Fuel, Engine Oil And Engine Coolant - Westerbeke W-70GA 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
harm to your engine and violate your warranty.
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
filterlwater 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.
A
CAUTION:
00 not allow two
or
more brands
of
engine oil to mix. Each brand contains its own additives;
additives
of
different brands could react in the mixture
to produce properties harmful to your engine.
NOTE:
The engine compartment should have a gasoline fume
detector/alarm properly installed and working.
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.
The water and antifreeze should be premixed before being
poured into the cooling circuit.
NOTE:
Use the new environmentally-friendly, long lasting,
antifreeze that is now available.
A proper 50150 mixture as recommended will protect the
engine coolant to temperatures of -4O"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.
