1996 Oldsmobile Cutlass Supreme engine

NOTICE:
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
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 (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M, 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.
1 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 (orange-colored,
,
silicate-free) antifreeze.

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.

Chec'-'ng Coolant
When your engine is cold, the coolant level should be at
the
COLD mark or a little higher. When your engine. is
warm, the level should be up' to the HOT mark or, a
little higher.
/I .

this it conies on, it
means you're low

engine coolant.

Jfy& more coolant, add the proper mix at the. I
coolant recovery tank. I.
If the coolant recovery tank is. completely empty, add
,- ,coolant -to the radiator.. (See ,:'Engine Overheating" in-
the Index.) I'
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 doolant at the radiator.
Never turn the radiatol' pressure cap
-- even a
little.-- when the engine and radiator
are. hot.
I 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 s,pill coolant on a hot engme.

your brake system fixed, since a leak means that sooner
or later your brakes won’t work well, or won’t work
at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak. If you add fluid
when your linings are worn, then you’ll have too much
fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is
done on the brake hydraulic system. When your brake
fluid falls to a low level, your brake
warning light will come on. See “Brake System Warning
Light” in the Index.
What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No.’ 1052535). Use new brake fluid from a sealed
container only, and always clean the brake fluid
reservoir cap before removing
it.
A CAUTION:
-
If you have too much brake fluid, it can spill
on the engine. The fluid will burn if the engine
is hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work is done
on the brake
hydraulic system.
I A CAUTIC’J:
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work
at all. This could cause a
crash. Always use the proper brake fluid.

NOTICE:
0
0 Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index.

sound when the brake pads are worn
and new pads
are needed. The sound may come and go or
be heard
all the time your vehicle is moving (except when
you are pushing
on the brake pedal firmly).
..
The brake wear warning sound means’that
sooner or later your brakes won’t work well.
That could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly applied.
This does not mean something is wrong with your brakes.
Free movement
of brake calipers and properly torqued
wheel nuts are necessary to help prevent brake
pulsation. When tires are rotated, inspect brake calipers
for movement, brake pads for wear, and evenly torque
wheel nuts in the proper sequence to
GM specifications.
Brake linings should always be replaced
as complete
axle sets.
