The cooling s stem 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"
in the Index.
A 50/50 mixture of water and DEX-COOL"
coolant will:
0 Give freezing protection down to -34°F (-37°C).
c
F
Give boiling protection up to 265°F (129°C).
0 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.
Use a mixture of one-half cEean wccfer (preferably
distilled) and one-half DEX-COOL'" coolant which
won't damage aluminum parts.
If you use this mixture,
you don't need to add anything else.

Downloaded from www.Manualslib.com manuals search engine Adding only plain water to your cooling system
can be dangerous. Plain water? or some other
liquid like alcohol, can boil before
the proper
coolant mis will. Your vehicle’s coolant warning
system is set
for the proper coolant mix. With
phi11 water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned.
Use a 50/50 mix of clean
water and
DEX-COOL@ coolant.
NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty. Too much water in the mix 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.
I NOTICE:
If you use the proper cooIant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.

The surge tank is located next to the engine block on the
passenger’s side
of the engine.
The cooling system
is under a lot of pressure when it
is hot. If the CHECK COOLANT LEVEL message
appears
on the DIC, you will need to add coolant.
engine and radiator are hot can allow steam and
scalding liquids to blow
out and burn you badly.
Never turn the surge tank pressure cap
-- even a
little -- when the engine and radiator are hot.
When your engine is cold, the coolant level should be at
the FULL COLD mark, which is 2.5 inches (6.4 cm)
below the base
of the fill neck. Use a flashlight as
necessary to see into the tank.
