Downloaded from www.Manualslib.com manuals search engine TEMP-PRESS AND GEN-FAN INDICATORS
These indicators provide a check on the operating
condition of the engine and the generator. Both indi­
cators should light with the ignition switch ON before
starting the engine and should go out after the engine
is started. The lights should remain out while engine is
operating, except the GEN-FAN indicator may flicker
when
engine is idling.
CAUTION: If either of these indicators light
while car is
being driven, immediately follow the
procedure outlined under "EMERGENCY OPER­
ATING INSTRUCTIONS," so car may be driven
to
the nearest service facility.
EMERGENCY OPERATING INSTRUCTIONS
(To be followed if either
TEMP-PRESS or GEN-FAN indi­
cators light while car is being
driven.)
1.
Set heater FAN and HEAT
controls to full "ON" positions.
(If
equipped with air conditioning, turn air condi­
tioning COOL switch to OFF.)
9
NOTE: After setting the heater controls, leave
them in that position until cause of trouble is
corrected ..
2. Stop the car as soon as driving conditions permit.
Turn ignition key to
OFF to stop engine but turn
key
back to ON so heater blower will continue
to cool engine.
3. Check for broken fan belt or belt off pulleys or
engine low oil level. If only GEN-FAN indicator
is lighted, belt is not broken or off pulleys and en­
gine oil level is satisfactory, car can be driven at
slow speeds; however, generator must be checked
and serviced as soon as possible.
4. If trouble is found to be a broken fan belt or belt
off pulleys, wait approximately five minutes, start
engine and drive car at no more than 25 miles per
hour until TEMP-PRESS indicator comes on, then
repeat Step 2.
NOTE: The GEN-FAN indicator will stay on until
fan
belt is installed .
5. Repeat Step 4 as necessary until facility is reached
where fan belt can be installed.

Downloaded from www.Manualslib.com manuals search engine DIRECT AIR HEATER The Direct Air Heater
uses engine cooling air to
heat the interior of the car.
Operation of the controls is
given below.
FAN-Controls blower speed.
Blower must not be op­
erated unless HEAT lever
is depressed.
HEAT
-Controls the amount of hot air to the system.
NOTE: When shutting off the above control lever, pull fully up until the lever snaps into the latch position.
DEF-Diverts heated air to the defroster outlets.
OPERATION FOR MAXIMUM COMFORT
• MINIMUM HEAT REQUIREMENTS-During spring and
fall in areas where climatic conditions are less severe,
depress the HEAT
lever only as required for your
comfort.
• MAXIMUM HEAT REQUIREMENTS-Depress HEAT lever
to extreme down position. If heat becomes exces­
sive, pull up HEAT
knob to desired position.
Additional rear seat
compartment heat may be
obtained by opening the
heater outlet located in the
seat riser.
Heater Operating Tips
The Direct Air Heater receives air from the air inlet
louvers below the rear window. Clean snow from this
opening and surrounding areas before operating the
heater.
Operate the heater for several minutes before turn­
ing on the defroster. This will clear the system of moisture
and help prevent windshield fogging.
Keep all windows and vents closed to reduce drafts, and noise.
Quicker defrosting may be obtained when the rear
seat heater outlets are closed.
NOTE: In Direct Air Heaters vapor may collect when vehicle stands for long periods, keep the HEAT lever in OFF position for the first few minutes of engine operation. This will reduce the tendency for moisture to condense on windshield. Oil spilled on engine shrouding may cause odor in passenger compartment. To avoid discomfort, the cause of any odor should be traced and defect prom ptly corrected.

