VALVE
OPERATION: All General Motors gasoline engine
powered vehicles are equipped with Positive
Crank
case Ventilation-a system which permits no crank
case emissions to be discharged into the atmosphere.
To function properly, the system depends on the
43
PCV Valve which returns blow-by gases to the com
bustion chamber where they are burned.
MAINTENANCE: This valve must be clean in
order to maintain efficient engine operation.
An
inspection of the ventilation filter should be
made at the first oil change
(4 months or 6,000
miles, whichever occurs first). At each subse
quent oil change, the ventilation filter
should
be inspected and replaced if necessary. Re
place filter at least every 24,000 miles. Under
normal driving conditions, the PCV Valve should
be replaced every 24 months or 24,000 miles,
whichever occurs first, and
all hoses and fit·
tings
should be inspected and cleaned or re
placed, as necessary. Replace the PCV Valve
and inspect related parts every 12 months or
12,000 miles when the vehicle is used in a ser
vice requiring more frequent engine oil change
as covered on page 53.
NOTE: Emission control systems in this section are Illustrated on V-8 engines; systems on 4 and 6 cylinder engines are similar.

OPERATION: The Controlled Combustion System

.... ~!~:~~A:~~~~I:E ~ TREATED EXHAUST ~(TOUMOS'HERE THMOUGHHHAlIST'II'E)
OPERATION: The Air Injection Reactor system,
(used on vehicles not equipped with
CCS) is de
signed to reduce air pollution by oxidizing (burning)
the hydrocarbons and carbon monoxide after they
45
leave the combustion chamber. A positive displace
ment air pump, driven by the engine, compresses
filtered air which
is injected at the exhaust port of
each cylinder. This air mixes with the exhaust gases
and promotes further oxidation of both hydro
carbons and carbon monoxide. The
AIR system also
includes a specially calibrated carburetor and dis
tributor.
MAINTENANCE: Complete effectiveness of this
system
is dependent on the engine idle speed,
ignition timing and
dwell being set according
to specifications as indicated on a label under
the hood. These adjustments should be
checked at the first oil change (4 months or
6,000 miles, whichever comes first). Subse
quent checks should be made at 12 months or
12,000 mile intervals, whichever comes first.
These adjustments are
also included as part of
the
quality tune-up recommended at the same
intervals. In addition, all hoses and fittings
should be inspected to make sure they are
properly connected, and the drive belt in
spected for wear
and tension on the 12 month
or
12,000 mile schedule.

Care and Cleaning
of Interior Soft Trim
Dust and loose dirt that accumu
late on interior fabric trim should
be removed frequently with a
vac
uum cleaner, whisk broom or soft
brush. Vinyl
or leather trim should
be wiped clean with a damp cloth.
Normal cleanable trim soilage,
spots or stains can be cleaned with
the proper use of trim cleaners
available through General Motors
dealers
or other reputable supply
outlets. Before attempting to
re
move spots or stains from uphol
stery, determine as accurately as
possible the nature and age of the
spot
or stain. Some spots or stains
can be removed satisfactorily with
water
or mild soap solution (refer
to accompanying
"Removal of Spe
cific Stains"). For best results, spots
or stains
should be removed
as soon as possible. Some types of
stains
or soilage such as lipsticks,
some inks, certain types of grease,
mustard, etc., are extremely
diffi
cult and, in some cases, impossible
to completely remove. When
clean
ing this type of stain or soilage, care
must be taken not to enlarge the
soiled area.
It is sometimes more
desirable to have a small stain than
an enlarged stain as a result of
care
less cleaning.
47
CAUTION: When cleaning Interior soft trim such as upholstery or carpeting, do
not use volatile cleaning solvents such
as: acetone, lacquer thinners, carbon tet
rachloride, enamel reducers, nail polish
removers; or such cleaning materials .s
laundry soaps, bleaches or reducing
agents (except as noted in the Instruc
tions on stain removal). Never use gaso
line or naphtha lor any cleaning purpose.
These
materl./s may be toxic or flam
mable, or may cause damage to Interior
trim.

