Engine Coolant Heater (Option)
In very cold weather,
0°F (-1 8°C) or colder,
the engine coolant
heater can help. You’ll
get easier starting and
better fuel economy
during engine warm-up.
Usually, the coolant heater should be plugged
in a
minimum of four hours prior to starting your vehicle.
To Use the Coolant Heater
I. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
Plugging the cord into an ungrounded outlet
could cause an electrical shock.
Also, the wrong
kind
of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.
4. After you’ve used the coolant heater, be sure to store
the cord as it was before to keep it away from moving
engine parts.
If you don’t, it could be damaged.
How long should
you keep the coolant heater plugged
in? The answer depends on the outside temperature,
the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your Buick dealer
in the area where you’ll be parking
your vehicle. The dealer can give you the best advice for
that particular area.

Anti-Lock Brake System Active Light
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
the anti-lock brake system
active light will come on.
Engine Coolant Temperature Light
-
TEMP
This light tells you that your
engine coolant has
overheated or your radiator
cooling fan
is not working.
Slippery road conditions may exist if this light comes
on,
so adjust your driving accordingly. The light will
stay on for
a few seconds after the system stops
adjusting brake pressure,
The anti-lock brake system active light
also comes on
briefly when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
there to tell you when the system is active. If
you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine
as soon as possible.
In “Problems
on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

Engine Coolant Temperature Gage

TEMPERATURE
You have a gage that shows
the engine coolant temperature. If the gage
pointer moves into the red
area, your engine is too hot!
That reading means the same thing as the warning light. It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull
off the road, stop your
vehicle and turn
off the engine as soon as possible.
In “Problems on the Road,”
this manual shows what to
do. See “Engine Overheating” in
the Index.
Low Coolant Warning Light
LOW
COOLANT
If this light comes on, your
system is low on coolant
and the engine may
overheat. See “Engine
Coolant” in ‘the Index and
have your vehicle serviced as soon as you can.

Heating
On cold days, use HTR with the temperature lever all
the way to
WARM. The system will bring in outside air,
heat it and send it
to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it’s
cold outside
(0°F (-18°C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” in the Index.
Ventilation System
Adjust the direction of airflow by moving the
louvered vents.
Your vehicle’s flow-through ventilation system supplies
outside air into the vehicle when
it is moving. Outside
air will also enter the vehicle when the air conditioning
fan
is running.

Engine Overheating
YOU will find a coolant temperature gage and a warning
light about a hot engine on your instrument panel. See
“Engine Coolant Temperature Gage” and “Engine
Coolant Temperature Warning Light” in the Index.
You also have a LOW COOLANT warning light on
your instrument panel. See “Low Coolant Light” in
the Index.
If Steam Is Coming From Your Engine
Steam 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.

NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
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:
I. 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 NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@) or
THIRD
(3).
If you no longer have the overheat warning, you can drive.
Just to be safe, drive slower for about
10 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 ofSthe 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.
ProCarManuals.com

When you decide it’s safe to lift the hood, here’s what
you’ll see:
3.1L L82 (Code M) Engine
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Electric Engine Fans
r R:
3.8L L36 (Code K) Engine
An electric 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 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.
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.
I 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 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 the COLD 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 information.)
I
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.
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.
