1993 BUICK CENTURY cooling

I
The coolant level should be at or above the “FULL
HOT” 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.
1 [ 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.
If there seems to be no leak, check to see if the electric
engine
f8n is running. If the engine is overheating, the f8n
should be running. If it isn’t, your vehicle needs service. \
How to Add Coolant to the Coolant Recovery lhnk
If you haven’t found a problem yet, but the coolant level
isn’t at or above
“ADD:’ add a 50/50 mixture of clean
water (preferably distilled) and a proper antifreeze at the
coolant recovery
tank. (See “Engine Coolant” in the
Index for more information about the proper coolant
mix.)

All Cooling Systems
A CAUTION:
Adding only plain water to your c.ooling 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 a proper
antifreeze.

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. I

When the coolant in the coolant recovery tank is at or
above
the “FULL HOT” mark, 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.
I
/i CAUTION:
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
pllessure cap--even a little-they can -me
out at hlgh speed. NeAler turn the cap when
the cwllng qstern, Including the radiator
pressure
cap, is hot. Wait tor the cooling
system and radiator pressure cap to cool if you
ever have to turn the pressure cap.

How to Add Coolant to the Radiator
F
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 to
the left 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. I

Engine 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. \
The proper coolant for your Buick will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262” F (128” C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
What to Use: Use a mixture of one-half clean water
(preferably distilled) and one-half antifreeze that meets
“GM Specification 1825-Mi’ which won’t damage
aluminum parts. You can also use a recycled coolant
conforming to GM Specification 1825-M with a complete
coolant flush
and refill. Use GM Engine Coolant
Supplement
(sealer) with any complete coolant change. If
you use these, you don’t need to add anything else.
