For owner convenience, a sep

provided with your car which con

brief explanation of the safety,
emission control, lubrication and
anti-knock quality will result
in
"spark knock", a metallic rapping
noise generated during the
com

that Research
Octane Number
does not completely describe fuel
octane quality. Therefore ,
if you

may wish
to try a different gaso
line.
If knocking persists consult

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.
