KEYS AND LOCKS

Four keys (two hexagonal head and two round head) are

provided with each vehicle. The hexagonal-head key

operates the ignition switch and front door locks. The
round-head key operates the locks for the glove box and

rear compartment lid.

' Lock cylinders (except trunk) are furnished for service

uncoded, this necessitates the coding of these replace-

ment lock cylinders.

NOTE: In service, the trunk and glove box

lock cylinders are provided together with the

trunk lock cylinder coded and the glove box

cylinder uncoded.

The side bar type lock (fig. 18) is used for the ignition,

front doors and trunk. The glove box lock is of the wafer

CHEVROLET CHASSIS SERVICE MANUAL

GENERAL INFORMATION

Once the code number of the lock is obtained look up

this number in a key cutting book.

All side bar locks (except trunk) furnished to the field

by the Parts' Department are uncoded, that is, they are

furnished without tumblers, springs or spring retainers,

these parts are serviced separately. The tumblers come

in five different depths, indicated by numbers.

The side bar locks have six tumbler positions, and in

looking up the cutting code, the following may be used as

an example. After key code number is determined, either

from key or from number stamped on lock cylinder refer

to your code book and record the key cutting information

as follows:

Code Numerical

545431

123456

NOTE:
Key blanks used for ignition and door

locks are stamped with an "A" while rear com-

partment and glove box blanks are stamped with

a "B".

The number that is written above the cutting or tumbler

position indicates each different tumbler which is to be

dropped into each tumbier slot of the lock.

In cases where a code book is not available, the dia-

gram shown on Figure 19 may be used to determine the

tumblers required to assemble an uncoded lock cylinder.

1.
Lay the key on the diagram (fig. 19) with bottom of

key flush with edge of the drawing, head and point

carefully lined up.

2.
Read the code in numbers 12345 from the head of the

key to the end from positions 1 to 6 inclusive. As

each depth is determined write that number in the

blank space provided above the position numbers

(1-2-3-4-5-6).

3.
With key properly lined up on diagram, all cuts that

show in the first section are marked
"1"

4.
Cuts that fall in the first black section, mark "2".

5. Cuts that fall in the first white section, mark "3".

6. Cuts that fall in second black section, mark "4".

7. Cuts that fall in the second white section, mark "5".

After the numbers have been determined and written

above the cutting positions the lock cylinder should be

assembled as follows.

Lock Cylinder Assembly—Refer to Figure 20

1.
Hold cylinder with head of cylinder away and starting

•... at the head of the cylinder, insert the tumblers in
their proper slots in the order called for by the

code, ribbed side toward you and long point down.

2.
After all tumblers are in place, check for correct-

ness with the code. Then press tumblers down with

one finger.

3.
Insert one tumbler spring in the space provided

above each tumbler.

CAUTION: If the springs are tangled, do not

pull them apart—unscrew them.

4.
Reverse the lock cylinder so that the head of the

cylinder is now toward you. Insert the spring re-

tainer so that one of its six prongs enters into each

of the springs and the two large end prongs slide into

the slots at either end of the cylinder. Press the

retainer down with one finger.

5. To check, insert proper key and if tumblers are in-

stalled properly the side bar will be allowed to drop

down. If bar does not drop down, remove the key,

spring retainer, springs and tumblers and reas-

semble correctly.

NOTE:
If the tumblers have not been assembled

correctly and not according to the code, the

tumblers can be removed from the cylinder by

holding it with the tumbler slots down, pulling

the side bar out with the fingers and jarring the

cylinder to shake the tumblers out. This pro-

cedure is necessary because after the tumblers

have been pressed down into the cylinder they

are held in their slots by the cross bar.

6. If after checking it is found that the lock is as-

sembled properly, remove key and place cylinder in

GENERAL DESCRIPTION

CHEVROLET, CHEVELLE,
AND
CAMARO

Components
of the
Chevrolet, Chevelle,
and
Camero

heaters
are
attached
to the
firewall
on the
right side
of

the vehicle. The blower
and air
inlet assembly and water

hoses
are
located on the engine side
of
the firewall while

the heater core and distributor duct
are on the
passenger

side.

The heater operates
on
outside
air
only with
the

blower receiving
its
airflow from
the
cowl vent plenum

chamber.

Since
the
unit
has no
water valve, water circulation

keeps
the
core
hot at all
times.
Air
passing through
the

core receives maximum heat from
the
core.

In operation, three levers control
all
heater opera-

tions.
The
AIR-FAN lever
is a
combination control;

moving
the
lever half-way opens
the
AIR door
(by
means

of
a
bowden cable)
to
supply outside
air to the
three

speed blower. Further movement
of the
lever operates

the blower.
The
other levers depend on bowden cables
to

operate
the
diverter doors located
in the
distributor

duct
to
control heater output and operation.

