1965 CHEVROLET CORVAIR fuel

Downloaded from www.Manualslib.com manuals search engine OPERATING INSTRUCTIONS
Sound design and precIsion manufacturing methods
will permit you to operate your new Corvair without
adhering to a formal "break-in" schedule. However,
during the first few hundred miles of driving you can,
by observing a few simple precautions, add to the future
performance and economy of your car.
It is recommended that your speed during the first
500 miles be confined to a maximum of 60 MPH, but
do not drive for extended periods at anyone constant
speed, either fast or slow. During this period, avoid full
Proper maintenance and wise operation will com­
bine to help you achieve maximum fuel economy with
your Corvair. Your Authorized Chevrolet Dealer can
properly tune and maintain your car but wise operation
is your responsibility. Give the car sufficient warm-up
throttle starts and unnecessary, quick abrupt stops.
Gentle braking during the first few hundred miles of
operation will result in longer brake life and better
future performance. Avoid unnecessary, hard stops espe­
cially during the first 200 miles of operation since brake
misuse during this period will destroy much future brake
efficiency.
Always drive at a moderate speed until the engine
has completely warmed up.
time, do not make "Full Throttle" starts or unnecessary
skidding stops, and drive at reasonable speeds and as
steady as traffic permits to gain the benefits of all the
economy built into your Corvair.
CAUTION: Carbon monoxide is a poisonous gas produced by the engine of any car. It is odor­
less,
so you cannot detect its presence. Be safe. Never start or run engine in a closed garage,
and do not sit in a parked car with engine running unless windows are open.

All driving instruments are grouped in the instrument
cluster
which is located immediately in front of the driver
to provide quick reading and maximum convenience and
accessibility. The TEMP-PRESS and GEN-FAN indicators
provide important information concerning the condition
of the engine and should be observed regularly during
operation of the car. The information on these pages
will help you understand the operation of these instru­
ments. The illustrations here
and on page 10 will ac­
quaint you with the instrument cluster and the instrument
panel as a whole.
FUEL GAUGE
This electrically operated
gauge accurately indicates
the amount of fuel in the fuel
tank only when the ignition
switch is in the ON position.
When the ignition is "off",
the indicator pointer will not
necessarily return to the
empty IE) mark, but may stop
8
at any point on the gauge. Therefore, always be sure
that the ignition switch is "on" when reading the fuel
gauge.
SPEEDOMETER
Conveniently located in the instrument cluster di­
rectly ahead of the driver, the speedometer shows at a
glance the speed of the car in miles per hour. The
odometer, encircled within the speedometer dial, reg­
isters accumulated vehicle mileage.

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.

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

The chart on the previous page, and the information on the pages
which follow, contains information designed to aid the average
driver to discover, and possibly correct, conditions resulting in minor
mechanical difficulties
in his cor. The chart, designed to point out
possible solutions to severol of the most common automotive mal­
functions and point out a logical checking sequence, will lead step
by step to the most
likely causes and corrective procedures. If, after
making the checks and adjustments suggested, the source of the
trouble has not been found and corrected, it is strongly recom.
mended that on Authorized Chevrolet Dealer inspect the vehicle and
make whatever repairs or adjustments are necessary.
FUEL SYSTEM AND ENGINE
If the ignition switch will couse the engine to "turn over" or
"cronk" but the cor will not start, check Steps A through D below.
NOTE: If continual "flooding" of the carburetor is evidenced by a
carburetor wet with fuel or black exhaust smoke, perform the
operation suggested in paragraph D only.
(A) The first and most obvious,
and one of the most frequently overlooked, items to check when
you
have difficulty in starting your
cor is the amount of fuel in the
tonk.
Make it a habit to check the
FUEL GAUGE regularly and most especially at a time when the en­
gine will "turn over" but will not
start.
(8) If the fuel tank is not empty, Checking Fuel Flow
48
you may check further to see whether the fuel is reaching the
engine. Disconnect the fuel lines at the carburetor. Place a jar or CliP
under open line and briefly "crank" the engine by means of the
starter. If fuel spurts from the line, you may assume that the FUEL
LINES are dear and the FUEL PUMP is operating properly. If no fuel
leaves the line, either the fuel lines or fuel pump are at fault. See
your Authorized Chevrolet Dealer.
(C) Before reconnecting the fuel lines to the carburetor, remove
the
FUEL FILTER from carburetor inlet and check its condition.
If it appears to be clean, replace it.and reconnect the fuel lines. If
the filter appears to be plugged, clean it as well as possible by
scraping out the foreign material and cleaning in a solvent. Then
r~install the filter and repeat the procedure with the second carbu­
r~ior. Replace the filters with new ones as soon as possible .
(0) If the fuel seems to be reaching the carburetors properly, the
problem may
be: an EMPTY CARBURETOR BOWL caused by a
"stuck shut" float valve or a FLOODED CARBURETOR caused by a
"stuck open" condition and evidenced by gasoline flowing down
the outside of the carburetor; or a stuck CHOKE valve. Remove the
air cleaners from the carburetors. Check that the choke valves move
freely and are not stuck. Tap the side of the carburetors sharply
several times with a light tool such as a screwdriver handle or pliers.
Replace the air cleaners and attempt to start the engine in the
normal manner.
(E) If the car will start but stalls when hot or has a rough idle,
you can suspect a faulty IDLE ADJUSTMENT, or extremely dirty

