low oil pressure CHEVROLET VEGA 1976 1.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine Generator Indicator Light
The red light will go on when
the ignition key
is in the "on" posi­
tion, but before the engine
is started.
After the engine starts, the light
should go out and remain out.
If
the light remains on when engine
is running, have your Authorized
Chevrolet Dealer locate and correct
the trouble
as soon as possible.
Temp. Pressure Indicator
Light
This indicator light is provided
in the instrument cluster to quickly
warn of an overheated engine
and/or extreme low oil pressure
or oil supply. This light will be on
when the ignition switch is turned
"ON" and should go out after the
engine
is started. Occasionally the
light may be seen to flicker momen­
tarily, but this will do no harm. Ex­
treme low oil pressure or oil supply
will prevent the electric fuel pump from
operating and under this con­
dition the engine will not run.
If the light comes on during ex­
treme driving conditions, such
as an
extended idle, turn off the air con­
ditioner (if used) and run the en­
gine slightly faster than idle speed
with the transmission in
neutral
gear. If the light does not go off
within a short period of time (1-2
minutes), then turn the engine off
until the cause of
the overheating is
corrected. Glance at the instrument
cluster frequently
as you drive to
see if this light is on.
Add Coolant Indicator Light
This indicator light is provided to
warn of a low coolant condition in
the radiator.
If coolant level is low
the yellow
"Add Coolant" warning
light will glow. Coolant level in the
coolant recovery tank, and radiator,
should be checked at the first oppor­
tunity.
If necessary add sufficient
2-15
coolant to both the radiator and
coolant recovery tank.
(See Service
and Maintenance, Section 5, for
proper procedure) .
If frequent
additions are required, see your
dealer for a complete cooling sys­
tem check.
Brake System Warning
Light
The service brake system is a dual
system designed so that one part will
provide some braking action in the
event of loss of hydraulic pressure
in the other part of the system.
If the
warning light labeled
"Brake" lo­
cated in the speedometer face comes
on and stays
on when the ignition is
on and after the brakes have been
firmly applied
it may indicate that
there
is a malfunction in one part of
the brake system.
• As a reminder, the light is de­
signed to come
on with the park­
ing brake applied and the igni­
tion on.

Trim Materials with
Solvent
Type Cleaner
Before attempting to remove
spots or stains from fabric, deter­
mine
as accurately as possible the
nature and age of the spot or stain.
Some spots or stains can be re­
moved satisfactorily with water or
mild soap solution (refer to ac­
companying
"Removal of Specific
Stains"). For best results, spots or
stains should be removed
as soon
as possible. Some types of stains
or soilage such
as lipstick, some
inks, certain types of grease etc.,
are extremely difficult and,
in some
cases, impossible to completely re­
move. When cleaning 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 careless cleaning.
G.M.
Spot Lifter (Solvent Type)
is excellent for spot cleaning stains
containing grease, oil or fats from
fabric type trim. Excess stain
should be gently scraped off trim
material with a clean DULL knife
or scraper.
USE VERY LITTLE
CLEANER, light pressure, and
clean cloths (preferably cheese
cloth). Cleaning action should be
from outside of stain FEATHER­
ING towards center of stain and
constantly changing· to a clean sec­
tion of cloth.
When stain is cleaned
from · fabric, immediately dry area
with an· air
hose, heat dryer or heat
l~mp to help prevent a cleaning
flng (use caution with heat dryer
or heat
lamp to prevent damage to
fabric material).
If a ring forms,
immediately repeat the
. cleaning
operation over a slightly larger
area with special emphasis on
FEATHERING towards center of
area.
If ring still persists, mark
off adjacent trim sections and clean
4-3
entire affected trim panel sectIOn
with G.M. Multi-Purpose Powdered
Cleaner
as previously described
under
"Cleaning General Soilage
or Water
Spots with Foam Type
Cleaner."
Removal of Specific Stains
Grease or Oil Stains-Includes
grease, oil, butter, margarine shoe
polish, coffee with cream,
ch~wing
gum, cosmetic creams, vegetable
oils, wax crayon, tar and asphalts.
Carefully scrape off excess stain;
then use Spot Lifter (Solvent
Type) as previously described.
Shoe polish, wax crayons, tar and
asphalts
will stain if allowed to
remain on trim; they should be
removed
as soon as possible-use
caution
as cleaner will dissolve
them and may cause them to bleed.
Non-Greasy Stains-Includes cat­
sup, coffee (black), egg, fruit, fruit

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 protection at -20o
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.
