PUSHING, TOWING AND LIFTING
Pushing
NOTE:
Towing car to start is not recommended
due to the possibility of the disabled car ac-
celerating into tow car.
AUTOMATIC TRANSMISSION
Do not attempt to start the engine by pushing the car.
Should the battery become discharged, it will be neces-
sary to use an auxiliary battery with jumper cables to
start the engine.
CAUTION: To prevent damage to electrical
system, never connect booster batteries in ex-
cess of 12 volts and connect positive to positive
and negative to negative.
Manual Transmission
When a push start is necessary turn off all electrical
loads such as heater, radio, and if possible, lights, turn
on the key, depress the clutch, and place the shift lever
in high gear. Release the clutch when your speed reaches
10 to 15 miles per hour.
TOWING
The car may be towed safely on its rear wheels with
the (selector lever in "N" (Neutral) position at speeds
of 35 miles per hour or less under most conditions.
However, the drive shaft must be disconnected or the
car towed on its front wheels if 1) Tow speeds in excess
of 35 MPH are necessary, 2) Car must be towed for ex-
tended distances (over 50 miles) or, 3) Transmission is
not operating properly. If car is towed on its front
wheels, the steering wheel should be secured to maintain
a straight ahead position.

TOWING THE CAMARO
The recommended method for towing the Camaro is
follows.
Front
Connect standard chain hooks near the outer ends of
the front suspension lower control arms in between the
coil springs and the stabilizer bar link bolt (fig. 23).
The chains should be attached to the lower lifting sling
bar so that when the vehicle is raised the rubber straps
protect the front valance panel (fig. 24). Caution should
be exercised when attaching the lower lifting bar that the
upper lifting bar does not damage the hood header panel.

Connect standard chain hooks around the axle tube from
the underneath side between the axle rear spring pad and
the brake flange plate (fig. 25). It is mandatory that the
chain hook be positioned as stated above so that the brake
lines are not damaged.
The lower lifting bar should be positioned in below the
vehicle so that the rubber straps protect the rear valance
panel. With the lower bar in this position, it is necessary
that the bar be spaced down a minimum of
1
5/8" to pre-
vent damage to the fuel tank. This can be accomplished
by placing 6.0" section of 2x4' wood blocks below the
rear section of each rear spring (fig. 26).
To facilitate towing without a helper it will be neces-
sary to attach the
2x4*
s to the rear spring by a strap or
tape.
See Figure 27.
Also it will be necessary to lock the steering wheel in
the straight ahead position prior to actually moving the
vehicle.

The shaded areas on both the front and the rear
bumpers, as shown in Figures 21, 22, 28, 29 are recom-
mended auto jack lifting points. The jack load rest must
locate under the bumper at these points. Be sure the
load rest is positioned properly on the jack before raising
the vehicle. On Corvettes, position jack on shaded areas
indicated on Figure 30. Be sure jack load rest properly
contacts frame before raising vehicle.
Lifting Car With Drive-on Hoist
Many dealer service facilities and service stations are
now equipped with a type of automotive hoist which must
bear upon some part of the frame in order to lift the
vehicle. In Figures 21, 22, 28, 29, 30 the shaded areas
indicate areas recommended for hoist contact.
LIFTING THE CORVETTE
Shaded, areas in Figure 30 indicate 'recommended
points for hoist or jack contact. When using a single post
hoist place hoist on frame side rail behind kickup at front
and forward of #3 body mount at rear. When using a
twin-post hoist, two methods are recommended.
a. If no rear axle or suspension work is contem-
plated, use either suspension adapters or drive-
on adapters at the front, and drive-on adapters
at the rear. If a need for axle work develops, use
jack stands beneath the frame side rails on each
side and lower rear post.
b.
If rear axle work is contemplated, use either
suspension adapters or drive-on adapters at the
front and frame lift adapters as shown in Figure
31.
If frame lift adapters are not available, use
jack stands.
NOTE:
Wooden blocks, bolted to steel beam
shown in Figure 31 are necessary to allow
beam to clear exhaust system.

The selection of the proper lubricant and its correct
application at regular intervals does much to increase the
life and operation of all moving parts of the vehicle.
Consequently, it is important that the correct grade of
oil or grease, as noted in the following pages, be used.
ENGINE CRANKCASE OIL

8 Cylinder (350) 4 qt.
8 Cylinder (396) 4 qt.
8 Cylinder (427) Chevrolet 4 qt.
8 Cylinder (427) Corvette 5 qt.
For 4 Cyl. Add .5 qt. with filter change;
1 qt. for 6 and 8 Cyl. engines.
Lubrication
Crankcase oil should be selected to give the best per-
formance under the climatic and driving conditions in the
territory in which the vehicle is driven.
During warm or hot weather, an oil which will provide
adequate lubrication under high operating temperatures
is required.
During the colder months of the year* an oil which will
permit easy starting at the lowest atmospheric tempera-
ture likely to be encountered, should be used.
When the crankcase is drained and refilled, the crank-
case oil should be selected, not on the basis of the exist-
ing temperature at the time of the change, but on the
lowest temperature anticipated for the period during
which the oil is to be used.
Unless the crankcase oil is selected on the basis of
viscosity or fluidity of the anticipated temperature, dif-
ficulty in starting will be experienced at each sudden
drop in temperature.
SAE Viscosity Oils
SAE Viscosity Numbers indicate only the viscosity or
body of the oil, that is, whether an oil is a light or a
heavy body oil, and do not consider or include other
properties or quality factors.
The lower SAE Viscosity Numbers, such as SAE 5W
and SAE 10W which represent the light body oils, are
recommended for use during cold weather to provide
easy starting and instant lubrication. The higher SAE
Viscosity Numbers such as SAE 20 and SAE 20W, which
represents heavier body oils, are recommended for use
during warm or hot weather to provide improved oil
economy and adequate lubrication under high operating
temperatures.
Oils are available which are designed to combine the
easy starting characteristics of the lower SAE Viscosity
Number with the warm weather operating characteristics
of the higher SAE Viscosity Number. These are termed
"multi-viscosity oils," SAE 5-10W, SAE 5W-20, SAE
10W-20W, and SAE 10W-30.
The following chart will serve as a guide for the
selection of the correct SAE Viscosity Number for use
under different atmospheric temperature ranges, and
suggests the appropriate SAE Viscosity Numbers when
multi-viscosity oils are used.

