4.6 Coolant filling

• Before proceeding with operation, read
• 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.
NOTE: Before proceeding with any operation on
the engine, stop it and allow it to cool.
• 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 50 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.