The Corvair Corsa models are operated and main­
tained as outlined for the regular Corvair. Additional
instrumentation and operating instructions peculiar to
Corsa models only are reviewed in the following pages.
A high-performance (140 hp Turbo-Air 164) engine
is provided as the standard engine for Corsa models. The
optionally available turbocharged engine is designed
around the Turbo-Supercharger and all the related parts
22
are necessary for proper performance. Under no con­
ditions should the Turbo-Supercharger be removed and
installed on another car not equipped with the proper
engine.
Break-In Period-We recommend that the supercharger
not be used for the first 500 miles. Keep engine speed
below 2500 rpm to maintain negative readings on the
Manifold Pressure Gauge. From 500 to 1000 miles, short
bursts
are permitted but not sustained runs.
After the first 1000 miles, the car may be
driven to take full advantage of the power
from the supercharger.
Fuel and Engine Oil Requirements~Refer
to "Maintenance and Lubrication."
Air Recirculating Plate -This plate, the
same as used on
Air Conditioned Corvairs,
should be installed and removed as recom­
mended on Page 15.
Detonation -Caused by low grade fuel,
faulty timing, carbon deposits or an over­
filled crankcase, this condition is more serious
than on other engines. If detonation occurs
have your car checked by your Chevrolet
Dealer.

EXTERIOR APPEARANCE
Your Corvair is finished with General Motors "Magic­
Mirror" acrylic lacquer. This is a finish of maximum beauty
which, in depth of color, gloss retention and durability is
superior to conventional lacquer finishes.
Washing Your Corvair
The best way to preserve the finish is to keep it clean.
Normally only frequent washings are required to maintain
its original beauty. Wash the car in either warm or cold
(never hot) water, not in the direct rays of the sun, and not
while the sheet metal surfaces are hot. Never wipe dirt
from dry painted surfaces because this may scratch the
finish. The use
of strong soaps and chemical detergents
should be avoided and in any event cleaning agents
should be promptly flushed from the surface and not
allowed to dry or they may streak the finish.
Polishing and Waxing Your Corvair
Even though the acrylic paint on your car is more
durable than conventional finishes; under certain condi­
tions you may wish to wax or polish your car to provide
maximum protection. Calcium chloride and other salts,
road oil and tar, tree sap, chemicals from factory chim­
neys
and other foreign matter may damage any known
automobile finish if allowed to remain in contact with the
30
paint film. Prompt washing may not thoroughly remove
these deposits .
and, particularly in geographical areas
where these exposure conditions are severe, properly
applied polishes and waxes of known quality will pro­
vide the best protection. Chevrolet Dealers offer G. M.
Acry-Mel Hand Applied Cleaner and Polish and G. M.
Triple Action Cleaner and Polish; both are excellent for
use on acrylic finishes. Road oil and tar removers must
be warranted safe for use on acrylic finishes. Chevrolet
recommends G. M. Road Oil and Tar Remover.
Protection of. Exterior Bright Metal Parts
All bright metal parts of the car should be regularly
cleaned and protected against the same substances
harmful to the painted surfaces. NormallY, washing with
water is all that is required. Never use chrome polish,
steam or any caustic soap to clean ALUMINUM. Wash
only with luke-warm water, and if necessary, a mild soap.
Rinse well and dry thoroughly. Severe cases may be
cleaned with a cleaning compound specified for acrylic
finishes.
It is recommended that all bright metal parts of your
Corvair, after being thoroughly cleaned, be given a
coating of wax and rubbed to a high polish. This will
serve to keep corrosive agents away from these surfaces,
and should be repeated as often as required.

Use soap, warm water or a tire cleaner and a stiff
brush
to remove road grime and dirt from white sidewall
tires. A flne grade of steel wool will remove severe curb
scrapes.
Do not use gasoline, kerosene or any oil product
which would discolor or deteriorate the rubber.
CAUTION: Some white sidewall cleaners will cause
serious
damage to aluminum trim. Use caution
when cleaning tires with this
type of cleaner.

INTERIOR APPEARANCE
Dust and Dirt
Clean the interior of your car frequently, using a
broom or vacuum cleaner. A damp cloth will wipe dust
from hard surfaces.
Spots and Stains
Remove upholstery stains as soon as possible or
they may become "set" and difficult or impossible to
remove . First determine the type and age of the stain
and the kind of upholstery material. Kar Kleen Uphol­
stery Cleaner, available from your Authorized Chevrolet
Dealer, will remove most stains. Do not use alkaline
cleaners for they may damage the color or flnish of the
materials. Other solutions such as hot or cold water,
ammonia water, soap, ink eradicator, etc., will probably
discolor and disturb the material.

