Cooling System Pressure Cap
KNOWING
The cap must be fully tightened to prevent loss of
YOUR
engine coolant (antifreeze), and to ensure that engine
VEHICLE
coolant (antifreeze) will return to the radiator from the
coolant recovery tank.
SAFETY
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing sur-
faces.
STARTING
AND
DRIVING

Disposal Of Used Coolant
Used ethylene glycol-based engine coolant is a regu-
lated substance requiring proper disposal. Check with

your local authorities to determine the disposal rules
for your community. To prevent ingestion by animals or

WARNING!
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 im-
mediately.
Coolant Level
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
kilometers of operation, you may observe vapor com-
ing 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 vapor-
ized when the thermostat opens, allowing hot coolant
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.
