Disposal of Used Engine Coolant
Used Hybrid Organic Additive Technology (HOAT)
antifreeze/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
HOAT antifreeze/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 ground
spills immediately.
Coolant Level
The coolant recovery bottle provides a quick visual
method for determining that the antifreeze/coolant level
is adequate. With the engine idling, and warm to normal
operating temperature, the level of the antifreeze/coolant
should be between the ranges indicated on the bottle.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
antifreeze/coolant freeze point or replacing coolant. Ad-
vise 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 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.
