COOLING
SYSTEM
REMOVAL
• Remove
the
fairing. (Refer
to
page 7-1.)
• Drain
the
cooling solution by removing drain plug.
(Refer
to
page 3-1.)
• Disconnect
water
hoses. (Refer
to
page 3-4.)
• Remove
the
radiator.
INSPECTION
Before removing
the
radiator and draining coolant, inspect
the
following
two
items.
1. Test
the
cooling system
for
tightness by using
the
radiator
tester as follows:
Remove
the
radiator cap, and
connect
the
tester
to
the
filler.
Give a pressure
of
about
100 kPa (1.0 kg/cm
2
)
and
see if
the
system holds this pressure for 10 seconds.
If
the
pressure
should fall during this
10 second-interval, it means
that
there
is
a leaking point
in
the
system;
in
such a case, inspect
the
entire
system and replace
the
leaking
component
or
part.
2. Test
the
radiator cap for relieving pressure by using
the
radiator
tester
in
the
following manner: Fit
the
cap
to
the
tester, as shown, and build up pressure slowly by operating
the
tester. Make sure
that
the
pressure build-up stops
at
110 ± 10 kPa
(1.1
±
0.1
kg/cm
2
)
and
that,
with
the
tester
held standstill,
the
cap
is
capable
of
that
pressure
for
at
least
10 seconds. Replace
the
cap
if
it
is
found
not
to
satisfy
either
of
these
two
requirements.
Radiator cap valve release pressure:
110 ±
10
kPa
(1.1 ± 0.1 kg/cm
2
)
3.
Road
dirt
or
trashes stuck
to
the
fins must be removed. Use
of
compressed air
is
recommended for this cleaning. Fins
bent
down
or
dented can be repaired
by
straightening
them
with
the
blade
of
a small screwdriver.
4. Any
water
hose found
in
cracked condition
or
flattened
must be replaced.
INSTALLATION
The radiator
is
reinstalled
in
the
reverse order
of
the
removal
procedure.
After
installing
the
radiator, be sure
to
add cooling
water: refer
to
page 2-8 for refilling information.
