Engine Coolant

The cooling system in your vehicle is ﬁlled with

DEX-COOL

engine coolant. This coolant is designed

to remain in your vehicle for ﬁve years or 150,000 miles

(240 000 km), whichever occurs ﬁrst, if you add only

DEX-COOL

extended life coolant.

The following explains your cooling system and how to

add coolant when it is low. If you have a problem

with engine overheating or if you need to add coolant to

the radiator, see Engine Overheating on page 5-29.

A 50/50 mixture of clean, drinkable water and

DEX-COOL

coolant will:

• Give freezing protection down to −34°F (−37°C).

• Give boiling protection up to 265°F (129°C).

• Protect against rust and corrosion.

• Help keep the proper engine temperature.

• Let the warning lights and gages work as

they should.

Notice: Using coolant other than DEX-COOL

may

cause premature engine, heater core, or radiator

corrosion. In addition, the engine coolant may

require changing sooner, at the ﬁrst maintenance

service after each 25,000 miles (41 500 km) or

24 months, whichever occurs ﬁrst. Any repairs

would not be covered by your warranty. Always use

DEX-COOL

(silicate-free) coolant in your vehicle.

What to Use

Use a mixture of one-half clean, drinkable water and

one-half DEX-COOL

coolant which will not damage

aluminum parts. If you use this coolant mixture, you do

not need to add anything else.

{CAUTION:

Adding only plain water to your cooling

system can be dangerous. Plain water, or

some other liquid such as alcohol, can boil

before the proper coolant mixture will. Your

vehicle’s coolant warning system is set for the

proper coolant mixture. With plain water or the

wrong mixture, your engine could get too hot

but you would not get the overheat warning.

Your engine could catch ﬁre and you or others

could be burned. Use a 50/50 mixture of clean,

drinkable water and DEX-COOL

coolant.
