What to Use
{
WARNING
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The coolant warning system is set
for the proper coolant mixture.
With plain water or the wrong
mixture, the engine could get too
hot but you would not get the
overheat warning. The engine
could catch fire and you or others
could be burned. Depending on
the engine, use a 50/50 mixture
of deionized water or clean,
drinkable water and DEX-COOL
coolant.
Use a 50/50 mixture of deionized
water or clean, drinkable water and
DEX-COOL coolant. If using this
mixture, nothing else needs to be
added.
This mixture:
.
Gives freezing protection down
to
−
37°C (
−
34°F), outside
temperature.
.
Gives boiling protection up to
129°C (265°F), engine
temperature.
.
Protects against rust and
corrosion.
.
Will not damage aluminum parts.
.
Helps keep the proper engine
temperature.
Notice:
If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much deionized water or
clean, drinkable water in the
mixture can freeze and crack the
engine, radiator, heater core, and
other parts.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service
center, familiar with legal
requirements regarding used
coolant disposal. This will help
protect the environment and your
health.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down.
If coolant is visible but the coolant
level is not at or above the mark
pointed to, add a 50/50 mixture of
deionized water or clean drinkable
water and DEX-COOL coolant.
Be sure the cooling system is cool
before this is done.
