1997 OLDSMOBILE CUTLASS engine coolant

Engine Overheating
You will find a coolant temperature gage on your
Oldsmobile’s instrument panel. See “Engine Coolant
Temperature Gage” in the Index.
You will also find a
low coolant level warning light on your Oldsmobile’s
instrument panel. See “Low Coolant Warning Light”
in the Index.
If Steam Is Coming From Your Engine
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine
if’ you see or hear steam coming
from it. Just turn it
off and get everyone away
from the vehicle until it cools down. Wait until
there
is no sign of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You
or others could be badly burned. Stop your
engine if
it overheats, and get out of the vehicle
until the engine is cool.
I NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.

Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
An electric fan under the hood can start up even
when the engine
is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don’t do anything else until it cools down.

B. Electric engine fans

The 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. 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 fans are running.
If the
engine
is overheating, both fans should be running. If
they aren’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 TM 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.)
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.

I
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.

NOTICE:
If you need a new cap, be sure to get the right
type. Your retailer can get one
for you. If you get
the wrong type, it may not fit properly. This may
cause your malfunction indicator lamp to light and your fuel tank and emissions system may be
damaged. See “Malfunction Indicator Lamp” in
the Index.
Checking Things Under the Hood
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. 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
OF spill
things that will burn onto a hot engine.
The following sections tell you how to check fluids,
lubricants and important parts under the hood.
Hood Release
To open the hood, first pull
the hood release handle
inside the vehicle.
ProCarManuals.com

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.
