1998 CHEVROLET VENTURE coolant

When you decide it’s safe to lift the hood, here’s what
rou’ll see:
i. Radiator Pressure Cap
3. Electric Engine Fans
3. Coolant Recovery Tank
A CAUTION:
I
An electric engine cooling 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 recovery tank is boiling,
don’t
do anything else until it cools down.

The coolant level should be at or above the
FULL COLD mark.
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 cooling 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
Recovery Tank
If you haven’t found a problem yet, but the coolant
level isn’t
at or above the FULL COLD 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.)
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.

I 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.
a
I ,A CAU I ION:
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 or
above the
FULL COLD 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.

How to Add Coolant to the Radiator
2. Then keep turning the pressure cap, but now push
down as you turn
it. Remove the pressure cap.
1.
You can remove the radiator pressure cap when the
cooling system, including the radiator 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.

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.)

4. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fans.
5. 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.

6. Then replace the pressure cap. At any time during
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.
