• Place engine on horizontal surface to ensure accurate
measurement of filling.
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 cooled exhaust manifold B
with coolant composed of: 50% ANTIFREEZE and 50%
decalcified water.
2. Loosen the screw C release any air and tighten the screw
C (Tightening torque of 8 Nm - Fig. 4.7).
NOTE:
The
MAX
B is in correspondence of capscrew C,
complete the coolant refilling procedure
as soon as the coolant starts leaking out

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.
