WATER CIRCUIT
This car has two water circuits, one for the water radiator equipped with a mechanical thermostat.
The thermostat opens completely at 87 ° C, so there is no need to mask the water radiator.
At the same time, a second circuit includes the gearbox exchanger and the cockpit heating, which is
not fitted with a thermostat and is therefore always open.
The water pump is mechanical and driven by an independent belt.
The radiator is fitted with a fan; it starts at 92 °C and stops at 90 °C.
There is no water pressure sensor; however, the expansion tank cap is rated at 1.4bar.
Homologation: do not drill the radiator.
As an option, it is possible to add a second radiator fan since 1st of January 2021. The part list is
available on the nomenclature.
