NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other
parts. So
use the recommended coolant.
A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don't spill coolant
on a hot engine.
1. You can remove the coolant surge tank pressure cap
when
the cooling system, including the coolant surge
tank pressure cap and upper radiator hose,
is no
longer hot. Turn the pressure cap slowly
counterclockwise until it first stops. (Don't press
down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.

4. With the coolant surge tank pressure cap off, start
the engine and let it run
until you can feel the upper
radiator hose getting hot. Watch
out for the
engine fans.

surge tank may be lower.
If the level is lower, add
more of the proper mix to the coolant surge tank
until the level reaches about 2.5 inches (6.4 cm)
below the
bass of the filler neck.
5. Then replace the pressure cap. Be sure the arrows on
the pressure cap line up like this.

on the
Driver Information Center. coolant
is at the proper fill
level.

appear. repeat Steps 1 through 3 or see your dealer.

When you put the cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure
you fully install the cap.
If you need a new cap, be sure to get the right
type. Your dealer can get one for you.
If you get
the wrong type, it may not
fit or have proper
venting, and your fuel tank and emissions system
might be damaged.

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.
8
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.
