PERMANENT ANTI FREEZE
COOLANT
Permanent
anti
freeze
coolant is an
ethylene glycol
base
producl
conlain

chemical
inhibilors 10
protect
the
cooling system against
corrosion
The anti
freeze does not contain
any
glycerine
ethyl or methyl
alcohol
It will not
evaporate
or boil
away
and
can be used
with either
high
or low
temperaturethennoslat
It
flows
freely
transfers heat
effi
ciently
and
will
not
clog passages
in
the
cooling
system
The anti freeze must not be
mixed
with
other
products
This coolant can be used
through
out
the
seasons of the
year
Whenever
coolant is
changed
the
cooling
syslem
should be flushed and
refilled with a new coolant
Check the level See the instruc
