Engine Coolant Heater
3400 V6 Engine
2.2L L4 ECOTEC Engine In very cold weather, 0°F (-18°C) or colder, the engine
coolant heater,
if your vehicle has this feature, 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. At temperatures above
32°F (OOC),
use of the coolant heater is not required.
2-22

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. On
the 2.2L L4 ECOTECTM engine, the engine coolant
heater cord is located in front of the coolant
surge tank on the passenger’s side of the engine
compartment. On the 3400
V6 engine, the
engine coolant heater cord is located near the
engine air cleaner/filter. See
Engine Compartment
Overview
on page 5-12 for more information on
location.
3. Plug it into a normal, grounded 1 IO-volt AC outlet.
4. Before starting the engine, be sure to unplug and
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 dealer in the area where you’ll be parking your
vehicle. The dealer can give
you the best advice for that
particular area.
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 seriouslv
injured. Plug the cord into a properly grounded
three-prong
1 IO-volt AC outlet. If the cord
won’t reach, use a heavy-duty three-prong
extension cord rated for at least
15 amps.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Operation
To change the current mode, select one of the following:
f;’ (MAX): This mode is used for maximum cooling.
It will recirculate much of the air inside your vehicle.
It maximizes your air conditioner’s performance and your
vehicle’s fuel economy. The air-conditioning compressor
will run automatically in this mode when it is needed
to help dry the air in the vehicle.
2 (Vent): This mode directs air to the instrument
panel outlets.
tf;’ (Bi-Level): This mode directs half of the air to the
instrument panel outlets, then directs most of the
remaining air
to the floor outlets with some air directed
at the side windows.
@ (Floor): This mode directs most of the air to the
floor outlets with some air directed to the side windows.
The right knob can
also be used to select defog or
defrost modes. Information on defogging
and defrosting
can be found later in this section.
@ (Fan): Turn the left knob clockwise or
counterclockwise
to increase or decrease the fan speed.
Temperature Control: Turn the center knob clockwise
or counterclockwise to manually increase or decrease
the temperature inside your vehicle.
When it’s cold outside
0°F (-18°C) or lower, use the
engine coolant heater,
if equipped, to provide warmer air
faster to your vehicle. An engine coolant heater warms
the coolant that the engine uses
to provide heat to
warm the inside of your vehicle. For more information,
see Engine
Coolant Heater on page 2-22.

Engine Coolant Temperature Gage
L
United States Canada
This gage shows the engine coolant temperature.
If the
gage pointer moves into the red area, the light comes
on and you hear a chime, your engine is
too hot! It
means that your engine coolant has overheated. See
Engine Overheating on page 5-26.
Low Coolant Warning Light
This light comes on briefly
when you turn your
ignition on.
COOLANT
If this light comes on and stays on and you hear a
chime, the coolant level in your vehicle is
low.
See Engine Coolant on page 5-23. If the light is on
along with an overheat warning, you may have a serious
overheating problem. See
Engine Coolant Temperature
Gage on page
3-30.
Notice: Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
See
Engine Overheating on page 5-26 for information
on what
to do.
Your vehicle should be serviced as soon as possible.
3-30

A 50/50 mixture of clean, drinkable water and
DEX-COOL@ coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice: When adding coolant, it is important that
you use only DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL
is added to
the system, premature engine, heater core or radiator corrosion may result.
In addition, the engine
coolant will require change sooner
-- at 30,000 miles
(50,000 km) or 24 months, whichever occurs first.
Damage caused by the use of coolant other
than DEX-COOL@ is not covered by your new vehicle
warranty.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL@ coolant which won’t damage
aluminum
parts. If you use this coolant mixture,
you don’t need to add anything else.
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, 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 mixture of clean,
drinkable water and the proper coolant.
Notice: If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty.
Too much water in the mixture can freeze
and crack the engine, radiator, heater core and
other parts.

L
LOW
COOLANT
If the LOW COOLANT light r-
-
comes on and stays on, it
means you’re low on
engine coolant.
See
Low Coolant Warning Light on page 3-30.
Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture
at the surge tank, but only when the
engine is cool.
If the surge tank is empty, a special fill
procedure is necessary. See Engine Overheating
on page
5-26 and “How to Add Coolant to the Coolant
Surge Tank under
Cooling System on page 5-29
for instructions. 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.

When replacing the pressure cap, make sure it is
hand-tight.
Engine Overheating
You will find a coolant temperature gage and a low
coolant warning light on your vehicle’s instrument panel.
