Checking the Fluid Level
0
0
Park your vehicle on a level place. Keep the
engine running.
With the parking brake applied, place the shift lever
in
PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds
in each range. Then, position the shift
lever in
PARK (P).
Let the engine run at idle for three to five minutes. Then, without shutting
off the engine,
follow
these steps:
The automatic transaxle fluid dipstick is the red loop
located toward the rear
of the engine.
1. Pull out the dipstick and wipe it with a clean rag or
paper towel.
2. Push it back in all the way, wait three seconds and
then pull
it back out again.

Engine Coolant
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 or if you need to add coolant to your
radiator, 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).
0 Give boiling protection up to 265 OF ( 129 O C).
0 Protect against rust and corrosion.
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
-- 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 dean 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.
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 mix
will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain 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
50150 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.
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.

Checking Coolant
I
When your engine is cold, the coolant level should be at
the
COLD mark or a little higher. When your engine is
warm, the level should
be up to the HOT mark or a
little higher. If
this light comes on,
it means you’re low on
engine coolant.
Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture at the coolnnt wcovev tank, but be
careful not to spill it.
If the coolant recovery tank is completely empty, add
coolant to the radiator. (See “Engine Overheating” in
the Index.)

ProCarManuals.com

Radiator Pressure Cap
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almost
never have to add coolant at the radiator.
Never turn the radiator pressure cap
-- even a
little -- when the engine and radiator are hot.
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.
NOTICE:
Your radiator cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant
loss and possible engine damage
from overheating. Be sure the arrows on the cap
line up with the overflow tube
on the radiator
filler neck.
When you replace your radiator pressure cap, an
AC@
cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches
a preset temperature.
When you replace your thermostat, an
AC@ thermostat
is recommended.

Power Steering Fluid How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then unscrew the cap and
wipe
the dipstick with a clean rag. Replace the cap and
completely tighten
it. Then remove the cap again and
look at
the fluid level on the dipstick.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired. When
the engine compartment
is hot, the level should be
at the
HOT mark. If the fluid is at the ADD mark, you
should add fluid.

system fixed, since a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak. If
you add fluid
when your linings are worn, then you’ll have too much
fluid when
you get new brake linings. You should add
(or remove) brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @I (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean
the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.
A
If you have too much brake fluid, it can spill on the
engine. The fluid
will burn if the engine is hot
enough. You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work is done on the brake hydraulic system.
When your brake fluid falls to a low level, your brake
warning light will come on. See “Brake System Warning
Light” in the Index.
CAUTION:
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.

Brake Wear
NOTICE:
0
0
Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index. Your
Buick has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make
a
high-pitched warning sound when the brake pads are worn
and new pads are needed. The sound may come and go or
be heard all the time
your vehicle is moving (except when
you are
pushing on the brake pedal firmly).
I
I
The brake wear warning sound means that soon
your brakes won’t work well. That could lead
to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
