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.

(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.

but should be replaced with a properly functioning thermostat as soon as possible.

FUSES AND CIRCUIT BREAKERS
The wiring circuits in your 1973 Camaro
are protected from short circuits by a
combin
ation 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.

Downloaded from www.Manualslib.com manuals search engine FUSES AND CIRCUIT BREAKER:
The headlamp circuit is 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. Where current load is too heavy, the circuit breaker intermittently opens and closes, protecting the circuit until the cause is found and eliminated.
Fuses, located in the Junction Block beneath the dash on the driver's side are:

An Air Conditioning high blower speed fuse,30 amp. is located in an In·line fuse holder running from horn relay 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.
