How ,to Add Fluid Engine Coolant
I
Refer to the Maintenance Schedule to determine what
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.
~ kind of transaxle fluid to use. See “Recommended ,
1. Pull out the dipstick.
.2. 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 ove@ZZ. We recommend you use only
fluid labeled DEXRON@-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.”
0 When the correct fluid level is obtained, push the
dipstick back in all the way.

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 Oldsmobile 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.
0 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
DEX-COOL (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant 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.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half DEX-COOL
TM (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use
this mixture, you don’t need to add anything else.
1 CAUTION:
- -
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 50/50 mix of clean
water and DEX-COOL (orange-colored,
,
silicate-free) antifreeze.
6-21

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 retailer 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.

Chec'-'ng 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.

If the coolant recovery tank is. completely empty, add

the Index.) I'
A CAUTION:
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 doolant at the radiator.
Never turn the radiatol' pressure cap
-- even a
little.-- when the engine and radiator
are. hot.
I Add coolant mix at the recovery tank, but be careful not
to
spill it.
I A CAUTION:
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 s,pill coolant on a hot engme.

Open the cap labeled WASHER FLUID ONLY. Add
washer fluid until the tank is full. Brakes
Brake Fluid
When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system.
Also,
water doesn’t clean as well as washer fluid.
Fill your washer fluid tank only
three-quarters full when it’s very cold. This
allows for expansion, which could damage
the tank
if it is completely full.
Don’t use radiator antifreeze in your
windshield washer.
It can damage your
washer system and paint.

There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the brake
fluid goes down to an acceptable level during normal
brake lining wear. When new linings are put in, the fluid
level goes back up. The other reason is that fluid
is
leaking out of the brake system. If it is, you should have

Part ,. C : Periodic, Maintenance
Inspections
Listed below are inspections and services which should
be performed at least twice a year (for instance, each
spring and fall). You should let your GM retailer’s
service department or other qualified service center do
these jobs. Make sure any necessary repairs
are
completed at once.
‘Proper procedures to perform these services may )be
found in a Oldsmobile Service Manual. See “Service
and Owner Publications’’ in the Index.
Steering, Suspension and Front-Wheel-Drive
~ Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
.near the exhaust system. Look for broken, damaged, missing or out-of-position parts
as well as open seams,
holes, loose connections or other conditions which could
cause a heat build-up in the floor pan or could let
exhaust fumes into the vehicle.
See “Engine Exhaust” in
the Index.
Radiator and Heater Hose Inspection
Inspect the hoses and have hem replaced if they are
cracked, swollen or deteriorated. Inspect
all pipes,
fittings and clamps; replace as needed.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and for damage or missing parts. Replace parts as
needed. Replace any cables that have high effort or
excessive wear.
Do not lubricate accelerator and cruise
control cables.
Brake System Inspection
Inspect the corfiplete system. Inspect brake lines and
hoses for’ proper hook-up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. Check parking
brake adjustment. You may need to have your brakes
inspected more often if your driving habits or conditions
result .in frequent braking.
