DIESEL
FUEL
Use
a diesel
fuel
that meets
the
requirements of
No.2-D
SAE
J
313
and
has a Cetane rating of
#45
or
higher.
Grade
of
diesel
fuel
according
to
ASTM
0975.
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 f
fuel,
and keep it clean. The best
fuel
can
be
rendered
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
230
or
245
are good examples of
such
a
filter.
Micron filter rating
of #
IO
is
recommended.
ENGINE
OIL
Use
a heavy
duty
engine
oil
with
an
API
classification of
CF,
CG-4,
CH-4 or CI-4. Change
the
engine
oil
and
filter after
the
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
in
this
manual
and
not
be
extended if
synthetic oils are
used.
NOTE:
The
in/ormation above supersedes all statements
regarding synthetic oil.

ENGINE
COOLANT
UNIVERSAL 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 allows
the
engine
to
run
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 chemically
balanced,
crucial
to
long
tenn
protection.
The distilled water
and
antifreeze should
be
premixed
before
being
poured
into
the
cooling
circuit.
NOTE:
Laokfor
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.

A coolant recovery

kit
is
supplied
with
each
UNIVERSAL 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.
