COOLANT
Note
The
permanent
anti
freeze
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
level
