1998 CHEVROLET CAVALIER engine overheat

Downloaded from www.Manualslib.com manuals search engine Low Coolant Warning Light
If this light comes on and
stays on, your system is low
on coolant and the engine
may overheat.
See “Engine Coolant” in the Index and have your
vehicle serviced as soon as you can.
Malfunction Indicator Lamp
(Check Engine Light)
CHECK
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems. This system is called
OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to assure that emissions are at acceptable levels for
the life
of the vehicle, helping to produce a cleaner
environment. The
CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run
as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.

When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Chevrolet dealer. The green arrows on your
instrument panel will flash whenever
you signal a turn
or lane change. Properly hooked up, the trailer lamps
will also flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash
for turns even if the bulbs on
the trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they
are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
NOTICE:
Do not tow on steep continuous grades exceeding
6 miles (9.6 km). Extended, higher than normal
engine and transaxle temperatures may result
and damage your vehicle. Frequent stops are
very important
to allow the engine and transaxle
to cool.
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning (if you
have this option) to reduce engine load (see “Engine
Overheating” in the Index).

Downloaded from www.Manualslib.com manuals search engine Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that
are especially important in trailer
operation are automatic transaxle fluid (don’t overfill), engine oil, drive belt, cooling system and brake
adjustment. Each of these
is covered in this manual, and
the Index will help you find them quickly. If you’re
trailering, it’s a good idea to review these sections before you start your trip.
Check periodically
to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.
Towing a Trailer (Except Models
with
2.4L Engine and 4-Speed
Automatic Transaxle)
Do not tow a trailer if your vehicle is:
a convertible model.
equipped with a 2.2L (Code 4) engine.
equipped with a manual transaxle or a three-speed
automatic transaxle.

You will find a coolant temperature gage and a low
coolant warning light on your vehicle’s instrument
panel. See “Engine Coolant Temperature Gage” and
“Low Coolant Warning Light’’ in the Index.
If Steam Is Coming From Your Engine
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 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.
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.

Downloaded from www.Manualslib.com manuals search engine If No Steam 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.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise,
shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (D) for
four-speed automatic or DRIVE
(D) for three-speed
automatic transaxles. If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 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 oflthe 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.

Downloaded from www.Manualslib.com manuals search engine 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
isn’t, your vehicle needs service.
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@
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. (See “Engine Coolant” in the
Index for more information.)
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.

Adding only plain wirccr to your cooling system
can be dangerous. Plain water, or some other
liquid like 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 water and
DEX-COOL@ coolant.
