The
water

pump
is
of

a

centrifugal

is
mounted
on
the

engine

body
The

bearings
are

permanently
lubricated

and
sealed

to

prevent

and

entry
of

The

pump
is

provided
with
an

impeller
which

a
steel

shaft

The

steel
shaft
rotates

together
with

the

The

torque

keeps
the

to

conserve

It
also

helps

For

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
Tern

coupling
however

is

properly
changed

with
the

cooling
requirement

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
silicon
oil
is
forwarded

to
the

groove
that

con

dition

When
the

valve
closes
silicone
oil
is

not

supplied
to
the

driving
chamber

oil
in

the

driving
chamber
is

accumu

lated
on

periphery
due
to
the

centrif

ugal
force
and
led

into
the
reserve

chamber
Now

oil
is

eliminated
from

the

driving
chamber

and
the

system
is

placed
under
OFF
condition

With
this

system
when
fan

cooling

is
not

required
the

output
loss
is

minimized

and
noise

can
be
far

reduced
