ACCESSORY DRIVE BELT INSPECTION
When inspecting accessory drive belts, small
cracks that run across the ribbed surface of the
belt from rib to rib, are considered normal.
These are not a reason to replace the belt.
However, cracks running along a rib (not across)
are not normal. Any belt with cracks running
along a rib must be replaced. Also have the belt
replaced if it has excessive wear, frayed cords
or severe glazing.
Accessory Belt (Serpentine Belt)

Conditions that would require replacement:
Rib chunking (one or more ribs has sepa -
rated from belt body)
Rib or belt wear
Longitudinal belt cracking (cracks between
two ribs)
Belt slips
“Groove jumping" (belt does not maintain
correct position on pulley)
Belt broken (Identify and correct problem
before new belt is installed)
Noise (objectionable squeal, squeak, or
rumble is heard or felt while drive belt is in
operation)
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
Such damage is not covered by the New
Vehicle Limited Warranty.WARNING!
Do not attempt to inspect an accessory
drive belt with vehicle running.
When working near the radiator cooling fan,
disconnect the fan motor lead. The fan is
temperature controlled and can start at any
time regardless of ignition mode. You could
be injured by the moving fan blades.
You can be badly injured working on or

228 SERVICING AND MAINTENANCE
(Continued)

Under normal operating conditions, the catalytic
converter will not require maintenance. However,
it is important to keep the engine properly tuned
to ensure proper catalyst operation and prevent
possible catalyst damage.

NOTE:
Intentional tampering with emissions control
s y

stems can result in civil penalties being
assessed against you.

In unusual situations involving grossly
m a

lfunctioning engine operation, a scorching odor
may suggest severe and abnormal catalyst
overheating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, including a
tune-up to manufacturer's specifications, should be
obtained immediately.

To minimize the possibility of catalytic converter
d a

mage:
Do not interrupt the ignition when the trans -
mission is in gear and the vehicle is in
m o

tion.
Do not try to start the vehicle by pushing or
towing the vehicle.
Do not idle the engine with any ignition
components disconnected or removed, such
as when diagnostic testing, or for prolonged
periods during very rough idle or malfunc -
tioning operating conditions.
COOLING SYSTEM
Coolant Checks

Check the engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
w e
ather, where applicable). If the engine coolant
(antifreeze) is dirty or rusty in appearance, the
system should be drained, flushed, and refilled
with fresh engine coolant (antifreeze). Check the
front of the A/C condenser for any accumulation
of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically
down the face of the condenser.

Check the coolant recovery bottle tubing for
b r

ittle rubber, cracking, tears, cuts, and
tightness of the connection at the bottle and
radiator. Inspect the entire system for leaks.
WARNING!

You or others can be badly burned by hot
engine coolant (antifreeze) or steam from your
radiator. If you see or hear steam coming from
under the hood, do not open the hood until the
radiator has had time to cool. Never open a
cooling system pressure cap when the radiator
or coolant bottle is hot.

Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts automati -
cally and may start at any time, whether the
e n

gine is running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the
ignition to the OFF mode. The fan is
temperature controlled and can start at any
time the ignition is in the ON mode.
WARNING!
The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a
safety precaution. Never add engine
coolant (antifreeze) when the engine is
overheated. Do not loosen or remove the
cap to cool an overheated engine. Heat
causes pressure to build up in the cooling
system. To prevent scalding or injury, do not
remove the pressure cap while the system
is hot or under pressure.

SERVICING AND MAINTENANCE 229
Cooling System — Drain, Flush And Refill
NOTE:
Some vehicles require special tools to add
c o

olant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system please contact your local authorized
dealer.
If the engine coolant (antifreeze) is dirty or
c o

ntains visible sediment, have an authorized
dealer clean and flush with OAT coolant
(antifreeze) (conforming to MS.90032).
Refer to the “Maintenance Plan” in (Servicing
a n

d Maintenance” for the proper maintenance
intervals.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
NOTE:

Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technology
(OAT) engine coolant (antifreeze), may result in
engine damage and may decrease corrosion
protection. Organic Additive Technology (OAT)
engine coolant is different and should not be
mixed with Hybrid Organic Additive Technology
(HOAT) engine coolant (antifreeze) or any
“globally compatible” coolant (antifreeze). If a
non-OAT engine coolant (antifreeze) is intro -
duced into the cooling system in an emer-
gency, the cooling system will need to be
d r

ained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032), by an
authorized dealer as soon as possible.

