Do not forget that the radiator can get very hot. When handling, be cautious and
wait for it to cool down after stopping the engine. Always use coolant (-30°C) for
light alloy engines for topping up the radiator.
The tubes into and out of the radiator should be regularly checked for dents,
cracks or leaks that could impair the ¬cooling system. For correct mainte-
nance of the engine, make sure it has the right level of coolant. To do this,
you can top up the radiator tank through the cap at the top (preferably with
the recommended coolant).
By loosening the coolant drain bolt at the bottom
of the water pump you can drain the coolant circuit
of the engine.
It is important to wait until the engine is at ambient
temperature to drain the radiator, to avoid any dan-
ger of burns.
The temperature switch
controls the start and
stop of the fan to ensure
the engine has the co-
rrect operating temp¬e-
rature.
It is important to be
aware if the motorcycle
is overheating and the
fan is not working. In
this case, it needs to be
replaced.
