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 ﬁve years or 150,000 miles

(240 000 km), 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 on page 5-31

What to Use

{ CAUTION:

Adding only plain water to the cooling system can

be dangerous. Plain water, or some other liquid

such as alcohol, can boil before the proper coolant

mixture will. The vehicle’s 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 −34°F (−37°C),

outside temperature.

• Gives boiling protection up to 265°F (129°C),

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.

Notice: If extra inhibitors and/or additives are used

in the vehicle’s cooling system, the vehicle could be

damaged. Use only the proper mixture of the engine

coolant listed in this manual for the cooling system.

See Recommended Fluids and Lubricants on

page 6-12 for more information.
