If
any
portion
of
the
heating
circuit
rises
above
the
engine's
own
pressure
cap,
the
a
pressurized
(aluruinum)
remote
expansion
tank
must
be
installed
in
the
circuit
to
become
the
highest
point.
The
remote
expansion
tanks part
number
is
24177.
Tee
the
remote
expansion
tank
into
the
heater
circuit
.
at
the
heater
connection,
choosing
the
higher

the
heater
and
plumb
a single
line
up
to
the
tanks location
and
the
other
back
to
the
engine's
flow
control. Install
the
remote
expansion
tank
in
a convenient
location
such
as
in a
sail
locker
so
the
fresh
water coolant
level
can
easily be
checked.
The
remote
expansion
ian!<:

fill
point.
The
plastic
coolant
recovery
tank
is
not
used
when
the
remote
expansion
tank kit is
installed,
since
this
tank
serves
the
same
function.
The
pressure
cap
on
the
engine's
manifold
should
be
installed
once
the
engine's
cooling
system
is
filled
with
coolant.
Finish
filling
the
cooling
system
from
the
remote
taDk
once
the
system
is
filled
and
is
free of
air
and
eXhibits
good
coolant
circulation.
During
engine
operation,
checking
the engine's coolant
should
be
done
at
the
remote
tank
and
not
at
the
engine
manifold
cap.
The
hose
connection
from
the
heater
to
the remote
expansion tank
should
be
routed
and
supported
so
as
to
rise
continuously
from
the
heater
to
the
tank,
enabling
any
air
in
.
the
system
to
rise.
