into the passenger compartment. In addition, inspect the
exhaust system each time the vehicle is raised for an oil
change or lubrication. Replace as required.
WARNING!Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to Exhaust Gas in the Safety Tips section of this
manual. COOLING SYSTEM
WARNING!² When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition
switch to the LOCK position. The fan is tempera-
ture controlled and can start at anytime the igni-
tion switch is in the ON position.
² You or others can be badly burned by hot coolant
or steam from your radiator. If you see or hear
steam coming from under the hood, don't open the
hood until the radiator has had time to cool. Never
try to open a cooling system pressure cap when the
radiator is hot.388 MAINTAINING YOUR VEHICLE

² Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
solution. The use of lower quality water will reduce
the amount of corrosion protection in the engine
cooling system.
Please note that it is the owner's responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE: Mixing coolant types will decrease the life of the
engine coolant and will require more frequent coolant
changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to ensure that coolant will return to the
radiator from the coolant recovery bottle. The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!² The warning words ªDO NOT OPEN HOTº on
the cooling system pressure cap are a safety pre-
caution. Never add coolant 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 scald-
ing or injury, do not remove the pressure cap while
the system is hot or under pressure.
² Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result. MAINTAINING YOUR VEHICLE 391

Disposal of Used Engine Coolant
Used ethylene glycol based engine coolant 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 engine coolant in open
containers or allow it to remain in puddles on the
ground. If ingested by a child, contact a physician
immediately. Clean up any ground spills immediately.
Coolant Level
4 Cylinder Engines Ð 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 coolant in the
bottle should be between the ªADDº and ªFULLº lines,
shown on the bottle. 6 Cylinder Engines Ð the level of the coolant in the
pressurized coolant bottle should be between the
ªCOLDº and ªFULLº range on the bottle when the
engine is cold.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
coolant freeze point or replacing coolant. Advise your
service attendant of this. As long as the engine operating
temperature is satisfactory, 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.
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 high392 MAINTAINING YOUR VEHICLE
