Run the engine with radiator cap off, making sure it's warm enough
for the thermostat to be open. You can usualy see the flow
into the radiator top hose.
As regards dumping the water into the expansion bottle. "Offically"
the water lever in the rad should be about 1/2in under the
bottom of the neck that the cap fits on to. The expansion bottle
should be something like 3/4 full.
In reality these levels vary quite a bit and some trial and error
is required to find out what levels your vehicle is happy with.
It's not unknown for the engine to dump water out of the overflow
for no apprent reason and not do it again for ages, though regular
overflowing needs to be investigated.
