The time or mileage intervals on
the following pages are intended
as a guide for establishing regular
maintenance and lubrication per­
iods for your car. Sustained heavy
duty or high speed operations or
operation under adverse conditions
may necessitate more frequent ser­
vicing.
To determine specific rec­
ommendations for conditions un-
Fuel

Your Chevrolet engine is de­
signed to operate
only on unleaded
gasoline. Unleaded gasoline is essen­
tial for proper emission control
system operation, and it will mini­
mize spark plug fouling. The

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:

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.

Automatic Transmission­
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 overfill¢ 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.

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

Automatic Transmlssion­
Drain
Intervals
The transmission operating tem-perature
resulting from the type of
driving
conditions under which
your vehicle
is used is the main
consideration in establi shing the
proper frequency of transmission

SYSTEM
The recovery type cooling sys­
tem is standard on all Chevrolet
pasSenger cars. The coolant ex~
pands with rising temperature and
the overflow
is dOllected in the
recovery tank.
When the system
temperature drops, the coolant is
drawn back
intocthe radiator. The
cooling system has been filled at
the factory with a high-quality, in­
hibited , year-around coolant that
meets the standards
of General
Motors Specification I
899"M. This
coolant solution provides freezing
protection
to -20oP (-28°C),
and in Canada to _35°P
( -37°C), and it h~s been formu­
lated to be used without replace­
ment for two years or 30,000 miles.
After two years
or 30,000 miles,
the coolant should be drained to
prevent rust or corrosion in the
radiator and engine.
Cooling System Care
Do not remove radiator cap to
check coolantlevel , but
checkvisu­
ally in the "see 'thru " coolant re­
covery tank at least as frequently
as ,needed. LeveL should be at the
"full cold" mark on the recovery
tank when the system
is cold and
at the
"full hot" roark at Iiormal
operating temperature. Add'~ 501
50 mixture of high-quality ethylene
glycol antifreeze and
waler for
coolant additions.
If frequent addi­
tionsare required, see your dealer
for
a cooling system check.
NOTE: If recommended quality
antifreeze
is used,supplemental in­
hibitors or additives claiming to
provide increased capability are
not
necessary. They may be detrimen­
tal to the efficient operation of the
system, and represent an
unneces­
sary operating expense.
5-7
The cooling system should be
serviced every year as follows:
1. Wash radiator cap and filler neck
with clean water.
2. Check coolant for proper level
and freeze protection.
3. Test system
and radiator cap for
, properpresslire holding capacity
(15 psi).
Ifreqitired, use cap
designed by
AC for coolant re­
co~ery systems, and specified for
your model.
4, Tighten hose clamps and
inspect
all hoses. Replace hoses if swol­
len, checked or otherwise deteri­
orated.
5. Clean frontal area of radiator
, qcire and air conditioning con­
denser.

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. Rem()ve radiator cap when en­
gineis 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.

8. Add sufficient ethylene glycol
coolant, meeting
OM 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.

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
