DIESEL
FUEL
Use
fuel
that
meets
the
requirements
or
specifications
of
Class
2-D
(ASTM),
and
has
a
cetane
rating
of
#45
or
better.
Care
of
the
Fuel
Supply
Use
only
clean
diesel
fuel!
The
clearance
of
the
components
in
your
fuel
injection
pump
is
very
critical;
invisible
dirt
particles
which
might
pass
through
the
filter
can
damage
these
finely
finished
parts.
It
is
important
to
buy
clean
fuel,
and
keep
it
clean.
The
best
fuel
can
become
unsatisfactory
by
careless
handling
or
improper
storage
facilities.
To
assure
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.
Install
and
regularly
service
a
good,
visual-type
filter/water
separator
between
the
fuel
tank
and
the
engine.
Raycor
models
220
or
225
are
good
examples
of
such
spin-on
filters.
ENGINE
OIL
Use
a
heavy
duty
engine
oil
with
an
API
classification
of
CF
or
CG-4.
Change
the
engine
oil
after
an
initial
50
hours
of
break-in
operation,
and
every
100
hours
of
operation
thereafter.
For
recommended
oil

A
CAUTION:
Do
not
allow
two
or
more
brands
of
engine
oil
to
mix.
Each
brand
contains
its
own
additives;
additives
of
different
brands
could
react
in
the
mixture
to
produce
properties
harmful
to
your
engine.
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,
as
it
allows
the engine
to
run at proper temperatures by transferring heat
away
from
the engine
to
the coolant.
It
also 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 chemically
balanced, crucial
to
long term protection.
The distilled water and antifreeze should
be
premixed before
being poured into the cooling circuit.
NOTE:
Use
the
new environmentally-friendly
long
lasting
antifreeze that
is
now available.
Antifreeze mixtures will protect against
an
unexpected freeze
and
they
are
beneficial
to
the engine's cooling
system.
They
retard rust and add
to
the life of the circulating pump
seal.

COOLANT
RECOVERY
TANK
A coolant recovery tank kit
is
supplied with each
WESTERBEKE diesel engine.The purpose of this recovery
tank
is
to
allow for engine coolant expansion and contraction
during engine operation, without the loss of coolant and
without introducing
air into the cooling
system.
This kit
is
provided
and
must be installed before operating the
engine.
NOTE:
This
tank,
with
its
short
run
of
plastic
hose,
is
best
located at or above
the
level
of
the
engine s manifold but it
can
be
located below
the
level
of
the engine s manifold
if
the
particular installation makes this
necessary.
