Optional Instruments and Gauges
Tachometer and Oil Pressure Indicator Light
The optional Tachometer indicates the speed of the engine in revolutions per
minute . The yellow are'a on the face of the tachometer indicates the highest recom­
mended engine rpm. Engine operation causing tachometer indications in
or above
the red area can lead to serious engine damage.
Function of the oil pressure light
is described on page 23.
Engine Temperature Gauge
This optional gauge indicates coolant temperature which will vary with air tem­
perature and operating conditions. The ignition switch must be on for accurate
readings. Hard driving or prolonged idling in very hot weather will cause the pointer
to move beyond the center of the band. Should pointer move to the line at the
"H"
end of the band, stop engine or reduce speed to permit engine to cool. With Air
Injection Reactor System, the needle will frequently move beyond the center of the
band.
Ammeter
The optional ammeter indicates whether the battery is being charged or discharged.
The Delcotron charging system
is equipped with a regulator which controls the charge
according to battery requirements. When the Delcotron generator
is supplying more
than the current demand, the ammeter will indicate a charging rate.
If the current
demand
is more than the Delcotron output, a discharge will be indicated. With the
battery fully charged, the charging rate will be low, thus giving an indication of
battery condition.

switch
is on.
With the side windows closed,
outside air flow into the front
grilles, through the car and out the
rear air exhaust valves.
Basic Operating Tips:
• Always keep front inlet grille
clear of obstructions (leaves,
ice, snow, etc.).
• When heating or air condition­
ing
is desired, best comfort is at­
tained by driving with all the
windows closed.
The following sections of this
manual provide additional operat­
ing tips for obtaining maximum
heating and cooling comfort.
(See
also Engine Exhaust Gas Caution
at beginning of this Section.)

Air Vents
The air vents in each kick panel
admit air from the vent grille just
ahead of the windshield. Control
knobs open and close the vents.
The amount of air entering the
car through this system
is depend­
ent upon vehicle speed.
Four Season Air Conditioning
equipped cars have no kick panel
vents since the vents are a part of
the air conditioning system.

The optional Tape Player provides
prerecorded programs for your en­
joyment.
To play, turn ignition switch to
"ON" or "AC" position and insert
cartridge through tape door with
label side up and open end
in first.
Tape will play through all four pro­
grams in succession, then replay in
same sequence. Balancing the
speakers is not required as this ad­
justment has been made at the fac­
tory. Should it become necessary
to make this adjustment, see your
Chevrolet dealer.
1. Rotate fader control until volume
from front and rear speakers
sounds eq ual. 2.
Regulate volume control and
tone controls
as desired.
3.
To change program track, push

capstan (revolving metal post), head
and tape guide should be cleaned
with a cotton-tipped swab moist­
ened with alcohol (do not use car­
bon tetrachloride).
To clean the
capstan, trip the on-off switch at
the rear of the receptacle with
your finger and hold the swab
against the rotating capstan.

Four Way Hazard
Warning Flasher
• Use the warning flasher to warn
other drivers any time your
ve·
hicle becomes a traffic hazard,
day or night.
• Avoid stopping on the roadway
if possible.
• Turn on the hazard warning
flasher
by pushing in on the

button located on the column
just below the steering wheel.
Flasher can be actuated with
engine ignition either off or on.
• If the brake pedal is depressed,
the lights will not flash but glow
continuously instead.
• To cancel the flasher, pull the
button out.
Freeing Car From Sand, etc.
If it becomes necessary to rock
the car to free it from sand, mud
or snow, move the selector lever
on automatic transmission models

For best possible trac­
tion, avoid spinning wheels when
trying to free the car. The use of
AC Liquid Tire Chain is recom­
mended for temporary assistance
when traction
is lost on ice or snow.
Towing
Proper lifting or towing equip­
ment is necessary to prevent dam­
age to the vehicle during any tow­
ing operation. State (Provincial in
Canada) and local laws applicable
to vehicles in tow must also be
fol­
lowed . Chevrolet dealers can ad­
vise you on the selection of a

Your Camaro may be towed on
all four wheels, at speeds of
less
than 35 mph, for distances up to
50 miles, provided driveline, axle
and transmission are otherwise
normally operable. For such tow­
ing, parking brake must be re­
leased, transmission must be in
neutral
and ignition lock turned to
OFF position. Attachments must
be to main structural members of
the car, not to bumpers or brac­
keting. Separate safety chains
or
cables should be used. Remember
that power brake and steering
as­
sists will not be available when
engine
is inoperative.
Emergency Starting
• Never tow the car to start be­
cause the surge forward when
the engine starts could cause a
collision with the tow vehicle.
• Engines in vehicles with auto­
matic transmissions cannot be
started by (towing
or) pushing
the car.
• To start the car when the Ener­
gizer (battery)
is discharged,
use a single auxiliary battery or
Energizer of the same nominal
voltage
(12 volts) as the dis­
charged battery, with suitable
jumper cables.
• Make connections as set forth
below under
"Jump Starting
with Auxiliary (Booster) Bat­
tery" to lessen the chance of
personal injury
or property
damage.
Jump Starting with
Auxiliary (Booster) Battery
Both booster and discharged
battery should be treated carefully
when using jumper cables. Follow
37
exactly the procedure outlined be­
low, being careful not to cause
sparks:
1. Set parking brake and place
automatic transmission in
"PARK" (neutral for manual
transmission). Turn
off lights,
heater and other electrical loads.
2. Remove vent caps from both
the booster and the discharged
batteries. Lay a cloth over the
open vent wells of each battery.
These two actions help reduce
the explosion hazard always

