4ir Cleaner
To remove the air cleaner,
open both clamps and push
the rear of the air cleaner
toward the rear
of the
engine compartment.
Insert
a new filter. Then replace the air cleaner
assembly, making certain the
PVC air tube is properly
seated
in the left hand valve cover and the clamps are
securely fastened.
Refer to the Maintenance Schedule
to determine when to
replace the air filter.
See “Scheduled Maintenance Services”
in the Index.
I
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.
I 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 Transmission Fluid
When to Check and Change
A good time to check your automatic transmission 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:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
0 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 Oldsmobile retail
facility 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.
I NOTICE:
- ~~
Too much or too little fluid can damage your
transmission.
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
transmission fluid.
Wait at least 30 minutes before checking the
transmission 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.
0 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).
ProCarManuals.com

Then, without shutting off the engine, follow these steps:
1. Flip the handle up and then 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 COLD area for a
cold check or in the HOT area or cross-hatched area
for a hot check.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the
way; then flip the handle
down to lock the dipstick in place.

Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(I 0 000 to 13 000 km) for any signs of unusual wear.
If unusual wear is present, rotate your tires as soon
as
possible and check wheel alignment. Also check for
damaged tires or wheels. See “When It’s Time for New
Tires” and “Wheel Replacement” later
in this section for
more information.
The purpose of regular rotation
is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals. When rotating your tires,
always use the correct rotation
pattern shown here.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the CertificatiodTire
label. Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque”
in the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come off and cause
an accident. When you change
a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use
a cloth or a paper towel to do this; but be
sure to use a scraper
or wire brush later, if you
need to, to get all the rust or dirt off. (See
“Changing
a Flat Tire” in the Index.)

Vacuum and brush the area to remove any
loose dirt.
Always clean a whole trim panel or section. Mask
surrounding trim along stitch or welt lines.
Mix Multi-Purpose Powdered Cleaner following
the directions on the container label.
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.
Then dry it immediately with a blow dryer.
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.
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:
1. Carefully scrape off excess stain.
2. Follow the solvent-type instructions described earlier.
3. Shoe polish, wax crayon, tar and asphalt will stain if
left
on a vehicle’s seat fabric. They should be removed
as soon as possible. Be careful, because the cleaner
will dissolve them and may cause them to spread.

Don’t use cleaning agents that are petroleum based,
or that ‘contain acid or abrasives. Ail cleaning agents.
should be flushed promptly and not allowed to‘dry on
the surface,
or they could stain. Dry the finish with a
soft,clean chamois,.or a
100% cotton towel to avoid
surface scratches and water spotting.
High pressure car washes may cause water to enter
your vehicle.
I
Finish Care
Occasional waxing or mild polishing ,of your
Oldsmobile by hand may be necessary
to remove
,residue from the paint finish.
You can get GM-approved
.
I. ..
-.
,. .-
cleaning products from your retailer. (See “Appearance
Care and MateAals” in the Index..)
Your Oldsmobile has a “basecoatlciearcoat” paint finish. The
clearcoat gives more depth and gloss to the colored basecoat.
.
Always use wakes and polishes that are non-abrasive and
made for a basecoatlclearcoat paint finish.
I
NOTICE:
Machine compounding or aggressive polishing on
a basecoatlclearcoat paint finish may dull the
finish or leave swirl marks.
-I
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc., can
.
damage your vehicle’s finish if they remain on painted
surfaces. Wash the vehicle as soon as possible.
If
necessary, use non-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.
,
Exterior painted surfaces are subject to aging, weather
and chemic.al fallout that can take their toll over a period
of years.
You can help to keep the, paint finish looking
new by keeping your Oldsmobile garaged or covered
whenever possible.

Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water
is all that is usually
needed. However, you may use
GM Chrome Polish
on chrome or stainless steel trim,
if necessary.
Use special care with aluminum
trim. To avoid
damaging protective trim, never use auto or chrome
polish, steam or caustic soap to clean aluminum.
A
coating of wax, rubbed to high polish, is recommended
for all bright metal parts.
Aluminum Wheels
Keep your wheels clean using a soft clean cloth with
mild soap and water. Rinse with clean water. After
rinsing thoroughly, dry with a soft clean towel. A wax
may then be applied.
The surface
of these wheels is similar to the painted
surface
of your vehicle. Don’t use strong soaps,
chemicals, abrasive polishes, abrasive cleaners or
abrasive cleaning brushes on them because you could
damage the surface.
Don’t take your vehicle through an automatic car wash
that has silicon carbide tire cleaning brushes. These
brushes can also damage the surface
of these wheels.
Tires
To clean your tires, use a stiff brush with a tire cleaner.
I NOTICE:
When applying a tire dressing always take care to
wipe off any overspray or splash from all painted
surfaces
on the body or wheels of the vehicle.
Petroleum-based products may damage the
paint finish.
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.
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 retailer or other service
outlets. Larger areas of finish damage can be corrected
in your retailer’s body and paint shop.
