OPERATION: The Air Injection Reactor system,
(used on vehicles not equipped with
CCS) is de­
signed to reduce air pollution by oxidizing (burning)
the hydrocarbons and carbon monoxide after they
45
leave the combustion chamber. A positive displace­
ment air pump, driven by the engine, compresses
filtered air which
is injected at the exhaust port of
each cylinder. This air mixes with the exhaust gases
and promotes further oxidation of both hydro­
carbons and carbon monoxide. The
AIR system also
includes a specially calibrated carburetor and dis­
tributor.
MAINTENANCE: Complete effectiveness of this
system
is dependent on the engine idle speed,
ignition timing and
dwell being set according
to specifications as indicated on a label under
the hood. These adjustments should be
checked at the first oil change (4 months or
6,000 miles, whichever comes first). Subse­
quent checks should be made at 12 months or
12,000 mile intervals, whichever comes first.
These adjustments are
also included as part of
the
quality tune-up recommended at the same
intervals. In addition, all hoses and fittings
should be inspected to make sure they are
properly connected, and the drive belt in­
spected for wear
and tension on the 12 month
or
12,000 mile schedule.

Downloaded from www.Manualslib.com manuals search engine NOTE: If this cap requires a re­
placement, only· a cap with these
same features should be used. Fail­
ure to use the correct cap can re­
sult in a serious malfunction of the
system. Correct replacement caps
may
be obtained from your Au­
thorized Chevrolet Dealer.
Engine Oil
Recommendations
Use only engine oil which meets
oil quality standard GM 6041-M.
High quality oils which are in­
tended for service
MS and pass car
makers' tests are
of this quality.
The oil change interval (see para­
graph entitled
"Engine Oil Change
Interval") and the new vehicle
warranty are based on the use of
oils that meet these requirements.
NOTE: Non-detergent and other
low quality oils are specifically not
recommended. The use of proper
engine oils and oil change intervals are
your best assurance of contin­
ued reliability and performance
from your Camaro 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 evel, remove the oil gauge 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.
NOTE: The oil gauge rod is also
marked
"Use GM 6041-M Quality
MS Oil" as a reminder to use only
52
high quality oils as prescribed
under "Engine Oil Recommenda­
tions."
Supplemental Engine Oil
Additives
The regular use of supplemental
additives
is specifically not recom­
mended and will increase operat­
ing costs. However, in cases of spe­
cific problems which may arise
under certain conditions, additive
supplements are available that can
effectively and economically solve
these problems without causing
other difficulties.
For example, if
higher detergency
is required to re­
duce varnish and sludge deposits
resulting from some unusual opera­
tional difficulty, a thoroughly tested
and approved concentrate -
"En­
gine Oil Supplement"-is available
at your Chevrolet dealer.
It is sug­
gested that, in the event of
an oper­
ational problem, you consult your
dealer for advice.

Downloaded from www.Manualslib.com manuals search engine Engine Oil Change Interval
Change oil each 4 months. If
more than 6,000 miles are driven
in a 4-month period, change oil
each
6,000 miles.
In certain types of service in­
cluding:
• operation under dusty condi­
tions,
• trailer pulling,
• extensive idling, or
• short trip operation at freezing
temperatures (engine not
thor­
oughly warmed up),
the oil change interval should not
exceed 2 months, or
3,000 miles,
whichever occurs
first. Operation
in dust storms may require an im­
mediate change of oil. See your
Chevrolet dealer for advice on the
frequency of oil and filter changes under
unusual driving conditions.
The above recommendations
apply to the first change
as well as
subsequent oil changes. The oil
change interval for your Camaro
engine
is based on the use of oils
that
meet. the requirements indi­
cated in the section on "Engine Oil
Recommendations." Oil change in­
tervals longer than those listed
above will result in serious
reduc­
tion in engine life and may affect
Chevrolet's obligation under the
provisions of the
New Vehicle War­
ranty.
A high quality
MS oil meeting
General Motors Standard GM
6041-M was installed in your en­
gine at the factory. It is not neces­
sary to change this factory-installed
oil prior to the recommended
nor­
mal change period. However, the
oil level should
be checked more
frequently during the break-in pe­
riod since somewhat higher oil con-
53
sumption is normal until the piston
rings become seated.
Manifold Heat
Control Valve
Every 6,000 miles or 4 months,
check heat control valve for free­
dom of operation.
If shaft is stick­
ing free it up with GM Manifold
Heat Control Solvent or its equiva­
lent.
Engine
Oil Filter
Replacement
The engine oil filter should be
replaced at the first oil change and
every second oil change thereafter.
This recommendation
is based on
the use of engine oils that meet the
requirements indicated in the
sec­
tion on "Engine Oil Recommenda­
tions," and the use of a quality oil
filter. AC
Oil Filters provide maxi­
mum engine protection.

The following chart will serve as
a guide for selecting the proper oil
viscosity. The
proper viscosity helps assure
good cold and hot starting by re­
ducing friction and thus increasing
cranking speed.

Engine Tune-Up, Emission
Control and Electrical
System Checks
Fuel and electrical systems are
subject to wear and contamination
and require periodic cleaning and
adjustments to maintain maximum economy
and performance. Proper
adjustment of carburetor idle
speed, engine timing and dwell, and
operation of the Positive Crankcase
Ventilation Valve
(PCV) are im­
portant to control hydrocarbon
and
CO emissions within govern-
54
ment legislated levels. These ad­
justments should be made at the
first oil change
(4 months or 6,000
miles, whichever occurs first). The
above fuel and electrical system
checks also are included in engine
tune-ups which are recommended
at one year or 12,000-mile inter­
vals.
Air Injection Reactor (A.I.R.)
The Air Injection Reactor sys­
tem should have the A.I.R. pump
drive belt inspected for wear and
tension every 12 months or
12,000
miles, whichever occurs first.
Positive Crankcase
Ventilation
Valve
Replacement
Crankcase vapors and other im­
purities can cause malfunction of

Downloaded from www.Manualslib.com manuals search engine the crankcase ventilation valve.
Regular replacement of the PCV
Valve
is recommended at 24-month
or
24,000-mile intervals.
G.M. Evaporation
Control SYltem
The Evaporation Control System
requires only periodic canister filter
servicing.
Every 12 months
or 12,000
miles, whichever occurs first, (more
often under dusty conditions) the
filter in the base of the canister
must be replaced and the canister
inspected.
Drive Beltl
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
center distance between pulleys
is
13 to 16 inches, the belt should
deflect
lh 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.
Air Cleaner
Paper Ellment Type -First
12,000 miles, inspect element for
dust leaks, holes
or other damage,
replace
if necessary. If satisfac­
tory, rotate element
1800 from

driving conditions.
Flame Arrester -Every 12,000
55
miles-Clean the arrester (located
in the base of the air cleaner) with
kerosene
or a suitable solvent. Dry
with compressed air.
The engine air cleaner should
be installed at all times unless
temporary removal
is necessary
during repair or maintenance of
the vehicle, because in the absence
of the air cleaner backfiring could
cause
fire in the engine compart­
ment.
For maximum protection spe­
cify an AC Acron air filter ele­
ment.
Fuel Filter
Replace carburetor inlet filter
element every 12 months or
12,000 miles, whichever occurs
first or, if an in-line filter
is also
used, every
24,000 miles.
