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.
