Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) OAT or
HOAT, is a regulated substance requiring proper dis-
posal. Check with your local authorities to determine
the disposal rules for your community. To prevent inges-
tion by animals or children, do not store ethylene glycol-
based coolant in open containers or allow it to remain
in puddles on the ground, clean up any ground spills
immediately. If ingested, seek emergency assistance
immediately.
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 cool-
ant (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 satisfac-
tory, 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/
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 expansion bottle.
•
Check the freezing point of the coolant in the radia-
tor and in the coolant expansion bottle. If deter-
mined that more engine coolant needs to be added
to the radiator, the contents of the coolant expan-
sion 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 mini-
mum of 50% OAT coolant (conforming to MS.90032)
and distilled water for proper corrosion protection of
your engine which contains aluminum components.
•
Make sure that the coolant expansion bottle over-
flow hoses are not kinked or obstructed.
•
Keep the front of the radiator clean. With air condi-
tioning, keep the front of the condenser clean.
•
Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs
may result in unsatisfactory engine system perfor-
mance, poor gas mileage, and increased emissions.
CHARGE AIR COOLER —
INTER-COOLER (DIESEL ENGINE)
The charge air cooler is positioned in front of the radia-
tor 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.
BRAKE SYSTEM
In order to ensure brake system performance, all brake
system components should be inspected periodically.
For the proper maintenance intervals
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high
brake temperatures, excessive lining wear, and pos-
sible brake damage. You would not have your full
braking capacity in an emergency.
