Thus, mineral salt deposits formed in the radiator by evaporated water are also minimised and the
efficiency of the cooling system is not affected.
When the temperature drops below zero degrees centigrade, check the cooling system frequently and
add more antifreeze if needed (up to 60% max.).
Use distilled water in the coolant mixture to avoid damaging the engine.
Depending on the freezing temperature of the coolant mixture you wish to achieve, add the percentage
of coolant indicated in the following table to the water:
F
REEZING POINT
C° (-°F)
Specification Desc./Quantity
-20° (-4) Coolant 35% by volume
-30° (-22) Coolant 45% by volume
-40° (-40) Coolant 55% by volume
