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 10 years or
150,000 miles (240,000 km) before replacement. To
prevent reducing this extended maintenance period, it
is important to use the same engine coolant (OAT cool-
ant conforming to MS.90032) throughout the life of
your vehicle.
Please review these recommendations for using
Organic Additive Technology (OAT) engine coolant that
meets the requirements of the manufacturer 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 the manufacturer Material Stan-
dard MS.90032.
•
Mix a minimum solution of 50% OAT engine coolant
that meets the requirements of the manufacturer
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 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
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.
•
Use care when filling under hood fluids such as
engine oil, washer fluid, antifreeze, etc., to minimize
spillage onto the top of the engine. Any excess fluid
that is spilled onto the top of the engine should be
removed using compressed air or an absorbent
cloth.
•
Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any cool-
ant is needed to be added to the system, please
contact an authorized dealer.
•
Mixing engine coolant types is not recommended
and can result in cooling system damage. If HOAT
and OAT coolant are mixed in an emergency, have
an 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 will return to the radiator from the coolant
expansion bottle/recovery tank if so equipped.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing
surfaces.
WARNING!
•
Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is
overheated. Do not loosen or remove the cap to
cool an overheated engine. Heat causes pressure
to build up in the cooling system. To prevent scald-
ing or injury, do not remove the pressure cap while
the system is hot or under pressure.
•
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or engine
damage may result.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) OAT or
HOAT, is a regulated substance requiring proper dis-
posal. Check with your local authorities to determine
the disposal rules for your community. To prevent inges-
tion by animals or children, do not store ethylene glycol-
based coolant in open containers or allow it to remain
in puddles on the ground, clean up any ground spills
immediately. If ingested, seek emergency assistance
immediately.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine OFF and cold, the level of the engine coolant
(antifreeze) in the bottle should be between the ranges
indicated on the bottle.
The radiator normally remains completely full, so there
is no need to remove the radiator/coolant pressure cap
unless checking for engine coolant freeze point or
