What to Use

{

WARNING

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 −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.

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.
