HOOD ASSEMBLY
Hood may be removed either with or without hinges.
To shorten aligning time, hood hinge plates may be lo-
cated by scribing a mark on hood and/or body which
outlines entire plate. See Maintenance and Adjustments -
Hood Hinge for hood adjustment procedure. Hood hinge
springs may be easily and safely removed and installed.
through the use of Tool J-9559 as follows:
1.
With hood opened only far enough to allow passage of
mechanic's arm between hood and fender, insert ends
of J-9559 (through bolt removed) between coils of
spring until barrel of tool contacts outer diameter
of spring.
2.
Open hood fully while still holding spring (with tool
installed) in hand; when hood is near fully opened
position, spring may be removed as shown in Figure
28.
3.
As soon as spring is removed, insert long bolt sup-
plied with J-9559 through holes in end of tool, pass-
ing it through spring, and install nut on bolt.
Spring may be removed from J-9559 or J-9559 may be
installed in a new spring by the following method:
1.
Place a closed 6 or 8 inch "C" clamp in a vise or
fasten it to a heavy bench top (bench should be fas-
tened to floor).
2.
Hook one end of spring in clamp and the other end
in hook of a hoist as shown in Figure 29.
3.
Stretch the spring enough to allow insertion of
J-9559. Install through bolt if spring is not to be
installed on hinge at once.
HOOD CATCH AMD LOCK (Fig. 19)
Removal
1.
Remove catch assembly as follows:
a. Remove screws retaining catch assembly to radi-
ator support.
b.
Remove screws retaining catch assembly to catch
support assembly.
c* Remove screws retaining catch assembly to grille
upper bar.
2.
Before removing hood lock plate from hood, locate
position on hood by scribing around base of lock
plate. Remove screws retaining lock plate to hood
and remove lock plate from vehicle.
Installation
1.
Install both catch and lock assemblies in reverse
order of removal procedure.
2.
Align as outlined under Maintenance and Adjust-
ments - Hood Catch.
HOOD TRIM
Crown Molding
Hood crown molding is retained by clips installed on
underside of hood. Clips may be removed by carefully
pressing them off molding mounting studs with screw
driver.
When installing a new molding, force clips onto mount-
ing studs as far as possible and then clench clips with
long-nosed pliers to eliminate gap between molding and
hood, as shown in Figure 30.
Emblem
The hood emblem is retained by four nuts which are
accessible from under the hood.
COWL VENT GRILLE
The cowl vent grille replacement procedure for Chevy
U is the same as for Chevrolet and Chevelle. Refer to
Chevrolet and Chevelle Cowl Vent Grille replacement
procedure and see Figure 16.
FRONT END ASSEMBLY
The Chevy n front end body design allows for removal
of the entire front end of the vehicle without disassembly
of front suspension of sheet metal. One man may remove
and transport the front end assembly using only a floor
jack placed under the crossmember and the vehicle front
wheels. Figure 31 illustrates the assembly in process
of removal with jack stand in position under rocker panel.
Proceed with removal
as.
follows:
Removal
1.
Remove hood assembly as outlined in this section.
2.
Remove engine assembly as outlined in Section 6.
On 4 cylinder models, replace crossmember.
3.
Raise car from floor and install jack stands as
shown in Figure 31.
4.
Remove pitman arm from steering gear as outlined
in Section 9.
5.
Remove steering gear mounting bolts from skirt
assembly.
6. Remove 4 bolts securing each skirt assembly to
lower dash brace.
7.
Remove fender-to-rocker extension mounting screws
and record shimming.
8. Remove brake hydraulic line and fuel line from right
hand skirt.
9. Position floor jack or equivalent under front cross-
member.
10.
Remove hydraulic line from main cylinder.
11.
Remove fender-to-cowl mounting screws and record
shimming.
12.
Remove upper skirt-to-dash mounting screws and
record shimming.
13.
Remove front end from vehicle as shown in Figure
31.
Inspection
If car has been involved in a collision, it is advisable
to carefully inspect cowl and dash area for damage. Pay
particular attention to welds, cage nuts, weld nuts and
skirt mounting surfaces. Cage and weld nuts may be
repaired by outright replacement (the best method), or
by the installation of spiral thread inserts. If the spiral
inserts are used, follow the instructions furnished by the
manufacturer. -
Installation
%, position front end assembly at upper dash mounts
and lower dash support, align screw holes with drift
punch and install all mounting screws and bolts
loosely; do not tighten until all screws and bolts are
started. Replace original shimming.

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.

DIRECTIONAL SIGNAL
Directional signal assemblies provide as standard pro-
duction equipment a lane changing feature and hazard
warning system on all model applications. Two different
design switches are used as shown in Figure 55. Major
difference between the two units is that one type has can-
celling and detent springs which are serviceable, other-
wise both units are not repairable and must be replaced
as an assembly in service.
Due to the integral design relationship of the signal
switch and the energy absorbing steering column, refer-
ence should be made to Steering, Section 9 of this manual
whenever any service operations are performed on the
steering column. The directional signal switch replace-
ment procedures covered in this section are intended to
supplement the detail service operations outlined in Sec-
tion 9.
Special note should be taken of the fact that different
signal flasher units are used in Chevrolet models depend-
ent on the number of lamps to be operated. The hazard
warning unit, even though an integral component of the
directional switch assembly, requires the installation of
an additional flasher unit in the fuse panel capable of op-
