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.

With this system, you can control the

Your vehicle
also has the flow-through
ventilation system described later in this

The lower lever changes the temperature
of the air coming through the system.

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.

Engine Overheating
You will find a coolant temperature gage
on your Chevrclet's instrument panel.
If your engine catches fire because
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.

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

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.

Thermostat
Engine coolant temperature is controlled
by a thermostat in the engine coolant
system. The thermostat stops the
flow of
coolant through the radiator until the
coolant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
Power Steering Fluid
How to Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and
look at the fluid level on
the dipstick.
When the engine compartment is hot,
the level should be near the H mark.
When the engine compartment is cool,
the level should be near the

Accessory Drive Belt(s) Inspection*-
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
Cooling System Service*-Drain, flush and refill
the system with
new or approved recycled coolant
conforming to
GM Specification 1825M. Keep
coolant at the proper mixture as specified. See the
Index under Coolant. This provides proper freeze
protection, corrosion inhibitor level and engine
operating temperature.
Inspect hoses and replace if they are cracked,
swollen or deteriorated. Tighten screw-type hose
clamps. Clean the outside of the radiator and air
conditioning condenser. Wash
the pressure cap and
neck.
To help ensure proper operation, we recommend a
pressure test of both the cooling system and the
pressure cap.
