2017 JEEP GRAND CHEROKEE cooling

•Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant (anti-
freeze) 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
operated.
NOTE:
• Some vehicles require special tools to add coolant prop-
erly. 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 recom-
mended 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 to MS.90032) as soon as pos-
sible.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 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 remove the pressure cap while the system is
hot or under pressure.
• Do not use a pressure cap other than the one speci-
fied for your vehicle. Personal injury or engine
damage may result.

Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is a
regulated substance requiring proper disposal. Check with
your local authorities 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 engine coolant (antifreeze) freeze point
or replacing coolant. Advise your service attendant of this.
As long as the engine operating temperature 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 FCA Material Standard MS.90032 should
be added to the coolant bottle. Do not overfill.
Points To Remember
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is normally
a result of moisture from rain, snow, or high humidity
accumulating on the radiator and being vaporized when
the thermostat opens, allowing hot engine coolant (anti-
freeze) to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
• Do not overfill the coolant expansion bottle.
• Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
470 SERVICING AND MAINTENANCE

WARNING!
The temperature grade for this tire is established for a
tire that is properly inflated and not overloaded. Ex-
cessive speed, under-inflation, or excessive loading,
either separately or in combination, can cause heat
buildup and possible tire failure.
STORING THE VEHICLE
If the vehicle should remain stationary for more than a
month, observe the following precautions:
•Park your vehicle in a covered, dry and possibly airy
location the windows open slightly.
• Check that the Electric Park Brake is not engaged.
• Disconnect the negative (-) terminal from the battery
post and be sure that the battery is fully charged. During
storage check battery charge quarterly.
• If you do not disconnect the battery from the electrical
system, check the battery charge every 30 days.
• Clean and protect the painted parts by applying protec-
tive waxes. •
Clean and protect polished metal parts by applying
protective waxes.
• Apply talcum powder to the front and rear wiper blades
and leave raised from the glass.
• Cover the vehicle with an appropriate cover taking care
not to damage the painted surface by dragging across
dirty surfaces. Do not use plastic sheeting which will not
allow the evaporation of moisture present on the surface
of the vehicle.
• Inflate the tires at a pressure of +7.25 psi (+0.5 bar)
higher than recommended on the tire placard and check
it periodically.
• Do not drain the engine cooling system.
• Whenever you leave the vehicle is stationary for two
weeks or more, run idle the engine for approximately
five minutes, with the air conditioning system on and
high fan speed. This will ensure a proper lubrication of
the system, thus minimizing the possibility of damage to
the compressor when the vehicle is put back into opera-
tion.

CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) en-
gine coolant (antifreeze), may result in engine dam-
age and may decrease corrosion protection. Organic
Additive Technology (OAT) engine coolant is differ-
ent and should not be mixed with Hybrid Organic
Additive Technology (HOAT) engine coolant (anti-
freeze) or any “globally compatible” coolant (anti-
freeze). If a non-OAT engine coolant (antifreeze) is
introduced into the cooling system in an emergency,
the cooling system will need to be drained, flushed,
(Continued)
CAUTION! (Continued)
and refilled with fresh OAT coolant (conforming to
MS.90032), by an authorized dealer as soon as pos-
sible.
• 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 coolant (antifreeze).
Use of propylene glycol-based engine coolant (anti-
freeze) is not recommended.
