1995 OLDSMOBILE SILHOUETTE coolant

Engine Oil Additives
Don’t add anything to your oil. Your Oldsmobile retailer
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 5 to 10 miles (8 to 16 krn).
This
is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving
in stop-and-go traffic).
Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier 011 top of
your vehicle.
If any one
of these is true for your vehicle, then you
need to change your oil and filter every
3,000 miles
(5 000 km) or 3 months -- whichever comes first.
If none
of them is true, change the oil and filter every
7,500 miles (12 500 km) or I2 months -- whichever
comes first.
Engine Coolant Heater (Option)
An engine coolant heater can be a big help if you have
to park outside
in very cold weather, 0°F (- 18OC) or
colder.
If your vehicle has this option, see “Engine
Coolant Heater”
in the Index.
What to Do with Used Oil
Did you know 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 or by 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 retailer, a service station or a local recycling
center for help.

Engine 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.
The proper coolant for your Oldsmobile
will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 262 OF ( 128 ” C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use
Use a mixture of one-half clean water (preferably
distilled)
and one-half antifreeze that meets “GM
Specification
1825M,” which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant flush and refill.
If you use
this mixture,
you don’t need to add anything else.
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.

Adding Coolant
The engine coolant reservoir is located on the
passenger’s side
of the vehicle, towards the middle of
the engine compartment.
3.1L V6: Checking Coolant
3800 V6: Checking Coolant
To Check Coolant
When your engine is cold, the coolant level should be at
COLD, 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
cnolclnt recoverv tank.
Add coolant mix at the recovery tank, but be careful not
to spill it.
Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi (105 kPa)
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.
