Engine Exhaust Gas Caution (Carbon Monoxide)
Allold inhaling exhaust gases because
they contain carbon monoxide, which by
Itsell is colorless and odorless. Carbon
monoxide is a dangerous gas that can cause unconsciousness and is potentially
lethal.
II at any time you suspect that exhaust fumes are entering the passenger com­partment, have the cause determined and corrected as soon as possible. II you must
drive under these conditions, drive only
with
all windows fully open.
The best protection against carbon
mon­oxide entry into the car body is a properly
maintained exhaust system, car body and body ventilation system. It is recom­mended that the exhaust system and body
be inspected by a competent mechanic:
• Each time the IIehicie is raised for oil change. > •
Wheneller a change
is noticed In the
sound of the exhaust system.
• Wheneller the exhaust system, under­
body or rear of the vehicle is damaged.
See your Maintenance Schedule folder
for inspection procedure.
To allow proper operation of the car's
IIentilation system, keep front ventilation
inlet
grille clear of snow, leaves or other obstruction at all times.
SITTING IN A PARKED CAR WITH
ENGINE RUNNING FOR AN EXTENDED PERIOD IS NOT RECOMMENDED.
Do
not run engine in confined areas such as garages any more than needed to mOlle IIehicle In or out of area. When IIe­hlcle is stopped In an UNCONFINED area with the engine running for any more than a short period, adJust heating or cooling system to force outside air Into car as follows:
14
1. On cars not equipped with air condi­
tioning, set fan to medium or high
speed and upper control leller to any
position except OFF.
2. On cars equipped with manual air conditioning, set fan to medium or high speed, upper control lever to any
position except OFF, and lower con­trol lever to any position except ex­treme left COLD.
The trunk lid should be closed while
drilling to help prellent inadllertently draw­Ing exhaust gases Into the car. If Is unwise to drive at high speeds for long durations
with the trunk lid open. Howeller, If lor some reason the trunk must remain open lor a period while mOiling, or electrical wiring or other cable connections to a trailer must pass through the seal between
trunk lid and body, the lol/owlng precau­
tions should be observed:
• Close all windows.
• Ad/ust heating or cooling system to
force outside air into car as described In items 1 and 2 abolle but with Ian set at high speed.
• On cars equipped with outside aIr IIents In or under Instrument panel, open IIents lully.

Downloaded from www.Manualslib.com manuals search engine Basic Operating Tips:
• Always keep front inlet grille
clear of obstructions (leaves,
ice, snow, etc.).
• When heating or air condition­
ing
is desired, best comfort is
attained by driving with all win­
dows closed.
The following sections of this
33
manual provide additional operat­
ing tips for obtaining maximum
heating and cooling comfort.
(See
also Engine Exhaust Gas Caution
at beginning of this
Section.)

Downloaded from www.Manualslib.com manuals search engine Temperature (Lower Lever)
The temperature lever allows a
selection of air temperature from
Cold at the far left to Hot
at the far
right. When the temperature lever
is in the COLD position the system
will provide the coldest air possible.
When the temperature lever
is
moved to the right (toward HOT) ,
the system will operate on outside
air.
Selector (Upper Lever)
This lever provides a selection of
systems available to handle various
heating and cooling requirements
throughout the year. The Selector
lever has four
(4) major opera­
tional
positions-"Off," "Air Condi­
tioning," "Vent" and "Heating."
The "Air Conditioning" and "Heat­
ing"
groups have several positions
which improve the effectiveness of the
system for various demands.
OFF-The system operates on low
blower regardless of fan switch po­
sition with air discharged into
ve­
hicle through heater outlet.
A/C-Air from the passenger com­
partment
is recirculated through
the system with some outside air
and discharged from the upper out­
lets when the temperature lever
is
in Full COLD or extreme left. If
the Temperature lever is moved
right to the first stop or further, the
system will automatically go on
outside air. The
AIC position, with
Temp. lever in Full
COLD, is used
when maximum cooling
is required
under conditions of high tempera­
ture and humidity. High fan speed
is automatically attained in this
position .
36
A/C (with Temp lever right to first
stop) -Outside air
is passed
through the system and discharged
through the upper outlets. This po­
sition
is recommended for most air
conditioning situations because of
reduced blower noise and reduction
of cigarette smdke within the
ve­
hicle. Fan speed may be varied as
required.
VENT -Outside air is passed
through the system and discharged
from the upper and lower outlets.
This position
is provided for cool
to moderate weather when refrig­
eration
is not required.
HEATER-Outside air
is delivered
through the heater outlet and with
some air through the defroster out­
lets. Temperature may be adjusted
as required. This position is recom-

hinge assembly as follows:
1. Wipe off any accumulation of
dirt or contamination on latch
parts.
2. Apply Lubriplate or equivalent
to latch pilot bolts and latch
locking plate.
3. Apply light engine oil to all
pivot points in release mecha­
nism, as well
as primary and
secondary latch mechanisms.
4. Lubricate hood hinges.
5. Make hood hinge and latch
mechanism functional check to
assure the assembly
is working
correctly.
Air Conditioning
Have your Chevrolet 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

a
Pour Season Air Conditioning
System, the system will not operate
below ambient temperatures of
300P. regardless of control posi­
tion.
the summer,
see your Chevrolet
Dealer immediately if you suspect
the system
is not performing as it
should .
Cooling System Care
Check the coolant level at each
engine oil change.
Engine Cooling System
The recovery type cooling sys­
tem is standard on all Chevrolet
passenger cars and
is designed to
maintain the engine at proper op-
57
erating temperatures. The recovery
tank collects coolant that expands
with rising temperature that would
otherwi se overflow from the sys­
tem. When the system temperature
drops, the coolant
is drawn from
the recovery tank back into the
radiator by the suction created by
coolant contraction. The cooling
system has been filled at the factory
with a high-quality , inhibited, year­
around coolant that meets the stan­
dards of General Motors Specifica­
tion 1899-M. This coolant solution
provides freezing protection to
-20oP (-32° P in Canada), and
it has been formulated to be used
for two full calendar years or
24,000 miles, whichever first oc­
curs, of normal operation without
replacement.
Cooling System Care
Check the coolant level in the
'see thru' coolant recovery tank

