Selection Of Coolant
Use only the manufacturers recommended coolant
Ú page 301.
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 compat-
ible" coolant. If a non-OAT engine coolant is
introduced into the cooling system in an emer-
gency, 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 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 ten 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
SERVICING AND MAINTENANCE
Material Standard MS.90032. When adding
engine coolant:
We recommend using Mopar® Antifreeze/

Coolant 10 Year/150,000 mile (240,000 kilo-
meters) Formula OAT (Organic Additive Tech-
nology) meeting 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.
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.
