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.

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.

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
Crankcase Capacity
4 Cylinder 4 qt.
6 Cylinder 4 qt.
8 Cylinder (283) 4 qt.
8 Cylinder (327) 4 qt.
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.

LUBRICATION 0-16
Every 12,000 miles (more frequently*, depending on
severity of service, if vehicle is used to pull trailers,
carry full loads during high ambient temperatures,
operate in mountainous terrain or operate under other
severe conditions--Remove fluid from the transmission
sump and add one and a half quarts of fresh fluid for
Camaro and Chevy II and two quarts for Chevrolet,
Chevelle, and Corvette. Operate transmission through all
ranges and check fluid level as described above.
•Except if vehicle is equipped with transmission pro-
vided in heavy duty service options. If so equipped,
drain converter and pump every 12,000 miles and add
approximately seven and a half quarts of fresh fluid
for Chevy II and nine quarts for Chevrolet and Chevelle.
TURBO HYDRA-MATIC
Lubrication. recommendations for the Turbo Hydra-
Matic are the same as outlined for the Powerglide
transmission except for fluid capacity and filter change
listed below.
After checking transmission fluid level it is important
that the dip stick be pushed all the way into the fill tube.
Every 12,000 miles — after removing fluid from the
transmission sump, approximately 7 1/2 pints of fresh
fluid will be required to return level to proper mark on
the dip stick.
Every 24,000 miles, or at every other fluid change--
the transmission sump strainer should be replaced.
FRONT WHEEL BEARINGS
It is necessary to remove the wheel and hub assembly
to lubricate the bearings. The bearing assemblies should
be cleaned before repacking with lubricant. Do not pack
the hub between the inner and outer bearing assemblies
or the hub caps, as this excessive lubrication results in
the lubricant working out into the brake drums and
linings.
Front wheels of all passenger car models are equipped
with tapered roller bearings and should be packed with a
high melting point water resistant front wheel bearing
lubricant whenever wheel and hub are removed.
CAUTION: "Long fibre" or "viscous" type
lubricant should not be used. Do not mix wheel
bearing lubricants. Be sure to thoroughly clean
bearings and hubs of all old lubricant before
repacking.
The proper adjustment of front wheel bearings is one
of the important service operations- that has a definite
bearing on safety. A car with improperly adjusted front
wheel bearings lacks steering stability, has a tendency to
wander or shimmy and may have increased tire wear.
The adjustment of these bearings is very critical. The
procedure is covered in Section 3 of this manual under
Front Wheel Bearings—Adjust,
MANUAL STEERING GEAR
Check lubricant level every 36,000 miles. If required,
add EP Chassis Lubricant.
POWER STEERING
On models equipped with power steering gear, check
fluid at operating temperature in pump reservoir. Add
GM Power Steering Fluid, or, if this is not available, use
Automatic Transmission Fluid "Type A" bearing the
mark AQ-ATF followed by a number and the suffix letter
'A'
to bring level to full mark on dip stick.
AIR CONDITIONING
After the first 6,000 miles, check all hose clamp
connections for proper tightness.
Every 6,000 miles check sight glass under the hood,
after the system has been in operation for several
minutes. Sight glass should be clear but may, during
milder weather, show traces of bubbles. Foam or dirt
indicate a leak which should be repaired immediately.
BRAKE MASTER CYLINDER
Check level every 6,000 miles and maintain 1/4" below
lowest edge of each filler opening with GM Hydraulic
Brake Fluid Supreme No. 11.
PARKING BRAKE
Every 6,000 miles, apply water resistant lube to park-
ing brake cable, cable guides and at all operating links
and levers.
CLUTCH CROSS-SHAFT
Periodic lubrication of the clutch cross shaft is not
required. At 36,000 miles or sooner, if necessary;
remove plug, install lube fitting and apply CHASSIS
LUBRICANT.
CHASSIS LUBRICATION
For chassis lubrication, consult the lubrication chart.
It shows the points to be lubricated and how often the
lubricant should be applied.
The term "chassis lubricant" as used in this manual,
describes a water resistant EP chassis grease designed
for application by commercial pressure gun equipment.
