maintenance DODGE JOURNEY 2019 Service Manual

3.6L Engine —The level of the coolant in the pressurized
coolant bottle should be between the “COLD” and “FULL”
range on the bottle when the engine is cold.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
coolant freeze point or replacing engine coolant (anti-
freeze). Advise your service attendant of this. As long as
the engine operating temperature is satisfactory, the cool-
ant bottle need only be checked once a month. When
additional engine coolant (antifreeze) is needed to main-
tain the proper level, it should be added to the coolant
bottle. Do not overfill. See “Adding Coolant” section for
additional information.
Points To Remember
NOTE: When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is normally
a result of moisture from rain, snow, or high humidity
accumulating on the radiator and being vaporized when
the thermostat opens, allowing hot engine coolant (anti-
freeze) to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate. •
Do not overfill the coolant expansion bottle.
• Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• 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 emissions.

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible
brake damage. You would not have your full braking
capacity in an emergency.
Master Cylinder — Brake Fluid Level Check
Check the fluid level in the master cylinder immediately if
the “Brake Warning Light” indicates system failure.
Check the fluid level in the master cylinder when perform-
ing underhood services.
Clean the top of the master cylinder area before removing
the cap. If necessary, add fluid to bring the fluid level up to
the requirements described on the brake fluid reservoir.Overfilling of fluid is not recommended because it may
cause leaking in the system.
Fluid level can be expected to fall as the brake pads wear.
Brake fluid level should be checked when pads are re-
placed. However, low fluid level may be caused by a leak
and a checkup may be needed.
Use only manufacturer’s recommended brake fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information.
WARNING!
•
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The
proper type of brake fluid for your vehicle is also
identified on the original factory installed hydraulic
master cylinder reservoir.

336 SERVICING AND MAINTENANCE

WARNING!(Continued)
•To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use only the manufacturer’s specified transmission fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.
NOTE:
No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder, and will require more frequent fluid and
filter changes. Refer to “Fluids And Lubricants” in
“Technical Specifications” for fluid specifications.
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis-
sion Fluid (ATF) is an engineered product and its perfor-
mance may be impaired by supplemental additives. There-
fore, do not add any fluid additives to the transmission.
The only exception to this policy is the use of special dyes
8
SERVICING AND MAINTENANCE 337

for diagnosing fluid leaks. Avoid using transmission seal-
ers as they may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
Fluid Level Check — Four-Speed Automatic
Transmission
Use the following procedure to check the transmission
fluid level properly:
1. Park the vehicle on level ground.
2. Run the engine at normal idle speed for at least 60seconds, and leave the engine running for the rest of this
procedure.
3. Fully apply the parking brake, and press the brake pedal.
4. Place the gear selector momentarily into each gear position (allowing time for the transmission to fully
engage in each position), ending with the transmission
in PARK. 5. Wipe the area around the dipstick clean to prevent dirt
from entering the transmission.
6. Remove the dipstick and determine if the fluid is hot or cold. You can also read the transmission fluid tempera-
ture using the instrument cluster. Refer to Instrument
Cluster Display inGetting To Know Your Instrument
Panel for further information. Hot fluid is approxi-
mately 180°F (82°C), which is the normal operating
temperature after the vehicle is driven at least 15 miles
(24 km). Hot fluid cannot be held comfortably between
the fingertips. Cold fluid is at a temperature of approxi-
mately 80°F (27°C).
7. Wipe the dipstick clean and reinsert it until seated. Then, remove the dipstick and note the fluid level on
both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid if
the actual level is at or above the hole.
• If the fluid is hot, the fluid level should be in the
crosshatched area marked “HOT” (between the upper
two holes in the dipstick).
• If the fluid is cold, the fluid level should be between
the lower two holes in the area marked “COLD”.
338 SERVICING AND MAINTENANCE

If the fluid level is low, add fluid through the dipstick tube
to bring it to the proper level. Do not overfill. After adding
any quantity of oil through the dipstick tube, wait at least
two minutes for the oil to fully drain into the transmission
before rechecking the fluid level.
NOTE:If it is necessary to check the transmission below
the operating temperature, the fluid level should be be-
tween the two COLD (lower) holes on the dipstick with the
fluid at approximately 80°F (27°C). If the fluid level is
correctly established at 80°F (27°C), it should be between
the HOT (upper) reference holes when the transmission
reaches 180°F (82°C). Remember it is best to check the level
at the normal operating temperature.
8. Check for leaks. Release the parking brake.
CAUTION!
• Using a transmission fluid other than the manufac-
turer ’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder, and will require more frequent fluid and
filter changes. Refer to “Fluids And Lubricants” in
“Technical Specifications” for fluid specifications.
(Continued)
CAUTION! (Continued)
•Dirt and water in the transmission can cause serious
damage. To prevent dirt and water from entering the
transmission after checking or replenishing fluid,
make sure that the dipstick cap is re-seated properly.
Fluid Level Check — Six-Speed Automatic
Transmission
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required, therefore the transmis-
sion filler tube is capped and no dipstick is provided. An
authorized dealer can check your transmission fluid level
using a special service dipstick. If you notice fluid leakage
or transmission malfunction, visit an authorized dealer
immediately to have the transmission fluid level checked.
Operating the vehicle with an improper fluid level can
cause severe transmission damage.
