When the coolant in the coolant
recovery tank is at or above the
FULL
HOT mark, start your vehicle.
If the overheat warning continues,
there’s one more thing you can try.
You
can add the proper coolant mix directly
to the radiator, but be sure the cooling
system is cool before you do it.
How to Add Coolant to the
Radiator:
1. You can remove the radiator pressur(
cap when the cooling system,
including the radiator pressure cap
and upper radiator hose, is no longer
hot. Turn the pressure cap slowly to
the left until it first stops. (Don’t
press down while turning the
pressure cap.) If you hear a hiss, wail
for that to stop.
A hiss means there i:
still some pressure left.

2. Then keep turning the pressure cap,
but now push down as you turn
it.
Remove the pressure cap.
3. Fill the radiator with the proper mix,
up to the base of the filler neck.
I. Then fill the coolant recovery tank to
the
ADD mark.

5. Put the cap back on the coolant
recovery tank, but leave the radiator
pressure cap off. 6. Start the engine and let it run until
you can feel the upper radiator hose
getting hot. Watch out for the engine
fan.
7. By this time the coolant level inside
the radiator filler neck may be lower.
If the level is lower, add more of the
proper
mix through the filler neck
until the level reaches the base
of the
filler neck.
8. Then replace the pressure cap. At an!
time during this procedure
if coolant
begins to
flow out of the filler neck,
reinstall the pressure cap. Be sure tht

NOTICE:
If you use oils that do not have
either the “starburst” symbol or an
API SH or SG designation, you can
cause engine damage not covered
by your warranty.
GM Goodwrench@ oil (in Canada, GM
Engine Oil) meets all the requirements
for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your
Oldsmobile dealer is ready to advise
if
you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles (6
It’s below freezing outside and most
trips are less than
10 miles (16 km) .
The engine is at low speed most of the
time (as in door-to-door delivery, or in
stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
The vehicle is frequently operated off-

Engine Coolant Heater (Engine Block Heater)
An engine coolant heater can be a big
help if you have to park outside in very
cold weather,
0°F (-18°C) or colder. If
your vehicle has this option, see Engine
Coolant Heater
in the Index.
What to Do with Used Oil
Did you laow that used engine oil
contains certain elements that may be
unhealthy for your skin and could even
cause cancer? Don’t let used oil stay on
your skin for very long. Clean your skin
and nails with soap and water, or a
good hand cleaner. Wash or properly
throw away clothing or rags containing
used engine oil. (See the manufacturer’s
warnings about the use and disposal of
oil products.)
Used oil can be a real threat to the
environment.
If you change your own
oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t
ever dispose of oil by putting it in the
trash, pouring it on the ground, into
sewers, or into streams or bodies
of
water. Instead, recycle it by taking it to a
place that collects used oil.
If you have a
problem properly disposing of your used
oil, ask your dealer, a service station or a
local recycling center for help.

What to Use
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets
“GM Specification
6038-M,” which won’t damage
aluminum parts. If you use this mixture,
you don’t need
to add anything else.
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.
Some conditions, such as air trapped in
the cooling system, can affect the
coolant level in the radiator. Check the
coolant level when the engine is cold
and follow the steps under
Adding
Coolant for the proper way to add
coolant.
If you have to add coolant more than
four times a year, have your dealer
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.
~~
Adding Coolant
To Check Coolant
When your engine is cold, the coolant
level should be at
ADD, or a little
higher. When your engine is warm, the
level should be up to
FULL HOT, or a
little higher.

To Add Coolant
If you need more coolant, add the proper
mix
at the coolant recovery tank.
Add coolant mix at the recovery tank,
but be careful not
to spill it.
I Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi
(105 1tPa) pressure-type cap and
must be tightly installed
to prevent
coolant
loss and possible engine
damage from overheating. Be sure
the arrows on the cap line up with
the overflow tube
on the radiator
filler neck.
When you replace your radiator
pressure cap, an AC@ cap
is
recommended.
Thermostat
Engine coolant temperature is
controlled by a thermostat in the engine
coolant system. The thermostat stops
the flow
of coolant through the radiator
until the coolant reaches a preset
temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.

with a clean rag. Replace the cap and
completely tighten it. Then remove the
