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:
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.
