Actually, if you had a hole in the cap the system wouldn't pressurize,
and you'd get almost nothing out of it.  I once drove about 20 miles
with my expansion tank cap loose before I figured out why I was running
slightly warmer than usual.  I lost maybe a cup of coolant, just what
thermal expansion pushed out the top.  Unlike the radiator there's no
flow in this location to create dynamic pressure.
