reminder to use only
SE oils.
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
center distance between pulleys
is
13 to 16 inches, the belt should
deflect
Y2 inch . If the center-to­
center distance
is7 to 10 inches,
the belt should deflect
1.4 inch.
Loose belts should be retensioned

Automatic Transmission
Fluid Recommendations
Use only automatic transmis­
sion fluids identified with the
mark
DEXRON. These fluids have
been specially formulated and
tested for
use in your automatic
transmission, and are available
from your Chevrolet dealer or lo­
cal 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.
49
4. Remove dipstick and wipe clean.
5. 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
(such as taxicab, limousine
or pa­
trol car service) where the engine
idles for long periods, should
change fluid every
12,000 miles.
Changing Fluid-For Turbo Hy­
dra-Matic
350, remove fluid from

Downloaded from www.Manualslib.com manuals search engine the transmission sump and add ap­
proximately 2.5 quarts U.S. Mea­
sure
(2.0 quarts Imperial Mea­
sure). Operate transmission
through all shift ranges and re­
check fluid level as described
above.

is important that the dip­
stick be pushed all the way into
the filler tube.
Every 24,000 miles -After re­
moving fluid from the transmission
sump, approximately
71h. pints
U.S. measure (6 pints Imperial
measure) of fresh fluid will be re­
quired to return level to proper mark

does not require periodic changing.
Hood Latches
Every 4 months or 6,000 miles,
whichever occurs first, lubricate
hood latch assembly and hood
hinge assembly
as follows:
1. Wipe off any accumulation of
dirt
or contamination on latch
parts.
2. Apply Lubriplate or equivalent
to latch pilot bolts and latch
locking plate.

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
52
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
Checking the coolant level at
each engine oil change. Level
should be
3" below bottom of filler
neck when cold.
Engine Cooling System
The standard and recovery type
cooling systems are designed
to
maintain the engine at proper op­
erating temperatures. The recovery
•

Downloaded from www.Manualslib.com manuals search engine type cooling system is used on all
1973 Camaro air conditioned and
heavy duty cooling systems. It has
been filled at the factory with a
high-quality, inhibited, year-around
coolant that meets the standards
of General Motors Specification
1899-M. This coolant solution pro­
vides freezing protection to
-20 0 F
(-32°F in Canada), and it has
been formulated to be used for
two full calendar years
or 24,000
miles, whichever first occurs, of
normal operation without draining,
provided the proper concentration
of coolant
is maintained.
• For Recovery Systems Only­
Check the coolant level visually
at the see-through coolant reser­
voir at each oil change interval
while the engine
is at normal
operating temperature. Do not
remove radiator cap except for
draining and refilling the system.
Coolant level should be at the
"Full Hot" mark on the reservoir.
If system is checked cold, the
coolant level should be at the
"Full Cold" mark on the reser­
voir.
• For Other Than Recovery Sys­
tems-Check the coolant level
only at oil change intervals, un­
less there
is evidence of leaking
or overheating. Do not remove
radiator cap when solution
is
hot and under pressure. Coolant
level should be a maximum of
three inches below the level of
the filler neck when the engine
is cold.
• All Systems-Add a 50/50 mix­
ture of high-quality ethylene
glycol antifreeze and water if
coolant additions are necessary.
Do not overfill.
NOTE: If recommended quality
antifreeze
is used, supplemental
inhibitors or additives claiming to
53
provide increased cooling capabil­
ity are not necessary. They may be
detrimental to the efficient opera­
tion of the system, and represent
an unnecessary 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
tor cap for proper pressure hold­
ing capacity (15 psi).
If re­
placement
of cap is required,
use the proper AC cap specified
for your car model.
4. Tighten hose clamps and inspect
all hoses. Replace hoses when­
ever checked, swollen
or other­
wise deteriorated.
5. Clean frontal area of radiator
core and air conditioning con­
denser.

