Cooling Fluid Level - PIAGGIO MP3 LT 400 i.e. Instruction Manual

Cooling fluid level (03_12, 03_13, 03_14, 03_15)

The engine cooling system operates by forcing circulation of fluid. The cooling circuit
contains about 2 litres of coolant consisting of a mixture of 50% de-ionised water and
glycol ethylene-based antifreeze solution with corrosion inhibitors. Recommended
coolant: supplied with the vehicle, already mixed and ready for use. For proper engine
functioning, the coolant temperature must be between the 4th and 7th lit segment, as
indicated by the instrument «D» on the digital instrument panel. When the 9th segment
lights up, the icon and all the segments start flashing; stop the engine, let it cool down
and check the fluid level; if the result is normal, take your vehicle to an Authorised
Piaggio Service Centre.

The fluid inspection should be carried out every 6,000 km when the engine is cold,
following the methods indicated below.
a) Rest the vehicle in vertical position on the stand and remove the screw of the ex-
pansion tank cap shown in the photo
b) Remove the expansion tank cover «A», turning in anticlockwise.
c) Look inside the expansion tank: the fluid level must always be between the min and
the max level
d) If the coolant level is near the minimum mark, top up when the engine is cold.
If the coolant needs to be topped up frequently or the expansion tank is completely

dry, check the cooling system to find the cause of the problem. It is therefore indis-
pensable to have the cooling system checked at an Authorised Piaggio Service
Centre. The coolant should be replaced every 2 years. Take your vehicle to an Au-
thorised Piaggio Service Centre for this operation.
N.B.
SHOULD THE 9th SEGMENT OF THE COOLANT TEMPERATURE INDICATOR
COME ON DURING A NON-DEMANDING RIDE, SHUT OFF THE ENGINE AND LET
IT COOL DOWN. THEN CHECK THE COOLANT LEVEL; IF THE LEVEL IS OK,
CONTACT AN AUTHORISED SERVICE CENTRE.
