removed
or rendered inoperative by any person.
Among those acts presumed to constitute tampering are
the acts listed below.
AIR CLEANER
•Removal of the air cleaner.
• Removal of the air cleaner filter element from the air
cleaner housing.

ComponentFluid, Lubricant, or Genuine Part
Crankcase
Ventilation Filter We recommend you use MOPAR CCV Filter.
Fuel Selection Use good quality diesel fuel from a reputable supplier in your vehicle. Federal law requires that you must fuel this vehicle with Ultra Low Sulfur Highway Diesel fuel (15 ppm Sulfur
maximum) and prohibits the use of Low Sulfur Highway Diesel fuel (500 ppm Sulfur
maximum) to avoid damage to the emissions control system.
For most year-round service, No. 2 diesel fuel meeting ASTM specification D-975 Grade S15
will provide good performance.
If the vehicle is exposed to extreme cold (below 20°F or -7°C), or is required to operate at
colder-than-normal conditions for prolonged periods, use climatized No. 2 diesel fuel or
dilute the No. 2 diesel fuel with 50% No. 1 diesel fuel. This will provide better protection
from fuel gelling or wax-plugging of the fuel filters.
This vehicle is fully compatible with biodiesel blends up to 5% biodiesel meeting ASTM
specification D-975.Pickup models, and Chassis Cab models configured with optional B20
capability, are additionally compatible with 20% biodiesel meeting ASTM specification
D-7467.
