coolant Oldsmobile Achieva 1997 s User Guide

If the coolant inside the coolant surge tank is boiling,
don’t do anything else until
it cools down.
Lne coolant level should be at or above
FULL COLD.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump
or somewhere else in
the cooling system.
J AUTION:
Heater and radiator hoses, and other engine
parts, can be
very hot. Don’t touch them. If you
do, you can be burned.
Don’t run the engine if there is
a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
I NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see
if the electric engine fan is running. If the engine is
overheating, the
fan should be running. If it isn’t, your
vehicle needs service.

How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD, add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL@ coolant at
the coolant surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap,
is cool
before you do
it. (See “Engine Coolant” in the Index for
more information.)
A CAUTIOP
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the coolant
surge tank pressure cap
-- even a little -- they
can come out at high speed. Never turn the cap
when the cooling system, including the coolant
surge tank pressure cap,
is hot. Wait for the
cooling system and coolant surge tank pressure
cap
to cool if you ever have to turn the
pressure cap.

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

1. You can remove the coolant surge tank pressure cap
when the cooling system, including the coolant surge
tank pressure cap and upper radiator hose,
is no
longer hot. Turn the pressure cap slowly about
one-quarter turn to the left and then stop.
If you hear
a hiss, wait for that to stop. A hiss means
there is still some pressure left.
2. Then keep turning the pressure cap slowly, and
remove it.
5-19

3. Then fill the coolant surge tank with the proper mix,
up to FULL COLD, or just above the small cylinder
at the base
of the opening.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until
you can feel the upper
radiator hose getting hot. Watch out for the
engine fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more
of the proper mix to the coolant surge tank
until the level reaches
FULL COLD, or just above
the small cylinder at the base
of the opening.

Here you will find information about the care of your Oldsmobile. This section begins with service and fuel
information, and then it shows how to check important fluid and lubricant levels. There is also technical information
about your vehicle, and a part devoted

Checking Things Under the Hood
I A CAU'I :
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
A CAU JON:
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that will burn onto
a hot engine.

When to Check and What to Use
Refer to the Maintenance
Schedule to determine how
often you should check the
fluid level
in your clutch
master cylinder reservoir
and for the proper fluid.
See “Owner Checks
and Services” and
“Recommended Fluids and
Lubricants” in the Index.
How to Check
If you can see fluid in the reservoir, the level is acceptable.
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@ 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 50150 mixture of water and the proper coolant for
your Oldsmobile will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
