Cooling System 39
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 de-
posits and clogging.
•
Be harmless to polymer materials and
seals in the coolant system.
•
Maintain its liquid properties in cold
climates.
Coolant should consist of these three com-
ponents:
•
Clean water.
•
Additives.
•
Antifreeze (Glycol).

dling, mixtures and specifications.
