(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
(an
tifreeze) 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
glyco
l-based engine coolant (antifreeze). Use of propylene
glycol based engine coolant (antifreeze) is not recom
-
mended.
• S
ome vehicles require special tools to add coolant prop-
erl
y. Failure to fill these systems properly could lead to
seve
re 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
repl
acement. To prevent reducing this extended mainte-
nance period, it is important that you use the same engine
c
ool
ant (OAT coolant conforming to MS.90032) throughout
the life of your vehicle.
Please review these recommendations for using Organic
Addi
tive Technology (OAT) engine coolant (antifreeze) that
meets the requirements 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
Tech
nology) that meets the requirements of FCA Material
Standard MS.90032.
• Mix a minimum solution of 50% OAT engine coolant that
mee
ts 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
wate
r, 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.
