SERVICING AND MAINTENANCE 301
damage. If HOAT and OAT coolant are mixed in
an emergency, have an authorized dealer drain,
flush, and refill with OAT coolant (conforming to
MS.90032) as soon as possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that
engine coolant will return to the radiator from the
coolant expansion bottle/recovery tank (if
equipped).
The cap should be inspected and cleaned if there
is an y

accumulation of foreign material on the
sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is
a regulated substance requiring proper disposal.
Check with your local authorities to determine the
disposal rules for your community. To prevent
ingestion 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
by a child or pet, seek emergency assistance
immediately.
Coolant Level
The coolant expansion bottle provides a quick
visual method for determining that the coolant
level is adequate. With the engine off and cold, the
level of the coolant (antifreeze) in the bottle should
be between the “MAX” and “MIN” lines marked on
the bottle.
As long as the engine operating temperature is
satisf
actory, the coolant bottle need only be
checked once a month.
When additional coolant is needed to maintain the
proper

level, it should be added to the coolant
bottle. Do not overfill.
See an authorized dealer for service.
Cooling System Notes
NOTE:
When the vehicle is stopped after a few miles/kilo -
meters of operation, you may observe vapor
c oming

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 n

o 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 coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant needs to be added, 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
alumi n

um components.
WARNING!
Do not open hot engine cooling system. Never
add engine coolant (antifreeze) when the
engine is overheated. 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.
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.
