I topped up daughter's Fiat 500 with some antifreeze (a few weeks ago the
level was lot - and I tipped up with water so I was keen to get some
concentrate in) I ended up brimming it.
Will it matter? Does it need some air space? Should I syphon some out to
bring it down to the max mark? Or will it sort itself out?

The water will expand, but the tank must have an overflow. Even a Fiat!

It just gurgles out when it needs to.

Yes fiats have an overflow. It might turn the bits of the car it runs down a
funny colour though!

Greeny yuck comes to mind.

There should be a MAX and MIN mark on the reservoir.

If you fill to the brim, the excess will blow out through
the overflow, but when the engine cools the hoses will
contract a bit as the water shrinks, whereas if you fill
to the correct level when cold, the hoses will be at their
correct diameter. Not sure if this additional flexing
shortens their lives.

Have sucked some out - now at the Max mark when cold.
