1976 CHEVROLET VEGA oil

Downloaded from www.Manualslib.com manuals search engine If the top requires additional
cleaning after using soap and
water, a mild foaming cleanser can
be used such
as GM Multi-Purpose
Powdered Cleaner. Rinse the whole
top with water; then apply a mild
foaming type cleanser on an area of
approximately two square feet.
Scrub area with a small soft bristle hand
brush, adding
wa~er as neces­
sary until the cleanser foams to a
soapy consistency. Remove the first
accumulated soilage with a cloth
or sponge before it can be ground
into the top material. Apply addi­
tional cleanser to the area and
scrub until the top
is clean. Care
must be exercised to keep the
4-6
cleanser running onto body finish
as it may cause streaks if allowed
to run down and dry. After the en­
tire top has been cleaned, rinse gen­
erously with clear water to remove
all traces of cleanser. Do not use
volatile cleaner or household bleach­
ing agents on the top material.

Downloaded from www.Manualslib.com manuals search engine Gas Cap-The fuel tank filler cap
has a
two-step removal and in­
stallation procedure plus a pres­
sure-vacuum safety relief valve. It
is equipped with a double set of
locking tangs. To remove:
• Rotate cap one-half tum counter­
clockwise to clear the first set of
tangs from the slots inside the
filler neck. This will allow any
residual pressure to escape.
• Pull the cap outward and rotate
one-quarter
tum counterclock­
wise to clear second set of tangs
and remove the cap.
• To install, reverse this procedure.
NOTE: If this cap requires a re­
placement, only a cap with these
same features should be used.
Fail­
ure to use the correct cap can result
in a serious malfunction of the
sys­
tem. Correct replacement caps may
be obtained from your authorized
Chevrolet dealer.
ENGINE ITEMS
Engine Oil and Filter
Recommendations'
• Use only SE engine oil.
• Change oil each 6 months or
7,500 miles, whichever occurs
first,
except under the following
conditions:
*
-driving in dusty conditions
-trailer pulling
-extensive idling
-short-trip operation at
freez­
ing temperatures (engine not
thoroughly warmed-up) .
*Under these conditions, change oil
each 3 months
or 3,000 miles,
whichever occurs first.
• Operation in dust storms may
require an immediate oil change.
• Replace the oil filter at the first
oil change, and every second oil
change thereafter. AC oil filters
5-2
provide excellent engine pro­
tection.
See your Chevrolet dealer for
ad­
vice on the frequency of oil and
filter changes under unusual driving
conditions.
The above recommendations
ap­
ply to the first change as well as
subsequent oil changes. The oil
change interval for your Chevrolet
engine
is based on the use of SE
oils and quality oil filters.
Oil
change intervals longer than those
listed above will seriously reduce
engine life and may affect
Chevro­
let obligation under the provisions
of the
New Vehicle Warranty.
NOTE: Non-detergent and other
low quality oils are specifically not
recommended.
Only the use of SE
engine oils and proper oil and filter
change intervals assure you of
con­
tinued proper lubrication of your
Chevrolet engine.

Downloaded from www.Manualslib.com manuals search engine A high quality SE oil was in­
stalled in your engine at the factory.
It is not necessary to change this
factory-installed oil prior to the
recommended normal change pe­
riod. However, check the oil level
more frequently during the break­
in period since higher oil consump­
tion
is normal until the piston rings
become seated.
Recommended Viscosity
To help assure good cold and hot
starting, .
as well as maximum en­
ginelife, fuel economy and oil
economy, select the proper oil
vis­
cosity for the temperature rang¥
anticipated from the following
chart:

TEMPERATURE RANGE ANTICIPATED BEFORE 'NEXT OIL CHANGE
NOTE : SAE 5W-30 oils are recommended for all Seasons in vehi­cles normally operated in Canada. SAE 5W-20 oils are not
recommended for sustained high-speed driving. SAE 30 oils may be used at temperatures above 40°F. (4°C.)

Checking Engine Oil Level
The engine oil should be main­
tained at proper level. The best
time to check it
is as the last step in
a fuel stop. This will allow the oil
accumulation in the engine to drain
back in the crankcase. To check the
level, remove the oil gauge rod (dip
stick), wipe it clean and reinsert it
firmly for an accurate reading. The
oil gauge rod is marked "FULL"
and "ADD." The oil level should be
maintained in the safety margin,
neither going above the
"FULL"
line nor below the "ADD" line.
Reseat the gauge firmly after taking
the reading.

