ENGINE COOLING SYSTEM
Checking the cooling fluid level
Cooling fluid absorbs the heat from the thermic group (piston, cylinder, head) and
conveys it to the exterior atmosphere through radiator. For a correct operation of the
cooling system it is of utmost importance the periodical check of fluid level.
The lack of the heat exchange means (water) between thermic mass and
radiant mass could cause overheating of the cylinder-piston assembly with
consequent seizure and, the worst, damages to the crankshaft assembly.
However if engine overheating is noticed, check that radiator is completely filled up.
Check of radiator level must be performed with cold engine (see page D.32).
If for any reason you have to operate on a hot engine, take care to slowly discharge
pressure.
The radiator cap (1) is provided of two unlocking positions, the first being for the
previous pressure discharge.
Opening the circuit without taking care of above directions could
cause scalds to the operator and other people around.
TE-SMR: Because the cooling fan (2) can be activated even when the
start switch is in OFF position, always keep at a safe distance from the
fan vanes.
