UNIT AND SERIAL NUMBER LOCATIONS
For the convenience of servicemen when writing up
certain business papers, such as L. & M.R.'s Product
Information Reports, or reporting product failures in
any way, we are showing below the location of various
unit numbers. These unit numbers and their prefixes
and suffixes are necessary on these papers for various
reasons—such as accounting, follow-up on production,
etc.

The prefixes on certain units identify the plant in which
the unit was manufactured, and thereby permits proper
follow-up of the plant involved to get corrections made
when necessary.
Engine Unit Number
The engine unit number (figs. 3 and 4) shows manu-
facturing plant, month and day of manufacture, and
transmission type. A typical engine number would be
F1210FA, which would breakdown thus:
F~Manufacturing Plant (F—Flint, T—Tonawanda)
12—Month of manufacture (December)
10—Day of manufacture (tenth)
FA—Transmission and engine type
Vehicle Serial Number
A typical vehicle serial number tag (fig. 1) yields
manufacturers identity, vehicle type, model year, as-
sembly plant and production unit number when broken

GENERAL DESCRIPTION
WHEELS
Chevrolet, Chevelle, Camaro, Chevy n, and Corvette
are base equipped with welded steel wheels. Five studs
with nuts fasten each wheel to the front hub or rear axle
flange. Disc brake equipped vehicles (except Chevrolet
and Corvette) require special 14 inch diameter wheels
with a revised design for clearance, Chevrolet disc brake
equipped vehicles have 15 in. diameter wheels as do all
Corvettes.
Chevrolet station wagons, Chevelle Super Sport 396,
Corvette and Camaro Super Sport 350 are base equipped
with 6 in. width wheels. All other vehicles have 5 in.
width wheels, except Chevy n 100, 300 and 500 Series
Sedans, which have 4 in. width wheels.
Do not install 6 inch width wheels or snow chains on
Chevrolets equipped with rear fender skirts.
TIRES
The factory installed tires on Chevrolet passenger
cars are selected to provide the best all around tire
performance for all normal operation. They are de-
signed to operate satisfactorily with loads up to and in-
cluding the specified full rated load capacity of the
automobile when inflated as recommended in the Vehicle
Capacity Rating and Recommended Tire Inflation Pres-
sures Table (see Specifications).
Optional Oversize and 8-Ply Rating Tires
{Chevrolet and Chevelle Only)
Oversize or 8-ply rating tires are not necessary on
passenger cars for normal requirements. However, an
extra margin of tire service is available when these
options are used at loads up to and including full rated
load.
Optional oversize 4-ply rating and/or 8-ply rating
tires are available on models as indicated in the Tire
Usage Chart (see Specifications). On some models (ex-
ample—Station Wagon), space limitations do not permit
the use of a larger size tire; hence, the 8-ply rating
tire is an available option.
In either case, these tires are applicable to extended
operation at or near full rated load or for trailer towing
when an extra margin of tire service is desired. How-
ever, use of a larger tire or an 8-ply rating tire should
not be construed as permitting an increase in the full
rated vehicle load (see Specifications).
MAINTENANCE AND ADJUSTMENTS
TIRES
Inflation Pressures
To ensure the proper tire inflation pressure for the
owners particular requirements follow the recommenda-
tions in the Vehicle Capacity Rating and Recommended
Tire Inflation Pressures Table (seeSpecifications). Keep
tires properly inflated, and check inflation pressures
periodically. This will ensure the best tire life and riding
comfort, over the full range of driving conditions.
Inspection
Every few thousand miles and at each lubrication, tires
should be checked for sharp objects or stones in the
tread. H tire is punctured, it should be repaired using
one of several repair kits available through tire manu-
facturers1 outlets.
Wear
Misalignment
This is wear due to excessive toe-in or toe-out. In
CHEVROLET CHASSIS SERVICE MANUAL
CHASSIS SHEET METAL 11-18
b.
Check and adjust front wheel alignment as out-
lined in Section 3.
c. Check and adjust headlamp aiming as outlined in
Section 12.
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.

GENERAL DESCRIPTION
.
The lighting system includes: the main lighting switch,
stop light, dimmer, and backing lamp switches, head-
lamps, parking lamps, stop, tail and directional lamps,
instrument illumination and indicator lamps, and the
necessary wiring to complete the various circuits. A
fuse panel provides convenient power take offs and fuse
clips for the appropriate circuits (fig. 1).
Chevrolet and Chevelle headlamp installation is all
new in that the headlamps are located in the radiator
support with adjusting screws and springs. Eliminating
the need for having separate headlamp housings. Chev-
rolet and Chevelle headlamp retainers and springs are
interchangeable.
Chevy n headlamp housings are new because of revised
front end styling and Corvette front end lighting is basi-
cally carryover.
Front fender lamps have been added as an option for
Chevrolet models and as standard equipment on Caprice
series.
Camaro models use single headlamps and the Rally
Sport model headlamps are covered by a retractable
section of the grille when lamps are not used. The sec-
tion of the grille covering the headlamps folds back when
lights are required; the headlamps are stationary. The
covering is retracted by a small electric motor mounted
to the headlamp housing. The headlamps are automat-
ically uncovered when the headlight switch is pulled "ON"
for illumination. If at any time the electrical circuit
becomes inoperative, the lamps can be uncovered manu-
ally. The ignition switch must be
"ON"
in order to close
the headlamp doors.
Parking lamp for Chevelle and Chevrolet models are
new due to revised front end sheet metal and bumper
styling. Parking lamps are located in the bumper on
Chevrolet, Chevelle and Chevy n models
Camaro parking lamps are located in the radiator
grille except for the Rally Sport models on which the
parking lamps are in the valance panel. For styling
reasons, the lens is white and an amber glass bulb is
used. All Camaro parking lamps require a separate
ground wire to assure a good ground contact because of
the plastic grille and painted contact surfaces.
The Chevrolet tail, stop, and directional lamps are in
one housing with a three section lens design on Impala
and Caprice sedans. The center lens for Impala series
is the back-up lamp. The center lens on the Caprice is
a tail lamp with the back-up lamps being located in the
rear bumper. Chevrolet station wagons have three indi-
vidual housings with three lenses, the center lamp being
the back-up. Biscayne and Bel-Air sedans have a single
housing and lens for tail, stop, and directional lamp with
a similarly constructed back-up lamp inboard and adja-
cent to it.
Chevelle tail, stop, and directional lamps are a single
lens design that follows through with the rear fender
styling. The back-up lamp is located in r.ear bumper.
Camaro models except Rally Sport have tail lamps
with integral back-up lamps mounted inboard of the rear
fenders between the trunk opening and bumper. The
Rally Sport model has dual tail lamps in the rear housing
and valance mounted back-up lamps.
Corvette, Chevy n, and Corvair tail and directional
signal lights are carryover. The Corvette has new back-
up lamps center mounted above the license plate opening.
