11.2.1 Cooling system

The antifreeze liquid is advised for all kinds of climates: it increases the working temperature range, lowering the freezing point and increasing the boiling point.
When the temperature comes close to 0°C (32°F) it is necessary, in order to avoid the risk of freezing, to make sure that the cooling lines are filled with antifreeze mixture. If not, replace the cooling liquid with such a mixture.
Before filling the system with antifreeze mix, it is necessary to wash the cooling circuit.

Engine cooling systems should be filled with a mixture of 60% water and 40% antifreeze throughout the year to ensure protection against corrosion and freezing down to -27°C (-17°F).
At the beginning of the cold season, the antifreeze content of the coolant must be checked and increased according to the expected outside temperatures.

ENVIRONMENT

Concentrated coolant must be treated as special waste.
When disposing of used coolant, abide by the regulations of the local authority.

NOTE

For information concerning the type of anti-freeze or additive to be used, please refer to the technical documentation supplied by the Manufacturer.

CAUTION

Do not use only water as a cooling liquid, as it is corrosive at the engine operating temperatures and does not protect suitably against boiling and freezing.

CAUTION

We recommend you to use technical liquids approved by the system Manufacturer. Always avoid antifreeze concentration to drop below 40% in volume. Replace the whole cooling liquid according to the schedule indicated by the Manufacturer.