Do not use water alone or alcohol-based
engine coolant (antifreeze) products. Do not
use additional rust inhibitors or antirust prod -
ucts, as they may not be compatible with the
r a

diator engine coolant and may plug the
radiator.
This vehicle has not been designed for use
with propylene glycol-based engine coolant
(antifreeze). Use of propylene glycol-based
engine coolant (antifreeze) is not recom -
mended.
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added
to the system please contact an authorized
dealer.
Adding Coolant

Your vehicle has been built with an improved
engine coolant (OAT coolant conforming to
MS.90032) that allows extended maintenance
intervals. This engine coolant (antifreeze)
can be used up to ten years or 150,000 miles
( 2

40,000 km) before replacement. To prevent
r e

ducing this extended maintenance period, it is
important that you use the same engine coolant
(OAT coolant conforming to MS.90032)
throughout the life of your vehicle.

Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
WARNING! (Continued)

230 SERVICING AND MAINTENANCE
Please review these recommendations for
using Organic Additive Technology (OAT)
engine coolant (antifreeze) that meets the
r e

quirements of FCA Material Standard
MS.90032. When adding engine coolant
(antifreeze):

We recommend using Mopar Antifreeze/
Coolant 10 Year/150,000 Mile (240,000 km)
F o

rmula OAT (Organic Additive Technology)
that meets the requirements of FCA Material
Standard MS.90032.

Mix a minimum solution of 50% OAT engine
coolant that meets the requirements of FCA
Material Standard MS.90032 and distilled
water. Use higher concentrations (not to
exceed 70%) if temperatures below −34°F
(−37°C) are anticipated. Please contact an
authorized dealer for assistance.
Use only high purity water such as distilled or
deionized water when mixing the water/
engine coolant (antifreeze) solution. The use
of lower quality water will reduce the amount
of corrosion protection in the engine cooling
system. NOTE:
It is the owner's responsibility to maintain the
proper level of protection against freezing
according to the temperatures occurring in
the area where the vehicle is operated.
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added
to the system, please contact a local autho
-
rized dealer.
Mixing engine coolant (antifreeze) types is
not recommended and can result in cooling
system damage. If HOAT and OAT coolant are
mixed in an emergency, have a authorized
dealer drain, flush, and refill with OAT coolant
(conforming to MS.90032) as soon as
possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss
of engine coolant (antifreeze), and to ensure
that engine coolant (antifreeze) will return to
the radiator from the coolant recovery bottle.
The cap should be inspected and cleaned if
t h

ere is any accumulation of foreign material on
the sealing surfaces.
Disposal Of Used Coolant

Used ethylene glycol-based coolant (antifreeze) is
a regulated substance requiring proper disposal.
Check with your local authorities to determine the
disposal rules for your community. To prevent
ingestion by animals or children, do not store
ethylene glycol-based coolant in open containers
or allow it to remain in puddles on the ground.
If ingested by a child or pet, seek emergency
as
sistance immediately. Clean up any ground
spills immediately.

WARNING!
The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a
safety precaution. Never add engine
coolant (antifreeze) when the engine is
overheated. Do not loosen or remove the
cap to cool an overheated engine. Heat
causes pressure to build up in the cooling
system. To prevent scalding or injury, do not
remove the pressure cap while the system
is hot or under pressure.
Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.

SERVICING AND MAINTENANCE 231
Coolant Level
The coolant bottle provides a quick visual
method for determining that the coolant level is
adequate. With the engine idling and warm to
normal operating temperature, the level of the
coolant in the bottle should be between the
“ADD” and “FULL” lines, shown on the bottle.
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 (antifreeze). Advise
your service attendant of this. As long as the
engine operating temperature is satisfactory,
the coolant bottle need only be checked once a
month. When additional engine coolant
(antifreeze) is needed to maintain the proper
level, it should be added to the coolant bottle.
Do not overfill. See “Adding Coolant” in
“Servicing and Maintenance” for further
information.
Points To Remember
NOTE:
When the vehicle is stopped after a few miles/
k i

lometers of operation, you may observe vapor
coming from the front of the engine compart -
ment. This is normally a result of moisture from
r a

in, snow, or high humidity accumulating on
the radiator and being vaporized when the ther -
mostat opens, allowing hot engine coolant (anti -
freeze) to enter the radiator.
If an examination of your engine compartment
s h

ows 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) addi-
tions are required, the cooling system should
b e

pressure tested for leaks.

Maintain engine coolant (antifreeze) concen -
tration at a minimum of 50% OAT coolant
( c

onforming to MS.90032) and distilled water
for proper corrosion protection of your engine
which contains aluminum components.

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 ther -
mostat. Other designs may result in unsatis -
factory engine coolant (antifreeze)
p e

rformance, poor gas mileage, and
increased emissions.
