CHEVROLET CAMARO 1974 2.G Workshop Manual

Downloaded from www.Manualslib.com manuals search engine provide excellent engine pro­
tection.
See your Chevrolet dealer for ad­
vice on the frequency of oil and
filter changes under unusual driv­
ing conditions.
The above recommendations ap­
ply to the first change
as well as
subsequent oil changes. The oil
change interval for your Camaro
engine
is based on the use of SE oils
and quality oil filters.
Oil change in­
tervals longer than those listed
above will seriously reduce engine
life and may affect Chevrolet obli­
gation under the provisions of the
New Vehicle Warranty.
A high quality SE oil was in­
stalled in your engine at the fac­
tory. It
is not necessary to change
this factory-installed oil prior to the
recommended normal change pe­
riod. However, check the oil level
more frequently during the break­
in period since higher oil consump- tion
is normal
until the piston rings
become seated.
NOTE: Non-detergent and other
low quality oils are specifically
Recommended Viscosity
not recommended. Only the use
of
SE engine oils and proper oil
and filter change intervals assure
you of continued proper lubrica­
tion of your Camaro engine.
Select the proper oil viscosity from the following chart:

cosity oil is recommended for all seasons in vehicles normally operated in
Canada.
The proper oil viscosity helps assure good cold and hot startfng.

Downloaded from www.Manualslib.com manuals search engine Checking Oil Level
The engine oil should be main­
tained at proper level. The best
time to check it
is before operating
the engine or
as the last step in a
fuel stop. This will allow the oil ac­
cumulation in the engine to drain
back in the crankcase.
To check
the level, remove the oil guage rod
(dip stick), wipe it clean and rein­
sert
it firmly for an accurate read­
ing. The oil gauge rod
is marked
"FULL" and "ADD." The oil level
should be maintained in the safety
margin, neither going above the
"FULL" line nor below the "ADD"
line. Reseat the gauge firmly after
taking the reading.
Supplemental Engine Oil
Additives
The regular use of supplemental
additives
is specifically not recom­
mended and will increase operat­
ing costs. However, supplemental additives
are available that can
effectively and economically solve
certain specific problems without
causing other difficulties.
For ex­
ample, if higher detergency
is re­
quired to reduce varnish and
sludge deposits resulting from
some unusual operational diffi­
culty, a thoroughly tested and ap­
proved additive -
"Super Engine
Oil Supplement" -is available at
your Chevrolet dealer.
In the event
of an operational problem, consult
your dealer for advice before
us­
ing supplemental additives.
Drive Belts
Every 6,000 miles or 4 months­
inspect drive belts for wear , fray­
ing, cracking , and tension. Belts
which are in poor condition should
be replaced immediately.
Check tension by applying mod­
erate thumb pressure midway be­
tween pulleys.
If the center-to-
49
center distance between pulleys is
13 to 16 inches, the belt should
deflect
1;2 inch . If the center-to­
center distance
is 7 to 10 inches,
the belt should deflect
1;4 inch.
Loose belts should be retensioned
to give the correct deflection.
It is recommended that belts be
replaced every 24 months or
24,000
miles , whichever occurs first.

Automatic Transmission
Fluid Recommendations
Use only automatic transmis­
sion fluids identified with the
mark
DEXRON@ II or DEX­
RON®. These fluids have been spe­
cially formulated and tested for use
in your automatic transmission,
and are available from your Chev­
rolet dealer or local service station.
Check the fluid level at each
engine oil change period. To make
an accurate fluid level check:
Check the fluid level at each en­
gine oil change period.
To make an
accurate fluid level check:

1. Drive car several miles, making
frequent starts and stops, to
bring transmission up to normal
operating temperature (approxi­
mately
180-190° F.).
2. Park car on a level surface.
3. Place selector level in "Park"
and leave engine running.
4. Remove dipstick and wipe clean.
S . Reinsert dipstick until
cap seats.
6. Remove dipstick and note read­
ing.
If fluid level is at or below the
ADD mark, add sufficient fluid to
raise the level to the
FULL mark.
One pint raises the level from ADD
to FULL.
Do not overfill.
Under normal driving condi­
tions, the transmission fluid should
be changed every 24,000 miles. If
your car is driven extensively in
heavy city traffic during hot weather,
or
is used to pull a trailer , change
fluid every
12,000 miles. Likewise,
operators of cars in commercial use

Downloaded from www.Manualslib.com manuals search engine (such as taxicab, limousine or pa­
trol car service) where the engine
idles for long periods, should
change fluid every
12,000 miles.

pivot points in release mecha­
nism,
as well as primary and
secondary latch mechanisms.
4. Lubricate hood hinges.
5. Make hood hinge and latch
mechanism functional check to
assure the assembly
is working
correctly.
Air Conditioning
Have your Chevrolet Dealer
check your Air Conditioning
sys­
tem at some time during the winter
months to
be sure there has been
no loss in cooling output. During
the summer,
see your Chevrolet
Dealer immediately if you suspect
the system
is not performing as it
should.

NOTE: On vehicles equipped
with a Four Season Air Condi­
tioning System, the system will not
operate below ambient tempera­
tures of
30°F. regardless of con­
trol position.
Cooling System Care
Check the coolant level at each
engine · oil change.
Engine Cooling System
The recovery type cooling sys­
tem is standard on all Chevrolet
passenger cars and
is designed to
maintain the engine at proper op­
erating temperatures.
The recovery
tank collects coolant that expands
with rising temperature that would
otherwise overflow from the
sys­
tem. When · the system temperature
drops, the coolant
is drawn from
the recovery tank back into the
radiator by the suction created by
coolant contraction. The cooling
system has been filled at the fac-

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.

(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