Downloaded from www.Manualslib.com manuals search engine Supplemental Engine Oil
Additives
The regular use of supplemental
additives
is specifically not recom­
mended and will increase operat­
ing costs. However, supplemental
additives are available that can
ef­
fectively and economically solve
certain specific problems without
causing other difficulties.
For ex­
ample, if higher detergency is re­
quired to reduce varnish and sludge
deposits resulting from some un­
usual operational difficulty, a thor­
oughly tested and approved addi­
tive-"G.M. Super Engine Oil Sup­
plement" -is available at your Chev­
rolet dealer.
In the event of an
operational problem, consult your
dealer for advice before using sup­
plemental additives.
Air Cleaner
When replacement of Air Cleaner
filter element
is necessary, an AC
ACron air filter element
is recom­
mended.
Drive Belts
Every 12 months or 15,000
miles-inspect drive belts for wear,
fraying, cracking, and tension. Belts
which are in
pOQr condition should
be replaced immediately.
Check tension by applying mod­
erate thumb pressUre midway be­
tween pulleys.
If the center-to­
center distance between pulleys
is
5-4
13 to 16 inches, the belt should de­
flect
'h inch. If the center-to-center
distance
is 7 to 10 inches, the belt
should deflect
~ inch. Loose belts
should be retensioned to give the
correct deflection.

Automatic Traiismission­
Fluid Level
Recommendations
Use automatic transmission
fluids identified with the mark
DEXRON®-II available from your
Chevrolet dealer or local service
station.
Check the fluid level at each en­
gine oil change period.
Automatic transmissions are fre­
quently overfilled because the fluid
level
is checked when the fluid is
cold and the dipsick indicates fluid
should
be added. However, the low
reading may be normal since the
fluid level will rise
as the fluid tem­
perature increases. A level change
of over
% inch will occur as fluid
temperature rises from
60° F. to
180° F. (16° C. to 82° C.)
Overfilling can cause foaming
and loss of fluid through the vent.
(65' -85'F .) (18 ' -29'C.) COOl HOT
WARM
NOTE: DO NOT OVERFill. It takes only 'one pint to raise level from ADD to FUll with a hot transmission.
Slippage and transmission failure
can result.
Fluid level too low can cause
slipping,
particularly when the
transmission is cold or the car is
on a hill.
Check the transmission fluid
level with the
engine running, the
shift lever in
Park, and the car
level.
Remove the dipstick and touch
the transmission end of the dipstick
NOTE: If the vehicle has recently
been operated for an extended
period at high speed or in city
traffic in hot weather
or the vehi­
cle
is being used to pull a trailer,
an accurate fluid level cannot be
determined until the fluid has
cooled dpwn-usually about 30
minutes after the vehicle has been
parked.)
cautiously to find out if the fluid
is
cool, warm or hot.
Wipe it clean and re-insert until
cap seats. Remove dipstick and
note reading.
• If the fluid feels cool, about room
temperature
(65° F. to 85° F.)

P (-28°C) or
below to ensure protection against
corrosion
and · loss of coolant
from boiling even though freezing
temperatures are not expected.
• Add ethylene glycol base coolant
that meets
GM Specification
1899-M when coolant additions
are required because of coolant
loss
or to provide additional pro­
tection against freezing at tem­
peratures lower than -20oP
(-28°C), and in Canada to
-35°P (-37°C).
NOTE: Alcohol or methanol base
coolants or plain water are not
recommended for your vehicle at
any time.
Your vehicle, if equipped with
standard 4-cylinder engine, has
an aluminum cylinder block.
When adding anti-freeze, rust
inhibitors, or cleaners, make
certain they are safe for
use
with aluminum components.
Radiator Pressure Cap
The radiator cap, a 15 lb. pres­
sure type, must be installed tightly,
otherwise coolant may be lost and
damage
t6 engine may result from
overheating. Radiator pressure caps
should be checked periodically for
proper operation.
If replacement is
required specify AC.
Thermostat
The cooling system is protected
and controlled by a thermostat that
maintains a satisfactory engine
operating temperature. This
ther­
mostat is installed in the engine
coolant outlet and
is designed for
continuous use through both winter
and summer. When replacement
is
necessary, Delco parts are recom­
mended.
