Selection Of Coolant
NOTE:
Mixing of engine coolant (antifreeze) other than speci
-
fied Organic Additive Technology (OAT) engine coolant,
may result in engine damage and may decrease corro
-
sion protection. OAT engine coolant is different and
should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant or any “globally
compatible” coolant. If a non-OAT engine coolant 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 products. Do not use additional rust inhibitors
or antirust products, as they may not be compatible
with the radiator engine coolant and may plug the radi
-
ator.
This vehicle has not been designed for use with
propylene glycol-based engine coolant. Use of
propylene glycol-based engine coolant 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 ten years or
150,000 miles (240,000 km) before replacement. To
prevent reducing this extended maintenance period, it is
important to 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 that meets the
requirements of the manufacturer Material Standard
MS.90032. When adding engine coolant:
We recommend using Mopar® Antifreeze/Coolant
10 Year/150,000 Mile (240,000 km) Formula OAT
that meets the requirements of the manufacturer
Material Standard MS.90032.
Mix a minimum solution of 50% OAT engine coolant
that meets the requirements of the manufacturer
Material Standard MS.90032 and distilled water. Use
higher concentrations (not to exceed 70%) if tempera
-
tures 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 (anti
-
freeze) solution. The use of lower quality water will
reduce the amount of corrosion protection in the
engine cooling system.
NOTE:
It is the owner's responsibility to maintain the proper
level of protection against freezing according to the
temperatures occurring in the area where the vehicle is
operated.
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 a
local authorized dealer.
Mixing engine coolant types is not recommended and
can result in cooling system damage. If HOAT and OAT
coolant are mixed in an emergency, have an authorized
dealer drain, flush, and refill with OAT coolant
(conforming to MS.90032) as soon as possible.
