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 5 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, see
Engine Overheating on
page 5-27.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®
coolant will:
•
Giving 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: When adding coolant, it is important that
you use only DEX-COOL
®
(silicate-free) coolant.
If coolant other than DEX-COOL
®
is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the engine
coolant will require change sooner — at 30,000 miles
(50,000 km) or 24 months, whichever occurs first.
Damage caused by the use of coolant other
than DEX-COOL
®
is not covered by your new vehicle
warranty.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL
®
coolant which won’t damage
aluminum parts. If you use this coolant mixture,
you don’t need to add anything else.
