SERVICING AND MAINTENANCE
SCHEDULED SERVICING
3.6L AND 5.7L ENGINES
These vehicles are equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is time to
take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent
short-trips, trailer tow, and extremely hot or cold
ambient temperatures will influence when the
“Change Oil” or “Oil Change Required” message
is displayed. Severe Operating Conditions can
cause the change oil message to illuminate as
early as 3,500 miles (5,600 km) since last
reset. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
The “Oil Change Required” message will be
displayed in the instrument cluster and a single

282SERVICING AND MAINTENANCE
(Continued)
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 (antifreeze) that meets the
requirements 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)
Formula 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 corro
-
sion 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 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.
NOTE:
Be sure you do not mix the engine coolant
system pressure cap with the intercooler
system pressure cap. These caps are not inter -
changeable.
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.
20_LD_OM_EN_USC_t.book Page 282
SERVICING AND MAINTENANCE283
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 assistance
immediately. Clean up any ground spills
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 (antifreeze) 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 (antifreeze) is
needed to maintain the proper level, only OAT
coolant that meets the requirements of FCA
Material Standard MS.90032 should be added
to the coolant bottle. Do not overfill.
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 compart
-
ment. This is normally a result of moisture from
rain, 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
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) addi-
tions are required, the cooling system should
be pressure tested for leaks.
Maintain engine coolant (antifreeze) concen
-
tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled
water for proper corrosion protection of your
engine which contains aluminum compo -
nents.
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
