radiator CHEVROLET BLAZER 1998 2.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine When you decide it’s safe to lift the hood, here’s what
you’ll see:
The coolant level should be at least up to the
ADD mark. i
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Fan
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else
until it cools down.
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.

Downloaded from www.Manualslib.com manuals search engine 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, start the engine again. See
if the engine cooling fan speed increases when idle
speed is doubled by pushing the accelerator pedal down.
If it doesn’t, your vehicle needs service. Turn off
the engine.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
ADD mark, add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL@ engine
coolant at the coolant recovery tank. (See “Engine
Coolant” in the Index for more information.)
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 mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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
50EO mixture of clean water and
DEX-COOL@ coolant.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
~~
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture. 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 coolant in the coolant recovery tank is at the
ADD mark, start your vehicle.
If the overheat warning continues, there’s one more
thing you
can try. You can add the proper coolant
mixture directly
to the radiator, but be sure the cooling
system is cool before you
do it.

Downloaded from www.Manualslib.com manuals search engine 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 radiator
pressure cap
-- even a little -- they can come out
at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap,
is hot. Wait for the cooling system and
radiator pressure cap to cool
if you ever have to
turn the pressure cap.
J- IW to Add Coolant to the Radiator
1. You can remove the pressure cap when the cooling
system, including the pressure cap and upper radiator
hose, is
no longer hot. Turn the pressure cap slowly
counterclockwise until
it first stops, (Don’t press
down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.

down as
you turn it. Remove the pressure cap.
3. Fill the radiator with the proper DEX-COOL@
coolant mixture, up to the base of the filler neck.
(See “Engine Coolant” in the Index
for more
information about the proper coolant mixture.)

5. Put the cap back on the coolant recovery tank, but
leave the pressure cap off.
6.
7.
Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the radiator
filler neck may be lower. If the level is lower, add
more of the proper
DEX-COOL@ coolant mixture
through the filler neck
until the level reaches the
base
of the filler neck.

The access door for the remote oil filter is in the steering
linkage shield assembly located under the radiator
support. Twist the screw to unlock or lock the door.
If you open the door, make sure it is securely closed
when you are finished.
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 To
remove the air cleaner, remove the wing nuts that
from the filter before disposal. Don’t ever dispose of oil
air
change your own oil, be sure to all free-flowing oil hold the cover on. Remove the cover and lift Out the
by putting it in the trash,-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 dealer, a service station or a local recycling
center for help. Insert a
new
air filter, then replace the air cleaner cow
Tighten the wing nuts to hold the cover in place. x.

Downloaded from www.Manualslib.com manuals search engine A 50/50 mixture of water and DEX-COOL@ coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F ( 129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.
NOTICE:
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.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half DEX-COOL@ coolant
which
won’t damage aluminum parts. If you use this mixture,
you don’t need to add anything else.
A 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 mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean water and
DEX-COOL@ coolant.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your
warranty. Too much water in the mixture 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 dealer check your cooling system.
I 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
When your engine is cold, the coolant level should be at
ADD, 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@
coolant mixture at the coolant recovery tank.
