236 SERVICING AND MAINTENANCE

This vehicle has not been designed for use
with propylene glycol-based engine coolant
(antifreeze). Use of propylene glycolbased
engine coolant (antifreeze) is not
recommended.

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 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 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 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.
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 autho-
rized 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 OAT coolant
(conforming to MS.90032) as soon as
possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss
of engine coolant (antifreeze), and to ensure
that engine coolant (antifreeze) will return to
the radiator from the coolant recovery bottle.
The cap should be inspected and cleaned if
there is any accumulation of foreign material on
the sealing surfaces.
