1973 CHEVROLET CAMARO radiator cap

Downloaded from www.Manualslib.com manuals search engine type cooling system is used on all
1973 Camaro air conditioned and
heavy duty cooling systems. It has
been filled at the factory with a
high-quality, inhibited, year-around
coolant that meets the standards
of General Motors Specification
1899-M. This coolant solution pro­
vides freezing protection to
-20 0 F
(-32°F in Canada), and it has
been formulated to be used for
two full calendar years
or 24,000
miles, whichever first occurs, of
normal operation without draining,
provided the proper concentration
of coolant
is maintained.
• For Recovery Systems Only­
Check the coolant level visually
at the see-through coolant reser­
voir at each oil change interval
while the engine
is at normal
operating temperature. Do not
remove radiator cap except for
draining and refilling the system.
Coolant level should be at the
"Full Hot" mark on the reservoir.
If system is checked cold, the
coolant level should be at the
"Full Cold" mark on the reser­
voir.
• For Other Than Recovery Sys­
tems-Check the coolant level
only at oil change intervals, un­
less there
is evidence of leaking
or overheating. Do not remove
radiator cap when solution
is
hot and under pressure. Coolant
level should be a maximum of
three inches below the level of
the filler neck when the engine
is cold.
• All Systems-Add a 50/50 mix­
ture of high-quality ethylene
glycol antifreeze and water if
coolant additions are necessary.
Do not overfill.
NOTE: If recommended quality
antifreeze
is used, supplemental
inhibitors or additives claiming to
53
provide increased cooling capabil­
ity are not necessary. They may be
detrimental to the efficient opera­
tion of the system, and represent
an unnecessary 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 radia­
tor cap for proper pressure hold­
ing capacity (15 psi).
If re­
placement
of cap is required,
use the proper AC cap specified
for your car model.
4. Tighten hose clamps and inspect
all hoses. Replace hoses when­
ever checked, swollen
or other­
wise deteriorated.
5. Clean frontal area of radiator
core and air conditioning con­
denser.

Downloaded from www.Manualslib.com manuals search engine Every two years or 24,000 miles,
whichever first occurs, the cooling
system should be drained by si­
phoning
and refilled as follows :
1 . Run engine, with radiator cap
removed , until normal operat­
ing temperature
is reached
and upper radiator
is hot (in­
dicates thermostat
is open).
2. With engine stopped, insert
one end
of a 5-foot length of
¥s inch tubing into the filler
neck until it touches the bot­
tom of the radiator.
3. Insert any type of large sy­
ringe into the open end of the
tubing and initiate the siphon­
ing process by squeezing and
releasing the ball.
4. Completely drain radiator
coolant through the siphon
tube.
(To speed this opera­
. tion the drain plugs in block
can also be removed.)
4A. For recovery systems use
same method to siphon all
coolant from reservoir.
5. Remove tubing (install block
drain plugs, if removed) and
add sufficient water to fill
system.
6. Run engine, drain and refill
the system, as described in
steps
1 thru 5, a sufficient
number of times until the
drained liquid
is nearly color­
less.
7. Allow system to drain com­
pletely and install block drain
plugs, if removed.
8. Coolant Recovery Systems
Only
- Flush reservoir with
clean water,
and drain.
54
9. Add sufficient ethylene glycol
coolant, meeting
GM Specifi­
cation 1899-M, to provide
the required freezing and
corrosion
protection-at least
a
44 percent solution (-200
F). For both standard and
recovery systems, fill radiator
to the cold fill level
(3" be­
low bottom
of filler neck).
For recovery systems, add
sufficient coolant to reservoir
to raise level to
"Full Hot"
mark.
I O. Run engine, with radiator cap
removed, until normal oper­
ating temperature
is reached.
(Radiator upper hose be­
comes
hot.)
11. With engine idling, add cool­
ant to within 1 V:z " below bot­
tom of filler neck and install
radiator cap making certain
arrows line
up with overflow
tube.

Downloaded from www.Manualslib.com manuals search engine It is the owner's responsibility
to keep the freeze protection at a
level commensurate with the tem­
peratures which may occur
in the
area of vehicle operation.
• Maintain cooling system freeze
protection at
_200 F or below
to ensure protection against cor­
rosion and loss of coolant from
boiling, even though freezing
temperatures are not expected.
• 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 Camaro 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 periodi­
cally for proper operation.
If re­
placement
is required specify AC.
Thermostat
The cooling system is protected
and controlled by a thennostat
in­
stalled in the engine coolant outlet
to maintain a satisfactory operat­
ing temperature of the engine. This
thermostat
is designed forcontinu­
ous use through both winter and summer
and need not be changed
seasonally . When replacement
is
necessary, Delco parts are recom~
mended.
Tires
The factory installed tires on
your car
as shown in the Tire
Usage chart below are designed to
provide the best all around per­
formance for normal vehicle oper­
ation. 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.
