3232861 - 1088B ENGINE COOLING RADIATOR

Supply tank

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 the leakage test, see   0510C30  cooling system - tightness test .

Radiator

This consists of a radiating mass and two side chambers acting as the coolant to inlet and outlet. The tubes and fins of the radiating mass are of aluminium, and the reservoirs are of plastic.
