ANTI
FREEZE

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

model

Tem
coupling
is

a

type
of
fan

coupling
which
is

provided
with
a

temperature
control

system

The
conventional

coupling
always

slips
the
fan
at

a

high

speed
under
a

constant

ratio

regardless
of
the

engine

cooling

requirement

The

slipping
ratio
of
the
Tem

coupling
however
is

properly
changed

with
the

cooling
requirement

ON
denotes
that

cooling
is

required
and
the
fan

operates
up
to

about
2

900rpm
When

high

not

required
during

the

oper

ation

is

placed

and

The
coiled
bimetal
thermostat

installed
on
the
front
center

portion
of

the
Tem

coupling
detects

temperature

of
air

passing

through
the
radiator

The
air

temperature
is

directly

relative

to
the

engine
coolant

tempera

ture

and
the
inside
slide
valve

is

opened
or

closed
as

required
and
thus

the
ON

control
is

performed

When
the
air

temperature
rises

the

bimetal
is

expanded
and
the
valve
is

opened
silicone

oil
is
forwarded

to
the

groove
that

When

OPERATION

The
radiator
reservoir
tank
is

mounted
to
the

right
hand
side
core

support
through
the
bracket
When

the

coolant

temperature
in
the
radiator

rises

and

pressure
builds

up
to
an

extent
the

pressure
relief
valve

provided
in

the
radiator

cap

opens
to

release
excess
coolant
into

the
re

servoir

tank
When
the
coolant

temper

ature
lowers
and

pressure
decreases
in

the
radiator
the
vacuum
valve

provid

ed

in
the
radiator

cap
opens
to
allow

the
