AntiFreeze/Coolant
CAUTION
Alcohol or Methanol base antifreeze or plain water are not recommended for use in
closed cooling section of cooling system at any time.
Because diesel engines are high compression engines and related higher engine operating
temperatures are created, the closed cooling system and engine, including related cooling
passages must remain as clean as possible to provide adequate engine cooling. This can
only be assured by using the proper antifreeze, water, additives and inhibitors. It is
recommended that the closed cooled section of the cooling system be filled with a low
silicate formula of ethylene glycol antifreeze in solution with deionized water. A low silicate
formula prevents antifreeze separation which causes a silicate gelatin to form. This gelatin
will block engine and heat exchanger passages causing engine overheating.
The coolant, if not premixed, should be mixed before being added to the closed cooling
system using a proper antifreeze together with deionized water. Common tap water or
softened water contains unwanted minerals which can leave large deposits in the system
that restrict the cooling system efficiency. In addition, additives and inhibitors introduced into
acceptable coolant solutions will form a protective film on internal passages and provide
protection against internal cooling system erosion.
The closed cooling section should be kept filled year-round with an acceptable
antifreeze/coolant solution. Do not drain closed cooled section for storage, as this will
promote rusting of internal surfaces. If engine will be exposed to freezing temperatures,
ensure that the closed cooled section is filled with a properly mixed antifreeze/coolant
solution, to protect engine and closed cooling system to lowest temperature to which they
will be exposed.
NOTE:
A greater than 50/50 antifreeze/coolant solution should never be used except when
operating where seawater temperatures are greater than 32 degrees C (90 degrees F), then
a 25 / 75 (antifreeze / water) solution can be used for improved cooling performance.
IMPORTANT: The antifreeze/coolant used in these marine engines must be a low
silicate ethylene glycol, containing special additives, and deionized, purified water.
Using other types of engine coolant may cause fouling of the heat exchangers, and
overheating of the engine. Do not combine different types of coolants without
knowing that they are compatible. Refer to the coolant manufacturer’s instructions.
Some acceptable types of antifreeze/coolants are listed in the following table. Refer to
Maintenance Schedules for respective change intervals.
