Engine Coolant Temperature
Gage
With the ignition in the Run position,
this gage shows
the engine coolant
temperature.
If the gage pointer moves into the red
area, your engine is
too hot! 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.

Law Coolant Warning Light
(3.7L V6 ENGiNE)
If this light comes on and stays on, your
system is low on coolant and the engine
may overheat. See the
Index under
Coolant and have your vehicle serviced
as soon as
you can.

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.

Downloaded from www.Manualslib.com manuals search engine Torque Lock
(AUTOMATIC TRANSAXLE)
If you are parking on a hill and you
don’t shift
your transaxle into P (Park)
properly, the weight of the vehicle may
put too much force on the parking pawl
in the transaxle. You may find it difficult
to pull the
shift lever out of P (Park).
This
is called “torque lock.” To prevent
torque lock, always be sure to shift into
P (Park) properly before you leave the
driver’s seat.
To find out how, see the
Index under Shiftirtg Into P (Park),
When you are ready to drive, move the
shift lever out
of P (Park) before you
release the parking brake.
If torque lock does occur, you may need
to have another vehicle push yours a
little uphill to take some
of the pressure
from the transaxle,
so you can pull the
shift lever out
of P (Park).
Winter Driving
Here are some tips for winter driving:
Have your Chevrolet in good shape for
winter. Be sure your engine coolant
mix is correct.
Snow tires can help in loose snow, but
they may give you less traction on ice
than regular tires.
If you do not expect
to be driving in deep snow, but may
have to travel over ice,
you may not
want to switch to snow tires at all.
You may want to put winter
emergency supplies in your trunk or
rear area.
Include an ice scraper, a small brush
or broom, a supply of windshield
washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight,
a
red cloth, and a couple of reflective
warning triangles. And, if you will be
driving under severe conditions,
include a small bag
of sand, a piece of
old carpet or a couple
of burlap bags
to help provide traction. Be sure you
properly secure these items
in your
vehicle.

Engine Overheating

on your Chevrclet's instrument panel.

you keep driving with
no coolant,
your vehicle can be badly

If Steam is Corning from Your Engine
A
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.
If No Stem 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.

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

You may decide not to
lift the hood but
to get service help right away.
If you have
a 2.2L L4 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.

Engine Overheating (CONT.)
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 pump
or
somewhere else in the cooling system.
II Heater and radiator hoses, and
L 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.
Engine damage from running
your
engine without coolant isn't
