Engine Coolant
The cooling system in the vehicle is filled with DEX-COOL® engine coolant. This coolant is designed to remain in the vehicle for 5 years or 240 000 km (150,000 mi), whichever occurs first.
The following explains the cooling system and how to check and add coolant when it is low. If there is a problem with engine overheating, see Engine Overheating
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.
Use a 50/50 mixture of 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 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.
