Coolant filling

  Important
  • Before proceeding with operation, read Par. 3.2.2.

 

  Warning

  • An anti-freeze protection liquid (ANTIFREEZE) - mixed with decalcified water - must be used.
  • The freezing point of the refrigerant mixture depends on the amount concentration in water.
  • As well as lowering the freezing point, the antifreeze also raises the boiling point.
  • A 50% mixture is recommended to ensure a general level at protection prevents the formation of rust, galvanic currents and calcium deposits.



NOTE: Before proceeding with any operation on the engine, stop it and allow it to cool.

Warning
Presence of steam pressurized coolant danger of burns.

  1. Loosen the cap A and fill the radiator with coolant composed of:
    50% ANTIFREEZE and 50% decalcified water.
  2. Top liquid up until the pipes inside the radiator are covered by about 5 mm. Do not overfill the radiator, but leave room for the coolant to expand.
  3. For engines equipped with expansion tank, pour in fluid until reaching the max level mark.
  4. Loosen the screw C, release any air and tighten the screw C (Tightening torque of 8 Nm - Fig. 4.6).
  5. Re-tighten the cap A.
  6. After a few hours of operator, stop the engine and allow the liquid to cool returns to a ambient temperature and check the coolant level again.
