engine overheat CHEVROLET AVEO 2002 Service Owner's Manual

Adding Coolant
If the level falls below the Minimum (B) mark, add the
proper 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. SeeCooling System
on page 5-26for instructions on “How to Add Coolant
to the Coolant Surge Tank.”
{CAUTION:
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. Do not spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight and fully seated.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel cluster. SeeEngine Coolant
Temperature Gage on page 3-28.
If Steam Is Coming From Your Engine
{CAUTION:
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 you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re. You
or others could be badly burned. Stop your
engine if it overheats, and get out of the
vehicle until the engine is cool.
5-24

Notice:If your engine catches re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not be
covered by your warranty.
If No Steam Is Coming From Your
Engine
If you get an engine 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.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
2. Turn on your heater to full hot at the highest fan
speed and open the windows as necessary.If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning does not come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over, stop, and park your vehicle right away.
If there is still no sign of steam, you can idle the engine
for three minutes while you are parked. If you still
have the warning, turn off the engine and get everyone
out of the vehicle until it cools down.
You may decide not to lift the hood, but to get service
help right away.
5-25

{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them. If
you do, you can be burned.
Do not run the engine if there is a leak. If you
run the engine, it could lose all coolant. That
could cause an engine re, and you could be
burned. Get any leak xed before you drive the
vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fan is running. If
the engine is overheating, the fan should be running. If
it is not, your vehicle needs service.
Notice:Engine damage from running your engine
without coolant is not covered by your warranty.
How to Add Coolant to the Coolant
Surge Tank
Notice:This vehicle has a specic coolant ll
procedure. Failure to follow this procedure could
cause your engine to overheat and be severely
damaged.
If you have not found a problem yet, check to see if
coolant is visible in the surge tank. If coolant is visible
but the coolant level is not between the Minimum
and Maximum marks, add a 50/50 mixture of clean,
drinkable water and proper coolant at the coolant surge
tank, but be sure the cooling system, including the
coolant surge tank pressure cap, is cool before you do
it. SeeEngine Coolant on page 5-22for more
information.
5-27

If no coolant is visible in the surge tank, add coolant as
follows:
{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 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.
{CAUTION:
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 would not get the overheat warning.
Your engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and a proper coolant.
Notice:In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.

Headlamp Wiring
The headlamp wiring is protected by fuses, one for each
headlamp, in the fuse block. An electrical overload
will cause the lamps to turn off. If this happens, have
your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.
Power Windows and Other Power
Options
Circuit breakers in the fuse block protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is fixed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links in the wiring itself.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
There are spare fuses provided in the engine
compartment fuse block. If you ever have a problem on
the road and do not have a spare fuse, you can borrow
one that has the same amperage. Just pick a feature of
your vehicle that you can get along without — like the
radio or cigarette lighter — and use its fuse, if it is the
correct amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: the instrument
panel fuse block and the engine compartment fuse
block.
There is a fuse puller located on the engine
compartment fuse block. It can be used to easily
remove fuses from the fuse block.

an instrument cluster gage connected to the VSS on the transaxle output shaft. The trip odometer can be reset to
zero at any time so that the driver can record the distance traveled from any starting point.
Fuel Gage
The fuel gage consists of an instrument cluster gage connected to a sending unit in the fuel tank.
The fuel gage indicates the quantity of fuel in the tank only when the ignition switch is turned to ON or ACC.
When the ignition is turned to LOCK or START, the pointer may come to rest at any position.
Temperature Gage
The temperature gage consists of an instrument cluster gage connected to a temperature sensor that is in contact
with the circulating engine coolant.
The temperature gage indicates the temperature of the coolant. Prolonged driving or idling in very hot weather
may cause the pointer to move beyond the center of the gage. The engine is overheating if the pointer moves
into the red zone at the upper limit of the gage.
Instrument Cluster Indicator Lamps
The instrument cluster contains indicator lamps that indicate the function of certain systems or the existence of
potential problems with the operation of the vehicle. The indicator lamps are replaceable. For replacement of
the indicator lamps contained in the instrument cluster, refer to Bulb Usage Specifications
and Instrument
Cluster Lamp Replacement .
Chime Module
The chime module is located above the instrument panel fuse block and will sound in order to bring attention to
one or more of the following conditions:
The lamps are ON, the door is ajar, and the ignition switch is not in ACC, ON, or START.
The seat belt is unbuckled when the ignition switch is in ON or START.
The door is open when the ignition switch is in ON or START.
The key is left in the ignition switch when the ignition is in LOCK and the door is open.
