3232861 - 1088B ENGINE COOLING RADIATOR

COMPONENT DESCRIPTION

ENGINE COOLANT RESERVOIR

Specifcations

OperationIn addition to supplying the system, the reservoir also absorbs the variations in volume of the cooling liquid, as the engine temperature varies and the coolant vapours are condensed thereby avoiding topping up.

Through a specific calibrated valve, contained in the pressurized cap:

• air emerges from the collection circuit from the pipe coming from the thermostat
• air enters when the circuit is in a vacuum (because of the engine cooling).

The maximum pressure reached in the engine cooling circuit is 1.4 bar.
