CAUTION! (Continued)
(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.
• 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 radiator 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
270
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
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 Chrysler 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 Chrysler Material Standard
MS.90032.
• Mix a minimum solution of 50% OAT engine
coolant that meets the requirements of
Chrysler Material Standard MS.90032 and
distilled water. Use higher concentrations
(not to exceed 70%) if temperatures below
−34° F (−37° C) are anticipated.
• 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.
to MS.90032)
Please note that 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 oper-
ated.
NOTE:
• 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 your local authorized dealer.
• 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
MS.90032) as soon as possible.
