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
TM coolant.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
c
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 spill coolant on a hot engine.

Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss. If a
leak occurs, take the vehicle to your Oldsmobile retail
facility Service Department and have it repaired as soon
as possible. You may also have your fluid level checked
by your retailer or service center when you have your
oil changed.
Engine Coolant
The cooling system in your vehicle is filled with new
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
TM extended life 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.
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 “F (129 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL TM (silicate-free) coolant.
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” coolant which
won’t damage aluminum parts. If you use this mixture,
you don’t need to add anything else.
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 TM coolant.
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:
I I
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.
