Engine Coolant
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. \
The proper coolant for your Buick will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262” F (128” C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
What to Use: Use a mixture of one-half clean water
(preferably distilled) and one-half antifreeze that meets
“GM Specification 1825-Mi’ which won’t damage
aluminum parts. You can also use a recycled coolant
conforming to GM Specification 1825-M with a complete
coolant flush
and refill. Use GM Engine Coolant
Supplement
(sealer) with any complete coolant change. If
you use these, you don’t need to add anything else.
I
A CAUTION:
Adding only plain water to your coollng system
can
be dangerous. Plain water, or some other
liquid
like alcohol, can boil before the proper
coolant mix will. Mur vehicle’s coolant
warning system
Is set for the proper coolant
mix. With plain water or the wrong mlx, your
engine could get too hot but you wouldn’t get
the overheat warning. bur engine could catch
fire and you or others’could be burned. Use a
50/50 mPx of clean water and a proper
antifreeze.

Using Foam-Qpe Cleaner on Fabric
Vacuum and brush the area to remove any loose dirt.
Always clean a whole trim panel or section. Mask
Mix Multi-Purpose Powdered Cleaner following the
Use suds only and apply with a clean sponge.
Don’t saturate the material.
Don’t rub it roughly.
As soon as you’ve cleaned the section, use a sponge to
remove the suds.
Rinse the section with a clean, wet sponge.
Wipe off what’s left with a slightly damp paper towel

or cloth.
or a heat lamp.
Wipe with a clean cloth.
Using Solvent=Qpe 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 it, then:
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 an air hose, hair dryer, or heat lamp to
help prevent a cleaning ring. (See the previous
NOTICE.)

Special Cleaning Problems
Greasy or Oily Stains: Like grease, oil, butter,
margarine, shoe polish, coffke with cream, chewing gum, cosmetic creams, vegetable
oils, wax crayon, tar
and asphalt.
Carefully scrape off excess stain.
Then follow the solvent-type instructions above.
Shoe polish, wax crayon, tar and asphalt will stain if
left on
a vehicle seat fabric. They should be removed as
soon as possible. Be careful, because the cleaner will
dissolve them and may cause them to bleed.
Non-Greasy Stains: Like catsup, coffee (black), egg,
fruit, fruit juice,
milk, soft drinks, wine, vomit, urine
and
blood.
Carefully scrape off excess stain, then sponge the soiled
area with cool water.
If a stain remains, follow the foam-type instructions
above.
If an odor lingers after cleaning vomit or urine, treat
the area
with a watedbaking soda solution: 1 teaspoon
(5 ml) of baking soda to 1 cup (250 ml) of lukewarm
water.
Finally, if needed, clean lightly with solvent-type
cleaner.
Combination Stains: Like candy, ice cream,
mayonnaise, chili sauce and unknown
stains.
Carefully scrape off excess stain, then clean with cool
If a stain remains, clean it with solvent-type cleaner.
Cleaning Vinyl
Just use warm water and a clean cloth. water and allow to dry.
Rub with a
clean, damp cloth to remove dirt. You may
have to do it more than once.
Things like tar, asphalt and shoe polish will stain if you
don't get them
off quickly. Use a clean cloth and
solvent-type vinyl/leather cleaner.
Cleaning the Top of the Instrument Panel
Use only mild soap and water to' clean the top surfaces of
the instrument panel. Sprays containing silicones or
waxes may cause annoying reflections
in the windshield
and even make it difficult to see through the windshield
under certain conditions.

Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to the parts repaired or
replaced to restore corrosion protection.
Foreign Material
Calcium chloride and other salts, ice melting agents, road
oil and tar, tree sap, bird droppings, chemicals from
industrial chimneys, and other foreign matter can damage
your vehicle’s finish if they remain on painted surfaces. Use cleaners that are marked safe for painted surfaces for
these stains.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches
can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas of finish damage can be corrected in
your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these
are not
removed, accelerated corrosion (rust) can occur on the
underbody parts such as fuel lines, frame,
floor pan, and
exhaust system even though they have corrosion
protection.
At least every spring, flush these materials from the
underbody
with plain water. Clean any areas where mud
and other debris can collect. Dirt packed
in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody vehicle washing system can
do this for you.
Chemical paint Spotting
Some weather and atmospheric conditions can create a
chemical fdlout. Airborne pollutants can
f$ll upon and
attack painted surfaces on your vehicle. This damage can
take
two forms: blotchy, ringlet-shaped discolorations,
and small irregular dark
spots etched into the paint
surhce.
Although no defect in the paint job causes
this, Buick
will repair, at no charge to the owner, the surfaces
of new
vehicles damaged by this fallout condition within 12
months or 12,OOO miles (20 OOO km) of purchase,
whichever comes first.
