engine coolant CHEVROLET CAVALIER 1997 3.G User Guide

Downloaded from www.Manualslib.com manuals search engine If the coolant inside the coolant surge tank is boiling,
don’t
do anything else until it cools down.
The coolant level should be at the
FULL COLD line.
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.
A CAUTION:
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.
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 fan is running.
If the engine is
overheating, the fan should be running.
If it isn’t, your
vehicle needs service.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
FULL COLD mark, 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.

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@coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
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.

when the cooling system, including the coolant surge
tank pressure cap
and upper radiator hose, is no
longer hot.
Turn the pressure cap slowly about
one-quarter turn to
the left and then stop.
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.
2. Then keep turning the
pressure cap slowly, and
remove it.

up to the FULL COLD mark.

4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch
out for the
engine fan.
By this time, the coolant level inside the coolant
surge tank may be lower.
If the level is lower, add
more of the proper mix to the coolant surge tank
until the level reaches the FULL COLD mark.

To open the hood,
first pull the handle
inside the vehicle. A CAUTION:
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.

that rn can get on hot t jne 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 or spill
things that will burn onto a hot engine.

You do not need to check the fluid level unless you
suspect
a clutch problem. To check the fluid level, take
the cap
off. If the fluid reaches the step inside the
reservoir, the fluid level
is correct.
Engine Coolant
The cooling system in your vehicle is filled
with 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@ 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 DEX-COOL@ coolant will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 “F (129°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:
I
When adding coolant, it is important that you
use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than
DEX-COOL’ 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. Damage caused by the use of coolant
other than
DEX-COOL@ is not covered by your
new vehicle warranty.
