Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts, and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.
Cooling System — Drain, Flush, and Refill
If the engine coolant (antifreeze) is dirty or contains a
considerable amount of sediment, clean and flush with a
reliable cooling system cleaner. Follow with a thorough
rinsing to remove all deposits and chemicals. Properly
dispose of the old engine coolant (antifreeze).
Refer to the “Maintenance Schedule” in Section 8 of this
manual for the proper maintenance intervals.
Selection Of Coolant
Use only the manufacturer’s recommended coolant. Re-
fer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.
CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified HOAT engine coolant (antifreeze), may
result in engine damage and may decrease corro-
sion protection. If a non-HOAT engine coolant
(antifreeze) is introduced into the cooling system
in an emergency, it should be replaced with the
specified engine coolant (antifreeze) as soon as
possible.
•Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use addi-
tional rust inhibitors or antirust products, as they
may not be compatible with the engine coolant
(antifreeze) and may plug the radiator.

NOTE:Mixing engine coolant (antifreeze) types will
decrease the life of the engine coolant (antifreeze) and
will require more frequent coolant changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that engine coolant
(antifreeze) 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!
•The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a safety pre-
caution. Never add engine coolant (antifreeze)
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 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 en-
gine 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 authorities to determine the disposal
rules for your community. To prevent ingestion by ani-
mals or children, do not store ethylene glycol based
engine coolant (antifreeze) 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 —the coolant bottle provides a quick
visual method for determining that the engine coolant
(antifreeze) 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 be-
tween the “ADD” and “FULL” lines, shown on the bottle.6 Cylinder Engines —the level of the engine coolant
(antifreeze) in the pressurized coolant bottle should be
between the “COLD” and “FULL” 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
engine coolant (antifreeze) freeze point or replacing cool-
ant. 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 addi-
tional 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 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 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 engine coolant (antifreeze) freeze point in the
radiator and in the coolant recovery bottle. If engine
coolant (antifreeze) needs to be added, contents of
coolant recovery bottle must also be protected against
freezing.
•If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks.
•Maintain engine coolant (antifreeze) concentration at
50% HOAT engine coolant (antifreeze) (minimum)
and distilled water for proper corrosion protection of
your engine, which contains aluminum components.
•Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
