Jeep grand cherokee 2016 Operating Information Manual page 341

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:
• Some vehicles require special tools to
add coolant properly. Failure to fill these
systems properly could lead to severe
internal engine damage. If any coolant is
needed to be added to the system please
contact your local authorized dealer.
• 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 authorized dealer drain, flush, and refill
with OAT coolant (conforming
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!
• 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 over-
heated engine. Heat causes pressure to
build up in the cooling system. To prevent
scalding or injury, do not remove the pres-
sure 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/
coolant pressure cap unless checking for en-
gine coolant (antifreeze) freeze point or replac-
ing coolant. Advise your service attendant of
this. As long as the engine operating tempera-
ture is satisfactory, the coolant bottle need only
be checked once a month.
When additional engine coolant (antifreeze) is
needed to maintain the proper level, only OAT
coolant that meets the requirements of Chrysler
