1976 CHEVROLET MONTE CARLO radiator cap

Downloaded from www.Manualslib.com manuals search engine ENGINE COOLING
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.

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.
5-8
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.
9.
Run engine, with radiator cap
removed, until .radiator upper
hose becomes hot.
I
O. With engine idlil)g, 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

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.
