DIESEL
FUEL
Use
a diesel fuel that meets the requirements
of
No. 2-D
SAE
J 313 and has a Cetane rating
of
#4
5
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
secondary 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 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.
The
use
of
additives to
combat BACTERIAL growth
on
the fuel tank is recom-
mended
such as Bio-Bor and an additive such as Diesel
Kleen
+ Cetane 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
filter/water 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 good brand
of
engine oil having an
API
and
SAE
specification as stated
in
the SPECIFICATIONS section in
this manual. Change the engine oil
and
oil filter after the
initial
50
hours
of
engine break-in operation and then every
250 hours
of
operation thereafter.
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.

VISCOSITY
GRADES
For
all temperatures ranges:

or
l5W-40.
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
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 term protection.
The
distilled water and antifreeze should
be
premixed before
being poured into the cooling circuit.
NOTE:
Look
for
the new environmentally-friendly long lasting
antifreeze that is now available.
PURCHASING
ANTIFREEZE
Select a brand
of
antifreeze specified for diesel engines.
Antifreeze specified for diesel engines contains a special
additive to protect against cavitation erosion
of
the engine's ยท
cylinder walls. Prestone
and
Zerex are two nationally known
brands that offer antifreeze specifically for use
in
diesel
engines. Select the pre-mixed variety
so
that the correct
mixture will always
be
added to the cooling system when
needed. Change the antifreeze mixture according to the
MAINTENANCE
SCHEDULE
in
this manual.
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 allows 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.
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.
