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
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly malfunctioning
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
damage:
Do not shut off the engine or interrupt the igni-
tion when the transmission is in gear and the
vehicle is in motion.
Do not try to start the engine by pushing or
towing the vehicle.
Do not idle the engine with any spark plug wires
disconnected or removed, such as when diag
-
nostic testing, or for prolonged periods during
very rough idle or malfunctioning operating
conditions.
NOTE:The vehicle exhaust system may be equipped with
an Electronic Exhaust Valve (EEV) system, if the
exhaust system is replaced with aftermarket
products a Malfunction Indicator Lamp (MIL) will
illuminate.
COOLING SYSTEM CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause
serious damage to the engine.
Damage to the catalytic converter can result if
your vehicle is not kept in proper operating condi -
tion. In the event of engine malfunction, particu-
larly involving engine misfire or other apparent
loss of performance, have your vehicle serviced
promptly. Continued operation of your vehicle with
a severe malfunction could cause the converter to
overheat, resulting in possible damage to the
converter and vehicle.
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 radi -
ator 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 automatically and may
start at any time, whether the engine is
running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the igni -
tion to the OFF mode. The fan is temperature
controlled and can start at any time the igni -
tion is in the ON mode.

260SERVICING AND MAINTENANCE
Coolant Checks
Check engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather,
where applicable). If the engine coolant is dirty, the
system should be drained, flushed, and refilled
with fresh Organic Additive Technology (OAT)
coolant (conforming to MS.90032) by an
authorized dealer. Check the front of the radiator
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 brittle
rubber, cracking, tears, cuts, and tightness of the
connection at the bottle and radiator. Inspect the
entire system for leaks. DO NOT REMOVE THE
COOLANT PRESSURE CAP WHEN THE COOLING
SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE:
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.
If the engine coolant (antifreeze) is dirty or contains
visible sediment, have an authorized dealer clean and
flush with Organic Additive Technology (OAT) coolant
(conforming to MS.90032).
For the proper maintenance intervals Úpage 245.
Selection Of Coolant
For further information Ú page 300.
NOTE:
Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) engine
coolant, may result in engine damage and may
decrease corrosion protection. OAT engine coolant
is different and should not be mixed with Hybrid
Organic Additive Technology (HOAT) engine coolant
or any “globally compatible” coolant. If a non-OAT
engine coolant is introduced into the cooling system
in an emergency, the cooling system will need to be
drained, 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 products. Do not use additional rust
inhibitors or anti-rust products, as they may not
be compatible with the radiator engine coolant
and may plug the radiator.
This vehicle has not been designed for use with
propylene glycol-based engine coolant. Use of
propylene glycol-based engine coolant is not
recommended.
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 10 years or
150,000 miles (240,000 km) before replacement.
To prevent reducing 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.
Please review these recommendations for using
Organic Additive Technology (OAT) engine coolant
that meets the requirements of the manufacturer
Material Standard MS.90032. When adding
engine coolant:
We recommend using Mopar® Antifreeze/
Coolant 10 Year/150,000 Mile (240,000 km)
Formula OAT that meets the requirements of the
manufacturer Material Standard MS.90032.
Mix a minimum solution of 50% OAT engine
coolant that meets the requirements of the
manufacturer 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.
21_LD_OM_EN_USC_t.book Page 260

SERVICING AND MAINTENANCE261
Use only high purity water such as distilled or
deionized water when mixing the water/engine
coolant 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 an authorized dealer.
Mixing engine coolant types is not recom -
mended and can result in cooling system
damage. If HOAT and OAT coolant are mixed in
an emergency, have an 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 will return to the radiator from the coolant
expansion bottle/recovery tank (if equipped).
The cap should be inspected and cleaned if there
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,
clean up any ground spills immediately. If ingested,
seek emergency assistance immediately.
Coolant Level
The coolant bottle provides a quick visual method
for determining that the coolant level is adequate.
With the engine off and cold, the level of the engine
coolant (antifreeze) in the bottle should be
between the ranges indicated on the bottle.
The radiator normally remains completely full, so
there is no need to remove the radiator/coolant
pressure cap unless checking for engine coolant
freeze point or replacing coolant. 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 is needed to
maintain the proper level, only OAT coolant that
meets the requirements of manufacturer Material
Standard MS.90032 should be added to the
coolant bottle. Do not overfill.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilo
-
meters 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 (antifreeze) to
enter the radiator.
WARNING!
Do not open hot engine cooling system. 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.
