Fuel, Engine Oil And Engine Coolaat - Westerbeke 3.5 SBCG Operator's Manual

FUEL, ENGINE OIL AND ENGINE COOLANT
GASOLINE
Use only unleaded gasoline with an octane rating of 89 or
higher. Higher octane is recommended. The use of lower
octane gasoline will adversly affect engine performance.
Ethanol blends must not exceed E-10.
When fueling, follow U.S. Coats Guard Regulations. Close all
hatches and companionways to prevent fumes from entering
the vessel. Ventilate properly after fueling and before starting
the generator or main engines.
Use only clean fresh fuel! 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. This filter rating must be 10 microns or
smaller.
ENGINE OIL
Use a heavy duty engine oil as called for in the
Specifications Section of this manual. 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 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 of this manual and.not extended if synthetic
oils are used.
NOTE: The information above supersedes all
previous statements regarding synthetic oil.
OVER· FILLING
CAUTION: The
oil
sump on this
generator's
engine can
unintenUonally be over-filled!
After shutdown, the oil in the engines internal pasages can
linger and take a number of hours to drain back into
the
sump. Allow at least
a
few hours f()r the oil to settle back
into the sump before checking the dipstick reading.
(Re-starting the engine is not a problem as
the
engine's
internal passages are well lubricated).
Over-filling the engine's sump will result in erratic operation,
and/or a smokey oil laden exhaust,
hard
starting and possible
no start.
ENGINE COOLANT
Engine coolant a 50/50 mixture of antifreeze
and
distilled
water. This coolant allows the engine to run at its proper
temperature by transferring heat from the engine to the
coolant. It also lubricates and protects the cooling system
from rust and corrosion. A 50/50 mixture of antifreeze and
distilled water will protect the engine to
-34"F (l.l2°C).
PURCHASING ANTIFREEZE
Rather than preparing the mixture, WESTERBEKE
recommends buying the premixed antifreeze so that when
adding coolant; the mixture will always be correct.
There are two common
types
of antifreeze, Ethylene Glycol
(green) and Propylene Glycol (red/purple). Either can be used
but do not mix the two and if changing from one to another,
flush the engine thoroughly.
COOLANT RECOVERY TANK
A,f.Oolant recovery
tank
kit is supplied with each generator.
The purpose of this recovery
tank
is to allow for engine
cool~
expansion and contraction during engine ()peration,
without the loss of coolant and without introducing
air
into
the cooling system.
NOTE:
This coolant recovery tank, with its short length of
hose, is best located at or above the cooling systems
pressure/jill cap.
