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.

Notice:

If you use an improper coolant mixture,

your engine could overheat and be badly damaged.
The repair cost would not be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core and
other parts.

If you have to add coolant more than four times a year,
have your dealer check your cooling system.

Notice:

If you use extra inhibitors and/or additives

in your vehicle’s cooling system, you could
damage your vehicle. 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.
