GENERAL DESCRIPTION

The Chevelle instrument cluster assembly consists
of:

a speedometer;
a
fuel gauge;
a
generator,
an
engine
tem-

perature and an
oil
pressure indicator lamp, and includes

a clock
on
deluxe models.
On
super sport models,
am-

meter, coolant temperature
and oil
pressure gauges
re-

place
the
appropriate indicator lights. Except
for the

speedometer,
all of the
indicator lamps, instruments
and

gauges
of
these clusters may
be
serviced without remov-

ing
the
instrument cluster assembly from
the
vehicle.

In addition
to the
instrument indicator lamps,
a
brake

warning lamp
is
included
in the
cluster
as
standard

equipment.
The
indicator
is
connected
to the
parking
brake
and
brake pressure differential switches
and

serves
a
dual function.
It
lights when the parking brake

is applied
and
also when
the
brake pedal
is
applied,
if a

malfunction should occur
in the
brake system
due to a

loss
of
hydraulic pressure. Servicing
of the
hydraulic

pressure differential switch
is
covered
in
Section
5 of

this manual.

Regular maintenance
is not
required on the instrument

cjLuster
or its
components other than maintaining dean

and tight electrical connections, replacing defective parts

and keeping
the
speedometer cable properly lubricated.

GENERAL DESCRIPTION

The standard Camaro instrument cluster assembly con-

sists
of two
circular units which house
the
speedometer

and fuel gauge assemblies.
The oil
pressure, left-hand

directional
and
brake warning indicators
are
located
in

the face
of the
speedometer bezel while generator,
tem-

perature
and
right-hand directional indicators are grouped

with
the
fuel gauge unit.
The
high beam indicator
is

located between
the
cluster bezels.

A special instrumentation package
is
available with
the

eight-cylinder engine
and
center floor console combina-

tion.
The
special cluster includes:
a
clock; coolant

temperature,
oil
pressure, fuel
and
ammeter gauges,

mounted forward
on the
seat separator console;
a ta-

chometer
in the
right circular housing
of the
dash
in-

strument cluster; and
a low
fuel level indicator replacing

the
oil
pressure indicator lamp
in the
instrument cluster.

The instruments
and
gauges,
may be
serviced only

after
the
instrument cluster
is
removed from
the
vehicle.

Indicator
and
cluster lamps except
for the
high beam

indicator
may be
replaced without removing
the
cluster

assembly. Partial cluster removal
is
necessary when

replacing
the
high beam indicator due
to its
proximity
to
the upper brace
rod
anchor plate.
The
bulbs
are in-

stalled
in
plastic sockets which lock into
the
cluster

housing and make contact with
the
printed circuit.

A
low
level fuel warning system
is a
special feature

available with
the
floor console gauge pack. This
sys-

tem includes
an
indicator lamp
in the
dash cluster and
a

semi-conductor unit senses
the
change
in
electrical
re-

sistance
of the
fuel system circuitry
as
variations
in

fuel level occur.
The
sensing device
is
replaced
as a

unit
if
found defective.

The brake warning light serves
a
dual purpose.
It

functions
as an
indicator when
the
parking brake
is ap-

plied
and
also
if
there
is a
malfunction (loss
of
hydraulic

pressure)
in the
brake system. Switches which provide

the signal
to
operate
the
light
are
located
at the
parking

brake assembly
and at the
brake master cylinder
in the

hydraulic lines. Service
of the
brake pressure differ-

ential switch unit
is
covered
in
Section
5 of
this manual.

Regular maintenance
is not
required on
the
instrument

cluster
or its
components other than maintaining clean,

tight electrical connections, replacing defective parts

and keeping
the
speedometer properly lubricated.
