256 Vehicle Care
Warning (Continued)
eyes are still irritated or otherwise
feel abnormal, seek immediate
medical attention.
If the engine coolant gets on your
skin, rinse it off using a soap with
a large amount of water. Also,
if abnormality is seen, seek
medical attention.
Engine coolant is flammable, and
therefore, it must be kept away
from flames and other heat
sources. Engine coolant also
could ignite if it comes in contact
with a hot surface, such as the
exhaust manifold. Exercise
caution to prevent this from
happening.
You and others could be seriously
injured.
Preparing Engine Coolant
To prevent the engine damage to
freezing of the engine coolant and
to protect the cooling system from
corrosion, a mixture of DEX-COOL
type antifreeze and water. If the
engine of the vehicle is at
− 30 °C
( − 22 °F) or above, the coolant
concentration should be 50%. Direct
use of
“ 50/50 Pre-diluted ” product
which is already diluted to 50%
concentration is recommended.
If the outside temperature engine or
vehicle is used at
− 30 °C ( − 22 °F)
or below, coolant concentration of
55% is recommended.
It is the owner ’ s responsibility to:
.
Maintain the engine cooling
system freeze protection at or
above
− 30 °C ( − 22 °F) (at or
below − 30 °C ( − 22 °F) in colder
climates to ensure protection
against corrosion and loss of
engine coolant from boiling.
A 50/50 (55/45 for colder
climates) mixture of DEX-COOL
type antifreeze and water will
provide freeze protection to at or
above
− 30 °C ( − 22 °F), (at or
below − 30 °C ( − 22 °F) in colder
climates) and boil protection to
128 °C (262 °F). Periodic
replacement of engine coolant is
needed to replenish the
anticorrosion additives that wear
out with use. Engine coolant has
become dark in color shows that
it needs to be changed.
.
Use only DEX-COOL type
recommended coolant.
.
Do not use methanol-base
antifreeze, alcohol or plain water
alone in your vehicle at any time.
They will boil at a lower point
than that at which the engine
coolant temperature gauge will
warn of overheating, and they do
not provide proper protection
against corrosion.
Engine Coolant Quantity

0 367 . After changing the engine
coolant, check that the engine
coolant is up to the specified level.
