COOLANT

Note

The

permanent
anti

coolant
is
an

ethylene
glya
l
base

product

containing
chemical
in

hibitors
to

protect
the

cooling

system
from

rusting
and
corrosion

The
anti

freeze
does
not
cOntain

any
glycerine
or

ethyl
alcohol
It

will
not

evaporate
or
boil
a

ay
and

can
be

ilsed
with
either

high
or
low

temperature
thermostats
It

flows

freely
transfers
heat

efficiently

and
will
not

clog
the

passages
in

the

cooling

system
The
anti
freeze

must
not
be
mixed

with
other

product
This
coolant
can
be
used

throughout
the
seasons
of
the

year

Whenever
coolant
is

changed
the

cooling

system
must
be
flushed
and

refilled
with
a
new
coolant
Check
the

coolant
