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

GENERAL INFORMATION
0-6

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:

Key of Lock

Code Number

0V11

Cutting or Tumbler

position from head

of lock
Key Cutting

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"
J

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

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.

Water Valve

Installation of the water valve is illustrated in Figure

113.
An inoperative valve must be replaced.

GENERAL DESCRIPTION

The engine tune up
is
important
to the
modern automo-

tive engine with
its
vastly improved power and perform-

ance.
The
higher compression ratios, improved electri-

cal systems
and
other advances
in
design, make today1 s

engines more sensitive
and
have
a
decided effect
on

power, performance and fuel consumption.

It
is
seldom advisable
to
attempt
a
tune up
by
correc-

tion
of one or two
items only. Time will normally
be

saved
and
more lasting results assured
if the
technician

will follow
a
definite
and
thorough procedure
of
analysis

and correction
of all
items affecting power, performance

and economy.

The tune
up
will
be
performed
in
two parts.
The
first

part will consist
of
visual and mechanical checks and
ad-

justments;
the
second part will consist
of
an instrument

checkout that
can be
performed with
any one of the
units
of service equipment available
for
this purpose. Always

follow
the
instructions provided
by the
manufacturer
of

the particular equipment
to be
used.

Additional checks
and
adjustments
are
included
in the

latter part
of
this section
for use as
required. Many
of

these operations
can be
used
to
isolate and correct trou-

ble located during
the
tune up. Where conditions
are
UB-

covered requiring major corrective action, refer
to the

appropriate section
of
this manual
or the
Passenger

Chassis Overhaul Manual
for
detailed service informa-

tion.

Typical illustrations
and
procedures
are
used except

where specific illustrations
or
procedures
are
necessary

to clarify
the
operation. Illustrations showing bench
op-

erations
are
used
for
clarification however
all
operations

can
be
performed
on the
vehicle.

MECHANICAL CHECKS
AND
ADJUSTMENTS

Spark Plug Removal

Remove any foreign matter from around spark plugs
by

blowing
out
with compressed
air,
then disconnect wires

and remove plugs.

Test Compression
(Fig. 1)

The compression check
is
important because
an
engine

with
low or
uneven compression cannot
be
tuned success-
fully.
It is
essential that improper compression
be cor-

rected before proceeding with
the
engine tune
up.

1.
Remove
air
cleaner
and
block throttle
and
choke
in

wide open position.

2.
Hook
up
starter remote control cable
and
insert

compression gauge firmly
in
spark plug port.

CAUTION: Whenever
the
engine
is
cranked
