2427385 - 1088B ENGINE COOLING RADIATOR

In addition to supplying the system, the reservoir also absorbs the variations in volume of the cooling liquid, as the engine temperature varies.

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).

For leak test and test on pressurized plug see Op. 0510C30. This consists of a radiating mass and two side tanks that allow coolant in and out.The tubes and fins of the radiating mass are of aluminium, and the reservoirs are of plastic.
