2011 JEEP GRAND CHEROKEE cooling

WARNING!
•Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is on. You can
be injured by moving fan blades.
• Remove any metal jewelry such as watch
bands or bracelets that might make an
inadvertent electrical contact. You could be
seriously injured.
• Batteries contain sulfuric acid that can burn
your skin or eyes and generate hydrogen
gas which is flammable and explosive.
Keep open flames or sparks away from the
battery.
1. Set the parking brake, shift the automatic
transmission into PARK and turn the ignition to
LOCK.
2. Turn off the heater, radio, and all unneces-
sary electrical accessories.
3. Remove the protective cover over the re-
mote positive (+)battery post. Pull upward on
the cover to remove it. 4. If using another vehicle to jump-start the
battery, park the vehicle within the jumper
cables reach, set the parking brake and make
sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this procedure could result in
personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result
in damage to the charging system of the
booster vehicle or the discharged vehicle.
1. Connect the positive
(+)end of the jumper
cable to the remote positive (+)post of the
discharged vehicle.

when diagnostic testing, or for prolonged
periods during very rough idle or malfunc-
tioning operating conditions.
Cooling System
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the en-
gine coolant (antifreeze) is dirty or rusty in
appearance, the system should be drained,
flushed and refilled with fresh engine coolant
(antifreeze). Check the front of the A/C con-
denser for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from
a garden hose vertically down the face of the
condenser.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and tight-
ness of the connection at the coolant recovery
bottle and radiator. Inspect the entire system
for leaks.
With the engine at normal operating tempera-
ture (but not running), check the cooling sys-
tem pressure cap for proper vacuum sealing by
draining a small amount of engine coolant
(antifreeze) from the radiator drain cock. If the
cap is sealing properly, the engine coolant
(antifreeze) will begin to drain from the coolant
recovery bottle. DO NOT REMOVE THE COOL-
ANT PRESSURE CAP WHEN THE COOLING
SYSTEM IS HOT.
Cooling System – Drain, Flush, and Refill
If the engine coolant (antifreeze) is dirty and
contains a considerable amount of sediment,
clean and flush with reliable cooling system
cleaner. Follow with a thorough rinsing to re-
move all deposits and chemicals. Properly dis-
pose of the old engine coolant (antifreeze).
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
Selection Of Coolant
Use only the manufacturer’s recommended en-
gine coolant (antifreeze). Refer to “Fluids, Lu-
bricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.CAUTION!
•
Mixing of engine coolant (antifreeze), other
than the specified HOAT engine coolant
(antifreeze), may result in engine damage
and may decrease corrosion protection. If a
non-HOAT engine coolant (antifreeze) is
introduced into the cooling system in an
emergency, it should be replaced with the
specified engine coolant (antifreeze) as
soon as possible.

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 engine coolant (antifreeze) 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.
Adding Coolant
Your vehicle has been built with an improved
engine coolant (antifreeze) that allows extended
maintenance intervals. This engine coolant (an-
tifreeze) can be used up to 5 Years or
105,000 miles (168 000 km) before replace-
ment. To prevent reducing this extended main-
tenance period, it is important that you use the
same engine coolant (antifreeze) throughout the
life of your vehicle. Please review these recom-
mendations for using Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze).
When adding engine coolant (antifreeze):
•
The manufacturer recommends using MO-
PA R Antifreeze/ Coolant 5–Year/100,000 Mile
Formula HOAT (Hybrid Organic Additive
Technology) or equivalent.
• Mix a minimum solution of 50% HOAT engine
coolant (antifreeze) and distilled water. Use
higher concentrations (not to exceed 70%) if
temperatures below -34°F (-37°C) are antici-
pated.
• 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
operated.
NOTE:
Mixing engine coolant (antifreeze) types will
decrease the life of the engine coolant (an- tifreeze) and will require more frequent en-
gine coolant (antifreeze) changes.
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 remove
the pressure cap while the system is hot or
under pressure.

WARNING!(Continued)
• 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
(antifreeze) 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
and children, do not store ethylene glycol-
based engine coolant (antifreeze) in open con-
tainers 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 immediately.
Coolant Level
The coolant bottle provides a quick visual
method for determining that the engine coolant
(antifreeze) level is adequate. With the engine
idling, and warm to normal operating tempera-
ture, 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 engine coolant (anti-
freeze). 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, it 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 re-
sult of moisture from rain, snow, or high
humidity accumulating on the radiator and
being vaporized when the thermostat opens,
allowing hot engine coolant (antifreeze) 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 recovery bottle.
• Check engine coolant (antifreeze) freeze
point in the radiator and in the coolant recov-
ery bottle. If engine coolant (antifreeze)
needs to be added, contents of coolant
recovery bottle must also be protected
against freezing.
• If frequent engine coolant (antifreeze) addi-
tions are required, or if the level in the
coolant recovery bottle does not drop when
the engine cools, the cooling system should
be pressure tested for leaks.
• Maintain engine coolant (antifreeze) concen-
tration at 50% HOAT engine coolant (anti-
freeze) (minimum) and distilled water for
proper corrosion protection of your engine,
which contains aluminum components.
• Make sure that the radiator and coolant
recovery bottle hoses are not kinked or ob-
structed.
282

•Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
• Do not change the thermostat for Summer or
Winter operation. If replacement is ever nec-
essary, install ONLY the correct type thermo-
stat. Other designs may result in unsatisfac-
tory cooling performance, poor gas mileage,
and increased emissions.
Brake SystemIn order to assure brake system performance,
all brake system components should be peri-
odically inspected. Refer to the “Maintenance
Schedule” for the proper maintenance inter-
vals.
WARNING!
Riding the brakes can lead to brake failure
and possibly an accident. Driving with your
foot resting or riding on the brake pedal can
result in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency. Fluid Level Check – Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood ser-
vice, or immediately if the brake system warn-
ing lamp indicates system failure.
The brake master cylinder has a translucent
plastic reservoir. On the outboard side of the
reservoir, there is a “MAX” dot and a “MIN” dot.
The fluid level must be kept within these two
dots. Do not add fluid above the MAX mark,
because leakage may occur at the cap.
With disc brakes, the fluid level can be ex-
pected to fall as the brake linings wear. How-
ever, an unexpected drop in fluid level may be
caused by a leak and a system check should
be conducted.
Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
WARNING!
•
Use only manufacturer’s recommended
brake fluid. Refer to “Fluids, Lubricants,
and Genuine Parts” in “Maintaining Your
Vehicle” for further information. Using the
wrong type of brake fluid can severely
damage your brake system and/or impair
its performance. The proper type of brake
fluid for your vehicle is also labeled on the
original factory installed hydraulic master
cylinder reservoir.
• To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed con-
tainer. Keep the master cylinder reservoir
cap secured at all times. Brake fluid in a
open container absorbs moisture from the
air resulting in a lower boiling point. This
may cause it to boil unexpectedly during
hard or prolonged braking, resulting in sud-
den brake failure. This could result in a
accident.
