engine coolant JEEP WRANGLER 2009 Owners Manual

Airbag Warning Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objectslodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

CAUTION! (Continued)
•This vehicle has not been designed for use with
Propylene Glycol based engine coolant (anti-
freeze). Use of Propylene Glycol base engine cool-
ant (antifreeze) is not recommended.
Adding Engine Coolant
Your vehicle has been built with an improved engine
coolant (antifreeze) that allows extended maintenance
intervals. This engine coolant (antifreeze) can be used up
to 5 Years or 102,000 miles (170 000 km) before replace-
ment. To prevent reducing this extended maintenance
period, it is important that you use the same engine
coolant (antifreeze) throughout the life of your vehicle.
Please review these recommendations for using Hybrid
Organic Additive Technology (HOAT) engine coolant
(antifreeze).When adding engine coolant (antifreeze):
•The manufacturer recommends using MOPAR
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 concentra-
tions (not to exceed 70%) if temperatures below -34°F
(-37°C) are anticipated.
•Use only high purity water such as distilled or deion-
ized 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 main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
418 MAINTAINING YOUR VEHICLE

to remain in puddles on the ground. If ingested by a child
or pet, seek emergency assistance immediately. Clean up
any ground spills immediately.
Engine Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant 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 en-
gine coolant (antifreeze). 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 nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized 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 bottle.
•Check the engine coolant (antifreeze) freeze point in
the radiator and in the coolant recovery bottle. If
