Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove
it again,
keeping the tip down, and check the level.
When to Add Oil
If the oil is at or below the ADD mark, then you’ll
need to add some oil. But
you must use the right
kind. This part explains what kind
of oil to use. For
crankcase capacity, see “Capacities and Specifications”
in the Index.
Turn off the engine and give the oil
20 minutes to drain
back into
the oil pan. If you don’t, the oil dipstick might
not show the actual level. NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the
cross-hatched area that
shows the proper
operating range, your engine could be damaged.

L
Operating the engine with the air cleaner off
can cause you or others to be burned. The air
cleaner not only cleans the air, it stops flame if
the engine backfires.
If it isn’t there, and the
engine backfires, you could be burned. Don’t
drive with it
off, and be careful working on the
engine with the air cleaner
off.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine
oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous ten-ain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services”
in the Index.

How to Check
Because this operation can be a little difficult, you may
choose to have this done
at your Buick dealer Service
Department.
If you do it yourself, be sure to follow all
the
instructions here, or you could get a false reading on
the dipstick.
NOTICE:
~ Too much or too little fluid can damage your
1 transaxle. Too much can mean that some of the
fluid could come out and fall
on hot engine parts
or exhaust system parts, starting a fire. Be sure
to
get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level
if you have been driving:
0 When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
~ operating temperature, which is 180°F to 200°F
1 I (82°C to 93°C).
Get the vehicle warmed
up by driving about 15 mues
(24 km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F (lO"C), you may
have to drive longer.

in
PARK (P).
3. 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).
4. Let the engine run at idle for three to five minutes,
Then, without shutting off the engine, follow these steps:
The transaxle dipstick
handle is the red loop
near the back 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.
3. Check both sides of the
dipstick, and read the
lower level: The fluid
level must be in the'
cross-hatched area.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended
Fluids and Lubricants’’
in the Index.
If the fluid level is low, add
only enough of the proper
fluid to bring the level into the cross-hatched area on
the dipstick.

Pull out the dipstick.
Using
a long-neck funnel, add enough fluid at the
dipstick hole to bring
it to the proper level. It doesn’t
take much fluid, generally less than a pint
(0.5 L).
Don t overfill. We recommend you use only fluid
labeled DEXRONO-111, because fluid with that label
is made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON@-I11
is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level
as
described under “How to Check.”
When
the correct fluid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL
TM (orange-colored, silicate-free) engine
coolant. This coolant
is designed to remain in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
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 the proper coolant for
your Buick 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:
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 coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.

:king Coolant
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.

Radiator Pressure Cap
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

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.

How To Check Power Steering Fluid
When the engine compartment is cool, 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.
3.1 L L82 (Code M) Engine When
the engine
compartment
is hot,
the level should be at the
H mark. When it’s cold,
the level should be at the
C mark. If the fluid is at
the ADD mark, you
should add fluid. 3.8L L36 (Code K) Engine
When the engine compartment is hot, the level should be
at the
HOT mark. When it’s cold, the level should be at
the FULL COLD mark, If the fluid is at the
ADD mark, you should add fluid.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants”
in the Index. Always use the proper fluid.
Failure to use
the proper fluid can cause leaks and
damage hoses and seals.
