I have never had an unsealed cooling system, but if it really is open to
the atmosphere I would suggest that an overflow tank will not work.
The water will overflow into the tank, but it will not
be sucked back into the radiator since no vacuum can develop in the
radiator.
I.e. the radiator will suck some in some air rather than coolant through
the tube.
Am I missing something?
