Every two years
Before proceeding the emptying of the system,
Perform the following operations in advance:
• Remove the ignition switch cover (see “Engine
coolant level check”);
• Place a container under the engine to collect the
used coolant;
• Open the expansion tank cap;
• Remove the coolant discharge screw (1) situa-
ted on the coolant pump (2), thereby letting the
coolant flow out.
Wait for the engine coolant to completely flow out.
Collect the engine coolant in an appropriate
container. Do not scatter the engine coolant
into the environment.
Tighten the engine coolant discharge plug (1) to the
specified torque, after having checked the condition of
the gasket.

Fill the cooling system with the appropriate liquid
described in table (see page 11 of this chapter) until
the level is between the «MIN» mark found on the
expansion tank and the lower part of the frame tube
(see figure below).
Close the cap.
Switch on the engine and keep it running until the
water becomes hot enough to automatically switch on
the electric cooling fan. Switch off the engine. Wait
some minutes for the engine to cool down.
Carefully check for leaks, blow-bys, dama-
ged tubing, etc. If there are leaks or damage
in the cooling system, proceed with the
overhaul as described in the chapter
“Cooling system”.
Check once again the level of the coolant inside the
expansion tank (3).
It should be between the «MIN» mark found on the
expansion tank and the lower part of the frame tube, as
shown in the figure.
f the level is inferior to the «MIN» mark, top up the coo-
lant level by pouring new coolant into the filler hole.
