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.

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.
