WARNING!
• The warning words "DO NOT OPEN HOT"
on the cooling system pressure cap are a
safety precaution. Never add engine cool-
ant (antifreeze) when the engine is over-
heated. 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.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant
(antifreeze) is a regulated substance requiring
proper disposal. Check with your local authori-
ties to determine the disposal rules for your
community. To prevent ingestion by animals or
children do not store ethylene glycol-based
engine coolant (antifreeze) in open containers
or allow it to remain in puddles on the ground.

PAGE POSITION: 198
If ingested by a child or pet, seek emergency
assistance immediately. Clean up any ground
spills immediately.
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 temperature, the level of the
engine coolant (antifreeze) in the bottle should
be between the "ADD" and "FULL" lines shown
on the bottle.
The radiator normally remains completely full,
so there is no need to remove the radiator cap
unless checking for the coolant freeze point or
replacing the engine coolant (antifreeze). Ad-
vise your service attendant of this. As long as
the engine operating temperature is satisfac-
tory, 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 ob-
serve vapor coming from the front of the
engine compartment. This is normally a re-
sult 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 recovery bottle.
• Check the coolant freeze point in the radiator
and in the coolant recovery bottle. If engine
coolant (antifreeze) needs to be added, the
contents of the coolant recovery bottle must
also be protected against freezing.
