CAUTION!
• Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technol-
ogy (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 authorized dealer as soon as possible.

CAUTION!
(Continued)
• 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 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.
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 us-
ing Organic Additive Technology (OAT) engine
coolant (antifreeze) that meets the require-
ments of FCA Material Standard MS.90032.
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 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 ex-
ceed 70%) if temperatures below −34°F
(−37°C) are anticipated. Please contact your
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.
