you use the same engine coolant (OAT coolant conform-
ing to MS-12106) throughout the life of your vehicle.

Please review these recommendations for using Organic
Additive Technology (OAT) engine coolant (antifreeze)
that meets the requirements of Chrysler Material Stan-
dard 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.

• Mix a minimum solution of 50% OAT engine coolant

that meets the requirements of Chrysler Material Stan-
dard MS-12106 and distilled water. Use higher concen-
trations (not to exceed 70%) if temperatures below
−34° F (−37° C) are anticipated.

• Use only high purity water such as distilled or deion-

ized 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.

Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.

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 your
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-12106) as soon as possible.
