Coolant leak

It seems there is a coolant leak from the expansion tank. I'm not sure where exactly though. If I top it off, the tank will be empty in 2 - 3 days, but I don't see traces of a massive leak. The hoses look OK to me, so I'm thinking a crack in the tank that leaks under pressure.
Has anyone dealt with a similar problem? Should I replace #3 in the diagram as well?
