cooling Oldsmobile Cutlass 1998 s User Guide

1 I
NOTICE:
We recommend you use only fluid labeled
DEXRON@-III, 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.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
J
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.
A 50/50 mixture of water and DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 OF (1 29 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
only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL 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. Damage caused by the use
of coolant other than DEX-COOL@
is not
covered by your new vehicle warranty.
6-18

What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL@ coolant which
won’t damage aluminum
parts. If you use this mixture,
you don’t need to add anfthing else.
Adding only plain water to your coorrng system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture
will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean water and
DEX-COOL@ coolant.
NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty. Too much water
in the mixture 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.
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.

Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM original
equipment parts.
This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your
Oldsmobile model.
I
Using the wrong -)la( nent wheels, wk 1.
bolts or wheel nuts on your vehicle can be
dangerous.
It could affect the braking and
handling of your vehicle, make your tires lose air
and make you lose control. You could have a
collision in which you or others could be injured.
Always use the correct wheel, wheel bolts and
wheel nuts for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer
or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for
more information.
Used Replacement Wheels
Putting
a used wheel on your vehicle is
dangerous. You can’t know how it’s been used or
how far it’s been driven. It could
fail suddenly
and cause an accident.
If you have to replace a
wheel, use a new
GM original equipment wheel.

Maintenance Schedule
I Short TripKity Definition I
Follow the Short TripKity Maintenance Schedule if any
one of these conditions
is true for your vehicle:
0 Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as fiequent
driving in stop-and-go traffic).
0 Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier on top of
your vehicle.
If the vehicle is used for delivery service, police, taxi
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down soonex
or other commercial application.
