Climate Control System
With this system, you can control the
ventilation and heating in your vehicle.
Your vehicle
also has the flow-through
ventilation system described later in this
section.
Lever Controls: The upper lever
changes the functions of your system.
The lower lever changes the temperature
of the air coming through the system.
Slide the upper control lever to
OFF to
turn
off the system.
3f : Sets the fan speed. To select the
force of air you want,'turn the knob.

VENT Use when outside temperatures
are mild and little heating or cooling is
needed. Air flow is through the
instrument panel outlets. Set the lower
lever to the temperature desired.
B/L (Bi-Level): Use on cool, but SUMY
days. This setting brings in the outside
air, but directs it in
two ways. The cool
air is directed to the upper portion of your
body through the instrument panel outlets,
but slightly warmer air is directed through
the heater ducts and defroster vents. At
times, this temperature difference may
be more apparent than others.
HTR (Heater): This setting brings
heated air through the heater ducts, and
some through the windshield defroster
vents.
If you have the optional engine block
heater and use it during cold weather,
0°F (-18°C) or lower, your heating
system will more quickly provide heat
because the engine coolant is already
warmed. See the
Index under Engine
Block Heater.
BLEND: This setting divides the air
flow equally between the heater ducts
and the windshield defroster vents.
DEF (Defrost): This setting directs
most air through the windshield
defroster vents, and some through the
heater ducts.
Defogging Windows
Slide the lower lever to HOT. To defog
the windows, set the upper lever to
DEF
and turn the fan control to HI.

How to Add Coolant to the Coolant
Recovery Tank
(or the Coolant Surge
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
(or coolant surge tank). If you have the
coolant surge tank, be sure
the cooling
system, including the coolant surge
tank
pressure cap, is cool before you do it.
See How To Add Coolant to the 2.2L L4
Engirze at the Radiator or How to Add
Coolant
to the 3.1L V4 Engine ut the
Coolant
Surge Tank later in this section.
A
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 cool an^
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 50150 mix
of clean water and a proper
antifreeze. In cold weather, water can freezt
and crack the engine, radiator,
heater core and other parts Ise
the recommended coolant.

FULL COLD.
5. Put the cap back on the coolant
recovery tank, but leave the radiator
pressure cap off. 6. Start the engine and let it run until
you can feel the upper radiator hose
getting hot. Watch
out for the engine
fan.
7. 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.

proper
mix, up to FULL COLD.
4. With the coolant surge tank pressure
cap
off, start the engine and let it run
until you can feel the upper radiator
hose getting hot. Watch out for
the
engine fan.
By this time, the coolant level inside the
coolant surge tank may be lower. If the
level
is lower, add more of the proper
mix to the coolant surge tank until the
level reaches
FULL COLD.
5. Then replace the pressure cap. Be
sure the arrows on the pressure cap
line up like this.

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 the Index under
Engine Overheating.
The proper coolant for your Chevrolet
will:
Give freezing protection down to
Give boiling protection up to 262°F
Protect against rust and corrosion.

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.
If you have a 2.2L LA engine, your
engine coolant system will have a
coolant recovery
tank. If you have a
3.1L V6 engine, your engine coolant
system will have a coolant surge
tank.
There are important differences between
these two cooling systems. Read this section carefully.

Adding Coolant-2,21 L4 Engine
To Check Coolant:
When your engine
is cold, the coolant
level should be at
FULL COLD, or a
little higher. When your engine
is warm,
the level should be up to
mJLL HOT,
or a little higher.
To Add Coolant:
If you need more coolant, add the
proper
mix at the coolant recovery
tank.
