General information
BE SURE TO KEEP THE DRAINED COOLANT
AWAY FROM CHILDREN AND PETS.
IT IS SWEET TASTING, AS WELL AS EXTREMELY
POISONOUS, AND IS VERY ATTRACTIVE TO
CHILDREN AND PETS.
Use extra caution not to spill the coolant on any
hot parts of the engine. It is flammable, and can
emit invisible, noxious fumes.
Always wear rubber or latex gloves when servic-
ing the cooling system.
The coolant is made up of 50% water and 50%
antifreeze.
This mixture is ideal for most running temperatures
and ensures good protection against corrosion.
It is advisable to keep the same mixture also in the hot
season, since in this way losses due to evaporation
are reduced and it is not necessary to top up very
frequently.
The mineral salt deposits left in the radiator by evapo-
rated water are thus reduced and the efficiency of the
cooling system remains unchanged.
If the outdoor temperature is below 0°C, check the
cooling circuit frequently and if necessary increase the
antifreeze concentration (up to maximum 60%).
CAUTION
Use only distilled water when topping off the
cooling system. This will reduce damage to the
engine.
WARNING
The coolant is very hot.
Do not remove the filler cap (1) when the engine is
hot since the coolant is under pressure and it will
splash out violently.
If it gets in contact with the skin or with your
clothing, it may cause severe burns.
WARNING
Be aware of the risk of burns from the coolant.
Check the coolant level and top up the expansion
tank only after the engine has thoroughly cooled.
Do not use your fingers or any other object to
check if there is enough coolant.
