get the overheat warning. Your engine could
catch fire and you
or others could be burned.
Use a 50/50 mixture of clean water and
DEX-COOL@ coolant.
1 NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
I 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.
I. 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.

engine and
let it run until you can feel the upper
radiator hose getting
hot. Watch out for the engine
cooling fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level
is lower, add
more
of the proper mixture to the coolant surge tank
until the level reaches about 2.5 inches (6.4 cm)
below the base of the filler neck.

5. Then replace the pressure cap. Be sure the arrows on
the pressure cap
line up like this.
Start the engine and allow it to warm up. If the CHECK
COOLANT LEVEL message does not appear on the
Driver Information Center, coolant
is at the proper fill
level.
If a CHECK COOLANT LEVEL message does
appear, repeat Steps
1 through 3 or see your dealer.

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.
J
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).
Give boiling protection up to 265 “F (1 29°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 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
-0 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.

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half clean water (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.
A CAUTION:
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 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 wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use a
50/50 mixture of clean water and
DEX-COOL@ coolant.
NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged. The repair cost wouldn’t 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.
I NOTICE:
~~~~~
If you use the proper coolant, 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 Driver Information Center (DIC), you
will need to add coolant.
A CAUTION:
Turning the surge tank pressure cap when the
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.

Downloaded from www.Manualslib.com manuals search engine Wheel Replacement
~eplace any wheel that is bent. cracked, or badly ruslea
or corroded.
If wheel nuts keep coming loose, the wheel,
wheel bolts
and wheel nuts should be replaced. If the
wheel leaks air, replace
it (except some aluminum
wheels, which can sometimes be repaired). See your
dealer
if any of these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have the same load-carrying
capacity. diameter, width, offset and be mounted the
same way as
the one it replaces.
If
you need to replace any of your wheels, wheel bolts
or wheel nuts. replace them
only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel
nuts for your
Cadillac model.
A CAUTION:
Using the wrong replacement wheels, wheel
bolts or wheel nuts
on your vehicle can be
dangerous. It could affect the braking and
handling
of your vehicle, make your tires lose
air and make you lose control. You could have a
collision in which you or others could be injured.
Always use the correct wheel, wheel bolts and
wheel nuts for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer
or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for more
information.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination
of fuses and circuit
breakers.
This greatly reduces the chance of fires
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with
a new one of the identical size
and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can “borrow” one that has the same
amperage. Pick some feature of your vehicle that
you can get along without
-- like the radio or
cigarette lighter -- and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
There
are two fuse blocks in your vehicle: the engine
compartment fuse block and the rear compartment
fuse block.
