Engine Overheating
You will find the warning light about a hot engine on
your Buick instrument panel,
If you have the optional gage cluster, you may also have
a coolant temperature warning gage.
If Steam Is Coming From Your Engine:
CAUTION:
eam from an overheated engine can burn you
badly, even if you just open
the hood. Stay away
from
the engine if you see or hear steam coming
from
it. Just turn it off and get everyone away
From the vehicle until
it cools down. Wait until
there
is no sign of steam or coolant before
opening the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine
if it overheats, and get out of the vehicle until the
engine is cool. badly
damaged. The costly
covered by your warranty.
If No Steam Is Coming From Your Engine:
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too
hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
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. If you’re in a traffic jam, shift to “N” (Neutral).

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.

The coolant level should be at or above "FULL COLD.''
If it isn't, you may have a leak in the radiator hoses,
heater hoses, radiator, water

the cooling system,
I
/A CAUTION: 0
Heater and radiator hoses, and other engine
parts, can be very
hot. Don't touch them. If you p
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.
I
Engine damage from running your engine
without coolant isn't covered by your warranty.
If there seems to be no leak, check to see if the electric
engine 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
“FULL COLD,” 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.)
‘A CAUTION: Q
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 vbhicle’s coolant warning
system
is set for the properecoolant mix. With
plain water or the’wrong mix, your engine could
get too hot
but you douldn’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.
When the coolant in the coolant recovery tank is at or
above “FULL COLD,” 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.
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 radiatorpressure
cap, is hot. Wait for the cooling system and
radiator pressure
cap to cool if you ever have40
turn the pressure cap.
212

How to Add Coolant to the Radiator I
A@' #, I
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.
213

2. Then keep turning
the pressure cap,
but now push down
as you turn it.
Remove the
pressure cap.
I
3. Fill the radiator
with the proper
mix, up to the base
of the filler neck.
E
4. Then fill the coolant recovery tank to "FULL
COLD."
5. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap
off.
