Engine Coolant
Notice: If an improper coolant mixture is used, the engine could overheat and be damaged. The repair cost would not be covered by the warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core, and other parts.
For the gasoline engine, a 50/50 mixture of clean water and DEX-COOL® coolant should be used. If this mixture is used, nothing else needs to be added. This mixture will—
-
give freezing protection down to –34°F (–37°C);
-
give boiling protection up to 265°F (129°C);
-
protect against rust and corrosion;
-
not damage aluminum parts;
-
help keep the proper engine temperature.
Notice: If extra inhibitors and/or additives are used in the vehicle's cooling system, the cooling system could be damaged. Use only the proper mixture of the engine coolant and water listed here for the cooling system.
