The main purpose of coolant is to transport heat from the hot parts of the engine to the
radiator and to protect the cooling system from corrosion.
In addition to this, the coolant must:
•
Protect against pitting and cavitation erosion damage of the water pump and cylinder
liners.
•
Protect against freezing and boiling.
•
Prevent formation of scale, sludge deposits and clogging.
•
Be harmless to polymer materials and seals in the cooling system.
•
Maintain its liquid properties in cold climates.
Many engine failures can be traced back to a problem in the cooling system. If the coolant
level is allowed to go below the bottom of the tank, there is the risk of the engine shutting
down. See the operators manual for more information on the warning functions.
Note:
Always dispose of coolant according to Federal or local regulations. Take all used
coolant to a recycling or waste collection center.
Coolant mixture consisting of an antifreeze solution in water should be used year-round to
provide freeze and boil-over protection as well as providing a stable environment for seals
and hoses.
Note:
DO NOT use antifreeze formulated for automobile gasoline engines. These have a
very high silicate content that will clog the radiator and leave unwanted deposits in the
engine.
