Jeep 2006 Liberty - Manual (Page 336)

When additional antifreeze/coolant is needed to main-
tain the proper level, it should be added to the coolant
recovery 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 water 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 antifreeze/coolant freeze point in the system.
• If frequent antifreeze/coolant additions are required,
or if the level in the recovery bottle does not drop
when the engine cools, the cooling system should be
pressure tested for leaks.
• Maintain engine coolant/anti-freeze concentration to
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 obstructed.
• Keep the front of the radiator clean. Also, 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 necessary, install
