1996 CHEVROLET BLAZER engine coolant

Downloaded from www.Manualslib.com manuals search engine L
The coolant level should be at the ADD 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. 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 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.

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 TM
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant”
in the Index for
more kformation
)
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 TM antifreeze.
1 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 mix.

YOL -an 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
ADD, start your vehicle.
If the overheat warning continues, there’s one more
thing
you can try. You can add the proper coolant mix
directly to the radiator, but be sure the cooling system is
cool before
you do it.

at high speed. Never turn the cap when the
cooling system, including the radiator pressure

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.
2. Then keep turning the pressure cap, but now push
down
as you turn it. Remove the pressure cap.
