2004 DODGE DURANGO Owners Manual

Brake System
Power Disc Brakes (Front)
Disc brakes do not require adjustment; however, several
hard stops during the break-in period are recommended
to seat the linings and wear off any foreign material.
Brake Master Cylinders
The fluid level in the master cylinders should be checked
whenever the vehicle is serviced, or immediately if the
brake system warning light is on. If necessary, add fluid
to bring level to the full mark on the side of the reservoir
of the brake master cylinder. Be sure to clean the top of
the master cylinder area before removing the cap. With
disc brakes, fluid level can be expected to fall as the brake
pads wear. Brake fluid level should be checked when
pads are replaced. If the brake fluid level is abnormally
low, check system for leaks.
Refer to Recommended Fluids, Lubricants and Genuine
Parts for correct fluid type.

WARNING!
Use of brake fluid that may have a lower initial
boiling point, or is unidentified, as to specifications
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 on 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 may result.
Brake Hoses
Inspection should be performed whenever the brake
system is serviced or at intervals specified. Inspect hy-
draulic brake hoses for surface cracking, scuffing or worn
spots. If there is any evidence of cracking, scuffing, or
worn spots, the hose should be replaced immediately!
Eventual deterioration of the hose can take place with
possible burst failure.
314 MAINTAINING YOUR VEHICLE

WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any sign of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Automatic Transmission
Fluid Level Check ± 3.7L Engine
This fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is
heated to its normal operating temperature. Operation of
the transmission with an improper fluid level will greatly
reduce the life of the transmission and of the fluid. Check
the fluid whenever the vehicle is serviced for other
reasons.NOTE:Whenever the fluid level is checked, especially
on a vehicle used in severe service, the condition of the
fluid should be noted. If the fluid is dark and has a strong
odor, fluid should be changed.
A physical change in the fluid may be the result of
overheating, resulting in fluid degradation. This is pos-
sible in severe service or if the vehicle is equipped with a
non-factory installed air-conditioning unit.
To check the automatic transmission fluid level properly,
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 feel if the fluid is hot or
warm. Hot fluid is approximately 180ÉF (82ÉC), the
normal operating temperature after the vehicle has been
driven at least 15 miles (24 km). The fluid cannot be
comfortably held between the finger tips. Warm is when
fluid is between 85É and 125ÉF (29É and 52ÉC).
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 ªOKº.
b. If the fluid is warm, the reading should be between
the two holes.
If the fluid level is low, add sufficient fluid to bring to the
proper level.
Fluid is added through the dipstick tube.NOTE:To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
certain that the dipstick cap is properly reseated.
Fluid Level Check ± 4.7L/5.7L Engine
Check the fluid level while the transmission is at normal
operating temperature 180ÉF (82ÉC). This occurs after at
least 15 miles (24 km) of driving. At normal operating
temperature the fluid cannot be held comfortably be-
tween the fingertips.
To check the automatic transmission fluid level properly,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake and press the brake
pedal.

4. Place the gear selector momentarily in each gear
position ending with the lever in P (Park).
5. Remove the dipstick, wipe it clean and reinsert it until
seated.
6. Remove the dipstick again and note the fluid level on
both sides. The fluid level should be between the ªHOTº
(upper) reference holes on the dipstick at normal operat-
ing temperature. Verify that solid coating of oil is seen on
both sides of the dipstick. If the fluid is low, add as
required into the dipstick tube.Do not overfill.After
adding any quantity of oil through the oil fill tube, wait
a minimum of two (2) minutes for the oil to fully drain
into the transmission before rechecking the fluid level.
NOTE:If it is necessary to check the transmissionbelow
the operating temperature, the fluid level should be
between the two ªCOLDº (lower) holes on the dipstick
with the fluid at approximately 70ÉF ( 21ÉC) (room
temperature). If the fluid level is correctly established atroom temperature, it should be between the ªHOTº
(upper) reference holes when the transmission reaches
180ÉF ( 82ÉC). Remember it is best to check the level at the
normal operating temperature.
CAUTION!
Be aware that if the fluid temperature is below 50ÉF
(10ÉC) it may not register on the dipstick. Do not add
fluid until the temperature is elevated enough to
produce an accurate reading.
7. Check for leaks. Release parking brake.
To prevent dirt and water from entering the transmission
after checking or replenishing fluid, make certain that the
dipstick cap is properly reseated. It is normal for the
MAINTAINING YOUR VEHICLE 317

dipstick cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in the
dipstick tube.
Automatic Transmission Fluid And Filter Change
To obtain best performance and long life for automatic
transmissions, the manufacturer recommends that they
be given regular maintenance service by an Authorized
Dodge Dealer or Service Center. It is important that the
transmission be adjusted periodically, the fluid main-
tained at the correct level, and that it be drained and
refilled as specified.
Follow the proper Maintenance Schedule for your type of
driving.
It is important that proper lubricant is used in the
transmission. Refer to Recommended Fluids, Lubricants
and Genuine Parts for correct fluid type. It is important
that the transmission fluid be maintained at the pre-
scribed level using the recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turers recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturers recommended fluid will result in
more frequent fluid and filter changes. Refer to
Recommended Fluids, Lubricants and Genuine Parts
for correct fluid type.
Special Additives
The manufacturer strongly recommends against the ad-
dition of any additives to the transmission. Exception to
this policy is the use of special dyes to aid in detecting
fluid leaks. The use of transmission sealers should be
avoided, since they may adversely affect seals.
318 MAINTAINING YOUR VEHICLE

Transfer Case
Inspect the transfer case for fluid leaks. If a fluid leak is
evident the transfer case fluid level may be low. Have the
transfer case serviced immediately.
CAUTION!
Damage may result from operation of the vehicle
with low transfer case fluid.
The transfer case fluid should be drained and refilled at
the intervals specified.
Lubricant Selection
Refer to Recommended Fluids, Lubricants and Genuine
Parts for correct fluid type.
Axles
Refer to Recommended Fluids, Lubricants and Genuine
Parts for correct fluid type.
The manufacturer does not recommend regularly sched-
uled oil changes for axles in vehicles whose operation is
classified as normal truck service.
NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Rear Axle
Rear Axle fluid levels should be 7/89(22 mm) below the
fill plug hole for 8 1/49axles, and 1 5/89(41 mm) below
the fill plug hole for 9 1/49axles.
MAINTAINING YOUR VEHICLE 319

Front Axle
Front Axle fluid level should be at the bottom of the filler
hole plug.
Selection of Lubricating Grease
The National Lubricating Grease Institute (NLGI) has
developed a symbol (Certification Mark) to aid the
vehicle owner in the proper selection of grease for chassis
components. This symbol, an example shown below, is
located on the grease container and identifies the appli-
cation and quality of the grease.There are two groups
identified, those for wheel
bearings (Letter ªGº) and
those for chassis (Letter
ªLº) lubrication. Perfor-
mance categories within
these groups result in dual
letter designations for
each group. The letter des-
ignations shown in the ex-
ample are the highest
quality level available and when combined as shown can
be used for chassis lubrication. Use only those greases
that have the NLGI symbol on the container along with
the proper quality level for your application.
