GENERAL INFORMATION ENGINE COOLANT Use an anti-freezeengine coolant compatible with an aluminum radiator, mixed with distilled
coolant should be limited to 60Mixing beyond it would reduce its efficiencyIf the anti-freezeengine coolant mixing ratio
is below 50, rust inhabiting performance is greatly reducedBe sure to mix it above 50 even though the atmospheric temperature
does not go down to the freezing point BREAK-IN PROCEDURES During manufacture only the best possible materials are used and
all machined parts are finished to very high standard but it is still necessary to allow the moving parts to "BREAK-IN" before
subjecting the engine to maximum stressesThe future performance and reliability of the engine depends on the care and restraint
exercised during its early lifeThe general rules are as follows Keep to these break-in engine speed limits: Break-in engine
speeds Initial 10 hours: Less than V2 throttle After the engine has been operated for 10 hours the engine to full throttle
