SERVICING AND MAINTENANCE 257
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 10Year/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 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 tempera -
tures occurring in the area where the vehicle is operated.
• Some vehicles require special tools to add coolant prop -
erly. 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 authorized
dealer.
• Mixing engine coolant (antifreeze) types is not recom -
mended 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 tank.

The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.

258 SERVICING AND MAINTENANCE
The image on the coolant system pressure cap is a
reminder that the radiator contains hot engine
coolant under pressure.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is a regu-
lated 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 expansion 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 (anti
-
freeze) in the bottle should be between the “MIN” and
“MAX” marks.
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.
WARNING!
• Do not open hot engine cooling system. Never add engine coolant (antifreeze) when the engine is over -
heated. Do not loosen or remove the cap to cool an over -
heated 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.

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 mois-
ture 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.
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 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 oper -
ation. If replacement is ever necessary, install ONLY the
correct type thermostat. Other designs may result in unsat -
isfactory engine coolant (antifreeze) performance, poor
gas mileage, and increased emissions.

CAUTION!
• Mixing of engine coolant (antifreeze) other than speci -
fied 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 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 autho -
rized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products. Do not use additional rust inhib -
itors or antirust products, as they may not be compat -
ible with the radiator 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 (anti -
freeze) is not recommended. CAUTION!
