THERMOSTAT
A
wax
pellet
type
thermostat
is
mounted
in
the
thermostat
housing
at
the
cylinder
head
water
outlet
The
function
of
the
thermostat
is
to
control
the
flow
of
coolant
facili
tating
fast
engine
warm

and
regu
lating
coolant
temperature
The
ther
mostat
is
designed
to
open
and
close
at
predetermined
temperatures
and
if
not
operating
properly
should
be
re
moved
and

INSPECTION
A

thermostat
will
prevent
the
cooling

from
functioning
properly
If
the
thermostat
sticks
in
the
open
position
the
engine
warms
up
very
slowly
If
the
thermostat
sticks
in
the
closed
position
over

will
result
Therefore
the
ther
mostat
should
be
inspected
to
make

that
it
is
in
good
condition

RADIATOR
The
radiator
is
a
conventional
down
flow
type
having
top
and
bottom
tanks
to
distribute
the
coolant
flow
uniformly
through
the
vertical
tube
of
radiator
core
The
radiator
filler
cap
is
designed
to
maintain
a
pre
set
pressure
0
9
kg
cm2
13
psi
above
atmospheric
pressure
The
relief
valve
consisting
of
a
blow
off
valve
and
a
vacuum
valve
helps
to
prevent
the
coolant
from
boiling
by
giving
pressure
to
it
How
ever
when
the
pressure
is
reduced
below
atmospheric
pressure
the
vacu
um
valve
allows
air
to
re
enter
the
radiator
preventing
the
formation
of
a
vacuum
in
the
cooling
system
