DIESEL
FUEL
Use a
diesel
fuel
that
meets
the
requirements of
No.
2-D
SAE J 3
[3
and
has
a Cetane
rating
of
#45
or higher grade of
diesel
fuel
according
to
ASTM
D975
Care
Of
The
Fuel
Supply
Use
only
clean
diesel
fuel!
The
clearance
of
the
components
in
your
engines
fuel
injection
pump
is
very
critical;
invisible
dirt particles
which
might
pass
through
the
primary
and
sec-
ondmy
filters
can
damage
these
finely
machined
parts.
It
is
important
to
buy
clean fuel,
and
keep
it
clean.
The
best fuel
can
be
rendered
unsatisfactory
by
careless
handling or
improper
storage
facilities.
To
ensure
that the
fuel
going into
the tank
for
your
engine's
daily
use
is
clean
and
pure,
the
following
practice
is
advisable:
Purchase a
well-known
brand of
fuel.
The
use
of additives
to
combat BACTERIAL
growth
in
the
fuel
tank
is
recommended
such
as
Bio-Bor
and
an
additive
such
as
Diesel
Kleen
+ Centane Boost
to
help
restore lubricity back
into
the
diesel
fuel
when
an
Ultra
Low
Sulfur
diesel
is
being
used.
Install
and
regularly
service a
good,
visual-type
fuel
filtedwater separator between
the
fuel
tank
and
the
engine.
The Raycor
500
MA or 230
RMAM
are good
examples
of
such
filters.
A
10
micron
filter
element
is
recommended.
ENGINE
OIL
Use a
heavy
duty
diesel
oil
with
an
API
classification of
CF,
CG-4,
CH-4
or
CIA. Change
the
engine
oil
and
filter
after
an
initial
50
hours
of break-in operation.Then
follow
the
oil
and
filter
change
intervals
as
specified
in
the
MAINTENANCE
SCHEDULE
in
this manual.
Westerbeke
Corporation does
not
approve
or
disapprove
the
use
of synthetic
oils.
If
synthetic
oils
are
used,
engine
break-in
must
be
performed
using conventional
oil.
Oil
change
intervals
must
be
as
listed
in
the MAINTENANCE SCHEDULE section of
this
manual
and
not
be
extended if
synthetic
oils are
used.
NOTE:
The
information above supersedes all previous
statements
regarding
synthetic
oil.

ENGINE
COOLANT
WESTERBEKE
recommends
a
mixture
of
50%
antifreeze
and
50%
distilled
water.
Distilled
water
is
free
from the
chemicals that
can
corrode
internal
engine
surfaces.
The antifreeze
performs
double
duty.
It
aHows
the engine
to
nm
at
proper
temperatures
by
transferring heat away
from
the
engine
to
the
coolant,
and
lubricates
and
protects
the
cooling
circuit
from
rust
and
corrosion.
Look
for
a good
quality
antifreeze
that
contains
Supplemental
Cooling
Additives
(SCAs)
that keep the
antifreeze
chemicalJy
balanced, crucial
to
long
term
protection.
The
distilled
water
and
antifreeze
should
be
premixed before
being
poured
into
the
cooling
circuit.
NDTE:
Lookfor
the
new
environmentally-friendly
long
lasting
antifreeze that
is
now
available.
PURCHASING
ANTIFREEZE
Rather
than
preparing
the
mixture, WESTERBEKE
recommends
buying
the
premixed
antifreeze
so
that
so
that
when
adding
coolant
the
mixture
will
always
be
correct.
There are
two
common
types
of
antifreeze,
Ethylene Glycol
(green)
and
Propylene
Glycol
(red/purple),
either
can
be
used
but
do
not
mix
the
two
and if
changing
from
one
to
another,
flush
the engine
thorougbly.
Premixed antifreeze for DIESEL Engines:
Specification #ASTM D53456.
MAINTENANCE
Change
the
engine
coolant every
five
years
regardless of
the
number of
operating
hours
as
the
chemical
additives that
protect
and
lubricate
the
engine
have
a limited life.
COOLANT
RECOVERY
TANK
The
coolant
recovery
tank
aIJows
for
the
expansion
and
contraction of
the
engines
coolant
during
engine operation
without introducing
air
into the
system.
This
recovery
tank
is
provided
with
fresh
water cooled
models
and
with
the
fresh
water
coolant conversion kit and
must
be
installed before
operating
the
engine.
