Thermostatic valve
Low temperature operation
When the temperature of the coolant is lower than the set
values, the coolant coming from inside the engine (1) ricir-
culate directly towards the centrifugal pump (2).
High temperature operation.
When the temperature of the coolant is above the set val-
ues, the thermostatic valve partially shuts in or totally the
recirculation towards the pump and opens the path towards
the coolant/sea water heat exchange (3).
Water pump
The water pump has its own seating within the crankcase
and is set into rotation by poli-V belt.
Additional expansion tank
In some cases an additional tank may be fitted with the pur-
pose to increase the available expansion volume; the con-
nection to the main tank can be made by a pipe fitted on the
hose holder of the union pipe “overflow”. The plug of this
tank has to be equipped with a pressure relief valve to
enable liquid downflow while the engine is cooling.
This second tank, usually made in transparent material and
not pressurized, can be installed in order to have a better
access to check its level, that anyway has to be periodically
checked also in the main tank.
