• Start the engine and let it idle.

• Place a container under the engine to gather any

coolant coming out of breather screw (5).

The coolant in the circuit is under pressure. To

avoid dangerous spurts, loosen breather screw (5)

slowly and moderately.

• Loosen breather screw (5) on thermostatic valve

(6); allow a moderate quantity of coolant to flow

out together with any air bubbles and then tighten

breather screw (5).

• Check the level of the fluid in expansion tank (2)

and then top up to the MAX level (see page 2-25

CIRCUIT BLEEDING for the bleeding).

• Ride a few kilometres until the engine reaches the

normal operating temperature.

Switch off the engine and allow the engine and the

exhaust system to cool down.

CAUTION

To refit the plastic parts follow the reverse procedure.

If coolant consumption is excessive, or if the

coolant runs out in the tank, check for possible

leakage from the circuit.

The coolant is harmful: DO NOT INGEST

KEEP OUT OF REACH OF CHILDREN

Only use nitrite-free anticorrosive and antifreeze

agents providing a protection at temperatures of

-35° C (-31° F) or lower
