Dodge 2009 Durango Automobile User Manual


 
Please review these recommendations for using Hybrid
Organic Additive Technology (HOAT) coolant (anti-
freeze).
When adding coolant (antifreeze):
The manufacturer recommends using MOPAR
Antifreeze/Coolant 5 Year/100,000 Mile Formula
HOAT (Hybrid Organic Additive Technology).
Mix a minimum solution of 50% HOAT coolant (anti-
freeze) 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 deion-
ized water when mixing the water/TPIM coolant
(antifreeze) solution. The use of lower quality water
will reduce the amount of corrosion protection in the
engine cooling system.
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 (antifreeze) types will decrease
the life of the TPIM coolant (antifreeze) and will require
more frequent coolant (antifreeze) changes.
TPIM Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
