8. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch
out for the
engine hns.
9. By this time the coolant level inside the radiator
filler neck may be lower.
If the level is lower, add
more
of the proper mix through the filler neck until
the level reaches the base of the filler neck.
10. Then replace the pressure cap. At any time during
this procedure
if coolant begins to flow out of the
filler neck, reinstall the pressure
cap. Be sure the
BI-~OWS on the pressure cap line up like this.
1 1 - Check the coolant in the recovery tank. The level in
the coolant recovery tank should be at the HOT
mark when the engine is hot or at the COLD mark
when the engine
is cold.

What Kind of Oil to Use
Oils of the proper quality for your vehicle can be
identified by looking for the “Starburst” symbol. The
“Starburst” symbol indicates that the oil has been
certified by the American Petroleum Institute (API), and
is preferred for use in your gasoline engine.
If you change your own oil,
be sure you use oil that has
the “Starburst” symbol on
the front of the oil
container.
If you have your
oil changed for you, be sure
the oil put into your engine
is American Petroleum
Institute certified for
gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:
As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use SAE 1OW-30 if it’s going
to be
0°F (- 18°C) or above. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as SAE
20W-50.

As shown in the chart, SAE 1OW-30 is best for your
vehicle. However, you can use
SAE 5W-30 if it's going
to be colder than
60°F ( 16" C) before your next oil
change. When it's very cold, you should use
SAE
5W-30. These numbers on an oil container show its
viscosity, or thickness.

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. Refer to the
Maintenance Schedule
to determine when to change
your fluid. 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 dealership
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
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:
When outside temperatures are above 90°F (32°C).
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 (82°C
to
93 ” C).
Get the vehicle warmed up by driving about 15 miles
(24
km) when outside temperatures are above 50°F
(10°C). If it’s colder than 50°F (IOOC), you may have
to drive longer.
To check the fluid level
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).

or cloth.
NOTICE:
Be careful. A blow dryer or a heat lamp may
scorch the fabric.
Wipe with a clean cloth.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean off better with just
water and mild soap.
If you need
to use a solvent:
Gently scrape excess soil from the trim material
with
a clean, dull knife or scraper. Use very little
cleaner, light pressure and clean cloths (preferably
cheesecloth). Cleaning should start at the outside of
the stain, “feathering” toward the center. Keep
changing to a clean section
of the cloth.
When you clean a stain from fabric, immediately dry
the area with
a blow dryer to help prevent a cleaning
ring. (See the previous NOTICE.)
Special Cleaning Problems
Greasy or Oily Stains
Stains caused by grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar and asphalt can
be removed
as follows:
Carefully scrape off excess stain.
Follow the solvent-type instructions aescribed earlier.

specified
in Part D.
Body Lubrication
Lubricate all hinges and latches including those for the
body doors, hood, rear compartment, glove
box door,
console door and any folding seat hardware. Part
D tells
you what to use. More frequent lubrication may be
required when exposed to a corrosive environment.

When you are doing this check, the vehicle could
move suddenly. If it does, you or others could be
injured. Follow
the steps below.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake (see “Parking
Brake”
in the Index if necessary) and the regular brake.
NOTE: Do not use the accelerator pedal, and be
ready
to turn off the engine immediately if it starts.
3. Try to start the engine in each gear. The starter
should work only
in PARK (P) or NEUTRAL (N). If
the starter works in any other position, your vehicle
needs service.
