Maintenance
More frequent vehicle mainte­
nance
is required when using your
car
to pull a trailer. Change. the:
• Automatic transmission fluid
and filter each 15,000 miles,
(see Trai/ering brochure foraddi­
tional information).
.• Rear axle fluid each 15,000
miles,
• Engine oil each 90 days or 3,000
miles , whichever occurs first,
• Positive crankcase ventilation
valve each
12 months or 15,000
miles, whichever occurs first.
• See index for important informa­
tion on belts, cooling system care
and automatic brake
adjuslrilent.
Break·in Schec;!ule
In addition to the new car break-in
instructions in this manual, it
is
recommended that your new car
be operated for 500 miles before
trailer towing.
If it is necessary to
tow during this period, avoid speeds
over
50 MPH and full throttle
starts. The same precautions should
be observed whenever a new
en­
gine , transmission or axle is in­
stalled in your car.

Downloaded from www.Manualslib.com manuals search engine Gas Cap-The fuel tank filler cap
has a
"Screw-on ratcheting type"
feature for proper gas tank sealing.
To remove:
• Rotate ~ap counterclockwise to
clear
the inside of the filler neck.
This will allow any residual
pres­
sure t!J escape.
• To iQstall, reverse this procedure
and . tighten cap securely until a
"ratcheting", . clicking sound is
heard indicating proper cap to
filler neck sealing.
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 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
ternperatures( engine not
thoroughly warmed-up).
'Under these conditions, change oil
each 3 month s
or 3,000 miles,
whichever occurs first.
• Operation in dust stOmlS 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 undetthe provisions
of the New Vehicle Warranty.
NOTE: Non-detergent and other
low quality oils are
sgecifically 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-irtstalled oil prior to the
recommended normal chartge 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
becom e sea ted.
Recommended Viscosity
To help assure good cold and hot
starting, as well as maximum en­
gine life, fuel economy and oil
economy , select the proper oil vis­
cosity for
the temperature range
anticipated from the following
chart:

NOTE: SAE 5W-30 oils· are rec ommended for all seasons in vehi­cles normally operated in Canada. SAE 5W-20oi ls are nol recommended fur su stained high-speed driving. SAE 30 oi ls may be used at tempera tures above 4O"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.
Re sea t the gauge firmly after taking
the reading.

protection at-20op (-2S0C) or
below to ensure pro;tection against
corrosion and loss
of coolant
from boiling even though freezing '
temperatures are not expected.
• Add ethylene glycol base coolant
that meets
GM Specification
IS99-M when coolant additions
are required because of coolant
loss
Or to provide additional pro"
tection against freezing at tem_
peratures lower than _20oP,
(-2S0C),' and in Canada to
_35°P ( -3JOC).
NOTE: AlcOhol Or methanol base
coolants or plain water are not
recommended for your vehicle at
any time.
Radiator Pressure Cap
The radiator cap, a 15 lb. pres­
sure type, must be installed tightly,
otherwise coolant may be lost and
damage
, to engine may result from
overheating. Radiator pressure caps
should
be chef'ked 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
arid is designed for
continuous use through both winter
and
s ·ummer. When replacement is
necessary, Delco parts are recom­
mended.
