Inspect the entire system for leaks. DO NOT
REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE:
Some vehicles require special tools to add cool-
ant properly. Failure to fill these systems prop-
erly could lead to severe internal engine dam-
age. If any coolant is needed to be added to the
system please contact your local authorized
dealer.
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.90032).
NOTE:
If equipped with the 6.2L Supercharged engine
the intercooler must be vacuum flushed and
filled. If any coolant is needed to be added to the
system please contact your local authorized
dealer.
Refer to the "Service and Warranty Handbook"
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
Technology (OAT) engine coolant is differ-
ent and should not be mixed with Hybrid
Organic Additive Technology (HOAT) en-
gine coolant (antifreeze) or any "globally
compatible" coolant (antifreeze). If a non-
OAT engine coolant (antifreeze) is intro-
duced 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 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 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) through-
out the life of your vehicle.
Please review these recommendations for using
Organic Additive Technology (OAT) engine cool-
ant (antifreeze) that meets the requirements of
FCA Material Standard MS.90032. When add-
ing 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 wa-
ter. Use higher concentrations (not to exceed
70%) if temperatures below −34°F (−37°C)
are anticipated. Please contact your autho-
rized dealer for assistance.
• Use only high purity water such as distilled or
deionized water when mixing the water/
engine coolant (antifreeze) solution. The use
