Use of Tire Chains
Tire chains may be used on your

Vega
is equipped with 13" x 6"
wheels, it cannot be modified to
accept tire chains.

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 Every two years or 30,000 miles,
whichever occurs first, the cooling
system should be· flushed and re­
filled using
the following recom­
mended procedure:
1. Remove radiator cap when en­
gine
is cool:
• Rotate cap slowly counter­
clockwise to detent
(Do not
press down while rotating.)
• Wait until residual pressure
(indicated by a hissing
sound) is relieved, then press
down on cap and continue
to rotate counterclockwise.
2.
Run engine, with radiator cap
removed, until upper radiator
hose
is hot (indicates thermo­
stat
is open). 3.
Stop engine
and open radiator
valve to drain coolant. (Opera­
tion may be speeded by remov­
ing drain plugs in the block.)
4. Close valve (install block drain
plugs, if removed) and add
sufficient water to
fill system.
5. Repeat steps 1, 2, 3, and 4, a
sufficient number of times until
the drained liquid is nearly
colorless.
6. Allow system to drain com­
pletely and then close radiator
drain valve tightly. (Install
block drain plugs, if removed.)
7. Remove recovery cap leaving
hoses in place. Remove coolant
recovery tank,. empty fluid,
scrub and clean bottom and
sides of tank with detergent and
water, flush well with clean
water, drain and reinstall.
5-8
8. Add sufficient ethylene glycol
coolant, meeting
GM Specifica­
tion 1899-M, to provide the re­
quired freezing and corrosion
protection-at least a 50 per­
cent solution
-34°F, -37°C.
Fill radiator to the base of the
radiator filler neck and bring
level of coolant in the recovery
tank to the
"FULL HOT"
mark. Reinstall recovery tank
cap.
9.
Run engine, with radiator cap
removed, until radiator upper
hose becomes hot.
10. With engine idling, add coolant
to radiator until level reaches
bottom of filler neck; install cap
making certain arrows line up
with overflow tube.
It is the owner's responsibility to:
• Maintain cooling system freeze

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.

Air Conditioning
Have your Authorized Dealer
check your Air Conditioning
sys­
tem at some time during the winter
months to be sure there has been
no loss in cooling output. During
the summer , see your Authorized
Dealer immediately if you suspect
the system
is not performing as it
should.

ing system will not operate below
ambient temperature of
300 F
( -1 0 C) , regardless of control
position.

An Air Conditioning high blower fuse, 30 amp. is located in an In-line fuse holder running from horn relay to Air Conditioning relay.
Do not use fuses of higher amperage rating than those recommended above.
Fusible Links are incorporated into the wiring system, These are wires of such a gauge that they will fuse (or melt) before damage occurs to an entire wiring harness in the event of an electrical overload. See your Chevrolet Dealer if fusible link replacement becomes necessary.
