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.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE. OF.
NOTE: SAE 5W-20 oils are not recommended for sustained high-speed
driving.
SAE 30 oils may be used at temperatures above 40°F.
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
Page 58 of 88

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
originally installed position.
Re
place element at 24,000, miles.
Element must not be washed,
oiled, tapped or cleaned with an
air hose.
Crankca.e Ventilation Filter
(located within Air Cleaner)
If so equipped, inspect at every oil
change and replace if necessary.
Replace at least every
24,000
miles; more often under dusty
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.
Replace in-line filter every
24,000 miles.
When replacement
is necessary,
always insist on AC Acron filters.

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.

Coolant Recommendations
The inhibited year-around cool
ant, used to
fill the cooling system
at the factory,
is a high quality so
lution that meets General Motors
Specifications 1899-M. This fac
tory-fill coolant solution
is formu
lated to withstand two full calendar
years of normal operation without
draining, provided the same con
centration of coolant
is added if the
system needs additional fluid be
tween drain periods. The original
factory-fill coolant provides freez
ing protection to
-20°F (-32°F
in Canada).
Every two years, the cooling sys
tem should be serviced as follows:
1. Drain coolant, when hot,
through the radiator drain valve.
2. Close valve and add sufficient
plain· water to
fill system.
3. Run engine until normal operat
ing temperature
is reached.
4. Drain and refill the system as
described in steps 1, 2, and 3 a
sufficient number of times until
the drained liquid
is colorless.
5. Allow system to drain com
pletely and then close radiator
drain valve tightly.
6.
Add the necessary amount of
high quality inhibited glycol
base coolant meeting GM
Speci
fication 1899-M to provide the
required freezing and corrosion
protection
(at least to O°F.)
7. Run engine until normal oper
ating temperature
is reached.
8. Check and adjust level of cool
ant after system has cooled
suffi
ciently to remove radiator cap.
60
NOTE: Addition of supplemental
additives and other available ma
terials which have not been specifi
cally approved by GM are not nor
mally required in your car. Use of
these materials will result in un
warranted operating expense.
It is the owner's responsibility to
keep the freeze protection at a level
commensurate with the tempera
tures which may occur in the area
in which the vehicle will be oper
ated. Regardless of whether freez
ing temperatures are
or are not ex
pected, cooling system protection
should be maintained at least to
OaF to provide adequate corrosion
protection. When coolant addi
tions are required because of cool
ant loss or to provide additional
protection against freezing at tem
peratures lower than
-20°F,
(-32°F in Canada), a sufficient
amount of an ethylene glycol base
Page 64 of 88

Downloaded from www.Manualslib.com manuals search engine • coolant meeting GM Specification
1899 M should be used.
NOTE: Alcohol or methanol base
coolants or plain water are not rec
ommended for your Camaro at
any time.
Radiator Pressure Cap
The radiator cap, a 15 lb. pres
sure type, must be installed tightly,
otherwise 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
thermostat
is designed for continu
ous use through both winter and
summer and need not be changed
seasonally. When replacement
is
necessary, specify United Delco
parts.
Tires
The factory installed tires on
your car are selected to provide the
best all around tire performance
for all normal operation. When in
lated
as recommended in the tire
inflation placard affixed to the left
door of your vehicle, they have the
load carrying capacity to operate
satisfactorily at all loads up to and
including the full rated load speci-
61
fied in that table at all normal high
way speeds. In addition, for those
owners who prefer the utmost in
comfort, optional tire inflation
pressures may be used when loads
of four passengers or less are
carried.
For the added convenience of
owners, many Chevrolet dealers
are equipped to handle tire war
rantyadjustments on certain makes
of tires provided on 1971 Chevro
let cars.
TIRE TRACTION
A decrease in driving, corner
ing, and braking traction occurs
when water, snow, ice, gravel, or
other material
is on the road sur
face. Driving practices and car
speed should be adjusted to the
road conditions.
