FUEL, ENGINE OIL AND ENGINE COOLANT
FUEL
A
CAUTION:
Use only No.2·D (SAE J313} diesel that
has a Cetane rating of 145 or higher. Grade of diesel
according to ASTM 8975.
Care Of The Fuel Supply
Use only clean 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 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, Coast Guard approved
metal bowl type filter/water separator between the fuel tank
and the engine.
ENGINE OIL
Use a well known brand oflubricating oil, with an API
classification and SAE as listed in the SPECIFICATION
pages of this manual
Change the 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 of
the use of synthetic oil. If synthetic oil is used, engine
break-in must
be
performed using convential oil. Oil change
intervals must
be
as listed in the MAINTENANCE
SCHEDULE section of this manual and the change intervals
are not to be
extended if synthetic oil is used
NOTE:
The
information above supersedes all previous
statements regarding synthetic oil.
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. It also lubricates and protects the
cooling circuit from rust and corrosion. Use a good quality
antifreeze that contains supplemental cooling additives
(SCAs) that keep the antifreeze chemically balanced, crucial
to long term protection.
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.
COOLANT RECOVERY TANK
A coolant recovery tank kit is supplied with each generator.
The purpose of this recovery tank is
to:
Bnow
for engine
coolant expansion and contraction during engine operation
without the lass of coolant and without introducing air into
the cooling system.
