1974 CHEVROLET CAMARO fuel

Downloaded from www.Manualslib.com manuals search engine Break-in Schedule
In addition to the new car
break-in instructions in this man­
ual, it
is recommended that your
new Camaro be operated for
500
miles before trailer towing. If it is
necessary to tow during this period,
avoid speeds over
50 MPH and full throttle
starts. The same precau­
tions should be observed whenever
a new engine, transmission
or axle
is installed in your car.
Operation in Foreign Countries
Your Camaro is designed to op­
erate on fuel of approximately
91
research octane number or higher,
sold in the United States and Can­
ada.
If you plan to operate your
Camaro outside the continental
limits of the United States
or Can­
ada, there
is a possibility that the
best fuels available in some coun­
tries are so low in anti-knock
quality that excessive knocking
and serious engine damage may
. result from their use. To obtain
information on the quality of fuels available
in the countries in which
you plan to travel , write to Chevro­
let Motor Division, Service Depart­
ment, Detroit, Michigan
48202,
(or in Canada write to General
Motors of Canada Limited,
Owner
Relations Department , Oshawa,
Ontario),
giving:
• The vehicle identification num­
ber ( on plate on instrument
panel ahead of the steering
wheel and visible through the
windshield , or from registration
slip or title).
• The country or countries in
12
which you plan to travel.
It
is recommended that you not
operate your Camaro in any coun­
try not having fuels meeting the
requirements of
your Camaro
engine. Engine modifications are
not available to compensate for
low anti-knock quality fuels. Op­
eration of your car under condi­
tions of continuous
or excessive
knocking constitutes misuse of the
engine and may cause engine dam­
age for which the Chevrolet Divi­
sion
is not responsible under the
terms
of the Chevrolet New
Vehicle Warranty.

Gas Cap-The fuel tank filler cap has
a new two-step removal and
installation procedure plus a pres­
sure-vacuum safety relief valve. It
is equipped with a double set of
locking tangs. To remove:
• Rotate cap one-half turn coun­
terclockwise to clear the first set
of tangs from the slots inside the
filler neck. This will allow any
residual pressure to escape.
• Pull the cap outward and rotate
one-quarter turn counterclock­
wise to clear second set of tangs
and remove the cap.
• To install, reverse this procedure.
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 and Filter
Recommendations
• Use only SE engine oil.
• Change oil each 4 months or
6,000 miles. If more than 6,000
miles are driven in a 4-month
period, change oil each
6,000
miles.
• Change oil each 2 months or
3,000 miles, whichever occurs
first, under the following con­
ditions: - driving in dusty conditions,
-trailer pulling,
- extensive idling,
- short-trip operation at freez-
ing temperatures (engine not

thoroughly warmed-up).
• Operation in dust storms may
require an immediate oil change.
• Replace the oil filter at the first
oil change, and every second oil
change thereafter. AC oil filters

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.

The use of improper tire
infla­
tion pressures can adversely affect
tire life and vehicle performance:
• Too little air pressure can result
in excessive tire heat, abnormal
tire wear, adverse handling and
reduced fuel economy.
• Too much air pressure can re­
sult in abnormal tire wear, ad­
verse vehicle ride and handling,
and increased susceptibility to
damage by road impacts.
Tire pressures should be
checked when the tires are "cold"
at least once a month (and pref­
erably oftener) or before long
trips or when heavily loaded. The
following points should
be ob­
served when checking and setting
tire pressures:
1. Cold tire pressure ratings are appli­cable when a vehicle has been Inopera­tive for 3 hours or more, or driven less
than 1 mile.
2. Tire Inflation pressure may Increase as
much as 6 pounds per square inch (psi)
when hot (aHer vehicle has been driven
10 miles or at speeds of more than 60 miles per hour). Do not "bleed" or re­duce pressures when tires are hot from
driving.
3. For continuous high speed operation
(over 75 mph), Increase tire inflation
pressure 4 psi above the recommended
pressures up
to a maximum of 32 psi
cold pressure for load range B tires, 36
psi for load range C tires, or 40 psi for D load range tires. Sustained speeds
above 75 mph are not recommended
when the 4 psi adjustment would re­quire pressures greater than the above
maximum pressures.
4. Always use a tire pressure gauge when
checking pressures as the appearance
of a tire can be deceiving. For example,
radial ply fires, In comparison with bias
ply tires at the same pressure, may have
the appearance of being under-inflated.
Vehicle Loading -Do not load
your vehicle beyond the vehicle
capacity (total pounds) shown on
the tire placard. This figure
repre­
sents the design capacity of the ve­
hicle, not merely of the tires.
58
When towmg trailers, the allow­
able pasenger and cargo load
must be reduced by an amount
equal to the trailer tongue load on
the trailer hitch.
(See "Trailer
Hauling"
in Section 1 of this man­
ual.) Station wagon loads should
be distributed
as far forward as
possible. Vehicles equipped with
luggage racks do not have a
ve­
hicle load capacity greater than
specified on the tire placard.
Tire Wear and Rotation -Un­
even or abnormal tire wear is usu­
ally the result of incorrect inflation
pressure, improper wheel
align­
ment, wheels being out-of-balance,
or poor driving habits.
Underin­
flation, incorrect toe or camber
and fast cornering produce
differ­
ent types of abnormal wear which
can be diagnosed by your dealer.

is not recommended.
Improper mounting can cause
vio­
lent bursting of the tire away from
the wheel which can result in serious
personal injury.
Underbody Maintenance
The effects of salt and other
corrosive materials used for ice
and snow removal and dust
con­
trol can result in accelerated rust­
ing and deterioration of under­
body components such
as brake
and fuel lines, frame, underbody
floor pan, exhaust system, brac­
kets , parking brake cables. These
corrosive effects, however, can be
reduced by periodic flushing of the underbody
with plain water. In
geographic areas having a heavy
concentration of such corrosive
materials,
it is recommended that
the complete underbody be
in­
spected and flushed at least once
each year, preferably after a
win­
ter's exposure. Particular attention
should be given to cleaning out
underbody members where dirt
and other foreign materials may
have collected.
If desired, your Chevrolet deal­
er can perform this service for
you.
In addition, he can provide
recommendations on undercoat­
ing materials which will help
pro­
tect your vehicle from corrosion.
