Cooling fluid level (03_12, 03_13, 03_14, 03_15)
Engine cooling is carried out by a forced-circulation coolant system. The cooling circuit
holds coolant consisting of a mixture of 50% de-ionised water and 50% glycol ethyl-
ene-based antifreeze solution with corrosion inhibitors. The coolant supplied with the
scooter is already mixed and ready for use.
For the proper functioning of the engine it is necessary for the coolant temperature to
be maintained at about 90°C (indicator at mid-scale of instrument, approximately). If
the needle of the gauge enters the red zone, stop the engine, let it cool down and
check the coolant level; if the level is OK, contact an Authorised Service Centre.
Check coolant when the engine is cold as indicated in the scheduled maintenance
table, following the steps below
