Engine Coolant Temperature Warning Light
This light tells you that your engine
coolant has overheated or your radiator
cooling fan is not working. If you have
been operating your vehicle under normal driving conditions, you should
pull
off the road, stop your vehicle and
turn the engine
off as soon as possible.
HOT COOLANT CAN BURN YOU
BADLY!
In
Problems on the Road, this manual
shows what to
do. See the Index under
Engine Overheating.
Engine Coolant Temperature
Gage
(OPTION)
If you have the gage cluster, you have a
gage that shows the engine coolant
temperature. If the gage pointer moves
into the red area, your engine is too hot!
That reading means the same thing as
the warning light. 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.

Low Coolant Warning Light
(v6 ENGINES)
If this light comes on, your system is
low on coolant and the engine may
overheat. See the
Index under Engine
Coolant and have your vehicle serviced
as soon as you can.

Downloaded from www.Manualslib.com manuals search engine Torque Lock
If you are parking on a hill and you
don’t shift your transaxle into
P (Park)
properly, the weight of the vehicle may
put too much force on the parking pawl
in the transaxle. You may find it
difficult
to pull the shift lever out of
P (Park). This is called “torque lock.”
To prevent torque lock, always be sure
to shift into
P (Park) properly before
you leave the driver’s seat. To find out
how, see the
Index under Shifting Into
P (Park).
When you are ready to drive, move the
shift lever out of
P (Park) before you
release the parking brake.
If torque lock does occur, you may need
to have another vehicle push yours a
little uphill to take some
of the pressure
from the transaxle, so you can pull the
shift lever out of
P (Park).
Winter Driving
Here are some tips for winter driving:
Have your Chevrolet in good shape
for winter. Be sure your engine
coolant mix
is correct.
Snow tires can help in loose snow,
but they may give you less traction on
ice than regular tires.
If you do not
expect to be driving in deep snow, but
may have to travel over ice, you may
not want to switch to snow tires at all.
You may want to put winter
emergency supplies in your trunk.
Include an ice scraper, a small brush
or broom, a supply of windshield
washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight,
a
red cloth, and a couple of reflective
warning triangles. And, if you will
be
driving under severe conditions,
include a small bag of sand, a piece
of
old carpet or a couple of burlap bags
to help provide traction. Be sure you
properly secure these items in your
vehicle.

If you get the overheat warning but see

can get

Stop after high speed driving.

Engine Overheating
You will find a coolant temperature
gage or the warning light about a hot
engine on your Chewolet’s instrument
panel. You also have a low coolant
warning light on your instrument panel.
See the
Index under Coolant
Temperature Gage for the gage cluster. Steam from
an overheated
engine can burn you badly,
/I‘ 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.
2. Tm on your heater to full hot at the

window as necessary.

If you no longer have the overheat
warning, you can drive. Just to be safe,
drive slower for about ten 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,

You may decide not to lift the hood but

The coolant level should be at or above
the
COLD mark.
If it isn’t, you may have a leak in the
radiator hoses, heater hoses, radiator,
water pump or somewhere else in the
cooling system.
Heater and radiator hoses,
L L 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.
1 NOTlCE CAUTION
If you haven’t found a problem yet, but
the coolant level isn’t at or above
COLD, add a 50/50 mixture of clean
water
(preferably distilled) and a proper
antifreeze at the coolant recovery tank.
(See the
Index under Engine Coolant
for more information about the proper
coolant mix.)

A Adding only plain water to
your cooling system can be
Amgerous. Plain water, or some

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

Ifa Tire Goes Flat
It’s unusual for a tire to “blow OU~,)
while you’re driving, especially if you
maintain your tires properly. If air goes
out of a tire, it’s much more likely to
leak out slowly. But
if you should ever
have a “blowout,” here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will
create a drag that pulls the vehicle
toward that side. Take your foot
off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop
well out of the traffic lane.
A rear blowout, particularly on a curve,
acts much like a
skid and may require
the same correction you’d use in a
skid.
In any rear blowout, remove your foot
from the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It may
be very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If your tire goes flat, the next section
shows how
to use your jacking
equipment to change a
flat tire safely.
