BLEEDING THE CIRCUIT:

• Remove the front outer shield, see (REMOVING

THE FRONT OUTER SHIELD).

• Remove the filter box, see (REMOVING THE

FILTER CASE).

• Open the expansion tank cap.

• Remove the protective cap of the bleeder nipple,

situated on the union tee of the cylinder head (1).

• Start the engine and leave it running at minimum

running speed.

• Place a container under the engine to collect the

coolant that will spill out from the bleeder screw

(5).

The coolant is pressurized; loosen the bleeder

screw (5) slowly and a little at a time in order to

avoid splashing dangerous fluids.

• Loosen the bleeder screw (5) on the thermostatic

valve (6); let a small quantity of fluid flow out,

together with any air bubbles, then tighten the

bleeder screw (5).

• Check the level of the coolant in the expansion

tank (2) and top up to the “MAX” level (to bleed it,

see page 2-24 BLEEDING THE CIRCUIT).

• Run the engine for a few kilometers until it

reaches normal working temperature.

Switch off the engine and wait until both the

engine and the exhaust system are cool.

CAUTION

Follow these steps in reverse order to refit the plastic

parts.

If coolant is used up too quickly and the expan-

sion tank becomes empty, check for leaks in the

circuit.

Coolant is harmful: DO NOT DRINK.

KEEP OUT OF REACH OF CHILDREN.

Only use nitrite-free antifreeze and anticorrosive

products that guarantee protection to at least -31

°F (-35 °C).

For information about the cooling system, see (COOL-

ING SYSTEM).
