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:

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-12106) 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 bottle.
