CAUTION! (Continued)
• Do not use water alone or alcohol-based
engine coolant (antifreeze) 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 glycol-based engine cool-
ant (antifreeze). Use of propylene glycol-
based engine coolant (antifreeze) is not
recommended.
Selection of Coolant – 2.2L Diesel
Use only the manufacturer's recommended
coolant. Refer to "Fluids, Lubricants, and Genu-
ine Parts" in "Maintaining Your Vehicle" for
further information.
CAUTION!
• Mixing of coolants other than specified
HOAT engine coolants may result in en-
gine damage and may decrease corrosion
protection. If a non-HOAT coolant is intro-
duced into the cooling system in an emer-
gency, it should be replaced with the speci-
fied coolant as soon as possible.
• Do not use plain water alone or alcohol-
based engine coolant (antifreeze) prod-
ucts. Do not use additional rust inhibitors
or antirust products, as they may not be
compatible with the radiator engine cool-
ant and may plug the radiator.
• This vehicle has not been designed for use
with propylene glycol-based coolants. Use
of propylene glycol-based coolants is not
recommended.
Adding Coolant
Your vehicle has been built with an improved
engine coolant (antifreeze) that allows ex-
tended maintenance intervals. This engine cool-
ant (antifreeze) can be used up to 10 years or
240,000 km before replacement. To prevent
reducing this extended maintenance period, it is
important that you use the same engine coolant
(antifreeze) throughout the life of your vehicle.
Please review these recommendations for us-
ing Organic Additive Technology (OAT) engine
coolant (antifreeze).
When adding engine coolant (antifreeze), a
minimum solution of 50% recommended
MOPAR® Antifreeze/Coolant
240,000 km Formula OAT (Organic Additive
Technology), or equivalent, in water should be
used. 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
deionized water when mixing the water/engine
coolant (antifreeze) solution. The use of lower
quality water will reduce the amount of corro-
sion protection in the engine cooling system.
Please note that 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 oper-
ated.
