What does a radiator cap do?

The radiator cap is located at the top of the expansion tank or radiator. Various conditions and malfunctions can cause the pressure in your cooling system to rise too far. Does it come to around 1.2 bar? Then the pressure cap will open. Coolant then escapes from the cooling system via the pressure relief valve. Did you lose or damage your radiator cap? If so, replace it immediately before sailing again! Without such a seal, the cooling capacity of your engine is limited to 100 degrees Celsius. Without pressure, your engine can heat up much faster.