Downloaded from www.Manualslib.com manuals search engine Every two years or 24,000 miles,
whichever first occurs, the cooling
system should be drained by si­
phoning
and refilled as follows :
1 . Run engine, with radiator cap
removed , until normal operat­
ing temperature
is reached
and upper radiator
is hot (in­
dicates thermostat
is open).
2. With engine stopped, insert
one end
of a 5-foot length of
¥s inch tubing into the filler
neck until it touches the bot­
tom of the radiator.
3. Insert any type of large sy­
ringe into the open end of the
tubing and initiate the siphon­
ing process by squeezing and
releasing the ball.
4. Completely drain radiator
coolant through the siphon
tube.
(To speed this opera­
. tion the drain plugs in block
can also be removed.)
4A. For recovery systems use
same method to siphon all
coolant from reservoir.
5. Remove tubing (install block
drain plugs, if removed) and
add sufficient water to fill
system.
6. Run engine, drain and refill
the system, as described in
steps
1 thru 5, a sufficient
number of times until the
drained liquid
is nearly color­
less.
7. Allow system to drain com­
pletely and install block drain
plugs, if removed.
8. Coolant Recovery Systems
Only
- Flush reservoir with
clean water,
and drain.
54
9. Add sufficient ethylene glycol
coolant, meeting
GM Specifi­
cation 1899-M, to provide
the required freezing and
corrosion
protection-at least
a
44 percent solution (-200
F). For both standard and
recovery systems, fill radiator
to the cold fill level
(3" be­
low bottom
of filler neck).
For recovery systems, add
sufficient coolant to reservoir
to raise level to
"Full Hot"
mark.
I O. Run engine, with radiator cap
removed, until normal oper­
ating temperature
is reached.
(Radiator upper hose be­
comes
hot.)
11. With engine idling, add cool­
ant to within 1 V:z " below bot­
tom of filler neck and install
radiator cap making certain
arrows line
up with overflow
tube.

Downloaded from www.Manualslib.com manuals search engine 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
_200 F or below
to ensure protection against cor­
rosion and loss of coolant from
boiling, even though freezing
temperatures are not expected.
• Add ethylene glycol base cool­
ant that meets GM Specification
1899-M when coolant additions
are required because of coolant
loss or to provide additional
protection against freezing at
temperatures lower than
_200
F (_320 F in Canada).
NOTE: Alcohol or methanol base
coolants
or plain water are not
recommended 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 thennostat
in­
stalled in the engine coolant outlet
to maintain a satisfactory operat­
ing temperature of the engine. This
thermostat
is designed forcontinu­
ous use through both winter and summer
and need not be changed
seasonally . When replacement
is
necessary, Delco parts are recom~
mended.
Tires
The factory installed tires on
your car
as shown in the Tire
Usage chart below are designed to
provide the best all around per­
formance for normal vehicle oper­
ation. When inflated
as recom­
mended on the tire pressure plac­
ard, located
on the left door of
your vehicle, they have the load
carrying capacity to operate satis­
factorily at all normal highway
speeds.

Tires should be checked regu­
larly for proper inflation pressure,
wear, and damage. The following
information will assist you in prop­
erly caring for your tires:
Inflation
Pressure-The tire in­
flation pressures listed on the tire
placard have been selected to pro­
vide the best tire life, riding com­
fort and handling stability for nor­
mal driving conditions. When in­
flated at the highest pressures
shown
on the placard, the tires
have the load carrying capacity to
operate satisfactorily at all loads
up to and including the vehicle
capacity load (total pounds)
which also
is shown on the plac­
ard.
In addition, for those owners
who prefer the utmost
in com­
fort , the reduced tire pressures
listed on the placard may be used
when loads of 4 occupants or less
are carried.

Typical Tire Placard Located On The Left Door Of Your Car
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
56 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,

Downloaded from www.Manualslib.com manuals search engine 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 applic­
able when a vehicle has been inopera­
tive 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 (after
vehicle has been driven 10 miles or at speeds of more than 60 miles per hour). Do not "bleed" or re­
duce 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, or 40 psi for 0 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 t,he 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.
When towing 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.
57
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.
The original equipment tires in­
corporate built-in tread wear
in­
dicators to assist you in determin­
ing when your tires ,have been
worn to the point of needing re­
placement. These indicators ap­
pear
as Ij2 inch wide bands when
tire tread depth
is 1/16 inch or
less. When the indicators appear
in two or more adjacent grooves,
tire replacement due to tread wear
is recommended.
To equalize wear, it
is recom­
mended that the tires be rotated
every
6,000 miles (or sooner if
