230 SERVICING AND MAINTENANCE
Refer to the "Service And Warranty Handbook
(Auto Biography)" for the proper maintenance
intervals.
Selection Of Coolant
Refer to "Fluids And Lubricants" in "Technical
Specifications" for further information.
NOTE:
Mixing of engine coolant (antifreeze) other

than specified Organic Additive Technology
(OAT) engine coolant (antifreeze), may result
in engine damage and may decrease corro-
sion protection. Organic Additive Technology
(OAT) engine coolant is different and should
not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (anti-
freeze) 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.
Do not use water alone or alcohol-based

engine coolant (antifreeze) products. Do not
use additional rust inhibitors or antirust prod-
ucts, 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 coolant
(antifreeze). Use of propylene glycolbased
engine coolant (antifreeze) is not recom-
mended.
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 an authorized
dealer.
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 10 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
using 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 (240,000 km)
Formula OAT (Organic Additive Technology) that
meets the requirements of FCA Material Stan-
dard 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
exceed 70%) if temperatures below −34°F
(−37°C) are anticipated. Please contact an
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.
