1974 CHEVROLET CAMARO radiator cap

Downloaded from www.Manualslib.com manuals search engine tory with a high-quality, inhibited,
year-around coolant that meets the
standards of General Motors
Spe­
cification 1899-M. This coolant
solution provides freezing protec­
tion to
-20oP (-35°P in Can­
ada), and it has been formulated to
be used for two full calendar years
or
24,000 miles, whichever first
occurs, of normal operation with­
out replacement, provided the
proper concentration of coolant is
maintained.
Cooling System Care
The radiator cap should not be
removed to check coolant level.
Check the coolant level visually in
the 'see thru' coolant recovery tank
at least
as frequently as engine oil
changes. Level should be at the
"full cold" mark on the recovery
tank when the system
is cold. At
normal operating temperature the
coolant should be at the
"full hot"
mark on the recovery tank. Add sufficient
coolant to the recovery
tank.
Use a 50/50 mixture of high­
quality ethylene glycol antifreeze
and water for coolant additions.
If
regular additions are required, see
your dealer for a cooling system
check.
NOTE: If recommended quality
antifreeze
is used, supplemental in­
hibitors or additives claiming to
provide increased capability are
not necessary. They may be detri­
mental to the efficient operation of
the system, and represent an un­
necessary operating expense.
Every year, the cooling system
should be serviced
as follows:
1. Wash
radiator cap and filler
neck with clean water.
2. Check coolant for proper level
and freeze protection.
3. Pressure test system and radia-
54
tor cap for proper pressure hold­
ing capacity (15 psi) .
If re­
placement of cap
is required, use
the special AC cap designed for
coolant recovery systems, speci­
fied for your model.
4. Tighten hose clamps and inspect
all hoses. Replace hoses when­
ever swollen, checked or other­
wise deteriorated.
5. Clean frontal area of radiator
core and air conditioning con­
denser.
Replace hoses every 24 months
or 24,000 miles or earlier if
checked, swollen or otherwise de­
teriorated. Every two years
or 24,-
000 miles, whichever first occurs,
the cooling system should be
flushed and refilled using the fol­
lowing recommended procedure:
1. Remove radiator cap when
engine is cool by:
• Slowly rotating cap counter-

Downloaded from www.Manualslib.com manuals search engine clockwise to detent (do not
press down while rotating).
• Wait until any residual pres­
sure (indicated by a hissing
sound)
is relieved.
• After all hissing ceases, press
down on cap while continuing
to rotate counterclockwise.
CAUTION: To ,a~()/d' thedange, .• olbfling "l)~ned;tlo n(Jtl'entoveradiator «aP while
, engipe and radiator are ,stlll hot because $ca/ding ' flU./d·antlsteam' will be blown .
(1utunder pressure.
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
fill system .
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
to the base of the radiator filler
55
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
of filler neck and install radia­
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 temperatures are not expected.
• Add ethylene glycol base coolant
that meets GM Specification
1899-M when coolant additions
are required because of coolant
loss or to provide additional pro­
tection against freezing at tem­
peratures lower than
-20°F
(-35°F in Canada).
NOTE: Alcohol or methanol base
coolants or plain water are not
recommended for your Camaro at
any time.
Radi~tor Pressure Cap
The radiator cap, a 15 lb. pres­
sure type, must be installed tightly,
9therwise coolant may be lost and
damage to engine may result from
overheating.
Radiator pressure
caps should be checked periodi­
cally for proper operation.
If re­
placement
is required specify AC.
Thermostat
The cooling system is protected
and controlled by a thermostat in­
stalled in the engine coolant outlet
to maintain a satisfactory operat­
ing temperature of the engine. This

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.
