Fuel, Engine 011 And Engine Coolant - Westerbeke SBEG Series Operator's Manual

FUEL, ENGINE OIL AND ENGINE COOLANT
GASOLINE
A
CAUTION:
Only use unleaded fuel with an octane
rating of
89
or higher. Leaded fuel will cause serious
hann to your engine and violate your warranty.
Care Of The Fuel Supply
Use only clean, well filtered gasoline. The passages in the
carburetors and the clearances in the fuel injection equipment
are very critical for proper fuel flow. Small contaminants not
captured in the primary filter/water seperator can clog these
passages and affect these clearances, 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 heavy duty engine oil with an API classification of SJ.
Change the engine oil and filter after an initial 50 hours of
break-in operation, and every 100 hours of operation
thereafter. An oil viscosity of SAE 15W-40 is recommended
for this engine in all conditions.
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
tenn protection.
The water and antifreeze should be premixed before being
poured into the cooling circuit.
NOTE:
Use the new environmentallyjriendly, long lasting,
antifreeze that is now available.
A proper 50/50 mixture as recommended will protect the
engine coolant to temperatures of -40'F.

COOLANT RECOVERY TANK
A coolant recovery tank kit is supplied with each generator.
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.