Downloaded from www.Manualslib.com manuals search engine Cleaning Fabrics with
Cleaning Fluid
This type of cleaner should be
used for cleaning stains containing
grease, oil
or fats. Excess stain
should be gently scraped off with
a clean dull knife
or scraper. Use
very little cleaner, light pressure,
and clean cloths (preferably cheese
cloths). Cleaning action with cloth
should be from outside of stain to
wards center and constantly chang
ing to a clean section of cloth.
When stain
is cleaned from fabric,
immediately wipe area briskly with
a clean absorbent towel
or cheese
cloth to help dry area and prevent
a cleaning ring.
If ring forms, im
mediately clean entire area
or panel
section of the trim assembly.
NOTE: Sometimes a difficult spot
may require a second application
of cleaning fluid followed immedi
ately by a soft brush to completely
remove the spot.
Cleaning Fabrics with
Detergent Foam
Cleaners
This type of cleaner is excellent
for cleaning general soilage from
fabrics and for cleaning a panel sec
tion where a minor cleaning ring
may be left from spot cleaning.
Vacuum area to remove excess
loose dirt. Always clean at least a
full trim panel
or section of trim.
Mask adjacent trim along stitch
or
weld lines. Mix detergent type foam
cleaners in strict accordance with
directions
on label of container.
Use foam only on a clean sponge or
48
soft bristle brush - Do not wet
fabric excessively or rub harshly
with brush. Wipe clean with a
slightly damp absorbent towel
or
cloth. Immediately after cleaning
fabric, dry fabric with a dry towel
or hair dryer. Rewipe fabric with
dry absorbent towel
or cloth to re
store the luster of the trim and to
eliminate any dried residue.
Removal of Specific Stains
Candy -Chocolate, use cloth
soaked in lukewarm water; other
than chocolate, use very hot water.

Washing Your Car
The best way to preserve the
finish and maintain original beauty
of appearance
is to keep it clean .
Wash the car in lukewarm
or cold
water. Never use strong soap or
chemical detergents. Cleaning
agents should be quickly flushed
from the surfaces.

If odor persists,
treat area with a water-baking soda
solution (1 teaspoon baking soda
to one cup of tepid water). Rub
again with cloth and cold water.
Finally,
if necessary, clean lightly
with fabric cleaning fluid.
Polishing and Waxing
Your Car
Although acrylic paint on your
car
is durable, you may wish to wax
or polish for added protection.
Your Chevrolet Dealer offers many
polishes and waxes now available
which have proven of real value in
maintaining a good paint finish.

Downloaded from www.Manualslib.com manuals search engine When using a tar and road oil re
mover, be certain it
is safe for use
on acrylic painted surfaces.
Protection of Exterior
Bright
Metal Parts
Bright metal parts should be
cleaned regularly to maintain lus
ter. Washing with water
is all that
is usually required. However, G.M.
Chrome Polish may be used on
CHROMEorSTAINLESS STEEL
trim
if necessary.
Use special care with ALU
MINUM trim. Never use auto or
chrome polish, steam or any caustic
soap to clean aluminum.
A coating of wax, rubbed to a
high polish,
is recommended for all
bright metal parts.
Cleaning White Sidewall
Tires
Use a tire cleaner which will not
harm aluminum trim. A
stiff brush
may be used with the cleaner to
remove road grime and dirt from
white sidewall tires.
Cleaning the Optional
Vinyl
Top
The top should be washed fre
quently with neutral soap suds,
lukewarm water and a brush with
soft bristles. Rinse top with
suffi
cient quantities of clear water to re
move all traces of soap.
If the top requires additional
cleaning after using soap and water,
a mild foaming cleanser can be
used. Rinse the whole top with
water; then apply a mild foaming
50
type cleanser on an area of approx
imately two square feet. Scrub area
with a small soft bristle hand brush,
adding water
as necessary until the
cleanser foams
to a soapy consis
tency. Remove the first accumu
lated soilage with a cloth or sponge
before it can be ground into the top
material. Apply additional cleanser
to the area and scrub until the top
is clean. Care must be exercised to
keep the cleanser from running onto
body finish
as it may cause streaks
if allowed to run down and dry.
After the entire top has been
cleaned , rinse generously with clear
water to remove all traces of
cleanser. Do not use volatile cleaner
or household bleaching agents on
the top material.
