Buick LaCrosse: 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. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL coolant for
non-eAssist engine(s). Use a
50/50 mixture of deionized water
and DEX-COOL coolant for
eAssist engine(s).
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.
