Chrysler 2014 Grand Cherokee SRT Owner's Manual page 280

• Mix a minimum solution of 50% OAT engine
coolant that meets the requirements of
Chrysler Material Standard MS-12106 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
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.
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.
NOTE:
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 autho-
rized dealer drain, flush, and refill with OAT
coolant (conforming to MS-12106) 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 tank.
The cap should be inspected and cleaned if
there is any accumulation of foreign material on
the sealing surfaces.
WARNING!
• The warning words "DO NOT OPEN HOT"
on the cooling system pressure cap are a
safety precaution. Never add engine cool-
ant (antifreeze) when the engine is over-
heated. Do not loosen or remove the cap
to cool an overheated engine. Heat causes
pressure to build up in the cooling system.
To prevent scalding or injury, do not re-
move 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 Engine Coolant
Used ethylene glycol-based engine coolant (an-
tifreeze) is a regulated substance requiring
proper disposal. Check with your local authori-
ties to determine the disposal rules for your
community. To prevent ingestion by animals or
children, do not store ethylene glycol-based
engine coolant in open containers or allow it to
remain in puddles on the ground. If ingested by
a child or pet, seek emergency assistance
immediately. Clean up any ground spills imme-
diately.
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 cap
unless checking for engine coolant (antifreeze)
freeze point or replacing coolant. Advise your
service attendant of this. As long as the engine
operating temperature is satisfactory, the cool-
ant bottle need only be checked once a month.
