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
5-30.
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:
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.