Downloaded from www.Manualslib.com manuals search engine 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 car. The chart, designed to point out
possible solutions to several
of the most common automotive mal­functions 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 an Authorized Chevrolet Dealer inspect the vehicle and make whatever repairs or adjustments are necessary.
FUEL SYSTEM AND ENGINE
If the ignition switch will cause the engine to "turn over" or
"crank" but the car will not start, check Steps A through 0 below.
NOTE: If continual ··f1ooding··, 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 car is the amount of fuel in the
tank. Make it a habit to check the
FUEL GAUGE regularly and most
especially at a time when the en­gine will "turn over" but will not
start.
(8)
If the fuel tank is not empty,
you may check further to see
Checking Fuel Flow
63
whether the fuel is reaching the carburetor. Disconnect .the fuel line at the carburetor and remove the center wire (ground the secondary coil terminal or disconnect the primary wire from the coil to the
distributor at the coil) from the coil tower. Place a jar or cup under
the open line and briefly "crank" the engine by means of the
starter. If fuel spurts from the fitting, you may assume that the FUEL LINES are clear 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
line to the carburetor, remove
the
FUEL FILTER from the carburetor
inlet and check its condition. If it
appears to be clean, replace it
and recorinect the fuel line. Re­
place the filter if it appears to be
plugged.
(D) If the fuel seems to be
reaching the carburetor properly, Fuel Filter
the problem may be: an EMPTY CARBURETOR BOWL caused by a "stuck shut" carburetor; a FLOODED CARBURETOR caused by a "stuck open" condition and evidenced by gasoline seeping around and down the outside of the carburetor; or a stuck CHOKE valve.
Remove the air cleaner from the carburetor. Check that the choke
valve moves freely and is not stuck. (Don't mistake normal spring
tension for a stuck valve.) Tap the side of the carburetor sharply
several times with a light tool such as a screwdriver handle or pliers. Replace the air cleaner and attempt to start the engine in the normal manner.
I

Downloaded from www.Manualslib.com manuals search engine IE) If the car will start but stalls when hot or has a rough idle,
you can suspect a faulty IDLE ADJUSTMENT, a malfunctioning AUTOMATIC CHOKE or an extremely dirty and blocked AIR CLEANER ELEMENT. Replace paper element air cleaner if neces­sary. Idle adjustment or automatic choke service (other than that outlined in paragraph 0 above) 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 return 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. NOTE: Never remove Delcotron bat lead without first disconnecting
battery ground cable.
IF) 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 or Park position (manual transmission
must have clutch depressed all the way to floor) before the engine can be started. Turning the IGNITION SWITCH rapidly back and forth several times will sometimes correct a poor internal switch
contact.
IG) The BATIERY 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 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.
GENERATOR trouble should already have been indicated by the generator indicator light on the instrument panel.
64
POOR BATIERY 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 con­nections are corroded, a car may sometimes be restored to opera­tion 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.
IH) 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 in­
stalled, 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 foilowing
items may be checked along with the Fuel Systems Checks listed
previously.
II) With a clean dry cloth, wipe the ceramic portions of the spark plugs dry. In particularly damp or rainy weather dampness may be
the cause of not sta rting, especi­
ally when the engine is cold.
IJ) Check the cables at the top of the distributor and coil as well as each spark plug cable for
tightness.
IK) If the co r will still not sta rt,
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 Di.,ribu'or and Coil Cab I ••

Downloaded from www.Manualslib.com manuals search engine a bobby pin) between the rubber
cup at the end of the spark plug
wire and the tubular metal con­
nector inside of it. If the spark
plug wire is wet or oily, wipe it
dry. Wrap a dry handkerchief or facial tissue, folded several thick.
nesses, around the wire at least three inches back from the end
and grasp the wire at this point.
Hold the bare wire about 1f4 inch
from the
bare tip of the spark
plug from which you removed the Checking Spark
wire. When the engine is "turned over" a spark should jump across
the V" inch space, indicating ample current supply. If no spark
jumps, the difficulty is probably caused by a defective ignition port
and should be corrected by your Authorized Chevrolet Dealer.
COOLING SYSTEM
When the cor will run but evidences serious overheating on the temperature gauge in the instrument panel, there are several items
which may be checked .
(L) Engine overheating will occur when the OIL lEVEL falls danger­ously low. Check the oil level as a matter of course.
(M) Low COOLANT LEVEL will , of course, couse engine over­heating. Determine . the cause of the low coolant level and have
it corrected if necessary.
(N) Check the RADIATOR CORE. Clean it if it is plugged with
bugs, leaves or other foreign material.
65
(0) Condition of the FAN BELT is very important, not only for en­gine cooling but also for proper generator operation. Check the
condition of the belt. Replace it if it is worn or frayed. Loosen the generator toward the engine to remove and replace the belt. Tighten the belt, whether new or old, by loosening the generator bolts, prying with a bar on the generator until the belt is ten­sioned properly, then retighten
the generator bolts.
(PI Another couse of engine ove rheating may be on inopera­
tive COOLING SYSTEM THERMO­STAT. If the thermostat should foil in the closed position, it will not
perm it coolant to circulate through
the system . In such on emergency the thermostat may be removed
but should be replaced with a properly functioning thermostat as soon as possible.
