2.0L L4 Engine
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. If using this mixture,
nothing else needs to be added.
2.4L L4 Engine
Use a 50/50 mixture of deionized
water and DEX-COOL coolant.
If using this mixture, nothing else
needs to be added.
These mixtures:
. Give freezing protection down to
− 37°C ( − 34°F), outside
temperature.
. Give boiling protection up to
129°C (265°F), engine
temperature.
. Protect against rust and
corrosion.
. Will not damage aluminum parts.
. Help keep the proper engine
temperature.
Notice: If improper coolant
mixture, inhibitors, or additives
are used in the vehicle
’ s cooling
system, the engine could
overheat and be damaged. Too
much deionized water or clean
drinkable water can freeze and
crack engine cooling parts. The
repairs would not be covered by
the warranty. Use only the proper
mixture of engine coolant for the
cooling system. See
Recommended Fluids and
Lubricants on page 11
‑ 14 .
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:
2.0L L4 Engine
A 50/50 mixture of clean drinkable
water and DEX-COOL coolant.
2.4L L4 Engine
A 50/50 mixture of deionized water
and DEX-COOL coolant.
Be sure the cooling system is cool
before this is done.