At
the
heart
of
the heater operation
is the
temperature
door.
Air
from
the
blower follows parallel paths through

the distributor duct, with
one
path passing through
the

heater core
and the
other path bypassing
the
core.
The

temperature door, operated
by the
TEMPERATURE
con-

trol lever,
is
placed
in the
duct
so
that when
it
closes
off

the path from
the
heater core,
it
allows ambient airflow

through
the
unheated path.
In the
opposite position only

heated airflow
is
allowed. Final heater output tempera-

ture
is
dependent upon
the
proportion
of
heated
and

unheated
air
blended together according
to the
setting
of

this temperature door.
To
insure positive closing
of
this

door when
the
heat lever
is in the off
position,
a cam

lock device
is
utilized
in the
control linkage
of the

Chevelle heater only.

Just beyond
the
temperature damper door
is the Air

door, operated
by the
AIR-FAN control lever, which
is

the
air
on-or-off control. This door will
be
open when-

ever
the
heater blower
is in
operation.

The defroster door, operated
by the
DEFROSTER

lever, acts
to
divert
the
heated
air
flow
up
through
the

defroster ducts
for
de-fogging, defrosting
or
de-icing

operations.

CORE

Fig. 2-Heater Schematic (Chevy 11)

CHEVY

Heater components are located under the instrument

panel in the passenger compartment. Hot water hoses

from the engine are routed to the fire wall to the heater

core pipes. The blower motor receives outside air from

the cowl vent plenum chamber through the adapter as-

sembly. The air enters the heater core chamber where

it either bypasses or passes through the core depending

on the position of the temperature door, controlled by

the TEMPERATURE lever on the instrument panel.

Temperature control is achieved by adjusting the position

of this door to vary the proportion of heated and unheated

air introduced to the car interior. As the air flow is

drawn out of the heater core chamber (in the desired

proportion of hot and cold), it enters the blower where

it is thoroughly mixed, assuring a uniform temperature.

The distributor guides the air flow through either the

floor outlet or the defroster outlets depending on the

setting of the DEFROSTER lever on the instrument

panel. The AIR-FAN lever is the air OFF control as

well as the blower control.

CONTROLS

Control Assembly (Chevrolet, Chevelle, Camaro,

and Chevy II)

Air-Fan Lever

Since the heater makes use of outside air only, this

lever serves as an "air on or off" control by actuating

a damper in the distributor assembly downstream ("up-

stream" in the Chevy n heater) from the blower assem-

bly. With the lever in the half-way position, this damper

will be open to allow airflow into the vehicle. Moving the

lever further will actuate the three-speed (LOW-MED-

HIGH) fan lever which controls the blower motor and

determines the volume and force of the air flowing

through the heater core into the car.

Temperature Lever

Through its bowden cable, this lever controls the
positioning of the temperature door in the distributor

duct. This door allows airflow through either the heater

core (full RIGHT) or the bypass duct around the heater

core (full LEFT). Because the water temperature is con-

stant, this knob acts as an air mixture control, control-

ling temperature by varying the proportions of heated

and unheated air blended in the heater distributor duct.

The cam lock device at the damper door operating

lever (Chevelle only) may be adjusted as follows: Loosen

the two attaching screws. Place the cam in the closed

position and insert a pin through holes provided, locking

the cam in this position. Rotate the entire assembly

toward the closed position. Hold closed with some force

and tighten attaching screws. Remove the locking pin.

Defrost Lever

The defrost lever controls the position of the damper

(or deflector) door located in the heater and defroster

assembly. In the "off" position full airflow will go to

the floor duct for car heating purposes. In the "de-ice"

position the diverter door will drop down and divert

almost all the airflow to the defroster duct. (This posi-

tion will seldom be needed except for extreme de-icing

requirements). A "detent" position is built into the

Fig. 3—Heater Control Panel (Chevrolet Shown as Typical)

CHEVROLET CHASSIS SERVICE MANUAL

HEATER AND AIR CONDITIONING 1A-3

linkage of this lever which will provide partial airflow

only to the defroster duct and which should be used for,

all normal defogging operations.

CORVETTE

Heater components are attached to the dash panel on

the right side of the vehicle with the air inlet assembly

on the engine side and the heater and air distributor

assemblies beneath the instrument panel within the pas-

senger compartment.

The heater operates on outside air only with the blower

receiving its air flow from the cowl vent plenum

chamber.

No water valve is utilized in the system. Therefore,

water flows through the heater core constantly while

the engine is running, keeping the core at maximum

temperature at all times.

Airflow through the system is shown in Figure 1.

Controls

Two knobs control all heater operations:

The FAN-TEMP knob is rotated to turn the blower

on and off and control blower speed and is pulled out

as desired to regulate heater temperature.

The AIR-DEF knob is the air on-and-off control as

well as the defroster control.

Temperature Damper: Door

At the heart of the heater operation is the temperature

damper door. Air from the blower follows parallel paths

through the distributor duct, with one path passing

through the heater core and the other path bypassing the

core.