Downloaded from www.Manualslib.com manuals search engine and blocked AIR CLEANER ELEMENTS. Clean and reoil the air
cleaner elements if necessary. Idle adjustment should be performed
by your Chevrolet Dealer.
If the above Fuel System checks and the checks suggested under
the Electrical System following do not correct the malfunction, it is
recommended that you turn to your Authorized Chevrolet Dealer
for further checks , adjustments or repairs.
ELECTRICAL SYSTEM
If, when the ignition key is turned to START, the engine will not
turn
over, you have good reason to suspect electrical trouble.
(F) When there .is no response at all to attempts to start the car,
check the obvious-your AUTOMATIC TRANSMISSION SElECTOR
LEVER must be in neutral position before the engine can be started.
Turning the IGNITION SWITCH rapidly back and forth several
times will sometimes correct a poor internal switch contact.
(G) The
BATTERY may be discharged. If so, lights will be dim and
the horn will have a poor tone if it will blow at all.
Usually a
garage recharge will be necessary to return the battery
to operation. Occasionally, however , a push start and a long drive
will
recharge the battery.
NOTE : If the battery is determined to be dead, and for no apparent
reason , have your Authorized Chevrolet Dealer check the
battery, the GENERATOR and the VOLTAGE REGULATOR .
GENERA TOR trouble should already have been indicated by
the indicator on the instrument panel. Never remove generator
"BAT" lead without first disconnecting battery ground cable.
49
POOR BATTERY CONNECTIONS may be suspected if the car has operated properly a short time before and now not even the horn
will operate. Check both ends of both battery cables. If the con­
nections are corroded, a car may sometimes be restored to opera­
tion by removing all cable ends, scraping all contacting surfaces clean with a pen knife , and reassembling . If the cables are broken, they must be replaced. The power supply should now be restored unless the battery is dead.
(H) If, however, the lights and horn work properly but the starter will still not turn over, check the STARTER connections. A "click" from the starter solenoid indicates that the wiring to the starter is properly installed . If the wiring seems to be clean and tightly in­stalled, the trouble is probably in the starter itself and should be referred to your Authorized Chevrolet Dealer.
When the engine will "turn over" but will not start, the following
items may be checked along with Fuel System Checks listed
previously .
(I) With a clean dry cloth wipe the ceramic portions of the spark plugs dry. In particularly damp or rainy wellthe'r dampness may be the cause of not starting, especi-: . ally when the engine is cold.
(J) Check the cables at the top of the distributor and coil as well as each spark plug cable for tightness.
(K) If the car will still not start, check for spark at the spark plugs in the following manner:
Pull
one of the spark plug
wires off its spark plug. Insert a
short piece of bare wire (such as a bobby pin) between the rubber Oislribulor and Coil Leads
