Remark
Cooling system
Cooling method Primary Cooling:
Automotive type glycol-based
corrosion-inhibited antifreeze.
Removes heat from engine.
Secondary Cooling:
Water-cooling (marine applications).
External Radiator (land applications).
Heat is transferred to hot water
cylinder(s) and space heater(s).
Heat exchangers Internal exhaust and marine heat
exchangers.
Requires external coolant pump
and seawater pump.
Exhaust temperature 80°C nominal, 95°C maximum.
Cooling system extracts heat
from exhaust.
