NOTICE:
When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
0 Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to
freeze and damage your washer fluid tank
and other parts of the washer system.
Also,
water doesn’t clean as well as washer fluid.
Fill your washer fluid tank only 314 full
when it’s very cold. This allows for
expansion, which could damage the tank
if
it is completely full.

If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. Try to keep your engine under load (in a drive gear
where the engine runs slower).
If
you no longer have the overheat warning, you can drive.
Just to be safe, drive slower for about
ten minutes. If the
warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see if the
warning stops. But then, if you still have the warning,
TURN OFF THE ENGINE AND GET EVERYONE
OUT OF THE VEHICLE until it cools down.
You may decide not
to lift the hood but to get service
help right away. When you
decide it’s safe to lift
the hood, here’s what
you’ll see:
0 Coolant recovery tank
0 Radiator pressure cap
0 Electric engine fan
ProCarManuals.com

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
“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.
I NOTICE:
I
Engine damage from running your engine
without
coolant isn’t covered by your warranty. I
If there seems to be no leak, check to see if the electric
engine fan is running.
If the engine is overheating, the
fan should be running.
If it isn’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 “COLD” mark, 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.)
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts. Use
the recommended coolant.

I 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.
When the coolant in the coolant recovery tank is at or
above the
“COLD” 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.
A 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
pressure cap
-- even a fittle -- they can come out
at
high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is
hot.
CAUTION: (Continued)
CAUTION: (Continued)
Wait for
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
NOTICE:
Your engine has a specific radiator fill procedure.
Failure to follow this procedure could cause your
engine to overheat and
be severely damaged.
. ..,
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.
2.
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.
Then keep turning the pressure cap, but now push
down as you turn
it. Remove the pressure cap.

4. Fill the radiator with the proper
mix, up to the base
of the filler neck.
.,
If you see a stream of coolant coming from an air
bleed valve, close the valve. Otherwise, close the valve(s) after the radiator
is filled.
5. Rinse or wipe any spilled coolant from the engine
and compartment.

6. Then fill the coolant recovery tank to “COLD.”
7. Put the cap back on the coolant recovery tank, but
leave
the radiator pressure cap off.
A
8. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine
fan( s).
9. By this time the coolant level inside the radiator
filler neck may
be lower. If the level is lower, add
more of the proper mix through the filler neck
until
the level reaches the base of the filler neck.

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 or if you need to add coolant to your
radiator, see “Engine Overheating” in the Index.
The proper coolant for your Buick will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 262°F (128°C).
Protect against rust and corrosion.
0 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-M,” 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.
If you use this mixture, you don’t need to add
anything else.
NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The repair cost wouldn’t be covered by your
warranty. Too much water in the mix can freeze
‘and crack the engine, radiator, heater core and other parts.
