The antifreeze liquid is advised for all kinds of climates: it enlarges the working temperature range, lowering the freezing point and increasing the boiling point.
When the temperature comes close to 0°C it is necessary, in order to avoid the risk of freezing, to make sure that the cooling lines are filled with antifreeze mixture. Otherwise, replace the cooling liquid with such a mixture.
Before carrying out the system filling with antifreeze mix, it is necessary to wash the cooling circuit.
The use of antifreeze liquid is recommended for which reference is made to the specific manuals for the mixing percentages in relation to the external temperature.
Concentrated coolant must be treated as special waste.
When disposing of used cooling liquid, keep to prescription of Authority locally in charge.
Check periodically that all devices containing water are filled with the correct quantity of anti-freeze if necessary.
Each time that the outer temperature drops below 0°C the water (fresh or sea) inside the ducts may freeze and consequently break.
All systems and equipment containing water, both sea water systems (engine cooling system, generators cooling system, etc..) and fresh water systems (windscreen wipers, fresh water pump, etc..) may run this risk.