SAE 5W-30 oils may be used during periods when
temperatures of 32° and below are to be expected.
Types of Oils
In service, crankcase oils may form sludge and varnish
and under some conditions, corrosive acids unless pro-
tected against oxidation.
To minimize the formation of these harmful products
and to assure the use of oil best suited for present day
operating conditions, automobile manufacturers have de-
veloped a series of sequence tests designed to evaluate
the ability of any oil to properly lubricate automobile
engines.
It is recommended that only those oils which are
certified by their suppliers as meeting or exceeding the
maximum severity requirements of these sequence tests
(or GM Standard 4745-M) be used in Chevrolet engines.
Certified sequence tested oils will be described as such
on their containers.
Maintaining Oil Level
The oil gauge rod is marked "Full" and "Add Oil."
These notations have broad arrows pointing to the level
lines.
The oil level should be maintained between the
two lines, neither going above the "Full" line nor under
the "Add Oil" line. DO NOT OVERFILL. After operating
vehicle allow a few minutes for oil to return to crankcase
before checking oil level.
Check the oil level frequently and add oil when
necessary.
Oil and Filter Change Intervals
NOTE:
Under prolonged dusty driving condi-
tions,
it is recommended that these operations
be performed more often.
OIL
To insure continuation of best performance, low main-
tenance cost and long engine life, it is necessary to
change the crankcase oil whenever it becomes contami-
nated with harmful foreign materials. Under normal
driving conditions draining the crankcase and refilling
with fresh oil every 60 days or every 6000 miles which-
ever occurs first, is recommended.
It is always advisable to drain the crankcase only after
the engine has become thoroughly warmed up or reached
normal operating temperature. The benefit of draining is,
to a large extent, lost if the crankcase is drained when
the engine is cold, as some of the suspended foreign
material will cling to the sides of the oil pan and will not
drain out readily with the cold, slower moving oil.
OIL FILTER
Change engine oil filter every 6000 miles or every 6
months, whichever occurs first.
NOTE:
For Vehicles in heavy duty operation
involving continuous start-stop or prolonged idl-
ing, engine oil should be changed after 2500-
3000 miles of operation. The filter should be
changed after 5000-6000 miles of operation.
Crankcase Dilution
Probably the most serious phase of engine oil deterio-
ration is that of crankcase dilution which is the thinning
of the oil by fuel vapor leaking by pistons and rings and
mixing with the oil and by condensation of water on the
cylinder walls and crankcase.
Leakage of fuel, or fuel vapors, into the oil pan occurs
mostly during the "warming up" period when the fuel is
not thoroughly vaporized and burned. Water vapor enters
the crankcase through normal engine ventilation and
through exhaust gas blow-by. When the engine is not
completely warmed up, these vapors condense, combine
with the condensed fuel and exhaust gases and form acid
compounds in the crankcase.
As long as the gases and internal walls of the crank-
case are hot enough to keep water vapor from con-
densing, no harm will result. However, when the engine
is run in low temperatures moisture will collect and
unite with the gases formed by combustion resulting in
an acid formation. The acid thus formed is likely to
cause serious etching or pitting which will manifest itself
in excessively rapid wear on piston pins, camshaft
bearings and other moving parts of the engine, oftentimes
causing the owner to blame the car manufacturer or the
lubricating oil when in reality the trouble may be traced
back to the character of fuel used, or a condition of the
engine such as excessive blowby or improper carburetor
adjustment.
Automatic Control Devices to Minimize
Crankcase Dilution
All engines are equipped with automatic devices which
aid greatly in minimizing the danger of crankcase
dUution.
The thermostat, mounted in the cylinder head water
outlet, restricts the flow of water to the radiator until a
predetermined temperature is reached, thus minimizing
the length of time required to reach efficient operating
temperature, reducing the time that engine temperatures
are conducive to vapor condensation.
A water by-pass is included in the cooling system,
utilizing a hole in the front of, the cylinder block. This
allows a limited circulation of coolant, bypassing the
thermostat until thermostat opening temperatures are
reached. This system provides a uniform coolant tem-
perature throughout the engine, eliminating localized
hot-spots, improving exhaust valve life, provides fast
warmrup of lubricating oil and fast temperature rise in
the coolant which provides fast heater operation in cold
weather.
A thermostatic heat control on the exhaust manifold
during the warming up period, automatically directs the
hot exhaust gases against the center of the intake mani-
fold, greatly aids in proper vaporization of the fuel.
An automatic choke reduces the danger of raw or
unvaporized fuel entering the combustion chamber and
leaking into the oil reservoir.
An.
efficient crankcase ventilating system drives off
fuel vapors and aids in the evaporation of the raw fuel
and water which may find its way into the oil pan.
