BLEEDING, COOLING
CIRCUIT
To bleed the air, with the
circuit completely drained
from the coolant, proceed as
follows:
BLEEDING OF THE LEFT
SIDE
• Remove the cap on the
bleeding coupling (A).
• Fit a tube in the coupling
(A) of the bleed nipple on
the cylinder head.
• Refill the expansion reser-
voir with coolant, as descri-
bed: (P. 11).
• Release and remove the
filler (B).
• Pour some coolant in the
main radiator (left).
• Slacken the coupling (A)
and go on refilling the main
radiator until some liquid
would drip off the tube (with
regular flow).
• Now, close the bleed nipple
(coupling - A) and fill in up
to the rim of the main
radiator.
• Slacken the bleed screw (C),
until some liquid drips off with
regular flow.
• Close the screw and top up
the liquid.
• Open the bleed nipple on the
cylinder head and check the
tubes for liquid dripping,
showing that the bleeding
has been correctly carried
out.
• Close the coupling (A) back.

ght side and, keeping it in this
position, slightly slacken the
screw (D), to let any remaining
air out of the right radiator.
• Tighten the bleed screw (D),
