engine coolant OLDSMOBILE SILHOUETTE 1997 Owner's Manual

L
NOTICE:
When adding coolant, it is important that you
use
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
TM (silicate-free)
antifreeze which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. 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 (silicate-free) antifreeze.

I 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.
Checking Coolant
The engine coolant reservoir is located on the urlver s
side of the vehicle, above the air cleaner.
When your engine is cold, the coolant level should be
at
FULL COLD, or a little higher. When your engine is
warm, the level should be up to FULL HOT, or a
little higher.

Adding Coolant
If you need more coolant, add the proper DEX-COOL"
mix ut the coolant recovery tmk.
A CAUTION:
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn
you badly.
With the coolant recovery tank, you will almost
never have to add coolant at the radiator. Never turn the radiator pressure cap
-- even a
little
-- when the engine and radiator are hot.
Add coolant
mix at the recovery tank, but be careful not
to spill
it.
I 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.

Radiator Pressure Cap Power Steering Fluid
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. The power steering fluid reservoir
is located
to the right
of the windshield washer fluid reservoir, at the back of
the engine compartment.

Underhood Fuse and Relay Center
This fuse and relay center is located in the engine
compartment, in front
of the windshield washer
fluid reservoir.
The fuses marked spare are available
if a replacement
fuse is needed.
