DIESEL
FUEL
Use a diesel fuel that meets the requirements ofNo.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 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
#10
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 infomwtion 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 term protection.
The distilled water and antifreeze should be premixed before
being poured into the cooling circuit.
NOTE:
Look
for
the new environmentallyjriendly 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 tank 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.
