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.
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine off and cold, the coolant level should be between
the ranges indicated on the bottle. Some darkening of the
coolant bottle will occur over time. This is normal.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant bottle. Do
not overfill. See your authorized dealer to properly fill
the cooling system.
Points to Remember
When the vehicle is stopped after a few miles of
operation, you may observe vapor coming from the front
of the engine compartment. This is normally a result of
moisture from rain, snow, or high humidity accumulat-
ing on the radiator and being vaporized when the
thermostat opens, allowing hot coolant to enter the
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 bottle.
Check coolant freeze point in the system.
If frequent coolant additions are required, the cooling
system should be pressure tested for leaks.
Maintain coolant concentration at 50% ethylene glycol
antifreeze (minimum) in water for proper corrosion
