Diesel Fuel, Engine Oil And Coolant - Westerbeke 10.0 EGTD Operator's Manual

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 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 recqm-
mended such as Bio-Bor and an additive such as Diesel
.Kleen + Cetane Boost to help restore lubricjty 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.
E~&GINE 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
100 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 infonnation above. supersedes all previous
statements regarding synthetic oil.
SAE OIL VISCOSITY GRADES
For all temperatures ranges: SAE lOW-40 or 15W-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 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.
