SERVICING AND MAINTENANCE379
Coolant Level
The coolant bottle provides a quick visual method
for determining that the coolant level is adequate.
With the engine in the 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
freeze point or replacing coolant. Advise your
service attendant of this. As long as the engine
operating temperature is satisfactory, the coolant
only needs to be checked once a month.
When additional engine coolant 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.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilo -
meters 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 (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 expansion bottle.
Check the freezing point of the coolant in the
radiator and in the coolant expansion bottle. If
determined that more engine coolant needs to
be added to the radiator, the contents of the
coolant expansion bottle must also be protected
against freezing.
If frequent engine coolant additions are
required, the cooling system should be pressure
tested for leaks.
Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corro
-
sion protection of your engine which contains
aluminum components.
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. With air
conditioning, keep the front of the condenser
clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces -
sary, install ONLY the correct type thermostat. Other designs may result in unsatisfactory
engine system performance, poor gas mileage,
and increased emissions.
CHARGE AIR COOLER — INTER-COOLER
(D
IESEL ENGINE)
The charge air cooler is positioned in front of the
radiator and the air conditioner condenser. Air
enters the engine through the air cleaner and
passes through the turbocharger, where it is
pressurized. This pressurized air rapidly reaches
high temperature. The air is then directed through
a hose to the charge air cooler and through
another hose to the intake manifold of the engine.
This cooling process enables more efficient
burning of fuel resulting in fewer emissions.
To guarantee optimum performance of the system,
keep the surfaces of the charge air cooler,
condenser and radiator clean and free of debris.
Periodically check the hoses leading to and from
the charge air cooler for cracks or loose clamps
resulting in loss of pressure and reduced engine
performance.

STORING THE VEHICLE If you are storing your vehicle for more than 3
weeks, we recommend that you take the following
steps to minimize the drain on your vehicle's
battery:
Disconnect the negative cable from the battery.
If your vehicle is equipped with Stop/Start
system then disconnect both the main and
supplemental negative battery cables.
Any time you store your vehicle or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
setting. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
If assistance is needed to disconnect the
battery system, see an authorized dealer.

Battery Cable Disconnect

NOTE:
You must isolate the supplemental battery
connection point, as well as the main battery
terminal from the post, as shown in the image,
to fully de-energize both batteries for storage. If
assistance is needed to disconnect the battery
system, see an authorized dealer.
Do not disconnect the Intelligent Battery Sensor
(IBS), or your Stop/Start system may not func -
tion for up to 24 hours, due to the IBS being set
into learn mode.
BODYWORK
PROTECTION FROM ATMOSPHERIC
A
GENTS
Vehicle body care requirements vary according to
geographic locations and usage. Chemicals that
make roads passable in snow and ice and those
that are sprayed on trees and road surfaces during
other seasons are highly corrosive to the metal in
your vehicle. Outside parking, which exposes your
vehicle to airborne contaminants, road surfaces on
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 rings,
watch bands and bracelets that could make
an inadvertent electrical contact. You could be
seriously injured.
Vehicles with the Stop/Start system will be
equipped with two batteries. Both the main
and the supplemental batteries must be
disconnected to completely de-energize the
12 Volt electrical system.
Serious injury or death could result if you do
not disconnect both batteries. To learn how to
properly disconnect, see an authorized dealer.
CAUTION!
If the negative battery cables are not isolated
properly it can cause a potential power spike or
surge in the system, resulting in damage to
essential electrical components.
