cooling CHEVROLET CAVALIER 1995 3.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine setting is used for long periods of time, the air in your
vehicle may become too dry.
For normal cooling
on hot days, use VENT with the
temperature knob in the blue area and the
NC button
pushed in. The system will bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI-LEVEL with the temperature knob in
the middle and the A/C button pushed
in. The system
will bring in outside air and direct slightly warmer air to
your lower body. You may notice this temperature
difference more at some times
than others.
Heating
On cold days use FLOOR with the temperature 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
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.
Defogging and Defrosting Windows
Your system has two settings for clearing the front and
side windows. To defrost
the windows quickly, use
DEFROST with the temperature knob all
the way in the
red area. To warm passengers while keeping the
windows clean, use
DEFOG.
To defog the side windows while using the air
conditioner, set the right control to BI-LEVEL, the fan
control
to the highest setting, and press the A/C button.
Aim
the side vents toward the side windows. For
increased air flow
to the side vents, close the center
vents.

Downloaded from www.Manualslib.com manuals search engine If you drive regularly in steep country, or if you’re
planning
to visit there, here are some tips that can make
your trips safer and more enjoyable.
0 Keep your vehicle in good shape. Check all fluid
levels and
also the brakes, tires, cooling system and
transaxle. These parts can work hard
on mountain
roads.
0 Know how to go down hills. The most important
thing to know is this:
let your engine do some of the
slowing down. Shift to a lower gear when you go
down
a steep or long hill. 0

0
Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the
hill better.
Stay
in your own lane when driving on two-lane
roads
in hills or mountains. Don’t swing wide or cut
across the center
of the road. Drive at speeds that let
you stay
in your own lane.
As you go over the top of a hill, be alert. There could
be something
in your lane, like a stalled car or an
accident.
You may see highway signs
on mountains that warn of
special problems. Examples are long grades, passing or
no-passing zones,
a falling rocks area, or winding
roads.
Be alert to these and take appropriate action.

Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
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, 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.
Towing A Trailer
Do not tow a trailer with a Cavalier 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.
Your Cavalier is neither designed nor intended to tow a
trailer.

When
you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant surge tank with pressure cap.
B. Electric engine fan.

Downloaded from www.Manualslib.com manuals search engine If the coolant inside the coolant surge tank is boiling,
don't do anything else
until it cools down.
I
The coolant level should be at the FULL 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.
I NOTICE:
I
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 fm 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
c-lean water (preferably distilled) and a proper 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 about
the proper coolant mix.)

Downloaded from www.Manualslib.com manuals search engine NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
I. You can remove the coolant surge tank pressure cap
when the cooling system, including
the coolant surge
tank pressure cap and upper radiator hose,
is no

Downloaded from www.Manualslib.com manuals search engine When to Check and What to Use
Refer to the Maintenance
Schedule to determine
how often you should
check the fluid level in
your clutch master
cylinder reservoir and
for the proper fluid. See
“Owner Checks and
Services” and
“Recommended Fluids
and Lubricants” in the
Index.
How to Check
You do not need to check the fluid level unless you
suspect a clutch problem. To check the fluid level, take
the cap
off. If the fluid reaches the step inside the
reservoir, the fluid level
is correct.
Engine Coolant
The following explains your cooling system and how to
add coolant when it is low.
If you have a problem with
engine overheating, see “Engine Overheating” in the
Index.
The proper
coolant for your Chevrolet will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262°F (128°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.

Downloaded from www.Manualslib.com manuals search engine Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
i or corroded. If wheel nuts keep coming loose, the wheel,
' wheel bolts, and wheel nuts should be replaced. If the
wheel leaks air, replace
it (except some aluminum
I wheels, which can sometimes be repaired). See your
Chevrolet dealer if any
of these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have the same load carrying
~ capacity, diameter, width, offset, and be mounted the
same way as the
one it replaces.
~ If you need to replace any of your wheels, wheel bolts,
' or wheel nuts, replace them only with new GM original
i equipment parts. This way, you will be sure to have the
~ right wheel, wheel bolts, and wheel nuts for your
Chevrolet model. NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling,
speedometer/odometer calibration, headlamp
aim, bumper height, vehicle ground clearance,
and tire or tire chain clearance to the body and
chassis.
