2. If necessary, run engine, with
radiator cap removed, until nor­
mal operating temperature
is
reached and upper radiator hose
is hot (indicates thermostat
is
open).
3. Stop engine and open radiator
drain valve to drain coolant. (To
speed this operation, the drain
plugs in the block can also be
removed.) 4.
Close valve (install block drain
plugs, if removed) and add suf­
ficient water to

5. Run engine, drain and refill the
system, as described in steps
1,
2, 3, and 4, a sufficient number
of times until the drained liquid
is nearly colorless.
6. Allow system to drain com­
pletely and then close radiator
drain valve tightly. (Install
block drain plugs, if removed.)
7. Remove recovery cap leaving
hoses in place. Remove coolant
recovery tank and empty of
fluid. Flush tank with clean
water , drain and reinstall.
8. Add sufficient ethylene glycol
coolant , meeting GM specifica­
tion 1899-M, to provide the re­
quired freezing and corrosion
protection-at least a 44 percent
solution
(-20°F). Fill radiator

neck and add sufficient coolant
to the recovery tank to raise level
to the
"FULL HOT" mark. Re­
install recovery tank cap.
9. Run engine , with radiator cap
removed, until normal operat­
ing
temperature is reached.
(Radiator upper hose becomes
hot.)
10. With engine idling, add cool­
ant until level reaches bottom

tor cap making certain arrows
line up with overflow tube.
It is the owner's responsibility
to keep the freeze protection at a
level commensurate with the tem­
peratures which may occur in the
area of vehicle operation .
• Maintain cooling system freeze
protection at
-20 °F or below
to ensure protection against cor­
rosion and loss of coolant from
boiling even though freezing

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 insp~ct the vehicle and make whatever repairs or adjustments are necessary.

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 "flooding" of the carburetor is evidenced by a carburetor wet with
fuel or black exhaust smoke,
perform the operation sug­
gested in paragraph D only .
(A) The first and most obvious, and one of the most frequently Checking Fuel Flow
67
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.
(B) If the fuel tank is not empty, you may check further to see 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 carbu retor
inlet and check its condition . If it
appears to be clean, replace it
and reconnect the fuel line. Re­
place the filter if it appears to be plugged.
(0) 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
•

Downloaded from www.Manualslib.com manuals search engine valve moves freely and is not stuck . (Don 't mistake normal spring
tension for a stuck valve.) Top 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. IE) If the cor will start but stalls when hot or has a rough idle,
you can suspect a faulty IDLE ADJUSTMENT, a malfunctioning AUTOMATIC CHOKE or on 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
baHery ground cable.
, (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 or Park position (manucil 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. (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 bottery to operation. Occasionally, however, a long drive will recharge the battery.
68
NOTE: If the battery is determined to be dead, and for no apparent reason, have your Authorized Chevrolet Dealer check the
baHery, the GENERATOR and the VOLTAGE REGULATOR.
GENERATOR trouble should already have been indicated by the generator indicator light on the instrument panel.
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 con­nections are corroded, a cor 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.
(H) If, however, the lights and horn work properly but the starter will still not turn over, check the STARTER connections. A "dick" 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 the Fuel Systems Checks listed
previously.
(I) 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 starting, espe­cially when the engine is cold.
(J) Check the cables at the top of the distributor and coil as well Distributor and Coil Cables

Downloaded from www.Manualslib.com manuals search engine as each spark plug cable for
tightness.
(K) 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 a bobby pin) between the rubber
cup
at the end of the spark plug
wire
and the tubular metal con­nector inside of it. If the spark
plug wire is wet or oily, wipe it Checking Spark
dry. Wrap a dry handkerchief or facial tissue, folded several
thicknesses, around the wire at least three inches back from the
end and grasp the wire at this point. Hold the bare wire about 1f ..
inch from the bare tip of the spark plug from which you removed the
wire. When the engine is "turned over" a spark should jump across
the
~ inch space, indicating ample current supply. If no spark
jumps, the difficulty
is probably caused by a defective ignition part
and should be corrected by your Authorized Chevrolet Dealer.
COOLING SYSTEM
When the car 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 whim the OIL LEVEL falls danger­ously low. Check the oil level as a matter of course.
69
(M) Low COOLANT LEVEL will, of co~rse, cause engine over­
heating. 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.
(0) Condition of the FAN BELT is very impartant, 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.
(P) Another cause of engine
overheating may be an inopera­
tive COOLING SYSTEM THERMO­STAT. If the thermostat should fail in the closed position, it will not
permit 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.

FUSES AND CIRCUIT BREAKERS
The wiring circuits in your 1974 Camaro
are protected from short circuits by a combi­
nation of fuses, circuit breakers, and fusible
thermal
linkS in the wiring itself. This greatly
reduces the hazard of electrically caused fires
in the automobile. The fuse junction block
is
located under the left side of the instrument
panel.

The head lamp circuit s are protected by a circuit breaker in the light switch.
An electrical overload on the breaker will cause the lamps to go on and off, or
in some cases to remain off. If this condition develops, have your wiring circuits checked immediately.

An Air Conditioning high blower speed fuse, 30 amp. is located in an
In-line fuse holder running from junction block to Air Conditioning relay.
Do not use fuses of higher amperage rating than those recommended above.
Fusible Links are incorporated into the wiring system. These are wires of such a gauge that they will fuse (or melt) before damage occurs to an entire
wiring harness in the event of an electrical overload. See your Chevrolet Dealer if fusible link replacement becomes necessary.
