DIESEL FUEL, ENGINE OIL AND ENGINE COOLANT
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 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 pruticles which might pass through the primary and sec-
ondary filters can damage these finely machined pm1s. 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 gro\Yth in the fuel
tank
is
recommended 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 regulru·Iy 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 heavy duty diesel oil with an API classification of CF,
CG-4, CH-4 or Cl-4. Change the engine oil and filter after an
initial 50 itours 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.
SAE OIL VISCOSITY
For all temperature ranges: SAE lSW-40 or SAE lOW-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
cylinder walls. Prestone andZerex 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 SCHEJ?ULE 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 iife.
COOLANT RECOVERY TANK
The coolant recovery tank 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.
r
NOTE:
771is tank, •vith its short run of plastic hose, is best
located at or above the level of the engines manifold, but it
can be located below the level of the engines manifold if the
particular installation makes this necessary.