Downloaded from www.Manualslib.com manuals search engine and in the radiator at least as fre­
quently
as engine oil changes.
NOTE: Do not remove radiator
cap when coolant
is hot and under
pressure.
Level should be at the
"FULL
COLD"
mark on the recovery tank
and at the bottom of the radiator
filler neck when the system
is cold.
During normal warm weather op­
eration the coolant should be at
the
"FULL HOT" mark on the re­
covery tank.
If the recovery tank is
empty or coolant is below the
"FULL COLD" mark the radiator
level should be checked and cool­
ant added to the radiator and re­
covery tank
as needed. Use a 50/50
mixture of high-quality ethylene gly­
col antifreeze and water for coolant
additions.
If regular additions are
required see your dealer for a cool­
ing system check.
NOTE: If recommended quaIily
antifreeze is used, supplemental in­
hibitors or additives claiming to
provide increased capability are
not necessary. They may be detri­
mental
to the efficient operation of
the system, and represent an un­
necessary operating expense.
Every year, the cooling system
should be serviced
as follows:
1 . Wash radiator cap and filler
neck with clean water.
2. Check coolant for proper
level and freeze protection.
3. Pressure test system and radi­
ator cap for proper pressure
holding capacity (15 psi).
If
replacement of cap is re­
quired, use the special AC
cap designed for coolant re­
covery systems, specified for
your car model.
4. Tighten hose clamps and in­
spect all hoses. Replace hoses
58
whenever swollen, checked or
otherwise deteriorated.
5. Clean frontal area of radiator
core and air conditioning
condenser.
Every two years or
24,000 miles,
whichever first occurs, the cooling
system should be flushed and re­
filled using the following recom­
mended procedure:
1. Run engine, with radiator cap
removed, until normal operat­
ing temperature
is reached
and upper radiator hose
is hot
(indicates thermostat
is open.)
2. Stop engine and open radiator
drain valve to drain coolant.
(To speed this operation, the
drain plugs in the block can
also be removed.)

Downloaded from www.Manualslib.com manuals search engine • Maintain cooling system freeze
protection at
.;...200 F or below
to ensure protection against
corrosion and loss of coolant
from boiling , even though freez­
ing temperatures are not
ex­
pected.
• Add ethylene glycol base cool­
ant that meets GM Specification
1899-M when coolant additions
are required because of coolant
loss or to provide additional
protection against freezing at
temperatures lower than
_200 F
(_320 F in Canada).
NOTE: Alcohol or methanol base
coolants or plain water are not
recommended for your Monte
Carlo 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 checked periodically for
proper operation.
If replacement is
required specify AC.
Thermostat
The cooling system is protected
and controlled by a thermostat in­
stalled in the engine coolant outlet
to maintain a satisfactory operating
temperature of the engine. This
thermostat
is designed for continu­
ous use through both winter and
summer and need not be changed
seasonally . When replacement
is
necessary, Delco parts are recom­
mended.
60
Tires
The factory installed tires on
your car
as shown on the following
Tire Usage chart are designed to
provide the best all around per­
formance for normal vehicle op­
eration. When inflated
as recom­
mended on the tire pressure plac­
ard, located on the left door of
your vehicle, they have the load
carrying capacity to operate satis­
factorily at all normal highway
speeds.
Tire Care
Tires should be checked regu­
larly for proper inflation pressure,
wear, and damage. The following
information will assist you in prop­
erly caring for your tires:

Downloaded from www.Manualslib.com manuals search engine a bobby pin) between the rubber
cup
at the end of the spark plug
wire
and the tubular metal con­
nector inside
of it. If the spark plug wire is wet or oily, wipe it
dry.
Wrap a dry handkerchief or
facial tissue, folded several thick­
nesses,
around the wire at least
three inches back from the end and grasp the wire at this point.
Hold the bare wire about V4 inch
from the
bore tip of the spark plug from which you removed the Checking Spark
wire. When the engine is "turned over" a spark should jump across
the 1,4 inch space, indicating ample current supply. If no spark
jumps, the difficulty is probably caused by a defective ignition part
and should be corrected by your Authorized Chevrolet Dealer.
COOLING SYSTEM
When the car will run but evidences serious overheating on the
temperature gauge in the instrument panel, there are several items
which may
be checked.
IL) Engine overheating will occur when the OIL LEVEL falls danger­
ously low. Check the oil level as a mailer of course.
1M) Low COOLANT LEVEL will, of course, cause engine over­
heating . Determine the
cause of the low coolant level and have it corrected if necessary.
70
IN) Check the RADIATOR CORE. Clean it if it is plugged with
bugs, leaves or other foreign material.
(0) Condition of the FAN BELT
is very important, not only for en­
gine cooling but
also for proper
generator operation. Check the
condition of the belt. Replace it
if it is worn or frayed. Loosen
the generator toward the engine
to remove
and replace the belt.
Tighten the belt, whether new or
old, by loosening the generator
bolts, prying with a bar on the
generator until the belt is ten­
sioned properly , then retighten
the
generator bolts.

not permit
coolant to circulate
through the system. In such an
emergency the thermostat may be