GASOLINE AND ENGINE OIL
In the selection of gasoline and engine oil to be
used, it is best to consider the reputation of the refiner
or marketer. This is the best means of obtaining gasoline
and oil of high quality.
Gasoline
The Corvair Turbo-Air 95 horsepower engine is
designed to operate efficiently on regular grade gas­
olines commonly sold in the United States and Canada.
The
higher horsepower performance engines are
designed to operate efficiently on premium grade gas­
olines commonly sold in the United States and Canada.
Use of regular grade gasolines in these higher per­
formance engines may result ,in excessive knocking.
Since the octane quality of all regular grade or of
all premium grade gasolines is not the same and factors
such as altitude, terrain and air temperqture affect oper­
ating efficiency, excessive' knocking may result, even
though you are using the grade of gasoline recom­
mended for your engine. If excessive knocking occurs in
your engine, it may be necessary to use the next higher
grade of gasoline, and if knocking continues, consult
your Authorized Chevrolet Dealer.
If you plan to operate your Corvair outside the
continental limits of the United States or Canada, there
is a possibility that the best fuels available are so low
32
in octane quality that excessive knocking and serious
engine trouble may result from their use. To minimize this
possibility, write to Chevrolet Motor Division, General
Motors Corporation, Service Operations Department,
Detroit, Michigan 48202 giving: Your engine serial num­
ber (see page 44), the compression ratio of your engine
(see page 44) and the country or countries in which you
plan to travel. You will be furnished details of adjust­
ments or modifications which should be made to your
engine by your Chevrolet dealer prior to your departure.
After arriving in a foreign country, contact the nearest
authorized General Motors dealer for brand names of
the best fuels available and advice as to where they
may be purchased.
In all cases excessive knocking should be avoided
as much as possible in order to prevent possible engine
damage. Operation of your car under conditions of con­
tinuous or excessive knocking constitutes misuse of the
engine for which the Chevrolet Division is not responsible
under the terms of the manufacturer's New Vehicle
Warranty.
ENGINE LUBRICATION
The use of a high quality oil of the correct viscosity
is your best assurance of continued reliability and per­
formancefrom your engine. It is recommended that
/ /

Downloaded from www.Manualslib.com manuals search engine you use an oil which, according to the label on the can
is (1) intended for service MS and (2) passes car makers'
tests or meets General Motors Standard GM 4745-M .
Oils conforming to these types contain detergent addi­
tives. Your serviceman will be pleased to assist you in
selecting the proper oil for your car.
Check the oil level (with the engine hot) on the dip­
stick frequently. Keep oil level between the FULL and
ADD marks, by adding oil when level is at or below
ADD mark. Do not overfill. Poor performance and pos­
sible engine damage may result if the crankcase is
overfilled. Drain and refill the crankcase very 60 days
or 6000 miles, whichever occurs first.
For vehicles
in heavy duty operation involving con­
tinuous stop-
start or prolonged idling, engine oil should
be changed after 2500-3000 miles of operation.
NOTE: When checking or adding oil, be care­
ful to avoid spilling or dropping oil onto the
engine shrouding.

COOLING SYSTEM CARE
The engine fan belt should be checked for tightness
at regular intervals. When a new belt is needed use only
the approved premium belt available from your Chev­
rolet dealer. If any other belt is installed, replace with
recommended belt when possible .
Watch the TEMP-PRESS and GEN-FAN indicators on
the instrument panel for signs of overheating.
Air inlet louvers, located in the panel below the rear
window on Corvair models, or in the Corvair Greenbrier
upper rear quarter panels, supply air for engine combus­
tion
and cooling and for the Direct Air Heater. Make
sure the louvers are never sealed or blocked.
BATTERY CARE
Check fluid level frequently. Keep filled with distilled
water to level of split ring in vent tube.

The time or mileage intervals on the following pages
are intended as a general guide for establishing regular
maintenance and lubrication periods for your Corvair.
Sustained heavy duty or high speed operations or oper­
ation under adverse conditions may necessitate more
frequent servicing. For specific recommendations for con­
ditions under which you use your vehicle, consult your
authorized Chevrolet Dealer.
