480 SERVICING AND MAINTENANCE
Adding Coolant
Your vehicle has been built with an improved engine coolant
(OAT co
olant 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
replace
ment. To prevent reducing this extended mainte-
nance period, it is important that you use the same engine
c
oolant
(OAT coolant conforming to MS.90032) throughout
the life of your vehicle.
Please review these recommendations for using Organic
Additiv
e 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/
150,00
0 Mile (240,000 km) Formula OAT (Organic Additive
Technol
ogy) 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 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 wh
en 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.
NOTE:
• It is the owner's responsibility to maintain the proper level
of pro
tection against freezing according to the tempera-
tures occurring in the area where the vehicle is operated.
• S
ome vehicles require special tools to add coolant prop-
erly. Fa
ilure 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 (antifreeze) types is not recom-
mended
and can result in cooling system damage. If
HOAT an
d OAT coolant are mixed in an emergency, have
a authorized dealer drain, flush, and refill with OAT
coolant (conforming to MS.90032) as soon as possible.