The temperature damper door is placed in the duct

so that, when closed, the path of the heated air leaving

the heater core is blocked while the ambient air path

remains open. Positive closing of this door when no

heat is being called for is assured by a cam assembly

at the door operating lever. As the FAN-TEMP knob

is pulled out, the damper door is opened accordingly,

allowing varying proportions of heated air to mix with

the unheated airflow, thus providing heater outlet tem-

perature control. With the knob pulled fully out the
Fig.
4—Heater Controls (Corvette)

ambient air path is blocked and all airflow passes

through the heater core. Final heater output temperature

is dependent upon the proportion of heated and ambient

air blended together according* to the setting of the

temperature damper door.

Air and Defrost Damper Doors

Beyond the temperature damper door are the air door

and the defroster door, both operated through a single

bowden cable by the AIR-DEF knob. The first half of the

travel of this knob opens the AIR door allowing the

airflow to pass into the interior of the car through the

floor distributor openings. Pulling the AIR-DEF knob

fully out causes the defroster door to open, diverting

this airflow to the defroster ducts for defogging, de-

frosting or deicing operations.

NOTE: Since this knob is the air on-or-off

control, it should be pulled at least halfway out

before turning on the blower.

Fan Control

Rotate the FAN-TEMP knob to operate the three-

speed blower, increasing the velocity of the air through

the heater. The fully counter-clockwise position of the

knob is the off position. Turn clockwise to the desired

blower speed; fully clockwise for high blower speed.

HEATER AND AIR CONDITIONING 1A-21

"De-Fog"
Position

In the event that the front windshield should require

removal of a fogging condition, the owner at his option

may direct air to the windshield. The "De-Fog" position

directs part of the air to the windshield while retaining a

certain amount through the floor outlets. The temper-

ature of the air remains the same as it was prior to the

control being placed in the "De-Fog" position. Five

blower speeds are available. The temperature of the air

and the blower speed are selected by the automatic

controls and are dependent upon the in-car temperature.

"De-Ice" Position

The "De-Ice" position provides full heat with "Hi"

blower directing the entire airflow to the windshield to

melt ice. The automatic controls are completely defeated

and as a result, full heat with "Hi" blower are the only

conditions that can be received. The system will turn on

immediately in this position even though the engine

coolant might be cold.

General Information

Three start up conditions can be achieved with

Comfortron.

Weather

Cold
Method of Starting System

System starts as soon as engine coolant is

hot.

Hot System starts immediately when AC is

required.

Any System starts immediately in "De-Ice"

position.

UNIVERSAL SYSTEM

A self-contained unit, the dealer installed Universal

System operates on recirculated air only and entirely

independent of the vehicle heater. Recirculated inside air

is drawn into the unit, passed through the evaporator core

and into the car through the adjustable outlets in the

evaporator case. The entire unit mounts compactly

beneath the dash. Temperature control is by means of a

thermostatic switch.

The compressor used with the Universal System is

identical to that used for the Four-Season system except

for displacement. Underhood components are similar in

placement to the Four-Season system.

Controls

Universal system controls are the AIR knob controlling

the three speed blower motor switch and the TEMP knob

which controls the setting of the thermostatic switchi

Switch adjustment is covered elsewhere in this section.

When operating this system the Heater must be fully off.

CHEVY II ALL-WEATHER SYSTEM

The Chevy n All-Weather Air Conditioning System,

Figure 33, operates in conjunction with the heater to

provide a complete air conditioning system operating on

either outside air, recirculated air or a combination of

both. The cooling unit attaches to the heater distributor

and utilizes the heater blower. Several controls allow
full use of either the heating or cooling features of the

system. During marginal weather, it is possible to pro-

vide heated air at floor level and cooled air at breath

level.

A schematic view of the air conditioning underdash

components is provided in Figure 34 to aid in under-

standing airflow and control operation.

The evaporator assembly, located in the passenger

compartment attached directly to the heater distributor,

contains the evaporator core, expansion valve, thermo-

static switch and the air conditioning "ON" knob. The

thermostatic switch, utilized as the cooling control, feels

the temperature of the cooled air leaving the evaporator

core and turns the compressor on and off in accordance

with cooling needs. Refrigerant lines connect the evap-

orator assembly to the other system components located

in the engine compartment.

The six cylinder air conditioning compressor, com-

pletely field serviceable, is bracket-mounted to the

engine and is belt driven from the crankshaft pulley. A

muffler assembly, designed to eliminate compressor

pulsations is an integral part of the compressor con-

nector block. The condenser is mounted on the radiator

support just ahead of the engine radiator. The receiver-

dehydrator, with its sight glass, is located on the right

fender skirt.

Controls

Control of the air conditioning system is achieved

through the use of the heater control on the instrument

panel as well as the two knobs located on the air condi-

tioning unit itself (fig. 35).

Air Conditioning "ON" Knob

Labeled "Pull for Air Cond.", this knob diverts air-

flow from the floor distributor and through the air condi-

tioning unit. Initial movement of this knob also actuates a

switch, located at the damper door, which energizes the

compressor clutch thus putting the system into operation

and under the control of the thermostatic switch.

Temp-Cool Knob

This knob controls the thermostatic switch. Turn the

knob clockwise for more cooling, counter-clockwise for

less cooling.

Air Lever

This lever actuates the damper within the assembly

which chooses between recirculated air or outside air.
