heater BUICK CENTURY 1996 Owners Manual

NOTICE:
Your engine is designed to work with the
electronics in your vehicle.
If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer.
If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of
this manual that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle’’ in the Index.
Engine Coolant Heater (Option)
In very cold weather, 0” F (-‘18 O C) or colder, the engine
coolant heater can help. You’ll get easier starting and
I
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.

10 use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC 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.

When outside temperatures are cold, sliding the upper
lever to HEATER and the lower lever to HOT will
send heated air through the heater ducts, and some
through the defroster vents. VENT and
HEATER
are labeled ECONOMY positions because the air
conditioner compressor doesn't run
in these two
settings. This reduces engine load, resulting in
improved fuel economy. If either setting fails to keep
you comfortable, or causes your windows to fog up,
slide the upper lever to one
of the air conditioning
positions, or to DEF (defrost).
The
upper lever has three air conditioner settings. On
very hot days, open the windows long enough to let hot,
inside air escape. This reduces the amount
of work your
air conditioner's compressor will have
to do, which
should help fuel economy.
MAX: Provides maximum cooling with the least
amount
of work. This setting recirculates much of the
air inside your vehicle
so it maximizes your air
conditioner's performance and fuel economy.
NORM: Use for normal cooling on hot days. This
setting cools outside air and directs it through the
instrument panel outlets.
BI-LEV: Use this on cool, but sunny days. This setting
brings
in the outside air, and directs it in two ways. The
cool air is directed to the upper portion of your body
through the instrument panel outlets, and warmed air is
directed through the heater ducts and defroster vents. At
times, this temperature difference may be more apparent
than others.
The air conditioner compressor operates in all air
conditioning positions, and in
DEF (defrdst) when the
outside temperature is above about
40°F (4.5"C).
r gii
The DEF setting directs most of the air through the
defroster vents and some through the heater dl
s.
To quickly defog the windshield, set the upper le ~ r to
DEF and move the fan switch to HI. Slide the lower
lever to HOT.
In damp, cool weather (temperatures about 45"to
65"F,
7 " to 18 " C), you can use BI-LEV to defog the side
windows. Set the upper lever to BI-LEV and the fan
switch to HI. Aim the side vents toward the side
windows, For increased airflow to the side vents, close
the center vents.

Rear Window Defogger
REAR
!
The rear window defogger
uses
a warming grid to
remove fog from the rear
window. In winter, it can
also keep ice from forming
on the rear window.
Press the
ON portion of the switch. The indicator light
will glow. The rear window defogger
will turn off
automatically after about 10 minutes of use. You can
also
turn it off by turning off the ignition or pressing the
OFF portion of the switch.
I NOTICE:
Don’t use a razor blade or something else sharp
on the inside
of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn’t be covered by your warranty.
Ventilation System
Your Buick’s flow-through ventilation system supplies
outside air into the vehicle when
it is moving. Outside
air
will also enter the vehicle when the heater or the air
conditioning fan is running.
For mild outside temperatures, when
little heating or
cooling is needed, slide the upper lever to VENT.
Airflow is through the instrument panel outlets. Rotate
the control next to the outlets to turn on, adjust or turn
off the airflow. Adjust the lower lever
on the control
panel
to the temperature desired.

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.
When you enter
a vehicle in cold weather, turn the
blower fan to
HI for a few moments before driving
off. This helps clear the intake ducts of snow and
moisture, and reduces the chance of fogging the
inside of your windows.
Keep the air path under the front seats clear
of
objects. This helps air to circulate throughout
your vehicle.
Audio Systems
Your Delco' audio system has been designed to operate
easily and give years
of listening pleasure. You will get
the most enjoyment out
of it if you acquaint yourself
with it first. Find out what your Delco system can do
and how to operate all its controls,
to be sure you're
getting the most out of the advanced engineering that
went into
it.

Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can’t see !it or smell it,
so you might not
know it
is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking ‘your exhaust pipe. And check
around again from time
to time to be sure snow
doesn’t collect there.
Open a window just a little on the side of the
vehicle that’s away from the wind.
This will help
keep
CO out.
Run your erigine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly.
This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery
to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for awhile.
Then, shut the engine
off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this
only when you feel really uncomfortable
from the cold. But
do it as little as possible. Preserve the
fuel as long as you can.
To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour
or so until help comes.

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 NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@)
or DRIVE (D). 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 ofthe 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.

(ACA u TT” I:
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.
2.2L L4 Engine
3.1L V6 Engine
The coolant level should be at 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.
5-16
ProCarManuals.com

A C U-ION:
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, with the engine on, 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 ADD, add a
50/50 mixture of clean water
(preferably distilled) and DEX-COOL (orange-colored,
silicate-free) antifreeze at
the coolant recovery tank. (See
“Engine Coolant” in the Index for more information.)
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.

I I
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.
. .. .
i.
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.
1
When the coolant in the coolant recovery tank is at 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 raqiator, but be sure the cooling system is:
cool before you do it.
