coolant CHEVROLET BLAZER 1998 2.G User Guide

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.

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.

this procedure if coolant begins to flow out of the
filler neck, reinstall the pressure cap. Be sure the
arrows on the pressure cap line
up like this.
Engine Fan Noise
This vehicle has a clutched engine cooling fan. When
the clutch is engaged, the fan spins faster
to provide
more air to cool the engine.
In most everyday driving
conditions, the clutch is not engaged. This improves fuel
economy and reduces fan noise. Under heavy vehicle
loading, trailer towing and/or high outside temperatures,
the fan speed increases when the clutch engages.
So you
may hear an increase
in fan noise. This is normal and
should
not be mistaken as the transmission slipping or
making extra shifts. It is merely the cooling system
functioning properly. The fan will slow down when
additional cooling is
not required and the
clutch disengages.
You may also hear this fan noise when you start the
engine. It will go away
as the fan clutch disengages.

Downloaded from www.Manualslib.com manuals search engine Checking Things Under the Hood
' A CAUTION: I
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
or spill
things that will burn onto
a hot engine.
To open the hood, first pull
the handle inside the vehicle
on the lower driver's side
of
the instrument panel. Then
go to the front of the vehicle and release the
secondary
hood release.
Lift the hood, release the hood prop from its retainer and
put the hood prop into the slot in the hood.
You may
have a lamp that comes on when you lift the hood.
