Your vehicle has been built with an improved engine
coolant that allows extended maintenance intervals. This
coolant can be used up to five Years or 100,000 miles
before replacement. To prevent reducing this extended
maintenance period, it is important that you use the same
coolant throughout the life of your vehicle. Please review
these recommendations for using Hybrid Organic Addi-
tive Technology (HOAT) coolant.
When adding coolant:
The manufacturer recommends using Mopar
Antifreeze/Coolant five Year/100,000 Mile Formula
HOAT (Hybrid Organic Additive Technology).
Mix a minimum solution of 50% HOAT engine coolant
and distilled water. Use higher concentrations (not to
exceed 70%) if temperatures below Ϫ34°F(Ϫ37° C)
Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
solution. The use of lower quality water will reduce
the amount of corrosion protection in the engine
Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE: Mixing coolant types will decrease the life of the
engine coolant and will require more frequent coolant
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant will return to the
radiator from the coolant recovery bottle.
