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.

dark roads since they provide ex
cellent long range illumination. The
headlight beam indicator will be on
whenever the high beams or
"brights" are in use. The Headlight
Beam
Switch controls the headlight
beams (see Page
2-12).
Light Switch
The three position light switch
controls the headlights, taillights,
parking lights, side marker lights,
instrument lights and dome lights
as shown. The headlamp circuit
is protected by a circuit breaker in
the light switch.
An overload on
the breaker will cause the lamps to
"flicker" on and off. If this condi
tion develops, have your headlamp
wiring checked immediately.
Clock

resettings, several days apart, may
be needed to properly adjust the
clock mechanism. Have your clock
cleaned and oiled by a competent
clock serviceman at least every two
years.

Optional Instruments and
Gauges
Tachometer
The optional Tachometer indi
cates the speed of the engine in
revolutions
per minute.
Engine Temperature Gauge
This optional gauge indicates
coolant temperature which will vary
with air temperature and operat
ing conditions.
The ignition switch
must be on for accurate readings.
Hard driving
or prolonged idling in
very hot weather will cause the
pointer to move beyond the center
of the band. Should pointer move
to the line at the right end of the
band, stop engine or reduce speed
to permit engine to cool.

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 collected in the
recovery tank. When the system
temperature drops, the coolant
is
drawn back into the 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
Motor s Specification 1899-M. This
coolant solution provides freezing
protection to
-20oP (- 28 °C),
and in Canada to -35°P
(-37°C), and it has 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 coolant level, but check visu
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" mark at normal
operating temperature.
Add a 50/
50
mixture of high-quality ethylene
glycol antifreeze and water for
coolant additions.
If frequent addi
tions are 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
proper pressure holding capacity
(15 psi). If required, use cap
designed by
AC for coolant re
covery 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
core and air conditioning con
denser.
Page 66 of 87
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
Page 67 of 87
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.
