Cooling System – Drain, Flush, And Refill
If the engine coolant (antifreeze) is dirty or
contains visible sediment, have an authorized
dealer clean and flush with OAT coolant (anti-
freeze) (conforming to MS-12106).
Refer to the "Maintenance Schedule" for the
proper maintenance intervals.
Selection Of Coolant
Refer to "Fluids, Lubricants, and Genuine Parts"
in "Maintaining Your Vehicle" for further informa-
tion.
CAUTION!
• Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technology
(OAT) engine coolant (antifreeze), may re-
sult in engine damage and may decrease
corrosion protection. Organic Additive Tech-
nology (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-12106), 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
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 cool-
ant (antifreeze). Use of propylene glycol-
based engine coolant (antifreeze) is not
recommended.
(Continued)
Adding Coolant
Your vehicle has been built with an improved
engine coolant (OAT coolant conforming to MS-
12106) that allows extended maintenance inter-
vals. This engine coolant (antifreeze) can be used
up to ten years or 150,000 miles (240,000 km)
before replacement. To prevent reducing this ex-
tended maintenance period, it is important that
you use the same engine coolant (OAT coolant
conforming to MS-12106) throughout the life of
your vehicle.
Please review these recommendations for us-
ing Organic Additive Technology (OAT) engine
coolant (antifreeze) that meets the require-
ments of Chrysler Material Standard MS-12106.
When adding engine coolant (antifreeze):
• We recommend using MOPAR® Antifreeze/
Coolant 10 Year/150,000 Mile Formula OAT
(Organic Additive Technology) that meets the
requirements of Chrysler Material Standard
MS-12106.
