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.

PRECAUTIONS IN HANDLING REFRIGERANT LINES
• All metal tubing lines should be free of kinks, be-
cause of the restriction that kinks will offer to the
flow of refrigerant. The refrigeration capacity of the
entire system can be greatly reduced by a single
kink.
• The flexible hose lines should never be bent to a
radius of less than 10 times the diameter of the hose.
• The flexible hose lines should never be allowed to
come within a distance of 2-1/2" of the exhaust
manifold.
• Flexible hose lines should be inspected at least once
a year for leaks or brittleness. If found brittle or
leaking they should be replaced with new lines.
• Use only sealed lines from parts stock.
• When disconnecting any fitting in the refrigeration
system, the system must first be discharged of all
refrigerant. However, proceed very cautiously re-
gardless of gauge readings. Open very slowly, keep-
ing face and hands away so that no injury can occur
if there happens to be liquid refrigerant in the line.
If pressure is noticed when fitting is loosened, allow
it to bleed off very slowly.
CAUTION: Always wear safety goggles when
opening refrigerant lines.
• In the event any line is opened to atmosphere, it
should be immediately capped to prevent entrance
of moisture and dirt.
• The use of the proper wrenches when making con-
nections on "O" ring fittings is important. The use
of improper wrenches may damage the connection.
The opposing fitting should always be backed up with
a wrench to prevent distortion of connecting lines or
components. When connecting the flexible hose con-
nections it is important that the swagged fitting and
the flare nut, as well as the coupling to which it is
attached, be held at the same time using three dif-
ferent wrenches to prevent turning the fitting and
damaging the ground seat.
• "O" rings and seats must be in perfect condition.
The slightest burr or piece of dirt may cause a leak.
• Sealing beads on hose clamp connections must be
free of nicks and scratches to assure a perfect seal.
MAINTAINING CHEMICAL STABILITY IN THE
REFRIGERATION SYSTEM
The metal internal parts of the Chevrolet refrigeration
system and the refrigerant and oil contained in the sys-
tem are designed to remain in a state of chemical
stability as long as pure R-12 and uncontaminated re-
frigeration oil is used in the system.
However, when abnormal amounts of foreign materials,
such as dirt, air or moisture are allowed to enter the
system, the chemical stability may be upset. When ac-
celerated by heat, these contaminates may form acids
Fig.
40-^-System Contaminants
and sludge and eventually cause the breakdown of com-
ponents within, the system. In addition, contaminates may
affect the temperature-pressure relationship of R-12,
resulting in improper operating temperature and pres-
sures and decreased efficiency of the system.
The following general practices should be observed to
insure chemical stability in the system.
• Whenever it becomes necessary to disconnect a
refrigerant or gauge line, it should be immediately
capped. Capping the tubing will also prevent dirt and
foreign matter from entering.
• Tools should be kept clean and dry. This also in-
cludes the gauge set and replacement parts.
• When adding oil, the container should be exception-
ally clean and dry due to the fact that the refrigera-
tion oil in the container is as moisture-free as it is
possible to make it. Therefore, it will quickly absorb
any moisture with which it comes in contact. For
. this same reason the oil container should not be
opened until ready for use and then it should be
capped immediately after use.
• When it is necessary to open a system, have every-
thing you will need ready and handy so that as little

if
the operation
is
satisfactory remove the gauge

EXPANSION VALVE
A malfunction
of the
expansion valve will
be
caused
by
one of the
following conditions: valve stuck open,
valve stuck closed, broken power element,
a
restricted
screen
or an
improperly located
or
installed power
element bulb.
The
first three conditions require valve
replacement.
The
last two may be corrected by replacing
the valve inlet screen
and by
properly installing
the
power element bulb.
Attachment
of the
expansion valve bulb
to the
evap-
orator outlet line
is
very critical.
The
bulb must be
attached tightly
to the
line
and
must make good contact
with
the
line along
the
entire length
of
the bulb. A loose
bulb will result
in
high
low
side pressures and poor
cooling.
On
bulbs located outside
the
evaporator case
insulation must be properly installed.

1.
Remove the drive belt. Cut belt off if necessary.
2.
Visually inspect the condenser, receiver-dehydrator,
compressor, mounting brackets, conditioning unit, all
connecting lines, and all controls to determine the
extent and nature of the damage.
a. No repairs, such as soldering, welding or braz-
ing, should be attempted on the condenser be-
cause of its construction. If the vapor passages
in the horizontal tubes or return bends or mani-
folds have been damaged in any way, the con-
denser should be replaced with a new one.
b.
The receiver-dehydrator should be replaced if
there is any evidence of its having sustained
either internal damage or a fracture at any of
the lines or welded joints or if the system has
been exposed to the atmosphere for an undeter-
mined period of time.
c. Examine the compressor for any visible external
damage.
d. The evaporator should be examined for damage
and, if necessary, removed or replaced or the
entire unit processed where damaged or exposed
to the atmosphere.
e. All connecting lines and flexible hoses should be
examined throughout their entire length for dam-
age.
If damaged in any manner, replace with new
lines.
f. Check all controls and connecting wires for
damage and replace with new parts where needed.
g. Check the clutch pulley for proper operation and
freedom from damage.
3.
Install gauge set.
4.
Purge the system. Pressure should not exceed 3 to
5 pounds.
5. Remove the compressor from mounting and remove
the oil test fitting.
6. Pour out the oil into a clean glass container and ex-
amine it for any foreign substance such as dirt,
water, metal particles, etc. If any of these are
present, the compressor and receiver-dehydrator
should be replaced and the other system components
should be flushed with liquid refrigerant.
7. If the oil is clean and free of any harmful substance,
replace oil with Frigidaire Oil available through
Parts Stock.
NOTE:
If the system components have been
replaced or flushed, replace the full charge of
oil. If not, add no more fresh oil than was
drained in Step 6.
8. Charge up the compressor to drum or can pressure
and leak test the compressor seals prior to in-
stallation of compressor.
9. Reinstall the compressor and evacuate the system
by following the Evacuating Procedure.

FUSES
A fuse, located in the junction block protects the entire
air conditioning system except for the blower when op-
erating at high speed.
A second fuse, to protect the high speed blower circuit,
is located in the electrical wiring between the horn relay
and the Air Conditioner relay (except Universal). The
Universal unit has a fuse in the line between the ignition
switch and the Air Conditioner blower switch. See the
specification page for the proper replacement fuse.
FOUR SEASON HEATER COMPONENTS
Corvette
The heater components of the system are, in general,
much the same as those of the standard Corvette heater.
Heater hoses carry the engine coolant to the heater core,
located in the air distributor duct beneath the instrument
panel.
A significant difference is that in the Corvette Air
Conditioning System there is no flow through the heater
core until the COOL IN-HOT PULL knob is pulled out.
This movement opens the vacuum switch on the air
distributor assembly and allows vacuum to be applied
to the water valve mounted in the engine compartment,
opening the valve. Thus the heater core is unheated
until needed, at which time it receives full flow of the
engine coolant. Air passing through the core receives
maximum heat which is tempered by mixing with un-
heated air before entering the passenger compartment.
Heater Core
Replacement
The heater core in the Corvette Air Conditioning
System is removed in the same manner as the core in
the Corvette heater. The distributor assembly must first
be removed from under the dash as covered previously
in this section before the core can be removed and
replaced.
