Fan
Inspection
Check the fan for cracks and bent or broken blades. If any
of these conditions exist, you must replace the fan. Make
sure it is securely mounted.
NOTE:This service procedure must be performed by a
trained service technician. Make arrangements with your
authorized Dodge Truck Dealer for this inspection.
Charge Air Cooler (Inter-Cooler)
The charge air cooler is positioned between 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 100degrees Fahrenheit. 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.
Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component which may cause heat
damage or mechanical wear.
402 MAINTAINING YOUR VEHICLE

With disc brakes the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to Fluids, Lubricants and Genuine Parts for the
correct Fluid type.
WARNING!
Use of a brake fluid that may have a lower initial
boiling point, or unidentified as to specification,
may result in sudden brake failure during hard
prolonged braking. You could have an accident.
WARNING!
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.
CAUTION!
Do not allow a petroleum-base fluid to contaminate
the brake fluid. Seal damage and loss of brake
performance may result.

Lubricant Selection for 6-Speed Manual
Transmission — If Equipped
If it becomes necessary to add fluid or change the fluid,
be sure to use the same lubricant or equivalent. Refer to
Fluids, Lubricants and Genuine Parts for the correct
lubricant type.
Automatic Transmission
Fluid Level Check
The fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is at
normal operating temperature. Operation of the trans-
mission with an improper fluid level will greatly reduce
the life of the transmission and of the fluid. Check the
fluid level whenever the vehicle is serviced.
Procedure For Checking Fluid Level
To properly check the automatic transmission fluid level,
the following procedure must be used:1. The vehicle must be on level ground.
2. The engine should be running at curb idle speed for a
minimum of 60 seconds.
3. Fully apply parking brake.
4. Place the gear selector briefly in each gear position
ending with the lever in N (Neutral).
5. Remove the dipstick and determine if the fluid is hot
or warm. Hot fluid is approximately 180°F (82°C) which
is the normal operating temperature after the vehicle has
been driven at least 15 miles. The fluid can not be
comfortably held between the finger tips. Warm is when
fluid is between 85° - 125°F (29° - 52°C).
6. Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
a. If the fluid is hot, the reading should be in the
crosshatched area marked “OK”.

INTEGRATED POWER MODULE
An integrated Power Module is located in the engine
compartment near the battery. This center contains car-
tridge fuses and mini fuses. A description of each fuse
and component may be stamped on the inside coverotherwise the cavity number of each fuse is stamped on
the inside cover that corresponds to the following chart.

1. Disconnect the battery negative (-) cable before remov-
ing the cover.
2. Use specified fuses only.
3. Always properly reinstall the cover.VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
•Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Integrated Power Module, located in the
engine compartment. The I.O.D. cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
•The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
•As an alternative to the above steps you may, discon-
nect the negative cables from both batteries.
NOTE:When reinstalling the IOD fuse, the gages in the
Instrument Cluster will do a full sweep, when the
ignition key is cycled to RUN. This is a normal condition.
