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)
2.2L Engine

Downloaded from www.Manualslib.com manuals search engine 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 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.
2.4L Engine
In very cold weather,
0°F (- 18 O C) or colder, the engine
coolant heater 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.
To 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.
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 Chevrolet dealer in the area where you’ll be
parking your vehicle. The dealer can give you the best
advice for that particular area.

TEMP
Low Coolant Warning Light

If this light comes on and
stays on, your system is low
on coolant and the engine
may overheat.
Your vehicle
is equipped with one of these gages. 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.
In “Problems on the Road,” this manual shows what
to
do. See “Engine Overheating” in the Index. See
the Index under “Engine Coolant” and have your
vehicle serviced
as soon as you can.

Downloaded from www.Manualslib.com manuals search engine Heating
On cold days, use FLOOR with the temperature knob all
the way in the red area. The system will bring in outside
air, heat it and send it to the floor ducts.
Your vehicle has heat ducts that are directed toward
the rear seat. Keep the area under the front seats clear
of obstructions so the heated air can reach the rear
seat passengers.
If your vehicle has an engine coolant heater, you can use
it
to help your system provide warm air faster when it’s
cold outside
(0°F (-18°C) or lower). An engine coolant
heater warms the coolant your engine and heating
system
use to provide heat. See “Engine Coolant
Heater’’ in the Index.
Ventilation System
For mild outside temperatures when little heating or
cooling
is needed, use VENT to direct outside air through
your vehicle. Your vehicle
also has the flow-through
ventilation system described later in this section.
Your vehicle’s flow-through ventilation system supplies
outside air into
the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan
is running.

Downloaded from www.Manualslib.com manuals search engine Engine Overheating
You will find a coolant temperature gage and a
low coolant warning light on your Chevrolet’s
instrument panel. 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.
I NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.

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.

it isn’t, you may have a leak in the radiator hoses, heater
hoses, radiator, water pump
or somewhere else in the
cooling system.
’ A C * UTION:
-- I
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.
I NOTICE:
r
~~ ~
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.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant Surge
Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
FULL COLD mark, add a 50/50 mixture of
clean water (preferably distilled) and DEX-COOL TM
antifreeze at the coolant surge tank, but be sure the
cooling system, including the coolant surge tank
pressure cap,
is cool before you do it. (See “Engine
Coolant”
in the Index for more information.)
I A CAUTION:
-
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the coolant
surge tank pressure cap
-- even a little -- they
can come out at high speed. Never turn the cap
’ CAUTION: (Continued) when
the cooling system, including the coolant
surge
tank pressure cap, is hot. Wait for the cooling
system and coolant surge tank pressure cap to cool
if you ever have to turn the pressure cap.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
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 NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant. You
can be burned if you spill coolant
01 lot
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.
